10 Best Westinghouse Dual Fuel Generators 2026 in the United States

This Westinghouse tri-fuel generator is designed for large home backup power needs, offering strong performance with up to 28,000 peak watts on gasoline and a solid 20,000 watts running power. It supports three fuel types—gasoline, propane, and natural gas—giving you flexibility depending on what’s available, which is a big plus during extended outages. The 17.2-gallon gasoline tank provides around 13 hours of operation at a quarter load, so it can keep essential appliances running through the night. Starting the generator is simple thanks to its remote electric start and included key fob, which is convenient during emergencies. It also features multiple outlet options including 240V and 120V, and it’s transfer switch ready for connecting directly to your home’s electrical panel.

The generator is built tough with a 999 cc engine and has useful safety features like automatic low-oil shutdown and CO sensor. Although it weighs 557 pounds, it has large, never-flat wheels and foldable handles to help with moving it when needed. Noise levels are not specified, but large generators like this tend to be on the louder side, so it might be noticeable in quiet neighborhoods. The size and weight mean it's less suitable for casual or lightweight use but perfect if you want powerful, reliable backup for a bigger home or jobsite.

This model represents a solid option if your priority is high power output, fuel flexibility, and the convenience of remote start, though it requires some effort to maneuver and likely generates a fair amount of noise.

The Westinghouse 11000 Peak Watt Dual Fuel Portable Inverter Generator is a strong contender in the dual fuel generator category, particularly for residential use. It offers a powerful output of 9000 running watts and up to 11000 peak watts when using gasoline, and slightly less when running on propane. This versatility can be a significant advantage if you're looking to switch fuel sources based on availability or cost. With a substantial fuel tank capacity of 9.8 gallons, it boasts an impressive run time of up to 17 hours, making it suitable for extended use, such as during power outages or outdoor events.

Portability is also a selling point; while it weighs 187.4 pounds, it includes features like a remote electric start, which allows for easy operation without direct access. However, the weight might be a concern for some users when moving it around. The generator is equipped with various outlets and safety features, like rubber covers and a CO sensor, ensuring safe use for sensitive electronics.

One of the strengths is the digital display that shows key information such as fuel level and remaining run time, which is user-friendly for those who may not be tech-savvy. The low total harmonic distortion (THD) is another plus, ensuring that it’s safe for powering sensitive devices. The price point may be higher compared to more basic generators, but the added features and capabilities could justify that cost for those needing reliable power options. This generator is well-suited for homeowners looking for a reliable, versatile, and safe power solution for various situations.

The Westinghouse 12500 Watt Dual Fuel Generator is a solid choice for homeowners seeking a dependable power backup solution. With its impressive power output of 9500 running watts and 12500 peak watts using gasoline, or 8500 running watts and 11200 peak watts with propane, it provides ample energy for various household needs during outages. The generator runs for up to 12 hours on a 6.6-gallon fuel tank, which is efficient for extended use.

One of the standout features is its remote electric start, allowing for easy operation without needing to manually pull a cord. This is particularly helpful for those who may find it challenging to start a generator traditionally. The unit is equipped with multiple outlets, including options for standard household connections and RV use, further enhancing its versatility. Additionally, it boasts safety features like rubber outlet covers and automatic low oil shutdown, making it user-friendly.

Portability is an advantage as well, although at 210 pounds, it may require some effort to move around. While it is designed to be portable, users should consider whether they will need to frequently relocate it. Noise levels are relatively moderate for a generator of this capacity, but it might still be noticeable, especially in quiet residential areas. A minor drawback is that it’s fairly large, which could limit storage options if space is a concern. Also, while the generator includes a lot of useful accessories like a battery charger and an oil funnel, some users may find the assembly process a bit tedious despite the minimal assembly claim.
