10 Best Trifuel Generators 2025 in the United States

The WEN 13,000-Watt Tri-Fuel Inverter Generator is a powerful and versatile option for anyone needing a reliable backup power source. Its ability to switch easily between gasoline, propane, and natural gas offers great flexibility depending on fuel availability or preference. It delivers strong power output, with up to 13,000 watts of surge power and 10,500 running watts on gasoline, which is ample for heavy-duty use, including running multiple household appliances or tools simultaneously.

This generator features a 7.1-gallon gas tank that can provide up to 7.7 hours of runtime at half load, which is decent for extended power needs. The electric start makes it easy to get going without the hassle of pull cords. Portability is helped by an included wheel kit despite the unit being quite heavy at around 247 pounds, so while it’s movable, it's not something you’d carry around casually. A notable safety feature is the WEN Watchdog carbon monoxide sensor that automatically shuts down the generator if CO levels become dangerous, adding peace of mind during indoor or close-quarters use. It’s also relatively quiet for a unit this size, making it suitable for residential use.

The variety of outlets, including standard 120V, 240V, transfer-switch, and USB outlets, makes it adaptable for different applications like emergency home backup, camping, or even charging electric vehicles. The weight and size make it less ideal for those seeking a lightweight or ultra-portable generator. Additionally, while it’s quieter than many similarly powerful generators, it is not silent and may still produce noticeable noise. Some users might also find the fuel consumption on gasoline comparatively high when running near maximum power. This generator is a strong choice for those who want a high-power, flexible fuel option with easy start-up and good safety features, especially for home backup or worksite use where weight is less of a concern.

The DuroMax XP15000HXT Tri Fuel Generator is a powerhouse that can generate up to 15,000 watts, making it well-suited for keeping your entire home operational during power outages. One of its standout features is its versatility in fuel choice, allowing you to run it on gasoline, propane, or natural gas, which provides significant flexibility depending on availability and cost of fuel sources. The generator’s powerful 500cc OHV engine is designed to deliver reliable performance. It also features a push-button and remote start, which simplifies the operation process, and a user-friendly front-facing interface for quick fuel type changes.

A variety of outlets, including a transfer switch-ready 50 amp outlet, ensures compatibility with a range of devices and applications. The fully-loaded power panel and advanced computer interface with a large LED display make monitoring and managing the generator straightforward, providing real-time information on gas usage, load, voltage, frequency, and run time. Additionally, the CO Alert feature is a crucial safety measure that automatically shuts down the generator to prevent carbon monoxide poisoning.

The 100% copper windings enhance durability and longevity, making it a reliable choice for both residential and commercial use. However, the generator is quite heavy at 362 pounds, which may impact its portability despite the included wheel and handle kit. Additionally, while it offers robust power and comprehensive features, the noise level could be a consideration for users in noise-sensitive environments. This product is ideal for those who need a high-capacity, versatile power backup solution with a strong emphasis on safety and ease of use.

The Westinghouse Outdoor Power Equipment 14500 Peak Watt Tri-Fuel Generator is a robust option for those in need of a reliable power source for their homes or during outdoor activities. With a peak wattage of 14,500 and running wattage of 11,500 when using gasoline, it offers substantial power output suitable for larger homes. It also supports propane and natural gas, providing versatility in fuel choice, which is a major plus for users wanting flexibility in their power options.

One of its standout features is the impressive runtime of up to 19 hours on a full tank, which is quite beneficial in extended power outages. The electric start is another user-friendly feature, making it easy to operate without manual cranking, though it's worth noting it weighs 230 pounds, which may affect portability.

The generator is designed with safety in mind, featuring overload protection and a CO sensor, which helps provide peace of mind while in operation. Additionally, the durable construction and a 3-year limited warranty back the product, showing Westinghouse's confidence in its reliability. While the generator is powerful, the noise level, typical for many generators, may be a concern for some users, especially in residential areas. Additionally, the size and weight might make it less ideal for frequent transport unless you have a suitable vehicle for it. The starting wattage is also lower when using propane or natural gas, which could limit some users' needs depending on their appliances.

This generator is a great fit for those looking for a dependable home backup power solution, particularly if they value flexibility in fuel types and long run times. It is most suitable for residential use but may not be the best choice for those needing frequent portability or quiet operation.
