10 Best Propane Generators 2025 in the United States

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.

The DuroMax XP13000HXT is a powerful tri-fuel generator that can run on gasoline, propane, or natural gas, making it a versatile choice for both residential and commercial use. With a peak wattage of 13,000 watts and a running wattage of 10,500 watts, it’s capable of keeping your entire home powered during outages or emergencies. One of its standout features is the CO Alert system that protects users from harmful carbon monoxide fumes, enhancing safety during operation.

Portability is a strong point, as it comes with a wheel and handle kit, allowing you to move it around with relative ease, despite its hefty weight of 240 pounds. The generator also boasts a push button and remote start, which simplifies operation. Users appreciate the digital display that provides essential information at a glance, and the array of outputs, including a 50-amp outlet for larger appliances.

The XP13000HXT does have some drawbacks. The noise level is rated at 74 dB, which may be considered loud for some users, particularly in residential areas. The runtime of around 8 hours on a half-gallon tank might require more frequent refueling if used continuously, depending on the load. Additionally, while the tri-fuel capability offers flexibility, not every user may need all three fuel types, and it may complicate the setup for those who prefer simplicity.

The DuroMax XP13000HX Dual Fuel Portable Generator offers a substantial power output of 13,000 watts, which is ideal for keeping an entire household running during power outages. It can operate on both gasoline and propane, providing flexibility and cost efficiency. Its 500cc OHV engine with all-copper windings is designed for durability, ensuring a long lifespan.

The electric start function makes it user-friendly, and the wide array of outlets, including a 50 amp outlet, enhances its versatility for residential use. Additionally, the generator features a CO Alert system for safety, which can give you peace of mind by protecting your family from harmful fumes. However, at 245 pounds, it is relatively heavy, which may limit its portability despite the included wheel and handle kit.

The fuel efficiency is bolstered by the option to use propane, known for its clean-burning and low-maintenance characteristics. The generator's run time will vary based on the fuel type and load, but propane generally offers a longer shelf life and easier storage. The DuroMax XP13000HX is a robust and versatile option that caters well to residential needs, especially for users looking for a reliable backup power source during emergencies, despite potential concerns with weight.
