Dual fuel generators give you the flexibility to run on gasoline when you need maximum power output and switch to propane when you want cleaner burning, longer shelf life, and easier storage — and that flexibility is exactly why they’ve become the default choice for home backup and RV use. For most buyers, the Westinghouse WGen9500DF hits the sweet spot: enough running wattage to power essential household circuits, electric start, and transfer switch readiness without stepping up to the price and fuel appetite of the 13,000-watt class. If you’re powering an RV or camping rather than a house, the WEN DF280iX inverter is a quieter, lighter alternative, while the DuroMax XP13000EH is the model to beat if whole-home coverage is non-negotiable. The core tradeoff in this category is raw wattage versus portability and clean power — big open-frame units cost less per watt but are loud and heavy, while inverters are quiet and electronics-safe but top out much lower. Read on for the full breakdown of all 15 models.

Key Takeaways

  • WEN dominates the mid-range and inverter segments with six of the fifteen picks, and its CO Watchdog carbon monoxide shutoff appears on every recent model — a safety feature some larger competitors still treat as optional.
  • The 13,000-watt class (DuroMax XP13000EH, DuroStar DS13000MX) delivers the most whole-home coverage, but every model in that class weighs over 200 pounds and burns gasoline noticeably faster than mid-size units at equivalent loads.
  • Propane output drops roughly 10 percent versus gasoline on every model in this lineup, so buyers should size their generator to their propane numbers, not the headline gasoline wattage.
  • Westinghouse‘s remote electric start models (13,500 and 14,500 peak watt versions) offer the most convenience features per dollar in the home backup class, including transfer switch readiness and remote start from up to 260 feet away.
  • Inverter models under 5,000 watts — the WEN DF280iX, DF360iX, DF480iX, and PowerSmart 3800 — are the only picks safe for sensitive electronics, but none can realistically run a central AC unit or well pump.

More Details on Our Top Picks

  1. WEN 4,750-Watt 120V/240V Dual Fuel Portable Generator with Wheel Kit and Electric Start (DF475T)

    WEN 4,750-Watt 120V/240V Dual Fuel Portable Generator with Wheel Kit and Electric Start (DF475T)

    Best Value for Home Backup Basics

    View on Amazon

    The WEN DF475T earns its spot by covering the essentials of dual fuel without padding the price with features most homeowners never touch. A fuel-selection dial lets me switch between gasoline (3,800 running watts) and propane (3,500 running watts), which matters during outages when one fuel runs scarce. The electric start and included wheel kit put it a step above basic recoil-only units, and 11 hours of half-load runtime outlasts the smaller WEN DF280iX by a wide margin.

    Where it falls short of the Westinghouse WGen9500DF is raw capacity — this unit won’t run a well pump plus central AC simultaneously. Propane output also dips noticeably, so I’d size loads around the lower figure. It’s a tradeoff: less power, far less machine to store and move.

    Pros:
    • Simple dial-based switching between gasoline and propane
    • Electric start eliminates pull-cord hassle
    • Up to 11 hours of half-load runtime on a 4-gallon tank
    • Includes wheel kit, LPG hose, and 2-year warranty
    Cons:
    • Running wattage drops to 3,500W on propane, limiting heavy loads
    • Fuel-filled 4-gallon tank makes it heavy and awkward to maneuver despite wheels

    Best for: Homeowners who want reliable mid-size emergency power for fridges, lights, and a furnace fan without overspending

    Not ideal for: Households planning to back up an entire home through a transfer switch — the wattage ceiling is too low

    • Fuel Type:Dual Fuel (Gasoline / Propane)
    • Running Watts (Gasoline):3,800W
    • Surge Watts (Gasoline):4,750W
    • Running Watts (Propane):3,500W
    • Engine:224cc 4-stroke OHV
    • Start Type:Electric start with key
    • Tank Capacity:4 gallons
    • Run Time:Up to 11 hours at half load
    • Warranty:2 years
    Our verdict
    “The DF475T makes the most sense for buyers who want dependable dual fuel essentials for partial-home backup rather than whole-house power.”
  2. WEN 2,800-Watt Dual Fuel Inverter Generator, Quiet, Portable, and Lightweight with Fuel Shut Off and CO Watchdog (DF280iX)

    WEN 2,800-Watt Dual Fuel Inverter Generator, Quiet, Portable, and Lightweight with Fuel Shut Off and CO Watchdog (DF280iX)

    Best Compact Pick for Camping and Tailgating

    View on Amazon

    The WEN DF280iX stands out for what it doesn’t demand: space, muscle, or fuel. Its inverter design produces clean power safe for laptops and phones, which conventional open-frame units like the WEN DF475T can’t promise, and the fuel shutoff feature runs the carburetor dry before storage — a small detail that prevents the most common cause of a dead generator after a season in the garage.

    With 2,250 rated watts on gasoline (2,000 on propane), it powers a campsite or a few essentials, not a household. That’s the deliberate tradeoff versus the larger WEN DF680iX: you gain portability and quiet operation but give up any shot at transfer-switch backup. The CO Watchdog sensor adds automatic shutoff protection that many budget inverters still skip.

    Pros:
    • Inverter technology delivers clean power for sensitive electronics
    • Fuel shutoff protects the carburetor during storage
    • Lightweight and easy to carry compared to open-frame models
    • CO Watchdog auto-shutdown for safety
    Cons:
    • Only 2,250 rated watts on gasoline — limited to small loads
    • Propane mode drops output further to 2,000 rated watts

    Best for: Campers, tailgaters, and apartment-adjacent users who need quiet, electronics-safe power for small loads

    Not ideal for: Storm-prep buyers who want to run a refrigerator and furnace simultaneously — the wattage simply isn’t there

    • Fuel Type:Dual Fuel (Gasoline / Propane)
    • Surge Watts:2,800W (both fuels)
    • Power Quality:Inverter — clean power for sensitive electronics
    • Safety:CO Watchdog automatic shutdown
    • Outlets:Two 120V receptacles, one 12V DC, two 5V USB
    • Warranty:3 years
    Our verdict
    “The DF280iX is the pick when quiet, portable, electronics-safe power matters more than raw wattage.”
  3. Westinghouse WGen9500DF 12,500 Watt Dual Fuel Portable Generator

    Westinghouse WGen9500DF 12,500 Watt Dual Fuel Portable Generator

    Best Overall for Whole-Home Backup

    View on Amazon

    The Westinghouse WGen9500DF is the model I’d point most serious backup shoppers toward, because it hits the sweet spot between capacity and usability. With 9,500 running watts on gasoline (8,500 on propane), it handles a transfer-switched home’s core circuits where the WEN DF475T runs out of headroom. The remote key fob start is the standout convenience — no trudging into a garage or out into weather to fire it up, with electric and recoil as backups.

    Its RV-ready 14-50R and transfer-switch-ready L14-30R outlets cover the two most common hookup scenarios without adapters. Compared with the DuroStar DS13000MX, it gives up some peak wattage but adds remote start and a longer warranty plus lifetime technical support. The cost is size: this is a two-person move even with never-flat wheels, and out-of-box assembly is required.

    Pros:
    • 9,500 running watts on gasoline powers multiple major appliances
    • Remote key fob start plus electric and recoil backups
    • RV-ready and transfer-switch-ready outlets out of the box
    • 3-year limited warranty with lifetime technical support
    Cons:
    • Very heavy and bulky — realistically a two-person move
    • Requires some assembly before first use
    • May ship with residual oil or fuel odor from factory testing

    Best for: Suburban homeowners wiring into a transfer switch who want remote start and enough wattage for major appliances

    Not ideal for: Anyone without a dedicated storage spot or a second pair of hands — it’s simply too heavy to shuttle around

    • Fuel Type:Dual Fuel (Gasoline / Propane)
    • Peak Watts (Gasoline):12,500W
    • Running Watts (Gasoline):9,500W
    • Peak Watts (Propane):11,200W
    • Engine:457cc Westinghouse 4-stroke OHV with cast iron sleeve
    • Start Type:Remote key fob, electric push-button, and recoil
    • Tank Capacity:6.6 gallons
    • Run Time:Up to 12 hours
    • Warranty:3-year limited with lifetime support
    Our verdict
    “For whole-home emergency backup with everyday convenience, the WGen9500DF is the most balanced dual fuel generator in this lineup.”
  4. WEN 6,800-Watt Dual Fuel RV-Ready Electric Start Portable Inverter Generator with Fuel Shut Off and CO Watchdog for Electric Vehicle Backup (DF680iX)

    WEN 6,800-Watt Dual Fuel RV-Ready Electric Start Portable Inverter Generator with Fuel Shut Off and CO Watchdog for Electric Vehicle Backup (DF680iX)

    Best for RV Owners and EV Owners

    View on Amazon

    The WEN DF680iX occupies a niche no other model here touches: its bonded-neutral 240V configuration supports low-power Level 2 EV charging, making it a genuine bridge product for electric-vehicle owners worried about grid outages. On top of that, it’s a fully capable RV machine with a dedicated TT-30R receptacle and clean inverter power (under 1.2% THD at full load) at a modest 64 decibels — far quieter than the open-frame WEN DF475T.

    Compared with the smaller WEN DF280iX, this unit nearly doubles the output while keeping the same storage-friendly fuel shutoff and CO Watchdog safety. The catch is runtime: the efficient 2.9-gallon tank yields only 6.1 hours at half load on gasoline, noticeably shorter than larger conventional units, so propane’s 9-hour figure becomes the better long-outage play.

    Pros:
    • Bonded-neutral 240V output enables low-power Level 2 EV charging
    • Clean inverter power safe for laptops, phones, and monitors
    • Dedicated TT-30R RV outlet plus tool-free LPG quick-connector
    • Eco mode and fuel shutoff reduce consumption and maintenance
    Cons:
    • Only 6.1 hours of half-load runtime on gasoline
    • Propane mode drops running output to 4,500 watts
    • Inverter capacity limits it well below whole-home backup needs

    Best for: RV travelers and EV owners who need quiet, electronics-safe inverter power with 240V capability

    Not ideal for: Buyers prioritizing long overnight runtimes on gasoline — the small tank needs frequent refills under sustained loads

    • Fuel Type:Dual Fuel (Gasoline / Propane)
    • Engine:224cc
    • Noise Level:64 dB at quarter load
    • Tank Capacity:2.9 gallons
    • Run Time:6.1 hours half load (gas); 9 hours half load (20-lb LPG)
    • Outlets:L14-30R 120/240V, two 120V 5-20R, TT-30R RV, 12V DC, two USB
    • Warranty:3 years
    Our verdict
    “The DF680iX makes the most sense for RV and EV households that value quiet, clean power over maximum wattage.”
  5. DuroStar DS13000MX 13,000-Watt 500cc Dual Fuel Portable Generator

    DuroStar DS13000MX 13,000-Watt 500cc Dual Fuel Portable Generator

    Best Heavy-Duty Pick for Whole-House Power

    View on Amazon

    When the goal is running essentially everything at once, the DuroStar DS13000MX out-muscles the field with 13,000 watts from a 500cc engine and a 50-amp transfer-switch-ready outlet. It edges past the Westinghouse WGen9500DF on raw output, which is the difference between backing up core circuits and running a large home’s full load — including AC — through a proper switch.

    The all-metal steel frame and reinforced power panel suit it to job sites and harsh conditions where plastic-clad units feel fragile, and CO Alert auto-shutdown brings modern safety to a high-output machine. But this power has a price: it’s the least portable option in this batch, and a 500cc engine on gasoline drinks fuel quickly, so propane’s storability becomes a real strategic advantage rather than a nice extra.

    Pros:
    • 13,000 watts powers an entire home via transfer switch
    • All-metal steel frame built for harsh conditions
    • CO Alert automatic shutdown for safety
    • 50-amp heavy-duty outlet supports high-demand hookups
    Cons:
    • Very large and heavy — portability is limited
    • High fuel consumption on gasoline under heavy loads

    Best for: Owners of large homes or job sites who need maximum simultaneous wattage through a 50-amp transfer switch

    Not ideal for: Anyone who expects to move the generator regularly — it’s realistically a stationary install despite the ‘portable’ label

    • Fuel Type:Dual Fuel (Gasoline / Propane)
    • Wattage:13,000W
    • Engine:500cc
    • Start Type:Push-button electric start with remote
    • Outlets:50-amp heavy-duty transfer-switch-ready outlet
    • Safety:CO Alert carbon monoxide auto-shutdown
    • Construction:All-metal steel frame with reinforced power panel
    • Intended Use:Whole home backup, transfer switch, RV, emergency
    Our verdict
    “The DS13000MX is the choice when whole-house wattage and rugged build matter more than convenience or portability.”
  6. WEN DF360iX 3600-Watt Dual Fuel RV-Ready Portable Inverter Generator with Fuel Shut Off and CO Watchdog

    WEN DF360iX 3600-Watt Dual Fuel RV-Ready Portable Inverter Generator with Fuel Shut Off and CO Watchdog

    Best Lightweight Inverter for RV Trips

    View on Amazon

    The WEN DF360iX earns its spot by being the easiest generator in this lineup to actually pick up and carry. It sits a step above the smaller WEN DF280iX in raw output — 2900 rated watts on gasoline versus 2800 — which is enough headroom to run an RV air conditioner startup without tripping overload, something the 2800-class units struggle with. The TT-30R RV receptacle means no adapter dongles hanging off the panel, and the tool-free propane quick-connector makes switching fuel a thirty-second job at a campsite. Compared with the WEN DF480iX, this model trades 1100 rated watts for a lighter package, and that tradeoff makes sense for campers who move the generator weekly. The one real compromise: propane output drops to 2600 rated watts, which can choke if you stack a microwave on top of an AC unit.

    Pros:
    • Tool-free propane quick-connector for fast fuel switching
    • RV-ready TT-30R outlet with no adapter needed
    • CO Watchdog automatic shutoff for safety while sleeping
    • Lightweight enough for one person to load and move
    Cons:
    • Propane mode drops to 2600 rated watts, limiting concurrent loads
    • No electric start — recoil pull only

    Best for: RV owners and campers who want quiet, clean power they can lift into a truck bed without help

    Not ideal for: Households planning to run multiple large appliances — the rated wattage is too low for a fridge, AC, and water heater together

    • Model:WEN DF360iX
    • Fuel Type:Dual Fuel (Gasoline / Propane)
    • Gasoline Output:3600 surge / 2900 rated watts
    • Propane Output:3500 surge / 2600 rated watts
    • Outlets:2x 120V 5-20R, TT-30R RV, 12V DC, 2x USB
    • Safety Features:CO Watchdog sensor, fuel shut-off
    • Warranty:3 years
    Our verdict
    “If your generator needs to travel with an RV and stay quiet at campgrounds, this is the most sensible watt-to-weight ratio on the list.”
  7. WEN DF1100T 11,000-Watt 120V/240V Dual Fuel Portable Generator with Wheel Kit and Electric Start

    WEN DF1100T 11,000-Watt 120V/240V Dual Fuel Portable Generator with Wheel Kit and Electric Start

    Best High-Wattage Workhorse on a Budget

    View on Amazon

    When the job is keeping a house running through an outage, the WEN DF1100T delivers 8300 running watts on gasoline at a more accessible position than the comparable DuroMax XP13000EH, while still offering the NEMA 14-50R 240V outlet that transfer switches and well pumps demand. The 457cc engine and electric key start mean you are not yanking a cord in freezing weather, and the four GFCI-protected 120V outlets give jobsite crews room to spread out tools. Compared with the WEN DF8000X, this model trades away the CO Watchdog sensor and the longer three-year warranty in exchange for roughly 1800 extra running watts — that is a real safety and support concession, not a trivial one. Propane output falls to 7500 running watts, and at this frame size the wheel kit is a necessity, not a convenience.

    Pros:
    • NEMA 14-50R 240V 50A outlet for transfer switches and high-draw appliances
    • Electric key start with a 457cc engine built for sustained loads
    • Four GFCI outlets for jobsite tool distribution
    • Includes wheel kit, handle, and 47-inch LPG hose out of the box
    Cons:
    • No carbon monoxide shutoff sensor
    • Only a two-year warranty versus three on newer WEN models
    • Heavy and bulky despite wheels — not a one-person lift

    Best for: Homeowners or contractors who need 240V transfer-switch power and maximum running watts without paying for a premium brand name

    Not ideal for: Anyone prioritizing modern safety features — there is no CO shutoff sensor, unlike the DF8000X and Westinghouse units

    • Model:WEN DF1100T
    • Fuel Type:Dual Fuel (Gasoline / Propane)
    • Gasoline Output:11,000 surge / 8,300 running watts
    • Propane Output:9,500 surge / 7,500 running watts
    • Engine:457cc 4-stroke OHV, electric key start
    • Fuel Tank:6.6 gallons, up to 8.5 hours at half load
    • Voltage:120V/240V switchable
    • Warranty:2 years
    Our verdict
    “This is the pick when raw wattage per dollar drives the decision and you can live without the newer CO-safety features.”
  8. WEN Quiet and Lightweight 4800-Watt Dual Fuel RV-Ready Electric Start Portable Inverter Generator with Fuel Shut Off and CO Watchdog (DF480iX)

    WEN Quiet and Lightweight 4800-Watt Dual Fuel RV-Ready Electric Start Portable Inverter Generator with Fuel Shut Off and CO Watchdog (DF480iX)

    Best Inverter for Home Backup and Camping in One

    View on Amazon

    The WEN DF480iX occupies a sweet spot that most generators in this roundup miss: it is quiet and portable enough for campgrounds, yet its 4000 rated watts can carry a refrigerator and a window AC unit during an outage. Where the WEN DF360iX forces a choice between portability and power, this model adds a keyless electric start, wheels, and a telescoping handle, so the extra output does not cost you much in usability. Propane runtime is the standout — up to 20 hours at half load on a 20-pound tank, roughly triple its gasoline endurance, which makes propane the obviously smart fuel choice here. The sub-1.2% THD inverter output is genuinely safe for laptops and TVs rather than merely claimed to be. The compromises are real: propane rated output drops to 3600 watts, and 78.5 pounds is a two-person lift into a truck bed without the wheels.

    Pros:
    • Electric start plus recoil backup at a mid-size inverter weight class
    • Up to 20 hours half-load runtime on a 20-lb propane tank
    • Sub-1.2% THD clean power for sensitive electronics
    • Parallel-capable to double wattage with a second WEN inverter
    Cons:
    • Propane rated output drops to 3600 watts from 4000 on gasoline
    • At 78.5 pounds it is awkward to load without help
    • Small 1.9-gallon gas tank limits gasoline runtime to about 7 hours

    Best for: Buyers who want one generator for both RV trips and emergency home backup, with clean power for electronics

    Not ideal for: Tailgaters or campers who frequently lift the unit solo — the weight defeats the portability advantage of smaller inverters

    • Model:WEN DF480iX
    • Fuel Type:Dual Fuel (Gasoline / Propane)
    • Gasoline Output:4800 surge / 4000 rated watts
    • Propane Output:4320 surge / 3600 rated watts
    • Engine:224cc, 62 dB at quarter load
    • Runtime:7 hrs half load (gas), 20 hrs half load (20-lb LPG)
    • Starting:Keyless electric start with recoil backup
    • Warranty:3 years
    Our verdict
    “This is the single-generator answer for people who refuse to buy separate camping and emergency units.”
  9. WEN 8000-Watt 120V/240V Dual Fuel Portable Generator, Electric Start, 340cc, Transfer-Switch and RV-Ready with CO Watchdog (DF8000X)

    WEN 8000-Watt 120V/240V Dual Fuel Portable Generator, Electric Start, 340cc, Transfer-Switch and RV-Ready with CO Watchdog (DF8000X)

    Best Balance of Whole-Home Power and Safety

    View on Amazon

    The WEN DF8000X is arguably the most rational whole-home backup in this lineup because it fixes the WEN DF1100T’s two biggest gaps — adding the CO Watchdog shutoff sensor and extending the warranty to three years — while still providing 6500 running watts and the transfer-switch-ready L14-30R 240V twist lock. For most houses, 6500 running watts covers a fridge, freezer, furnace blower, sump pump, and lights simultaneously; the extra 1800 watts on the DF1100T mostly matters if you are running a well pump or central AC. The 6.7-gallon tank delivers 10.5 hours at half load, comfortably ahead of the DF1100T’s 8.5, which means fewer midnight refuels during an outage. What you give up: propane mode drops to 5850 running watts, this is a conventional open-frame generator without inverter-clean power, and it is loud enough that campgrounds are off the table.

    Pros:
    • CO Watchdog automatic shutoff for overnight home backup use
    • L14-30R twist lock ready for direct transfer-switch hookup
    • 10.5 hours of half-load runtime on a 6.7-gallon tank
    • Digital data meter showing voltage, frequency, and runtime hours
    Cons:
    • Not inverter-clean power — unsafe for direct sensitive-electronics use
    • Propane output drops to 5850 running watts
    • Heavy open-frame design with no carry solution beyond the wheel kit

    Best for: Suburban homeowners who want a transfer-switch-ready backup with modern CO safety and long runtime between fill-ups

    Not ideal for: Campers and anyone running laptops or TVs directly — no inverter means dirtier power and louder operation

    • Model:WEN DF8000X
    • Fuel Type:Dual Fuel (Gasoline / Propane)
    • Gasoline Output:8000 surge / 6500 rated watts
    • Propane Output:7200 surge / 5850 rated watts
    • Engine:340cc 4-stroke, electric start with recoil backup
    • Fuel Tank:6.7 gallons, up to 10.5 hours at half load
    • Outlets:4x 120V 5-20R, TT-30R, L14-30R 240V, 12V DC
    • Safety Features:CO Watchdog sensor
    • Warranty:3 years
    Our verdict
    “If you want the safest, longest-running WEN for home standby duty rather than maximum watts, this model beats its bigger sibling on the features that matter overnight.”
  10. Westinghouse 13500 Peak Watt Dual Fuel Home Backup Portable Generator, Remote Electric Start, Transfer Switch Ready, Gas and Propane Powered

    Westinghouse 13500 Peak Watt Dual Fuel Home Backup Portable Generator, Remote Electric Start, Transfer Switch Ready, Gas and Propane Powered

    Best Premium Whole-Home Backup

    View on Amazon

    The Westinghouse WGen10500DFc is the most feature-complete home backup in this batch. Its remote key-fob start is something none of the WEN units offer — during a storm, starting a generator from inside the garage is a genuinely practical luxury, not a gimmick. With 10,500 running watts on gasoline and a 9.5-gallon tank stretching runtime to 19 hours, it outlasts the WEN DF1100T by more than double on a single fill, which is the difference between sleeping through the night and getting up to refuel. Both the L14-30R and 14-50R outlets are transfer-switch ready, and the 500cc engine’s cast iron sleeve is built for years of seasonal abuse. The tradeoffs are size and scope: this is a stationary backup, not a portable you reposition weekly, and propane mode gives up 1000 running watts. Compared with the 14500-peak Westinghouse sibling, this model sacrifices a little surge headroom for a smaller, more manageable frame.

    Pros:
    • Remote key-fob start plus electric and recoil backups
    • Up to 19 hours runtime on the 9.5-gallon tank
    • Both L14-30R and 14-50R outlets transfer-switch ready with rubber covers
    • 3-year warranty with lifetime technical support and nationwide service network
    Cons:
    • Very large and heavy — effectively a fixed installation despite never-flat wheels
    • Propane mode drops to 9500 running watts from 10,500
    • Requires minimal assembly and a battery charge before first use

    Best for: Homeowners who want near-standby-generator capability in a portable package, with remote start and multi-day runtime

    Not ideal for: Campers, tailgaters, or anyone without storage space — this unit is heavy, loud, and clearly built to live beside a transfer switch

    • Model:Westinghouse WGen10500DFc
    • Fuel Type:Dual Fuel (Gasoline / Propane)
    • Gasoline Output:13,500 peak / 10,500 running watts
    • Propane Output:12,500 peak / 9,500 running watts
    • Engine:500cc 4-stroke OHV with cast iron sleeve
    • Starting:Remote key fob, electric, and recoil
    • Fuel Tank:9.5 gallons, up to 19 hours runtime
    • Outlets:2x GFCI 120V 5-20R, L14-30R 30A, 14-50R 50A
    • Warranty:3 years limited, lifetime tech support
    Our verdict
    “For buyers treating this as a semi-permanent home backup rather than a portable tool, the remote start and 19-hour runtime justify choosing it over the WEN workhorses.”
  11. Westinghouse WGen5300DFcv 6500 Peak Watt Dual Fuel Portable Generator with CO Sensor

    Westinghouse WGen5300DFcv 6500 Peak Watt Dual Fuel Portable Generator with CO Sensor

    Best Mid-Size Value

    View on Amazon

    For buyers who need real home backup capability without paying for excess wattage, this model hits a sweet spot. It produces 5,300 running watts on gasoline — enough for a fridge, furnace fan, lights, and a few small appliances — while keeping the price and physical footprint closer to the compact WEN DF475T than to the big-home units like the Westinghouse 12500. What makes this pick stand out is its 14.5-hour runtime from a 4.7-gallon tank, which outlasts many larger generators and means fewer 2 a.m. refueling trips during an outage. The tradeoff is honest: propane output drops to 4,800 running watts, so buyers relying on a propane hookup should size their load accordingly. Compared with the DuroMax XP13000EH, it obviously can’t run a whole house, but for essential-circuit backup through a transfer switch, it covers the basics with a strong safety suite including a CO sensor.

    Pros:
    • Up to 14.5 hours of runtime on a single tank, longer than many larger units
    • RV-ready TT-30R and transfer-switch-ready L14-30R outlets cover both travel and home backup
    • CO sensor with automatic shutdown adds a real safety layer for garage-adjacent use
    • Ships with oil, propane hose, tool kit, and wheel kit so it’s running nearly out of the box
    Cons:
    • Propane output drops to 4,800 running watts, which limits full-fuel-flexibility sizing
    • Arrives requiring minor assembly and may carry residual oil odor from factory testing

    Best for: Homeowners who want to power essential circuits through a transfer switch without overspending on whole-house wattage

    Not ideal for: Households running central air conditioning or well pumps — the 5,300 running watts won’t cover a heavy startup load

    • Running Watts (Gasoline):5,300 W
    • Peak Watts (Gasoline):6,500 W
    • Running Watts (Propane):4,800 W
    • Engine:274cc 4-Stroke OHV with cast iron sleeve
    • Fuel Tank:4.7 gallons
    • Runtime:Up to 14.5 hours
    • Outlets:5-20R duplex, TT-30R RV, L14-30R 30A
    • Safety:CO sensor auto shutdown, low oil shutdown
    • Warranty:3-year limited
    Our verdict
    “A smart middle-ground pick for essential-circuit home backup where long runtime matters more than raw wattage.”
  12. DuroMax XP13000EH 13,000-Watt Dual Fuel Portable Generator

    DuroMax XP13000EH 13,000-Watt Dual Fuel Portable Generator

    Best Whole-Home Powerhouse

    View on Amazon

    When the goal shifts from essentials to running nearly everything in the house at once, this is where the XP13000EH earns its place. Its 13,000-watt output sits in the same class as the DuroStar DS13000MX, but DuroMax differentiates itself with a push-button electric start and a front-facing fuel selector that lets you switch between gasoline and propane in seconds — a genuine convenience mid-outage when one fuel runs dry. The all-metal construction and copper windings point to durability under years of heavy use, something the lighter WEN DF8000X can’t match at its lower output tier. The tradeoffs are size and noise: this is a large, heavy machine built to live in a garage or shed and roll out on no-flat tires, not something you toss in an RV bay. Buyers choosing between this and the Westinghouse 12500 are really choosing between raw capacity and a more refined feature set.

    Pros:
    • 13,000 watts covers whole-home loads including large appliances
    • Front-facing fuel selector switches between gas and propane in seconds
    • All-metal frame and 100% copper windings built for years of heavy use
    • Transfer-switch-ready 50A outlet plus a wide outlet variety including RV options
    Cons:
    • Large and heavy enough that moving it solo is difficult despite no-flat tires
    • Conventional (non-inverter) output is less ideal for sensitive electronics

    Best for: Homeowners who want to back up most of a large house during extended outages and have space to store a big unit

    Not ideal for: Campers or anyone without help moving it — the size and weight make it impractical for frequent repositioning

    • Peak Watts:13,000 W
    • Fuel Types:Gasoline and propane
    • Start Type:Push-button electric start
    • Frame:Heavy-duty all-metal with power panel
    • Windings:100% copper
    • Key Outlet:Transfer-switch-ready 50A
    • Tires:No-flat, all-terrain
    Our verdict
    “The pick when you genuinely need whole-house coverage from a portable dual fuel platform.”
  13. Westinghouse 12500 Peak Watt Dual Fuel Home Backup Portable Generator

    Westinghouse 12500 Peak Watt Dual Fuel Home Backup Portable Generator

    Best for Serious Home Backup

    View on Amazon

    This model occupies the practical upper tier of home backup: 9,500 running watts on gasoline and 8,500 on propane, with a 50A RV-ready receptacle that makes connecting to a transfer switch or RV shore-style inlet straightforward. Compared with the DuroMax XP13000EH, it gives up some peak capacity but gains a remote key fob start — meaning you can fire it up from inside the house during a storm rather than trudging out in the rain to a recoil handle. Against its own sibling, the WGen5300DFcv, the jump in wattage is what enables running a well pump or window AC units alongside basics. The 457cc engine and 6.6-gallon tank deliver up to 12 hours of runtime, shorter per tank than the smaller Westinghouse but reasonable for the output. The honest cost is weight and bulk — this is a two-person move on anything but flat pavement.

    Pros:
    • Remote key fob start plus electric and recoil backup for reliable starts in bad weather
    • 50A 14-50R outlet handles transfer switch or RV connections at full capacity
    • CO sensor and low oil automatic shutdown protect against common misuse
    • Runs 8,500 watts even on propane, preserving most capability on either fuel
    Cons:
    • Heavy and bulky; difficult for one person to move over uneven ground
    • Requires minor assembly and may arrive with factory-test oil residue
    • 12-hour runtime trails the smaller WGen5300DFcv per tank

    Best for: Suburban homeowners pairing a generator with a transfer switch who want remote start convenience and heavy-duty output

    Not ideal for: Anyone planning to load it in and out of a truck bed regularly — the weight makes it a fixed-position machine

    • Running Watts (Gasoline):9,500 W
    • Peak Watts (Gasoline):12,500 W
    • Running Watts (Propane):8,500 W
    • Engine:457cc 4-Stroke OHV with cast iron sleeve
    • Fuel Tank:6.6 gallons
    • Runtime:Up to 12 hours
    • Start Types:Remote key fob, electric, recoil
    • Safety:CO sensor, low oil shutdown
    • Warranty:3-year limited
    Our verdict
    “A strong choice for transfer-switch home backup where remote start and high propane output matter most.”
  14. PowerSmart 3800 Watt Dual Fuel Inverter Generator

    PowerSmart 3800 Watt Dual Fuel Inverter Generator

    Best Quiet Portable Pick

    View on Amazon

    Most dual fuel generators in this roundup are conventional open-frame machines built for wattage, not manners. This one inverts the priority: at 59 dBA in Eco Mode, it’s quiet enough for campsites and tailgates where the WEN DF475T would draw complaints. The inverter design also means clean power safe for laptops and phones, and the built-in USB ports let you skip a separate charger. Its cleverest trick is propane runtime — up to 24 hours on a standard 20-lb tank, which dramatically outlasts its own 1.3-gallon gasoline tank (about 8 hours at quarter load). Compared with the WEN DF280iX, you get noticeably more starting wattage for home-essentials duty, though both share the same clean-power advantage over the Westinghouse WGen5300DFcv. The tradeoff is capacity: 3,300 running watts on gas and 3,100 on propane means one fridge and a few lights, not a furnace plus a pump. UL2201 certification for CO safety is a differentiator many competitors lack.

    Pros:
    • 59 dBA operation in Eco Mode, far quieter than open-frame dual fuel models
    • Up to 24 hours of runtime on a 20-lb propane tank
    • Inverter output plus USB ports makes it genuinely laptop- and phone-friendly
    • ANSI/UL2201 and PGMA G300 certified CO protection
    Cons:
    • Tiny 1.3-gallon gas tank caps gasoline runtime around 8 hours at light load
    • Propane running watts drop to 3,100, limiting simultaneous appliance use

    Best for: Campers, tailgaters, and apartment-adjacent backup users who need quiet, electronics-safe power with long propane runtime

    Not ideal for: Homeowners with a furnace, well pump, or AC to run — the running wattage is too limited for multi-appliance backup

    • Starting Watts (Gasoline):3,800 W
    • Running Watts (Gasoline):3,300 W
    • Running Watts (Propane):3,100 W
    • Noise Level:59 dBA at 25% load (Eco Mode)
    • Fuel Tank:1.3 gallons
    • Runtime:8 hrs (gas, 25% load); up to 24 hrs on 20-lb propane
    • Outlets:L5-30R, 5-20R duplex, 12V DC, dual USB
    • Certifications:ANSI/PGMA G300, ANSI/UL2201, EPA
    • Warranty:2-year limited with lifetime support
    Our verdict
    “The quiet, clean-power choice for recreation and light backup — as long as your load stays modest.”
  15. Westinghouse 14500 Peak Watt Dual Fuel Home Backup Portable Generator

    Westinghouse 14500 Peak Watt Dual Fuel Home Backup Portable Generator

    Best Maximum Capacity

    View on Amazon

    This is the ceiling of the lineup: 11,500 running watts on gasoline, 10,500 on propane, driven by a 550cc engine that out-muscles both the Westinghouse 12500 and the DuroMax XP13000EH. The headline spec for serious outage prep, though, is the 9.5-gallon tank delivering up to 19 hours of runtime — meaning overnight outages pass without a refueling stop, something none of the smaller units here can promise at this load level. It also adds low THD output, making it friendlier to electronics than the DuroMax, which lacks inverter-grade power quality. The tradeoffs mirror every machine in this class, amplified: it’s the heaviest, least portable option in the roundup, and propane runtimes on a standard 20-lb tank drop to around 7 hours, so propane users will want larger tanks on hand. For buyers sizing a generator once and never wanting to wish for more, this is the pick.

    Pros:
    • 11,500 running watts powers a large home’s major loads simultaneously
    • Up to 19 hours of runtime from the 9.5-gallon tank for overnight coverage
    • Low THD output is safer for sensitive electronics than typical open-frame units
    • Copper windings and cast iron sleeve point to long service life under heavy use
    Cons:
    • Largest and heaviest machine in the roundup; portability is limited
    • Propane mode yields lower wattage and only about 7 hours on a 20-lb tank

    Best for: Buyers in outage-prone regions who want maximum wattage and multi-day runtime capacity in one purchase

    Not ideal for: Anyone with limited storage space or plans to move the generator often — size and weight rule out casual portability

    • Peak Watts (Gasoline):14,500 W
    • Running Watts (Gasoline):11,500 W
    • Running Watts (Propane):10,500 W
    • Engine:550cc 4-Stroke OHV Westinghouse
    • Fuel Tank:9.5 gallons
    • Runtime (Gasoline):Up to 19 hours
    • Runtime (Propane):Up to 7 hours on 20-lb tank
    • Start Type:Remote electric start
    • Power Quality:Low THD output
    Our verdict
    “The buy-once, maximum-capacity option for whole-home backup where runtime and wattage both matter.”

How We Picked

I evaluated each generator across five criteria that map directly to how dual fuel units are actually used. Power output and fuel flexibility came first: I compared running and peak wattage on both gasoline and propane, since the propane number is what most buyers will actually rely on during an extended outage. Safety features ranked models with carbon monoxide auto-shutoff (CO Watchdog or equivalent sensors) above those without, because closed garages and poorly ventilated setups remain the leading cause of generator-related incidents. Usability covered electric start, remote start, fuel shutoff for storage, and the presence of a transfer-switch-ready 240V outlet for whole-home wiring.

From there, I weighed portability and noise — wheel kits, weight, and whether the unit is an inverter with clean sine wave output for electronics — and value per watt, which explains why mid-size models like the Westinghouse WGen9500DF and WEN DF8000X rank higher than headline-grabbing 13,000-watt units for most buyers. The ranking favors units that match realistic household loads over maximum spec-sheet numbers, and it penalizes models that ask you to give up safety tech or electric start to hit a price point.

Factors to Consider When Choosing Dual Fuel Generators

Choosing between dual fuel generators comes down to matching the machine to your actual load, your storage situation, and how you plan to fuel it during an outage. These are the factors that separated the top picks from the rest — and the mistakes that cost buyers the most regret.

Size to Your Propane Numbers, Not the Headline Wattage

The wattage printed largest on the box is almost always the gasoline peak figure, and every dual fuel generator in this class loses roughly 10 percent of its output when running on propane. That gap matters because propane is what most people store for emergencies — gasoline degrades within months and is hard to buy during a widespread outage, while a 20-pound propane tank can sit ready for years. Before picking a model, add up the starting wattage of your must-run appliances (refrigerator, furnace blower, sump pump, and either a well pump or window AC unit) and add 20 percent headroom. If that total is 7,000 watts, a “9,500-watt” generator is really a 7,600-watt generator once you account for the propane derate and altitude losses. The most common buying mistake in this category is sizing to the gasoline number and discovering mid-outage that the propane tank can’t carry the full load.

Inverter vs. Open Frame: Clean Power or Raw Value

Inverter generators like the WEN DF280iX and DF480iX produce clean sine wave power that’s safe for laptops, TVs, and modern furnaces with electronic control boards, and they run dramatically quieter than open-frame units. Open-frame conventional generators — the DuroMax, DuroStar, and larger Westinghouse models — deliver far more wattage per dollar and handle heavy motor loads like well pumps better, but their power is dirtier and their noise levels are unsuitable for close neighbors or campgrounds. A middle path exists in models like the WEN DF680iX and DF8000X, which offer inverter or partial-inverter designs at higher output. If your plan is purely home backup with motor-driven appliances, open frame is the value play. If you’ll ever run sensitive electronics or use the generator recreationally, an inverter pays for itself the first time it doesn’t fry a control board.

Whole-Home Backup Means Transfer Switch Readiness

A 240V twist-lock outlet rated for transfer switch connection is what separates true home backup units from big portable generators. Without it, you’re limited to running extension cords through a window — which is inconvenient at best and a fire hazard at worst. Every Westinghouse model from the WGen9500DF upward and both 13,000-watt DuroMax/DuroStar units include proper transfer switch connectivity, and hiring an electrician to install a manual transfer switch typically costs a few hundred dollars. What buyers often overlook is the interlock kit alternative: many electrical panels accept an interlock breaker that provides legal whole-panel backfeed capability for less than a transfer switch. Either way, plan this installation before storm season, not during it — electricians book up fast when outages are forecast.

Electric and Remote Start Are Worth Paying For

Recoil-start generators save money, but pulling a starter cord on a cold 500cc engine in the rain at 6 a.m. is where backup plans fall apart. Every model ranked highly in this roundup includes electric start, and the Westinghouse 13,500 and 14,500-watt models add remote start fobs that let you fire up the generator from inside the house — a genuine quality-of-life feature when weather is bad. The hidden cost of electric start is battery maintenance: the starter battery needs a trickle charger or monthly top-up, and a dead battery silently converts your electric start unit back into a recoil unit. Look for models with included battery tender cables (Westinghouse includes them on most units). If you’re choosing between a larger recoil unit and a slightly smaller electric start model at the same price, take the electric start.

Carbon Monoxide Safety Tech Should Be Non-Negotiable

Every year, deaths from generators come overwhelmingly from carbon monoxide poisoning, not fire or electrocution, and manufacturers have responded with auto-shutoff sensors. WEN’s CO Watchdog, Westinghouse’s CO sensor, and equivalent systems kill the engine when CO levels near the unit rise dangerously — a feature that protects against the most common misuse, which is running a generator too close to the house or under a covered porch. In this lineup, the older DuroStar DS13000MX is the model most worth scrutinizing on this point, so verify the current revision includes a CO sensor before buying. My position is simple: treat a CO shutoff sensor as a hard requirement, the same way you’d treat brakes on a car. No wattage savings justifies skipping it.

Weight, Wheels, and the Reality of Moving 200+ Pounds

The 13,000-watt class generators all weigh north of 200 pounds, and even with wheel kits, they’re effectively stationary once positioned. That’s fine if the unit lives on a pad beside your electrical panel, but it’s a real limitation if you plan to move it between home backup and job sites or RV trips. Mid-size units like the WEN DF475T and Westinghouse WGen5300DFcv strike a workable balance at 100 to 150 pounds with decent wheel kits. True inverter models under 4,000 watts can be lifted by one or two people and transported in a car trunk. Before buying, honestly answer where the generator will live and who will move it — the best generator is one you can actually deploy when the power goes out, not one that requires two neighbors and a ramp.

Frequently Asked Questions

Do dual fuel generators lose power when running on propane?

Yes — virtually every dual fuel generator produces about 10 percent less wattage on propane than on gasoline, and this applies across the entire lineup here. A generator rated at 9,500 running watts on gasoline will typically deliver around 8,600 on propane. The tradeoff is worth it for many buyers because propane stores indefinitely, burns cleaner (meaning less carbon buildup and oil contamination), and is often the only fuel available during a widespread outage. The practical approach is to size your generator so the propane rating covers your essential loads, then treat gasoline output as bonus headroom. Also factor in altitude: above 3,000 feet elevation, both fuel types lose roughly 3 percent output per 1,000 feet.

Can a dual fuel generator actually run my whole house?

The 13,000-watt models in this roundup — the DuroMax XP13000EH and DuroStar DS13000MX — can run most of a typical house including a 3-ton central AC unit, but “whole home” has limits. Electric water heaters, electric dryers, and electric ranges each draw 4,000 to 5,500 watts, and stacking them with AC will trip breakers even on the big units. The realistic calculation is a load sheet: list each appliance’s starting and running watts, and see what fits under roughly 10,500 running watts (the propane derated figure for a 13,000-watt unit). Most families find they can run everything essential and simply defer high-draw appliances. If your home is all-electric with no gas appliances, consider load management or a standby generator instead of stretching a portable to cover everything.

Is an inverter generator worth the extra cost for home backup?

It depends on what you’re powering. If your essential loads are motor-driven — fridge, furnace blower, sump pump — a conventional open-frame generator handles them fine and costs far less per watt. Inverters earn their premium when sensitive electronics are in the mix: modern furnaces, TVs, laptops, and anything with a circuit board can be damaged by the dirty power conventional generators produce. Inverters also run at 52 to 65 decibels versus 70 to 80-plus for open frames, which matters if you have close neighbors or the unit sits near living spaces. The compromise pick is a high-output inverter like the WEN DF680iX, which bridges the gap but still can’t match the dollar-per-watt value of an open-frame Westinghouse or DuroMax.

How much propane should I store for an extended outage?

At half load, a large generator consumes roughly 1 to 1.5 gallons of propane per hour, meaning a 20-pound tank (about 4.7 gallons) lasts only 3 to 5 hours. That surprises most buyers and is the single biggest logistical shock of generator ownership. For a multi-day outage on a large unit, you’d want a 100-pound tank (roughly 23 gallons, giving 15 to 20 hours) or a permanent 250-gallon propane installation with a proper regulator and connection. Mid-size and inverter units sip far less — a 3,600-watt inverter at quarter load can run 8 to 10 hours on a 20-pound tank. Whatever you store, keep a spare regulator and the correct connectors on hand, because tank fittings vary and hardware stores sell out during outages.

Can I connect a dual fuel generator to my house without a transfer switch?

Not safely, and not legally in most jurisdictions. Backfeeding a dryer or range outlet is a life-threatening hazard for utility workers and a fire risk in your home, and it violates electrical code everywhere in North America. The two compliant options are a manual transfer switch (installed by an electrician, typically a few hundred dollars plus the switch) or an interlock kit on a compatible electrical panel, which costs less but requires your panel to accept one. Many generators in this lineup, including the Westinghouse home backup models and both 13,000-watt units, include the 240V twist-lock outlet you’ll need for either approach. Until that wiring is in place, your fallback is heavy-duty extension cords run through a door or window, which works but limits you to plug-in appliances only.

Conclusion

The right dual fuel generator depends almost entirely on what you’re powering. For best overall, the Westinghouse WGen9500DF covers essential household circuits on either fuel, includes electric start and transfer switch readiness, and avoids the weight and fuel consumption penalties of the 13,000-watt class. For best value, the WEN DF475T delivers dual fuel flexibility, electric start, and a wheel kit at the accessible end of the lineup — a smarter starting point than stretching for more wattage than you need. For best premium whole-home coverage, the DuroMax XP13000EH and Westinghouse 14,500-watt remote start model are the picks; the DuroMax wins on raw value per watt, while the Westinghouse wins on convenience with its remote start fob.

For beginners and casual users, the Westinghouse WGen5300DFcv offers a manageable size, CO sensor, and enough output for a fridge, some lights, and a window AC without overwhelming the owner. For RV owners and campers, the WEN DF280iX or DF360iX inverters are the clear choices — quiet, light, and safe for the electronics you actually travel with — while the WEN DF680iX suits EV owners and RVers who need serious inverter output. Whatever you pick, size to your propane numbers, verify the CO shutoff, and get your transfer switch wiring done before you need it.
