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 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.

The Westinghouse 11000 Peak Watt Dual Fuel Portable Inverter Generator is a solid choice for those needing reliable power for residential use, outdoor activities, or emergency situations. With a power output of 9000 running watts (gasoline) and 8100 (propane), it’s capable of handling various devices safely due to its low THD of less than 3%. This makes it a great option for powering sensitive electronics like computers and TVs.

One of the standout features is its long runtime of up to 17 hours on a single tank of fuel, thanks to its generous 9.8-gallon capacity. Users will appreciate the remote electric start, which adds convenience, allowing you to start the generator from a distance without hassle. Furthermore, it includes multiple outlets, making it adaptable for different needs, whether using standard household items or connecting a transfer switch for more extensive power requirements.

Portability is another strong point, although the generator weighs 187.4 pounds, making it less than ideal for transport over long distances. Still, its rugged design ensures durability, and the wheels help with mobility. The built-in CO sensor enhances safety, alerting users to dangerous carbon monoxide levels. The weight can be a challenge for some users, especially if portability is a primary concern. Also, while the generator is designed for dual fuel use (gas and propane), switching fuels may require additional setup. Lastly, while its design is user-friendly, some newcomers might find the features and functions slightly overwhelming at first.
