For most households seeking dual fuel home generators, I’d start with the Westinghouse WGen11500DFc for its combination of substantial backup capacity, remote electric start, and gas-or-propane flexibility. The DuroMax XP13000EH and DuroStar DS13000MX are stronger fits for buyers prioritizing higher-output home backup, while the WEN DF360iX suits smaller loads and quieter, more portable use. The main tradeoff is straightforward: larger open-frame generators can support more appliances, but they take more space and need careful placement; inverter models are easier to move and run more quietly, but provide less output. Fuel availability, transfer-switch compatibility, and safe outdoor operation matter just as much as wattage. Read on for the full breakdown and help matching a generator to your home’s needs.

Key Takeaways
- The WGen11500DFc is the strongest all-around fit in this lineup for buyers who want substantial backup output, two fuel choices, and remote electric start without moving to a 13,000-watt-class model.
- The DuroMax XP13000EH, XP13000HX, and DuroStar DS13000MX form the high-output group; choose among them by checking the exact features and connection needs, not peak wattage alone.
- Inverter models serve a different purpose from large open-frame units: the PowerSmart 3800 and WEN DF360iX favor lower-noise, more portable power for modest loads rather than whole-home ambitions.
- Westinghouse offers the broadest spread of sizes here, from the 6600-watt model through the WGen10500DFc and WGen11500DFc, so buyers can avoid paying in size and capacity for output they do not need.
- Dual fuel adds useful flexibility, not extra generator capacity: propane can help with fuel storage, but buyers should verify output on each fuel and plan for a safe outdoor location and compatible transfer equipment.

More Details on Our Top Picks
Westinghouse WGen11500DFc Dual Fuel Portable Generator with Remote Electric Start
The WGen11500DFc is my strongest all-around choice here for households that want substantial backup output without giving up fuel flexibility. Its 11,500 running watts and 240-volt, 50A outlet give it more room for multiple household loads than the WEN DF8000X, while gasoline and propane let owners adapt to whichever fuel is available. The listed 19-hour runtime at 25% load can reduce refueling interruptions when demand is modest, and remote electric start is useful when the unit is staged outside during poor weather.
It also has less than 5% THD, a CO sensor, and low-oil shutdown. The tradeoff is scale: this is a large generator, not a convenient grab-and-go unit, and a transfer switch and related equipment are sold separately. Choose the tri-fuel Westinghouse WGen11500TFc instead if natural-gas operation matters more than keeping the setup strictly dual-fuel.
Pros:- 11,500 running watts provide substantial capacity for home backup loads.
- Gasoline and propane fuel options offer flexibility during outages.
- Remote electric start reduces the effort of starting the generator outdoors.
- Less than 5% THD, a CO sensor, and low-oil shutdown add useful power-quality and safety features.
Cons:- Large output and a 9.5-gallon tank make storage and movement difficult.
- Transfer switch and associated connection equipment are sold separately.
- It does not offer natural-gas operation like the WGen11500TFc.
Best for: Homeowners seeking high-output gasoline-or-propane backup with 240-volt and 50A connection options for a properly configured home setup.
Not ideal for: Apartment residents, buyers needing a lightweight generator, or households that want natural-gas operation or an included transfer switch.
- Peak wattage:14,500 watts
- Running wattage:11,500 watts
- Fuel types:Gasoline and propane
- Engine:550cc 4-stroke OHV

Our verdict“Choose the WGen11500DFc for high-capacity dual-fuel home backup if you have room to store it and will arrange the transfer equipment separately.”
PowerSmart 3800-Watt Dual-Fuel Inverter Generator
The PowerSmart 3800-Watt fills a different role from the large home-backup machines in this group: it is a compact inverter for selected essentials, not a whole-home substitute. At 50.7 pounds, it is far easier to handle than the WEN DF8000X, and its 59 dBA rating at 25% load in Eco Mode suits buyers who value quieter operation. Gasoline delivers 3,300 running watts; propane delivers 3,100, enough for a limited set of appliances and electronics but far below the Westinghouse WGen11500DFc’s capacity.
Its CO, overload, short-circuit, and low-oil protections and mix of AC, DC, and USB outlets make it versatile for small backup needs. The small 1.3-gallon gasoline tank limits refueling intervals, while the listed gasoline runtime is inconsistent across the supplied product information. I would not choose it for 240-volt home circuits or large simultaneous loads.
Pros:- At 50.7 pounds, it is more manageable than the larger WEN DF8000X and high-output Westinghouse models.
- Gasoline and propane operation provide fuel choice for smaller backup needs.
- 59 dBA at 25% load in Eco Mode is suited to noise-conscious use.
- CO, overload, short-circuit, and low-oil protections accompany varied AC, DC, and USB outlets.
Cons:- Its 3,100-watt propane running output is limited for multiple high-demand household appliances.
- The 1.3-gallon gasoline tank is small, and supplied gasoline-runtime information conflicts.
- 120-volt output does not provide the 240-volt connection available on the larger home-backup models.
Best for: Buyers who need a portable, quieter dual-fuel inverter for a few essential 120-volt appliances, electronics, or recreational use.
Not ideal for: Households seeking whole-home backup, 240-volt service, or long gasoline run intervals without frequent refueling.
- Starting wattage:3,800 watts gasoline; 3,500 watts propane
- Running wattage:3,300 watts gasoline; 3,100 watts propane
- Fuel types:Gasoline and propane
- Engine:149cc 4-stroke
- Noise level:59 dBA at 25% load in Eco Mode
- Gas tank:1.3 gallons
- Propane runtime:Up to 24 hours with a standard 20-pound tank
- Voltage:120 volts
- Weight:50.7 pounds
Our verdict“Pick the PowerSmart for portable, quieter essential-load backup, but choose a larger 240-volt generator for household circuits or heavier demand.”
WEN DF8000X Dual-Fuel Portable Generator, 8,000-Watt, Electric Start
The WEN DF8000X lands between the compact PowerSmart inverter and the high-output Westinghouse WGen11500DFc. Its 6,500 running watts on gasoline give it more capacity for a set of household essentials than the PowerSmart, while its 120V/240V output and transfer-switch-ready outlet suit a home connection plan. Electric start handles routine starting, and recoil backup gives the owner another way to start it if needed. A wheel kit is included, a practical advantage over treating a generator this size as a hand-carried unit.
The 6.7-gallon tank is listed for up to 10.5 hours at half load, but that is shorter than the Westinghouse WGen11500DFc’s stated low-load runtime. Propane output also falls to 5,850 running watts, so available capacity changes with fuel choice. It remains a substantial machine, and its wheel kit helps with movement rather than making it lightweight. The CO shutdown sensor is a useful safety feature, not a replacement for safe outdoor placement.
Pros:- 6,500 gasoline running watts offer a middle ground between compact inverters and larger home generators.
- 120V/240V output and a transfer-switch-ready outlet support a home backup connection plan.
- Electric start is backed by recoil starting.
- Wheel kit and CO shutdown sensor are included.
Cons:- Propane running output drops to 5,850 watts.
- The generator is large, so the wheel kit does not make it easy to lift or transport.
- Its stated 10.5-hour runtime is at half load, shorter than the WGen11500DFc’s listed runtime at 25% load.
Best for: Homeowners who want 120V/240V backup for a moderate set of loads, plus electric start, recoil backup, and wheels for repositioning.
Not ideal for: Buyers needing the highest output, a compact portable unit, or equal running capacity on propane and gasoline.
- Starting wattage:8,000 watts gasoline; 7,200 watts propane
- Running wattage:6,500 watts gasoline; 5,850 watts propane
- Fuel types:Gasoline and propane
- Engine:340cc 4-stroke
- Voltage:120V/240V
- Starting system:Electric start with recoil backup
- Gas tank:6.7 gallons
- Runtime:Up to 10.5 hours at half load
- Outlets:Four 120V 20A; one 120V 30A RV; one 120V/240V 30A transfer-switch-ready; one 12V DC
Our verdict“Choose the WEN DF8000X for mid-range 240-volt backup with wheels and dual starting methods, but step up to the WGen11500DFc for greater capacity.”
Westinghouse 14500 Peak Watt Tri-Fuel Home Backup Portable Generator with Remote Electric Start and Transfer Switch Ready
The WGen11500TFc is the choice here for buyers who want the option to run on natural gas as well as gasoline or propane. That third fuel can simplify outage planning for homes with a suitable natural-gas connection, while the listed 11,500 running watts put its gasoline output on par with the dual-fuel WGen11500DFc. Its remote and push-button starting, low-oil shutdown, and CO sensor make it a well-equipped high-output backup unit. Less than 5% THD is also a useful specification for households powering sensitive electronics.
The main distinction from the WGen11500DFc is fuel access, not greater listed running wattage: buyers who do not need natural gas may prefer the simpler dual-fuel alternative. This is still a large generator, and a transfer switch is sold separately despite the transfer-switch-ready description. I would choose it for fuel flexibility, not for portability or an included home-connection package.
Pros:- Gasoline, propane, and natural-gas compatibility expands fuel options beyond the dual-fuel WGen11500DFc.
- 11,500 running watts provide substantial listed gasoline output for home backup.
- Remote electric start and push-button starting simplify operation.
- Less than 5% THD, CO sensing, and automatic low-oil shutdown are specified.
Cons:- Natural-gas capability offers little benefit to buyers without a suitable gas connection.
- Its large, heavy format limits portability.
- Transfer switch and related equipment are sold separately.
Best for: Homeowners with access to natural gas who want the option to switch among three fuels during extended outages.
Not ideal for: Buyers who only need gasoline and propane, have limited storage space, or expect a transfer switch to be included.
- Peak wattage:14,500 watts
- Running wattage:11,500 watts
- Fuel types:Gasoline, propane, and natural gas
- Engine displacement:550cc
- Fuel tank:9.5 gallons
- Runtime:Up to 19 hours at 25% load
- Voltage and frequency:240V, 60Hz
- Total harmonic distortion:Less than 5%
- Material:Steel and aluminum
Our verdict“Choose the WGen11500TFc over the WGen11500DFc when natural-gas access is a meaningful part of your outage plan.”
DuroStar DS13000MX 13,000-Watt Dual Fuel Portable Generator – Gas & Propane, Remote Electric Start, Whole Home Backup, Transfer Switch Ready, RV/Emergency
The DuroStar DS13000MX is a high-output gasoline-and-propane option for buyers who want heavy-duty construction and remote starting. Its 10,500 running watts are close to the WGen11500DFc’s 11,500, so it can serve a similar broad home-backup role while giving up some listed running capacity. The 8.3-gallon tank and stated 17-hour runtime at 50% load provide a useful reference for planning, although load and fuel choice affect actual run time. A 50-amp transfer-switch-ready outlet supports a home connection setup, but the transfer switch itself is not listed as included.
Compared with the tri-fuel WGen11500TFc, the DuroStar sticks to two fuels and has lower stated running wattage; its appeal is the all-metal construction and straightforward dual-fuel format. The tradeoff is a large, heavy machine that can be difficult to move, plus potentially high fuel use under heavy loads. Buyers should match their expected demand to its output rather than assume peak wattage is continuous capacity.
Pros:- 10,500 running watts provide substantial backup capacity, though below the WGen11500DFc’s 11,500 watts.
- Gasoline and propane operation allow a choice of fuel.
- Remote push-button electric start and CO sensor are included.
- All-metal construction and a 50A transfer-switch-ready outlet suit a fixed home backup setup.
Cons:- Its large size and weight make relocation difficult.
- The 8.3-gallon tank can require frequent refueling under heavy demand.
- It lacks the natural-gas option of the Westinghouse WGen11500TFc.
Best for: Homeowners seeking a rugged, high-output gasoline-or-propane generator with remote start and a 50A transfer-switch-ready outlet.
Not ideal for: Buyers who need natural-gas operation, easy one-person portability, or the highest running wattage among the listed high-output options.
- Peak wattage:13,000 watts
- Running wattage:10,500 watts
- Fuel types:Gasoline and propane
- Engine displacement:500cc
- Fuel tank:8.3 gallons
- Runtime:17 hours at 50% load
- Voltage and frequency:240V, 60Hz
- Starting current:43.75A
- Construction:Metal
Our verdict“Pick the DS13000MX for rugged dual-fuel backup with remote start, but choose a higher-running-watt model if your planned loads need more capacity.”
DuroMax XP13000EH 13,000-Watt Dual-Fuel Portable Generator
For buyers who want substantial backup capacity from a dual-fuel unit, the DuroMax XP13000EH pairs 10,500 running watts with a 50-amp transfer-switch-ready outlet. That gives it more running output than the Westinghouse WGen9500DFc, which may matter when several large household loads need power at once. Gasoline or propane operation adds flexibility, while electric start makes routine startup simpler than relying on recoil alone. Its 234-pound weight is a real constraint: this is portable in the wheeled-generator sense, not something to move easily by hand. The listed 3-hour runtime also trails the WGen9500DFc’s stated up-to-12-hour run, so buyers should verify the conditions behind runtime claims and plan fuel accordingly. I’d choose it for output, not long unattended stretches.
Pros:- 10,500 running watts provide substantial capacity for household backup loads.
- Runs on gasoline or propane, giving owners a choice of available fuel.
- Electric start and a transfer-switch-ready 50-amp outlet suit home backup setups.
- All-metal frame, copper windings, and no-flat tires support demanding portable use.
Cons:- At 234 pounds, it is difficult to reposition without its wheels and a clear path.
- Listed runtime is only 3 hours, shorter than the WGen9500DFc’s stated maximum.
- High output does not remove the need to manage fuel supply during extended outages.
Best for: Homeowners seeking high running output and a 50-amp connection for transfer-switch-based backup, with space to store a heavy generator.
Not ideal for: Buyers who need long operation between refueling or must frequently lift and move the generator; its listed runtime is 3 hours and it weighs 234 pounds.
- Fuel type:Gasoline or propane
- Engine:500cc, 4-stroke OHV
- Starting wattage:13,000 watts
- Running wattage:10,500 watts
- Voltage:240 volts
- Runtime:3 hours (listed)
- Weight:234 pounds
- Features:Electric start, CO sensor, hour meter, low-oil shutdown, foldable handle
Our verdict“Choose the XP13000EH when high running output and a 50-amp connection matter more than light weight or long listed runtime.”
Westinghouse WGen9500DFc Dual-Fuel Portable Generator with CO Sensor
The Westinghouse WGen9500DFc makes a strong case for buyers who value straightforward startup and useful run time over maximum output. Its remote, electric, and recoil starting options let an owner start it from a distance or fall back to a manual method, while the 6.6-gallon tank is rated for up to 12 hours. That’s a more practical listed endurance figure than the DuroMax XP13000EH’s 3 hours, though the models have different output ratings and runtime conditions matter. The WGen9500DFc supplies 9,500 running watts on gasoline and 8,500 on propane, below both the XP13000EH and WGen10500DFc. A CO sensor with automatic shutdown adds a safety feature, but it does not make indoor operation safe; generators must be used outdoors. At 212.1 pounds, it still needs a deliberate storage and placement plan.
Pros:- Remote, electric, and recoil starting provide multiple ways to start the unit.
- 6.6-gallon tank is rated for up to 12 hours of runtime.
- Runs on gasoline or propane, with output figures listed for both fuels.
- CO sensor and automatic low-oil shutdown add protective functions.
Cons:- Gasoline running output is lower than the DuroMax XP13000EH and Westinghouse WGen10500DFc.
- At 212.1 pounds, it is not easy to lift or move by one person.
- Minimal assembly is required before operation.
Best for: Homeowners who want remote and electric startup, several fuel options, and a large tank for outage use without stepping up to the highest-output models.
Not ideal for: Buyers who need over 9,500 gasoline running watts or expect to carry the generator without wheeled assistance.
- Fuel type:Gasoline or propane
- Engine:457cc, 4-stroke OHV
- Peak output:12,500 watts gasoline; 11,200 watts propane
- Running output:9,500 watts gasoline; 8,500 watts propane
- Tank capacity:6.6 gallons
- Runtime:Up to 12 hours
- Starting methods:Remote, electric, and recoil
- Weight:212.1 pounds
Our verdict“Pick the WGen9500DFc if remote starting and longer stated runtime suit your outage routine better than the greater output of larger alternatives.”
Westinghouse WGen3600DFcv Dual-Fuel Portable Generator
The Westinghouse WGen3600DFcv is a better fit for targeted backup than for powering a whole home. With 3,600 running watts on gasoline and 3,240 on propane, it can serve selected essentials while avoiding the footprint and heft of large units such as the DuroMax XP13000EH. Its TT-30R and L5-30R outlets make RV or compatible 30-amp connections more natural than on a typical high-output home-backup setup. The listed gasoline runtime reaches 14 hours, and a 20-pound propane tank is listed for up to 16.5 hours; the propane figure depends on supplying that separate tank. This model gives up the high-load capacity and 240-volt output buyers may want for broader home circuits. CO shutdown, low-oil shutdown, and overload protection add useful safeguards, but the 120-volt design keeps its role focused.
Pros:- Gasoline and propane operation offers fuel flexibility for camping or backup.
- RV-ready TT-30R and 30-amp L5-30R outlets support compatible connections.
- Listed runtime reaches up to 14 hours on gasoline or 16.5 hours with a 20-pound propane tank.
- CO and low-oil shutdown, overload protection, and voltage regulation are included.
Cons:- Running output is far below the DuroMax XP13000EH and other large home-backup models.
- 120-volt output limits its fit for homes needing 240-volt circuits.
- The propane runtime depends on a separate 20-pound tank, which is not part of the generator’s fuel capacity.
Best for: RV owners and households planning to power a limited set of 120-volt essentials rather than run multiple large appliances or broad home circuits.
Not ideal for: Homeowners who need 240-volt output or the capacity to support many high-draw household loads at once.
- Fuel type:Gasoline and propane
- Engine:212cc, 4-stroke OHV
- Peak output:4,650 watts gasoline; 4,180 watts propane
- Running output:3,600 watts gasoline; 3,240 watts propane
- Fuel tank capacity:4 gallons
- Runtime:Up to 14 hours per gasoline tank; up to 16.5 hours on a 20-pound propane tank
- Outlets:120V household duplex, TT-30R 30A, and L5-30R 30A
- Safety features:Automatic low-oil and CO shutdown, overload protection, voltage regulation
Our verdict“Choose this Westinghouse for RV-ready 120-volt power and modest essentials, not for broad whole-home backup.”
Westinghouse WGen10500DFc Dual Fuel Portable Generator with CO Sensor
For buyers balancing high output with fewer fuel stops, the Westinghouse WGen10500DFc stands out with 10,500 running watts and a 9.5-gallon tank rated for up to 19 hours at 25% load on gasoline. That runtime qualification matters: it is not a promise of 19 hours at heavy demand. The unit’s gasoline running output matches the DuroMax XP13000EH, while its stated fuel capacity and runtime make it a more appealing fit for lighter overnight loads. Remote and electric start, with recoil backup, give owners several startup options; a CO sensor and low-oil shutdown add safeguards. It runs on propane too, though the supplied information does not give propane output or runtime figures. The transfer switch is sold separately, so factor the connection setup into a home-backup plan.
Pros:- 10,500 running watts provide capacity for substantial household backup loads.
- 9.5-gallon tank is rated for up to 19 hours at 25% load on gasoline.
- Electric, remote, and recoil starting give multiple startup options.
- CO sensor, low-oil shutdown, and overload protection are included.
Cons:- The transfer switch is sold separately.
- The 19-hour runtime applies at 25% load on gasoline, not at full output.
- Propane output and runtime figures are not provided in the supplied product data.
Best for: Homeowners who need 10,500 running watts and want a large gasoline tank for extended low-load operation during outages.
Not ideal for: Buyers who require a transfer switch in the box, need confirmed propane runtime figures, or expect the maximum stated runtime at heavy load.
- Fuel type:Gasoline and propane
- Engine:500cc, 4-stroke OHV
- Starting wattage:13,500 watts
- Running wattage:10,500 watts
- Tank capacity:9.5 gallons
- Runtime:Up to 19 hours at 25% load on gasoline
- Starting system:Electric start, remote key fob, and recoil backup
- Safety features:CO sensor, automatic low-oil shutdown, and overload protection
Our verdict“Choose the WGen10500DFc for high output and long stated gasoline runtime at light load, while planning separately for transfer-switch equipment.”
WEN DF360iX Quiet and Lightweight 3600-Watt Dual-Fuel RV-Ready Portable Inverter Generator
The WEN DF360iX takes a different approach to home backup than the large open-frame units here: it favors quiet operation, portability, and clean power over high wattage. At 49 pounds and a stated 65 decibels at quarter load, it is much easier to move and less intrusive than the 212-pound Westinghouse WGen9500DFc. Its inverter output is specified for sensitive electronics, while the TT-30R outlet supports compatible RV connections. The tradeoff is firm: its 2,900 rated gasoline watts and 2,600 rated propane watts are for a limited load plan, not broad household backup. Fuel shutoff helps use fuel left in the carburetor before shutdown, which can reduce stale-fuel maintenance concerns. A separate WEN parallel kit can link two compatible inverter units, but adds equipment and does not make this a standalone high-capacity generator.
Pros:- 49-pound design is far easier to move than the large home-backup generators in this lineup.
- Inverter power is specified for sensitive electronics, with low harmonic distortion.
- Dual-fuel operation and a tool-free LPG quick-connector simplify propane connection.
- CO Watchdog shutdown, fuel shutoff, and overload protection support safer, lower-maintenance use.
Cons:- Rated output is limited to 2,900 watts on gasoline and 2,600 watts on propane.
- Provides 120-volt output rather than the 240-volt connection available on larger backup models.
- Parallel connection requires a separate kit and another compatible inverter generator.
Best for: Buyers who need portable, quieter power for electronics, a few essential devices, or RV use, and who can keep their backup load modest.
Not ideal for: Households needing 240-volt output, high running wattage, or enough capacity to support several large appliances during an outage.
- Fuel type:Gasoline and propane
- Engine:149cc, 4-stroke
- Surge output:3,600 watts gasoline; 3,500 watts propane
- Noise level:65 decibels at quarter load
- Fuel tank:1.5 gallons
- Runtime:Up to 5 hours at half load on gasoline; up to 14 hours at half load on a 20-pound LPG tank
- Weight:49 pounds
- Outlets:Two 120V household receptacles, TT-30R RV receptacle, 12V DC receptacle, and two 5V USB ports
Our verdict“Choose the WEN DF360iX for portable, quieter inverter power and electronics, but skip it if your outage plan needs large-appliance capacity.”
Westinghouse WGen9500DF Dual Fuel Portable Generator, 12,500-Watt Peak
The WGen9500DF pairs 9,500 running watts on gasoline with three starting methods, including a remote key fob. That makes it a strong fit for households that want substantial backup capacity without relying on a pull cord during an outage. Its 50A outlet suits a compatible transfer-switch setup, while the RV outlet adds flexibility beyond home backup. Compared with the DuroMax XP13000HX, it offers less stated gasoline output but includes remote starting and a specified 12-hour runtime from its 6.6-gallon tank. Propane output is lower at 8,500 running watts, so buyers should size their essential loads around the chosen fuel. The tradeoff is its heavy-duty form: wheels help, but they do not make a 9,500-watt-class generator easy to move, and some assembly is required.
Pros:- Provides 9,500 running watts on gasoline and 8,500 on propane.
- Remote, electric, and recoil starting give several ways to start it.
- 6.6-gallon tank is rated for up to 12 hours of runtime.

Best for: Households seeking high-capacity backup, remote start, and a 50A connection for a compatible transfer-switch setup.
Not ideal for: Buyers who need a light, compact generator or who want the highest listed output in this group; the DuroMax XP13000HX lists 13,000 watts.
- Gasoline output:12,500 peak watts; 9,500 running watts
- Propane output:11,200 peak watts; 8,500 running watts
- Engine:457cc, 4-stroke OHV
- Fuel tank:6.6 gallons
- Runtime:Up to 12 hours
- Starting methods:Remote, electric, and recoil
- Outlets:Two 120V 20A GFCI; one 120V 30A L14-30R; one 120/240V 50A 14-50R
- Warranty:3-year limited
Our verdict“Choose the WGen9500DF if you want substantial dual-fuel backup with remote starting and can accommodate a large, heavy generator.”
Westinghouse 6600 Watt Dual Fuel Home Backup Portable Generator with Remote Electric Start and CO Sensor
This Westinghouse is the middle-capacity choice here: its 5,300 running watts are well below the WGen9500DF’s gasoline output, but may suit buyers prioritizing essential circuits rather than broad whole-home coverage. Remote electric start reduces the effort of getting it running, and the CO sensor with automatic shutdown adds a layer of protection; it does not replace safe outdoor placement. The 30A transfer-switch-ready and RV outlets give it a more practical home-and-recreation setup than a basic portable model. Its 4.7-gallon tank is rated for up to 14.5 hours at 50% load, though that figure depends on load and fuel. Compared with the similarly rated WGen5300DFcv, this version specifies remote start and a CO sensor, while neither is a high-output substitute for the larger generators in this roundup.
Pros:- Offers gasoline and propane operation with 5,300 running watts listed.
- Remote electric start adds convenience during an outage.
- CO sensor, low-oil shutdown, and overload protection provide useful safety features.

- Safety features:CO sensor, automatic low-oil shutdown, overload protection, voltage regulation
- Warranty:3-year limited service, labor, and parts
Our verdict“Pick this Westinghouse for moderate backup loads and remote-start convenience, not for whole-home-level capacity.”
DuroMax XP13000HX 13,000-Watt Dual-Fuel Portable Generator
With 13,000 watts listed, the XP13000HX is the highest-output option in this set by its stated wattage, making it the clearest fit for buyers trying to support more household loads from one portable generator. Its 50A outlet is ready for a compatible transfer-switch connection, and the 500cc engine, electric start, and CO Alert round out a home-backup-focused package. Against the Westinghouse WGen9500DF, the DuroMax lists higher output, while the Westinghouse provides specified gasoline and propane running figures, remote starting, and a 12-hour tank runtime. The XP13000HX’s supplied data does not break its 13,000-watt figure into fuel-specific peak and running output, so buyers should confirm the ratings they need for their fuel and loads. At 245 pounds and roughly 30 by 29 by 26 inches, it is portable in category, not easy to handle alone.
Pros:- Lists 13,000 watts for high-demand backup use.
- Runs on gasoline or propane.
- Includes electric start, CO Alert, and a digital display.
- 50A outlet supports a compatible transfer-switch setup.
Cons:- At 245 pounds, it is difficult to move without help.
- Large dimensions require substantial storage and operating space.
- Provided specifications do not separate peak and running output by fuel.
Best for: Homeowners who need the highest listed output in this group and have a planned transfer-switch connection and space for a large generator.
Not ideal for: People who need frequent solo relocation or want clearly stated fuel-specific running-watt ratings before choosing loads.
- Listed wattage:13,000 watts
- Fuel types:Gasoline and propane
- Engine:500cc, four-stroke OHV
- Starting system:Electric start
- Runtime:Up to 17 hours
- Outlets:Four 120V GFCI; one 120V 30A; one 120/240V 30A twist-lock; one 120/240V 50A
- Weight:245 pounds
- Dimensions:30 x 29 x 26 inches
- Safety and monitoring:CO Alert and digital display
Our verdict“Choose the XP13000HX when maximum listed output matters more than easy handling or detailed fuel-specific wattage figures.”
Westinghouse WGen5300DFcv Dual-Fuel Portable Generator with CO Sensor
The WGen5300DFcv is the more restrained home-backup pick: it supplies 5,300 running watts on gasoline and 4,800 on propane, enough for a more focused set of essential loads rather than the broader demand suited to the DuroMax XP13000HX. Its 30A L14-30R outlet supports a compatible transfer-switch connection, while the TT-30R outlet makes it a natural fit for RV use. A CO sensor with automatic shutdown and low-oil shutdown add useful safeguards, and the wheel kit helps with repositioning. Runtime is listed at up to 14.5 hours from a 4.7-gallon tank, but this is not a high-capacity substitute for the WGen9500DF when more circuits need power. The lower output is the central compromise; buyers should also account for minimal assembly before use.
Pros:- Provides 5,300 running watts on gasoline and 4,800 on propane.
- Includes RV-ready and 30A transfer-switch-ready outlets.
- CO sensor with automatic shutdown and low-oil shutdown are included.
- Wheel kit, propane hose, and tool kit support setup and movement.
Cons:- Capacity is limited for households seeking broad or high-demand backup.
- Some assembly is required before use.
- Its 4.7-gallon tank is smaller than the WGen9500DF’s 6.6-gallon tank.
Best for: RV owners and households seeking moderate essential-load backup with dual-fuel flexibility, a 30A transfer-switch outlet, and built-in CO protection.
Not ideal for: Buyers who need to run several high-wattage appliances together or want a 50A connection and the higher capacity of the WGen9500DF.
- Gasoline output:6,500 peak watts; 5,300 running watts
- Propane output:5,800 peak watts; 4,800 running watts
- Fuel types:Gasoline and propane
- Engine:274cc, 4-stroke OHV
- Fuel tank:4.7 gallons
- Runtime:Up to 14.5 hours
- Outlets:5-20R 120V duplex; TT-30R 30A; L14-30R 30A
- Safety features:CO sensor with automatic shutdown; low-oil shutdown
- Warranty:3-year limited
Our verdict“Choose the WGen5300DFcv for RV use and essential home circuits, but step up to a larger model for heavier household loads.”
How We Picked
I ranked these models around the job a home backup generator needs to do: deliver enough usable power for the household’s priority loads, start and operate in a way the buyer can manage, and offer fuel flexibility that makes sense during an outage. I gave weight to the stated wattage class, electric or remote-start features, inverter design where relevant, CO-safety features, and transfer-switch readiness. I also separated compact, lower-output models from large open-frame units rather than treating one type as universally better.
The order reflects fit and versatility, not a claim that the highest peak-watt figure wins. The WGen11500DFc leads as a balanced high-capacity dual-fuel option; the 13,000-watt-class DuroMax and DuroStar models follow for buyers who need more headroom. Smaller Westinghouse and WEN options rank higher for specific use cases than their output alone would suggest, while the Westinghouse tri-fuel model is included as a useful comparison but is not a dual-fuel match. Before purchase, confirm each model’s current specifications, fuel-specific running output, outlet configuration, and connection requirements.

Factors to Consider When Choosing Dual Fuel Home Generators
Choosing among these generators starts with the loads you actually want to run, not the biggest number on the product label. I’d make a short list of essential appliances, check their starting and running demands, then weigh fuel logistics, connection plans, noise, storage, and safe placement. These decisions can change which size and style is the sensible choice.
Size the Generator Around Starting Loads
List the appliances you expect to use at the same time, then separate their running watts from the brief surge needed to start motors. Refrigerators, well pumps, sump pumps, and air conditioners can have starting demands far above their normal draw. A generator’s peak rating is not the same as the power it can sustain, so compare the running-watt figure for the fuel you intend to use. Avoid adding every appliance in the house unless you truly plan to run them together. A smaller unit paired with a deliberate load plan may be easier to store and operate than a large generator bought for rare simultaneous use. If a major motor load is involved, confirm its startup requirements with the appliance manufacturer or an electrician before choosing.
Treat Gas and Propane as Different Outage Plans
Dual fuel is most useful when you have a practical plan for both fuels. Gasoline is widely available in normal conditions, but long outages can complicate refilling and safe storage; propane can be stored for longer, but tank capacity and refills still limit runtime. Generator output may also differ between gasoline and propane, so compare fuel-specific ratings rather than assuming equal performance. Check which tank sizes and connections the unit supports, and confirm whether a regulator or hose is included. A common mistake is choosing propane for storage convenience without estimating how much fuel extended operation will require. The best choice depends on local supply, storage rules, and the loads you need to keep running.
Plan the Home Connection Before Buying
Transfer-switch readiness does not mean a generator can be connected directly to a home panel without the correct equipment. Ask a licensed electrician whether your panel needs a transfer switch or another approved connection method, and confirm the generator’s outlets and amperage match that setup. Never backfeed a home through a wall outlet; that can put utility workers and household members at risk. Buyers who only need a few appliances may prefer a properly rated extension-cord plan, while panel connection offers a more convenient way to power selected circuits. Decide this early because the connection method can affect both the generator model and installation work. Verify compatibility with the specific generator, panel, and chosen transfer equipment.
Choose Between Inverter and Open-Frame Designs
Inverter generators such as the WEN DF360iX and PowerSmart 3800 prioritize a more portable package and generally quieter operation than large open-frame units. That makes them attractive for modest backup loads or situations where noise and movement matter, but their lower output may not cover larger household equipment. Open-frame generators in the 9,500- to 13,000-watt classes offer more capacity, though they take more room and can be louder and heavier to handle. Do not assume that a compact inverter can support a whole home simply because it is marketed for backup. Match the design to the operating location, mobility needs, and appliances on your load list. If sensitive electronics are a priority, check the model’s power-quality specifications rather than relying on design labels alone.
Account for Safe Placement and CO Protection
Every portable generator must operate outdoors, well away from doors, windows, and vents, because carbon monoxide can build up indoors or enter a home. A CO sensor is a useful added safeguard, but it is not a substitute for safe placement, working carbon-monoxide alarms, or following the manual. Before buying, identify a stable outdoor location that leaves room for ventilation and keeps exhaust away from people and neighboring buildings. Also plan how to protect the unit from rain without enclosing it or restricting airflow. Buyers sometimes focus on the generator’s safety feature and overlook the cable route, weather exposure, and distance to the home. If your site cannot meet the manufacturer’s clearance guidance, reconsider where and how you will run the unit.
Compare Convenience Features With Maintenance Needs
Remote electric start can reduce effort during an outage, while a CO sensor adds a layer of risk detection; neither replaces routine upkeep. Check the manual for oil changes, fuel-system care, battery maintenance, and recommended exercise intervals before deciding which features matter most. Stored gasoline can degrade, so a fuel plan may include stabilizer or periodic rotation; propane avoids that particular issue but still requires attention to connections and tank supply. Wheels and handles matter if the generator must be moved, but they do not make a heavy unit effortless to position. Spending more for convenience makes sense when it solves a real operating problem, such as difficult starting or frequent movement. Choose a model whose maintenance schedule and handling demands fit the people who will operate it.
Frequently Asked Questions
Is an 11,500-watt generator enough to run my whole house?
It may run many household essentials, but the label alone cannot confirm whole-home coverage. Your result depends on the generator’s sustained output on the chosen fuel, the starting demands of equipment such as air conditioners and pumps, and which appliances run at the same time. Make a load list and have an electrician check the intended panel connection and circuit plan. Many households use a generator to power selected circuits rather than every appliance. Compare the WGen11500DFc’s fuel-specific ratings with your actual loads before treating it as a whole-home solution.
Should I choose a 13,000-watt model over the WGen11500DFc?
Choose a 13,000-watt-class unit only if its additional capacity addresses a real load or startup requirement. The DuroMax XP13000EH, XP13000HX, and DuroStar DS13000MX may appeal to households with larger demands, but a bigger generator also asks for more storage space, handling effort, and fuel planning. Compare running output, outlet layout, fuel-specific ratings, and transfer equipment compatibility rather than relying on peak wattage. If your priority circuits fit within the WGen11500DFc’s usable capacity, the larger class may add bulk without improving your day-to-day outage plan. An electrician can help check demanding motor loads before you commit.
Can I run a dual fuel generator on propane for the full outage?
Potentially, but the answer depends on your generator’s propane output, tank size, load, and access to refills. Propane output can differ from gasoline output, and a high continuous load will use fuel faster than light intermittent operation. Estimate runtime using the manufacturer’s fuel-consumption information at a comparable load, then decide how many tanks your outage plan requires. Check that the tank, hose, regulator, and connection are approved for the specific model. Propane storage can be convenient, but it is not a guarantee of unlimited fuel during a prolonged outage.
Is an inverter generator a better home backup choice than an open-frame generator?
Neither design is universally better; they serve different load and location needs. The WEN DF360iX and PowerSmart 3800 are lower-output inverter choices suited to buyers who value portability and quieter operation, while larger open-frame models can support heavier household loads. If you need to run a well pump, central air, or several major appliances, verify that an inverter model can meet both running and startup demands before choosing it. If your plan centers on a refrigerator, lights, and electronics, a smaller unit may be a better fit. Compare sound, power quality, weight, and actual ratings for the exact model.
Do I need a transfer switch if a generator is transfer-switch ready?
Transfer-switch readiness means the generator can work with compatible transfer equipment; it does not mean the equipment is installed or that direct panel connection is safe. A qualified electrician can identify the appropriate switch or approved interconnection method for your home and confirm it matches the generator’s outlet and electrical ratings. Never connect a portable generator by plugging it into a household wall outlet, since that can backfeed power onto utility lines. If you only plan to power a few devices, properly rated outdoor extension cords may be an option when used according to the manual. Decide on the connection method before purchase so the generator and home setup work together.
Conclusion
For most buyers who want substantial, flexible backup power, I’d choose the Westinghouse WGen11500DFc as the best overall starting point. The best high-capacity picks are the DuroMax XP13000EH, XP13000HX, and DuroStar DS13000MX, with the right choice depending on verified specifications, outlets, and connection plans. For a more modest home backup setup, the Westinghouse 6600 Watt or WGen5300DFcv may better match essential loads, while the WEN DF360iX is my beginner-friendly pick for buyers prioritizing a smaller inverter format and manageable power needs. The best value choice is a correctly sized model, not automatically the one with the largest wattage; the WGen9500DFc offers a middle ground for buyers who need more capacity than compact options provide. For portable, lower-noise use, compare the PowerSmart 3800 and WEN inverter, and for households considering three fuels, assess the Westinghouse tri-fuel model separately because it does not match this dual-fuel category exactly. Before settling on any pick, confirm fuel-specific output, safe outdoor placement, and compatibility with your home’s planned connection.
