10 Best Quiet Generators 2025 in the United States

The Westinghouse 12500 Watt Dual Fuel Generator is a solid choice for those looking for a powerful and versatile backup power solution. With running watts of 9500 on gasoline and 8500 on propane, plus peak outputs of 12500 and 11200 respectively, this generator can handle most home appliances during outages. Its dual fuel capability adds flexibility, allowing users to switch between gasoline and propane based on availability or preference.

The generator offers an impressive run time of up to 12 hours on a full tank, which is beneficial for prolonged use without the need for frequent refueling. Portability is decent, as it weighs 210 pounds; while it may not be the lightest generator, it does have built-in handles that assist with moving it around.

On the downside, its weight could make it difficult for some users to transport without help, particularly if you need to move it across a yard or to different locations. Additionally, being a gas-powered generator, it may not be the best fit for those seeking an ultra-quiet option for camping or in highly noise-sensitive areas. The safety features, including rubber covers for the outlets and automatic low oil shutdown, add peace of mind during operation.

The Honda 664240 EU2200i excels in the category of quiet generators with a noise level ranging between 48 to 57 dBA, which is quieter than a normal conversation. This makes it highly suitable for camping, RV use, and residential areas where noise is a concern. The generator delivers a maximum power output of 2200 watts, with a running wattage of 1800 watts, which is sufficient for a variety of appliances and tools, making it versatile for different environments such as home emergency power backup, job sites, and outdoor adventures.

It uses gasoline as fuel, and its Eco-Throttle System ensures impressive fuel efficiency. Depending on the load, it can run for 4.0 to 9.6 hours on a 0.95-gallon tank, offering flexibility for overnight use or prolonged applications. Portability is another strong point, with a weight of 46.5 pounds and compact dimensions (19"L x 12"W x 21"H), making it easy to transport and store. The inverter technology provides stable and clean power, similar to what you would get from a household outlet, which is crucial for sensitive electronics.

However, there are a few considerations. The 2200-watt maximum output, while ample for many uses, may not be sufficient for high-demand appliances or heavy-duty equipment without paralleling an additional unit. Also, its gasoline fuel type may not be ideal for all users, particularly those who prefer renewable energy sources or propane for cleaner burning. Despite these minor drawbacks, the Honda 664240 EU2200i is a reliable and efficient option for anyone needing a quiet and portable generator.

The Generac 18,000-Watt Gas-Powered Portable Generator offers significant power, making it an excellent choice for emergencies, home use, and recreational activities. It features a powerful 816cc engine that ensures efficient performance. A standout safety feature is the COsense Technology, which provides protection against hazardous carbon monoxide, an essential aspect for user safety.

The TruePower Technology is beneficial for safely powering sensitive electronics, with less than 5% Total Harmonic Distortion (THD), making it suitable for residential use. The generator also includes a low-oil pressure shutdown for enhanced engine protection, which contributes to its longevity and reliability.

Additionally, its large fuel tank extends run times, which is great for long-term use without frequent refueling. However, the generator weighs a hefty 442.8 pounds, which may impact its portability, despite being listed as a portable model. This weight might make it challenging to move around without assistance. This generator is best suited for those who need substantial power and advanced safety features, and don't mind the potential noise and weight.
