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 18000 Peak Watt Dual Fuel Generator is a powerful home backup solution that runs on either gasoline or propane, giving you flexibility during outages. It delivers 14,500 running watts on gas and slightly less on propane, which is enough to power most household essentials and some heavy-duty tools. With a large 10.5-gallon fuel tank, it can run continuously for up to 11 hours on gasoline, which is helpful for extended use without frequent refueling. This generator includes a convenient electric start with a remote key fob, making it easy to get going from a distance.

It weighs 405 pounds, so while it has wheels and handles, it’s quite heavy and might not be very easy to move around frequently. One standout safety feature is the built-in carbon monoxide sensor that automatically shuts down the generator if dangerous fumes build up, adding peace of mind. The generator offers a good variety of outlets including standard household plugs, RV connections, and USB ports, making it versatile for many devices and appliances. It also has features like automatic voltage regulation and low total harmonic distortion, which help protect sensitive electronics like phones and computers.

Due to its size and weight, this model may not be ideal for those needing a more portable option. Also, while it’s transfer switch ready, setup for whole-home backup might require professional installation. If you want a robust, dual-fuel generator with remote start and safety features primarily for home backup or heavy-duty use, this model represents a strong candidate.
