10 Best Quietest Generators 2025 in the United States

The Generac 18,000-Watt Gas-Powered Portable Generator is a robust option for those needing substantial power output. With an impressive 18,000 watts from its 816cc EFI engine, it is well-suited for emergencies, recreational use, and home backup power.

One of its standout features is the COsense Technology, which offers essential safety by protecting against carbon monoxide. Additionally, TruePower Technology ensures that sensitive electronics and tools can be safely powered, thanks to its low total harmonic distortion (THD) of less than 5%.

This generator also includes a low-oil pressure shutdown feature, which helps prevent engine damage and enhances its longevity. Its large fuel capacity allows for extended runtimes, making it durable for long-term use. However, at 442.8 pounds, it is quite heavy, which could impact its portability despite being labeled as portable. This weight makes it less ideal for frequent transport. The generator runs on gasoline, which is readily available but may not be as convenient as other fuel types like propane.

The Westinghouse 11000 Peak Watt Dual Fuel Portable Inverter Generator is a powerful and versatile generator suitable for a variety of needs. It produces 9000 running watts and 11000 peak watts on gasoline, and 8100 running watts and 10000 peak watts on propane. This makes it a strong contender for those needing substantial power output. Its dual fuel capability provides flexibility and convenience, allowing users to switch between gasoline and propane based on availability and preference.

The generator features inverter technology, making it safe for sensitive electronics by producing clean power with less than 3% Total Harmonic Distortion (THD). This is a significant advantage for households and businesses that need to power delicate devices. Portability is somewhat compromised by its weight of 187.4 pounds, although it’s designed with wheels and a handle to aid in moving it. The 17-hour runtime on a 9.8-gallon fuel tank is impressive, providing extended use without frequent refueling.

Additional features include a remote electric start, LED data center, GFCI outlets, and a CO sensor for safety. The generator is also transfer switch ready and can be used in parallel with another unit for increased power output. Its built-in safety features and ease of use make it a reliable choice for residential use. This generator balances power, safety, and versatility, making it well-suited for users needing a robust and flexible power source, though it may not be the quietest or most portable option available.

The Honda EU7000IS is an impressive choice for those in search of a quiet yet powerful generator. With a noise level that’s notably low, it's perfect for home backup power, outdoor events, and RV use, allowing you to enjoy activities without the disruptive hum of a traditional generator. One of its standout features is the electric start, which makes it incredibly user-friendly, especially for those who may not be accustomed to operating generators. The inclusion of Bluetooth capability and the Honda My Generator app also adds a modern touch, enabling users to monitor and control the generator remotely, ensuring convenience and ease of use.

Another strong point is its superior fuel efficiency, which means that it can run longer on less fuel, saving you money over time. The advanced CO-MINDER system is a significant safety feature, providing peace of mind by detecting harmful carbon monoxide levels and shutting the generator off when necessary.

There are a few considerations to keep in mind. While the 7,000 watts output is robust, the generator weighs around 270 pounds, which can make it less portable compared to lighter models. Although it has wheels for easier movement, transporting it over rough terrain might still pose a challenge. Additionally, being a higher-end model, the price point can be a concern for budget-conscious buyers.
