10 Best Dual Fuel Generator 2025 in the United States

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.

The Westinghouse 11000 Peak Watt Dual Fuel Portable Inverter Generator is a robust and versatile power solution, ideal for both home backup and outdoor activities. It delivers substantial power with 9000 running watts on gasoline and 8100 running watts on propane, making it suitable for heavy-duty usage. The generator can run up to 17 hours on a full 9.8-gallon tank, providing long-lasting performance, which is excellent for prolonged power outages or extended outdoor events.

One of its standout features is the remote electric start, which includes a key fob for added convenience, along with push button and recoil start options. This makes starting the generator hassle-free compared to manual start models. It includes a variety of outlets, including standard household outlets and transfer switch ready outlets, enhancing its connectivity options. The CO sensor and automatic low oil shutdown add layers of safety, making it a reliable choice for users concerned about operational safety.

Weighing 187.4 pounds, it is relatively heavy, which might affect portability despite the portable tag. However, its wheels and handle seem to compensate for this to some extent. The built-in LED data center is a useful feature, providing real-time information on fuel level, power output, and runtime, helping users manage their power usage effectively. The generator is EPA compliant and backed by a 3-year limited warranty, which adds to its reliability. While the high power output and numerous features make it a strong contender in its category, the weight could be considered a drawback for some users. Nonetheless, it stands out as a powerful, feature-rich option for those needing a reliable dual-fuel generator.

The DuroMax XP11000iH is a versatile and powerful dual-fuel generator with impressive features. It offers 11,000 peak watts and 9,000 running watts, making it suitable for emergency home power, job site usage, and camping with an RV. The dual-fuel capability allows you to use either gasoline or propane, offering flexibility in fuel choice, which is very handy during fuel shortages. Its CO Alert feature enhances safety by automatically shutting down the generator if unsafe levels of carbon monoxide are detected, which is a critical safety measure.

The inverter technology ensures that the power output is clean and stable, making it safe for sensitive electronics like computers and televisions. The remote start feature adds convenience, allowing you to start the generator from a distance. Additionally, it’s equipped to connect to an Automatic Transfer Switch (ATS) for seamless power transition during outages. The generator is also parallel capable, meaning you can connect two units for double the power output, although this requires a separate parallel kit. On the downside, this generator is quite heavy at 216 pounds, which could make portability a bit challenging despite its 'portable' label.

It comes with useful accessories like a propane regulator and hose, battery tender, and remote control. With a strong build and compliance with EPA and CARB standards, it also emphasizes environmental friendliness. This generator is robust, versatile, and packed with features that cater to both residential and commercial needs, though its weight and potential noise might be points to consider.
