10 Best Dual Fuel Generator 2025 in the United States

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 ERAYAK 4500W Dual-Fuel Portable Inverter Generator is a versatile choice for home backup, RV camping, and outdoor use. It supports both gasoline and propane, providing flexibility and longer runtime — about 16 hours on gas at a quarter load and over 20 hours when using propane. This allows power to last through the night without frequent refueling. With a peak power of 4500W and running power of 3500W on gas, it can handle most household essentials and RV appliances safely thanks to its clean power output (pure sine wave). It features several useful outlets including two 120V outlets, a 30A RV outlet, and USB ports, covering a wide range of devices.

Weighing just 54 pounds and compact in size, this generator is easier to carry and store than many other models, making it suitable for camping or moving around a job site. Its noise level is reasonably low at 58 dBA, so it won’t be too disruptive during use. The starting mechanism is a recoil start, which is simple but may require some effort compared to electric start models. Safety is enhanced by a built-in carbon monoxide sensor that can automatically shut down the generator if dangerous levels are detected. Additional perks include automatic fuel switching when gasoline runs out and electronic speed control to save fuel.

This generator provides a strong balance of power, portability, and safety features, making it well-suited for users who need reliable, flexible fuel options in a compact package. However, the lack of an electric start might be a downside for those wanting quick and easy startup, and while it’s fairly quiet, it’s not the quietest model available.

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.
