10 Best Dual Fuel Generator 2026 in the United States

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.

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 Westinghouse 14500 Peak Watt Dual Fuel Generator is a strong choice for homeowners needing a reliable backup power source, especially for larger homes or extended outages. It delivers a powerful 14,500 peak watts on gasoline and 13,500 on propane, which is enough to run multiple appliances or essential home systems simultaneously. The large 9.5-gallon gas tank allows it to run up to 19 hours on gasoline, which is excellent for longer use, although propane runtime is shorter at around 7 hours with a standard 20-pound tank. This generator offers fuel flexibility, allowing you to switch between gas and propane based on availability or preference.

For starting, it includes a convenient electric start with remote key fob, making it easy to operate without manual effort. It also features automatic voltage regulation and safety components like a CO sensor and overload protection, which help keep your devices safe and the generator running smoothly. On the downside, it weighs 230 pounds, so it's not very portable; you’d likely need wheels or assistance to move it around. Larger generators like this are usually louder, so it might not be ideal for quiet neighborhoods.

It offers two power outlets at 240 volts, suitable for home use but might require additional connections for more devices. If you want a durable, high-capacity generator that can run on two types of fuel and start easily, this Westinghouse model is a solid pick, though it’s better suited for stationary use due to its weight.
