10 Best Inverter Generators 2025 in the United States

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 5000 Peak Watt Super Quiet Dual Fuel Portable Inverter Generator offers a strong combination of power, versatility, and convenience. With a peak power output of 5000 watts and running power of 3900 watts, it is capable of running essential appliances during power outages or while camping. It supports both gasoline and propane fuel types, providing flexibility. The 3.4-gallon gas tank provides a commendable runtime of up to 18 hours, which is quite efficient for its class.

Its noise level is impressively low, operating at around 52 dBA, making it suitable for use in quieter environments or at night. The generator's portability is enhanced by a telescoping handle, although its weight of 124.7 pounds might make it less easy to move for some users.

A notable safety feature is the CO sensor, which adds a layer of protection against harmful carbon monoxide buildup. The inclusion of RV-ready outlets and USB ports makes it versatile for both residential and outdoor uses. Additionally, the remote start function with a key fob adds convenience.

One area of concern could be its size, which at 29.6 x 21.5 x 24.3 inches, requires adequate space for storage. Furthermore, while the Total Harmonic Distortion (THD) is less than 3%, which is excellent for sensitive electronics, the generator may not suit those needing more compact solutions.

This generator is backed by a 3-year limited warranty and nationwide customer service, which is reassuring for customers considering after-sales support. This product is ideal for individuals seeking a quiet, efficient, and versatile generator for residential or RV use, but it may not be the best option for those who require a highly portable or compact solution.

The Generac 7153 GP3300i is a portable inverter generator with a power output of 3,300 starting watts and 2,500 running watts, making it suitable for camping trips, tailgating, and other outdoor activities. It operates on gasoline, which is easily accessible, and features a fuel-efficient engine with an Economy Mode to reduce fuel consumption and noise levels.

At 59.5 pounds, it is relatively lightweight and portable, although some might find it slightly heavy for frequent transportation. The generator's design includes TruePower Technology, which ensures clean and stable power, safe for sensitive electronics like smartphones and laptops. Additionally, it has two USB ports for convenient mobile device charging and an LED indicator system to alert users of low oil, overloads, and readiness status. The COsense Technology is a notable safety feature that stops the unit if harmful levels of carbon monoxide are detected.

While it is designed to be quiet, noise levels can still be noticeable in extremely quiet environments. The generator is also parallel-ready, allowing users to connect another unit for double the power output. The Generac 7153 GP3300i offers a solid balance of performance, safety, and convenience, though users should be aware of its weight and noise levels.
