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 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.

The Westinghouse 12500 Peak Watt Dual Fuel Generator offers strong power output, with 9500 running watts on gasoline and slightly less on propane, making it well-suited for home backup during outages. Its 6.6-gallon fuel tank provides up to 12 hours of runtime, which is practical for extended use. Being dual fuel (gasoline and propane) adds flexibility depending on fuel availability. It includes a remote electric start with a key fob, which is convenient, plus a recoil start as backup.

The generator features multiple outlets, including household standard plugs, a transfer switch ready outlet, and an RV-ready outlet, covering a broad range of common needs. Safety features like a CO sensor and automatic low oil shutdown enhance peace of mind. At about 225 pounds, it is quite heavy, so while it has a front handle, it might be challenging to move frequently without assistance. Noise is rated around 74 dB, which is noticeable but typical for this power size and may require consideration if you need something quieter.

Additional useful features include a fuel gauge, USB port, hour meter, and accessories such as an LPG regulator and battery charger. This generator is a solid choice for homeowners needing dependable, flexible power for backup or outdoor use, though its weight and noise may be less ideal for those prioritizing portability or quiet operation.
