10 Best Inverter Generators 2025 in the United States

The WEN DF451i inverter generator is a versatile choice for those needing reliable power on the go, especially RV owners or campers. It offers a solid power output with 4500 surge watts and a running capacity of up to 3500 watts on gasoline, and slightly less on propane, which provides flexibility with its dual-fuel design. The automatic fuel switch between propane and gasoline extends run time, which is convenient for longer use without manual intervention. Weighing 100 pounds, it’s not the lightest, but the built-in wheels and handle make it manageable for transport.

One of its strong points is quiet operation, running at about 58 dBA at quarter load, which is much lower than many standard generators and good for campsites or neighborhood use. The generator produces clean, stable power that protects sensitive electronics like phones and laptops from damage due to power fluctuations. It also includes useful features like keyless electric start, fuel shut-off for simple maintenance, several types of outlets including an RV-ready socket, and a handy digital display to monitor load and fuel. Runtime is around 9 hours on a full tank, which is decent for portable generators but may require refueling during extended use.

A possible drawback could be its weight compared to lighter inverter models, making it less ideal if you need something ultra-portable. This WEN model is highly suited for RV owners and outdoor enthusiasts who want a quiet, flexible, and fairly powerful generator that balances convenience with solid performance.

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.

The Westinghouse Outdoor Power Equipment 5000 Peak Watt Inverter Generator offers a strong power output of 5000 peak watts and 3900 running watts, making it suitable for both home use and travel trailers. Its less than 3% Total Harmonic Distortion (THD) ensures clean and stable power, which is crucial for sensitive electronics. The generator runs on gasoline and has a fuel tank capacity of 3.4 gallons, providing up to 18 hours of runtime, which is impressive for extended use without frequent refueling. It's also very fuel-efficient with an 'Economy Mode' to maximize efficiency.

The noise level is as low as 52 dBA, making it extremely quiet, which is a significant advantage for residential or campsite use where noise can be a concern. Portability is enhanced by its telescoping handle and wheel kit, although the unit is relatively heavy at 119 pounds, which might require some effort to move around. The remote electric start with an auto choke and the included key fob offers convenience, allowing you to start the generator from afar.

The LED data center provides useful information such as fuel level, power output, remaining runtime, voltage output, and lifetime hours, which helps in monitoring its performance and maintenance. On the downside, its weight could be a drawback for some users who need to transport it frequently. However, it comes with a 3-year limited service, labor, and parts warranty, ensuring support and reliability. This generator is a solid choice for those needing a dependable and quiet power source for residential areas, camping, or RV use.
