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 WEN 11,000-Watt Dual Fuel Portable Generator is a strong choice for those needing reliable power at home or outdoors. It delivers up to 8,300 running watts on gasoline and 7,500 watts on propane, which is enough to handle heavy-duty appliances or multiple devices during an outage. The generator offers flexibility with easy switching between gasoline and propane, plus it supports both 120V and 240V outputs, making it compatible with various power needs including emergency transfer switches.

Starting the generator is hassle-free thanks to its electric start system, so you don't have to rely on a pull cord. It has a large 6.6-gallon tank that provides up to 8.5 hours of run time at half load when using gasoline, which is decent for extended use. However, keep in mind it weighs 214 pounds, so while it comes with wheels for mobility, it’s not very lightweight or compact for frequent transport.

Fuel efficiency is reasonable, especially with propane as a cleaner-burning option, though the propane run time is lower than gasoline. The generator includes multiple outlets for different plug types, covering a wide range of device connections, and even comes with a propane hose and oil to get started right away. The two-year warranty adds some peace of mind. This WEN model suits users looking for a powerful, flexible dual-fuel generator with electric start and versatile outlets. It is better suited for stationary use or occasional transport rather than frequent moving, and while it provides solid run time and power, noise and weight could be considerations depending on your needs.
