10 Best Inverter Generators 2026 in the United States

The Westinghouse 11000 Peak Watt Tri-Fuel Portable Inverter Generator offers a powerful solution for those needing flexible, reliable backup or outdoor power. With a high running wattage of 9000 on gasoline and substantial output on propane and natural gas, it can handle whole-home backup tasks or heavy-duty tools, making it ideal for residential use and extended camping trips. Its tri-fuel capability adds versatility, allowing you to switch between gasoline, propane, or natural gas depending on availability and cost, which can save money over time.

The inverter technology means it adjusts engine speed to match power needs, improving fuel efficiency and reducing noise to about 76 dBa, which is quieter than many traditional generators but still noticeable. A big plus is its low total harmonic distortion, making it safe for sensitive electronics like laptops and TVs. It includes convenient features such as a digital LED display for monitoring fuel and output, remote start for ease of use, and transfer switch-ready outlets for home integration. Safety is enhanced with a built-in CO sensor and automatic low oil shutdown.

One downside is the generator's weight of 191 pounds, reducing portability despite the flat-free tires, so it is best suited for users who can manage its size or keep it stationary most of the time. Its price and size place it in the higher-power category rather than a lightweight camping unit. For those needing strong, flexible power with clean output and modern features—and who don't mind the weight—this Westinghouse model is a solid choice.

The DuroMax XP16000iH is a powerful inverter generator delivering up to 16,000 peak watts and 13,000 running watts, making it suitable for whole-home backup during emergencies or demanding job sites. Its dual fuel capability lets you run it on gasoline or propane, providing flexibility if one fuel source runs out. It uses inverter technology to supply cleaner and more stable power, which is safer for sensitive gadgets like computers and TVs. Remote electric start and a battery tender make it easy to use and keep ready at all times. The digital control center displays useful information such as voltage and run time, which is helpful for monitoring performance. Safety features like low oil shutoff and a CO sensor add peace of mind during use. It meets EPA and CARB emissions standards, ensuring it’s environmentally friendlier than many others in this size range.

At 368 pounds, it is quite heavy, which limits portability for casual camping or frequent moves — you’ll likely need wheels or a dolly to transport it. The fuel tank holds 10.5 gallons, implying good runtime but also adding to weight. The generator comes with several outlets and includes helpful accessories like a propane regulator and remote control.

If you need high power output with fuel flexibility and remote operation for home backup or heavy-duty use, this generator fits well. However, if you want something lightweight for easy transport or very quiet operation, smaller or quieter models might be more suitable.

The Westinghouse iGen8200TFc is a strong choice for anyone needing reliable backup power at home or on the go. It delivers solid wattage with 6600 running watts and 8200 peak watts on gasoline, enough to run essential household appliances like air conditioners and refrigerators simultaneously. Its tri-fuel capability (gas, propane, and natural gas) adds great fuel flexibility, making it convenient and potentially more economical depending on your fuel availability. The inverter technology adjusts engine speed to reduce fuel consumption and noise, running at a quieter 60 decibels at 25% load, so it won’t be overly disruptive during use. It also offers clean power with less than 3% total harmonic distortion, meaning it’s safe for sensitive electronics such as phones and computers.

For added safety, it includes a carbon monoxide sensor and automatic low oil shutdown. The generator is somewhat heavy at about 135 pounds, but features like flat-free tires and remote electric start improve portability and ease of use. It’s also parallel capable, allowing you to connect another unit for more power if needed. Outlet options include a 50A 120/240V for home backup, a 30A RV outlet, and a standard 20A outlet, covering a wide range of uses.

The weight might be a challenge if you need frequent transport, and while quieter than conventional generators, it’s not silent. Also, tri-fuel setups can require some extra maintenance knowledge. For home backup, camping, or work sites that need versatile, clean, and dependable power, this Westinghouse inverter generator balances power, safety, and fuel efficiency well.
