10 Best Dual Fuel Generator 2025 in the United States

The DuroMax XP13000HX Dual Fuel Portable Generator is designed to provide robust power with its impressive 13,000-watt output, making it suitable for keeping a whole household running during a power outage. One of its key strengths is the dual-fuel capability, allowing it to run on either gasoline or propane. Propane is a beneficial option as it is cost-effective, clean-burning, and has a longer shelf life compared to gasoline. The generator's 500cc OHV engine and all copper windings contribute to its durability and longevity.

It also offers a wide variety of outlets, including a 50-amp outlet that is transfer switch ready, which is excellent for connecting directly to a home’s electrical system during emergencies. Additionally, the electric start and digital display enhance user convenience. On the downside, the generator is quite heavy at 245 pounds, which may affect portability despite the included wheel and handle kit.

Additionally, the fuel tank capacity of 0.5 gallons may require frequent refueling when running on gasoline, which could be a hassle during longer outages. However, with features like CO Alert for safety and the flexibility of fuel choice, the DuroMax XP13000HX is a strong contender for those seeking a reliable and powerful generator for residential use.

The WEN 11,000-Watt Dual Fuel Portable Generator offers robust power output suitable for a variety of applications, including residential use and camping. With the ability to switch between gasoline and propane, it provides flexibility depending on fuel availability. When using gasoline, it delivers 11,000 surge watts and 8,300 running watts, while propane offers 9,500 surge watts and 7,500 running watts. This makes it capable of powering multiple devices and handling significant loads, which is crucial for emergency backup or powering appliances at a campsite.

Additionally, its 6.6-gallon tank ensures up to 8.5 hours of runtime at half load, which is quite efficient for a generator of this size. The electric start is a convenient feature, simplifying the start-up process, especially in emergencies. The comprehensive range of outlets, including four 120V GFCI outlets, a 120V 30A twist lock outlet, a 120V/240V 50A outlet, and a 12V DC plug, ensures compatibility with various devices and tools.

At 214 pounds, portability might be a concern despite the included wheel kit. It might require extra effort to move around, especially on uneven terrain. The generator's dimensions are relatively compact for its power capacity, but its weight can still pose a challenge. This generator is ideal for users needing a reliable power source for home backup, camping, or any situation that demands a portable and flexible fuel option.

The Generac GP7500E is a strong choice if you need a reliable dual-fuel generator for home backup or jobsite use. It offers a powerful starting wattage of 9,400W and a running wattage of 7,500W, which can handle heavy electrical loads, making it suitable for emergency power or outdoor work. One of its standout features is the ability to run on both gasoline and propane, with a convenient fuel selector switch that lets you switch fuel types without shutting down the unit. The large 7.9-gallon fuel tank delivers an impressive runtime—up to 11 hours at half load on gas, though propane runtime is shorter at about 5 hours. It includes a helpful fuel gauge and an hour meter to track maintenance, plus safety features like automatic low oil shutdown and a built-in carbon monoxide sensor to alert you to dangerous fumes. Starting the generator is easy thanks to its electric start system.

On the downside, this unit weighs 204 pounds, making it less portable than smaller models, so it’s better for stationary use or occasional moves rather than frequent transportation. Noise levels are described as 'quiet' for its class, but as with many powerful generators, expect some sound during operation. It has four power outlets, providing flexibility for connecting various devices but lacks specialized USB or RV outlets. The Generac GP7500E is well-suited for homeowners or professionals who need a dependable, long-running generator that handles heavy-duty power needs with safety and convenience in mind.
