10 Best Inverter Generators 2025 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 Honda EU7000IS is a powerful inverter generator that delivers a starting wattage of 7,000 watts and a running wattage of 5,500 watts, making it a solid choice for home backup power, camping, or outdoor events. One of its standout features is the super quiet operation, which is a significant advantage if you want to avoid disturbing your neighbors or the peace of nature. The electric start adds convenience, letting you get the generator going with minimal effort, which is particularly useful in emergency situations.

In terms of fuel efficiency, this generator shines, providing a runtime of approximately 6 hours and 30 minutes at half load. This means you won't have to refuel as often, which adds to its usability for longer outdoor events or power outages. The advanced CO-MINDER system enhances safety by detecting carbon monoxide levels, which is a crucial feature for any generator used indoors or in enclosed spaces.

There are a few drawbacks to consider. At 270 pounds, it's relatively heavy, which may hinder portability, especially for users who need to transport it frequently. While it does have Bluetooth capability and a dedicated app for monitoring, the complexity of these features might be overwhelming for those who prefer straightforward operation. Additionally, despite its effectiveness, the price point might be higher than entry-level models, which could be a consideration for budget-conscious users.
