10 Best Dual Fuel Generator 2026 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 Generac 12,500 Starting Watt Tri-Fuel Portable Generator is a solid choice if you need reliable power for home backup, job sites, or RV use. Its 9,500 running watts and 12,500 starting watts provide enough power to handle most essential appliances and tools, making it suitable for both emergency situations and work needs. One of its standout features is the tri-fuel capability, allowing you to switch between gasoline, propane, and natural gas, which adds flexibility depending on fuel availability. The 7.5-gallon fuel tank offers up to 9.5 hours of runtime at half load on gasoline, so it can keep running through extended outages or long workdays. Portability is decent for a generator this powerful, thanks to the heavy-duty wheels and steel frame, but at 219 pounds, it’s not something you’ll want to move frequently by yourself.

The electric start with a battery included is a big convenience, eliminating the hassle of manual pull starts. Covered outlets help protect against dust and moisture, and there are three power outlets to connect your equipment, though it doesn’t have an extensive variety of outlet types. Noise level isn’t specifically highlighted, but it’s described as quiet operation, which should be comfortable for most residential or job site environments. Additionally, built-in safety features like a CO sensor and low oil shutdown add peace of mind.

The main drawback is its weight, making it less ideal if you need a very portable option. Also, while it covers basic outlet needs, users requiring specialized connections might find it limited. This generator is well suited for those who want a powerful, durable, and flexible fuel source for backup or work purposes and are comfortable handling its weight.

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.

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.
