10 Best Propane Generators 2026 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 Generac Guardian 10kW Home Standby Generator is designed to provide reliable backup power for your entire home, making it a strong choice for those preparing for storms or outages. It delivers a solid 10,000 watts of clean, stable power which is enough to keep essential appliances running smoothly. It operates quietly, especially during its self-test mode, which helps save fuel and reduces noise disturbance—a big plus if you want peace and quiet around your home.

This model runs on either natural gas or liquid propane, offering flexible fuel options that can fit various household setups. The generator features an electronic ignition system for easy and reliable starting, so you won’t have to worry about manual effort when power goes out. With its Wi-Fi connectivity, you can monitor its status remotely, giving you peace of mind even when you’re away.

Since it is designed to be a permanent home standby unit and weighs 338 pounds, it is not portable. However, it excels in durability and low maintenance thanks to its purpose-built engine. Installation requires a certified electrician, so it’s not a simple plug-and-play device but rather a solid investment for long-term home protection. This generator offers powerful, quiet, and efficient backup energy with smart features, ideal for keeping your home running smoothly during emergencies.

The DuroMax XP16000iH is a powerful dual-fuel generator capable of producing up to 16,000 starting watts and 13,000 running watts, making it well-suited for whole-home backup, job sites, or RV use. Its ability to run on both gasoline and propane offers great flexibility, especially if you want to switch fuels during longer outages or prefer propane for cleaner emissions. The generator features inverter technology, which means it provides stable power safe for sensitive electronics like laptops and TVs. Starting the unit is convenient thanks to the remote electric start, and the included battery tender helps keep it ready to go at all times.

It also has a digital control center with an easy-to-read display showing important information like run time and load. While the DuroMax XP16000iH is portable for its size, it weighs 368 pounds, so moving it around might require some effort or wheels. It has a large 10.5-gallon fuel tank.

An automatic low oil shutoff and EPA/CARB emissions compliance add safety and environmental friendliness. This generator is a robust, reliable power source capable of handling heavy loads, but if portability or quiet operation are top priorities, you might want to consider other options.
