10 Best Quietest Generators 2025 in the United States

The Jackery Solar Generator 2000 v2 is a strong choice if you're looking for a quiet, portable power source with solar charging capability. It produces up to 2200 watts, enough to run many home backup devices, camping gear, or small business equipment. Its LiFePo4 battery technology promises safety, long life (up to 10 years), and silent operation since it produces no fumes like gas generators. The generator includes 2x200W solar panels for eco-friendly charging, and can also charge quickly via AC power or an emergency super charge mode.

One of its standout features is the very quiet charging mode that operates at just 30 decibels, allowing you to work or sleep without noise disruption. At 39.5 pounds and with a compact design, it’s more portable than many comparable power stations, though it’s still a bit heavy to casually carry for long distances. The 20ms UPS switching ensures your devices won’t lose power during outages, which is great for critical electronics.

The main drawback is the cost and the fact that solar panels may ship separately, which could complicate setup a bit. Also, while it’s quieter than traditional gas generators, it’s not silent since it has fans for cooling. This generator suits those prioritizing clean, quiet power with versatile charging options, especially for home backup or outdoor use where noise level matters.

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 Jackery HomePower 3600 Plus is a powerful portable solar generator designed primarily for home backup, emergencies, and RV use. It delivers a strong 3600W continuous output, which is enough to run common household appliances like heaters and pumps. One of its standout qualities is that it operates on battery power rather than gas, making it much quieter than traditional gas generators — great if noise is a big concern. Battery-powered units like this are generally whisper-quiet, especially when compared to conventional generators. The unit is an inverter type, meaning it provides clean, stable electricity suitable for sensitive electronics.

Its battery capacity is large at 3584Wh, and it can be expanded significantly by connecting multiple units, supporting longer power needs. Charging options are flexible, including AC, solar, and gas generator input, with fast recharge times which add to convenience. Portability is good for its size; it weighs about 77 pounds but is designed with wheels and a handle, making it easier to move around despite being heavier than smaller models. The HomePower 3600 Plus also boasts safety features like a heat-resistant battery to prevent overheating and a long lifespan with thousands of charge cycles.

The weight and size might be a drawback if you need something very lightweight or compact. While it has an eco/quiet mode implied by its battery operation, it lacks explicit load-sensing features that some other generators offer to optimize energy use automatically. This model is ideal for those who want a quiet, clean, and reliable power source for home backup or off-grid use, especially if you plan to use solar panels for charging, and don’t mind the heavier weight for the increased power capacity.
