10 Best Propane Generators 2025 in the United States

The WEN 14,500-Watt Tri-Fuel Generator offers strong power output, with up to 14,500 surge watts on gasoline and respectable wattages when running on propane or natural gas, making it suitable for heavy-duty backup needs at home or on job sites. It supports both 120V and 240V, which is great for connecting to transfer switches for seamless power during outages. The electric start is a big convenience, allowing easy startup without pulling a cord.

With an 8.2-gallon fuel tank, it can run up to 12 hours at half load, so you get good fuel efficiency and longer operation without frequent refueling. This model is also equipped with a CO Watchdog sensor that automatically shuts the unit off if carbon monoxide levels get unsafe, adding an important safety feature. Portability is moderate since it weighs 252 pounds but comes with a wheel kit, making it easier to move around despite its size.

This generator is versatile thanks to the tri-fuel option, though the power output decreases when running on propane or natural gas compared to gasoline. The WEN generator is a solid choice for those who want a powerful, flexible, and relatively easy-to-use propane generator with important safety features, despite being a bit heavy and potentially louder than some smaller units.

The WEN 14,500-Watt Tri-Fuel Generator (TF1450) stands out for its versatile fuel options, allowing it to run on gasoline, propane, and natural gas. This flexibility is beneficial during fuel shortages or emergencies, making it a reliable backup power source. The generator offers strong power output, with up to 14,500 watts surge power on gasoline, ensuring it can handle heavy-duty appliances and tools.

It also supports both 120V and 240V outputs, which is ideal for transfer switches and various electrical needs. The electric start feature makes it easy to operate with a simple turn of a key. Additionally, it provides up to 12 hours of runtime at half load with its 8.2-gallon tank, which is quite substantial for prolonged use. The included wheel kit enhances portability, though at 249 pounds, it is quite heavy and might require effort to move around.

Fuel efficiency is a plus, given the multiple fuel options, although natural gas outputs lower wattage compared to gasoline and propane. The generator includes several useful outlets and necessary components, making setup straightforward. A three-year limited warranty adds peace of mind. This generator is particularly suitable for homeowners seeking a robust and versatile emergency power solution, though its weight could be a drawback for some.

The Westinghouse 28000 Peak Watt Tri-Fuel Generator is a powerhouse designed mainly for larger homes needing reliable backup power. It offers impressive wattage, delivering up to 28,000 peak watts on gasoline and 25,200 peak watts when running on propane, which is excellent for running multiple heavy appliances or essential home systems during an outage. With a large 17.2-gallon fuel tank, it can run up to 13 hours at 25% load, giving you substantial runtime for extended outages. It supports three fuel types—gasoline, propane, and natural gas—making it versatile and convenient depending on what fuel you have access to.

The generator includes electric and remote start, simplifying the startup process, which is a big help if you want to avoid manual pulls. Portability-wise, it weighs 557 pounds but features large never-flat wheels and foldable handles to assist with moving it around, although it won’t be as easy to transport as smaller units. Generators of this size tend to produce noticeable noise and are best suited for outdoor use rather than quiet environments. The built-in sensors, automatic idle control, and voltage regulation help protect your devices and improve fuel efficiency, while the low total harmonic distortion means it can safely power sensitive electronics like computers and TVs.

A potential downside is its size and weight, which may be cumbersome for some users, and it requires professional installation for the hardwired whole-home backup option. For those seeking a robust, reliable, and flexible generator for backup power in a larger home and who do not mind the bulk, this model represents a strong contender.
