10 Best Quiet Generators 2025 in the United States

The Jackery Solar Generator 300 is a lightweight and quiet portable power source perfect for camping, outdoor activities, and emergency backup. It runs on a 293Wh lithium-ion battery, avoiding gasoline and fumes, which means no engine noise or maintenance. With a pure sine wave inverter, it delivers stable and clean 300W power through two AC outlets, suitable for charging small devices such as laptops, cameras, drones, and phones.

Recharging is flexible — you can charge it quickly in about 2 hours using a wall outlet and USB-C port together, or use the optional Jackery SolarSaga 100W solar panel to recharge off-grid, which is great for longer trips but note the panel is sold separately. The unit weighs just over 7 pounds, making it very portable for hiking or travel.

Its 300-watt output limits it from running high-power appliances that need more juice, so it’s not ideal for heavy-duty generator needs. Also, the battery capacity means it won’t power devices for very long without recharging. This generator is a quiet, clean, and portable power solution for light use outdoors, but users needing longer run times or higher power should consider larger models.

The Generac 12,500 Starting Watt Tri-Fuel Portable Generator is a versatile and powerful option for those needing steady backup power at home, on job sites, or for RV use. Its standout feature is the ability to run on three types of fuel—gasoline, propane, or natural gas—which provides flexibility and extended use during outages or remote jobs. The electric start facilitates easy operation without manual effort, and the built-in CO sensor monitors carbon monoxide levels for added safety. With a starting wattage of 12,500 and running wattage of 9,500, it effectively handles heavy-duty appliances and tools.

The fuel tank supports up to 9.5 hours of runtime at half load, allowing longer use without frequent refueling. Portability is enhanced with heavy-duty never-flat wheels and a sturdy frame; however, weighing 219 pounds, it requires some effort to move around. Although it is promoted as quiet, this generator may produce more noise compared to inverter-specific models which are designed for minimal sound.

This model does not incorporate inverter technology, so its power output might be less stable for sensitive electronics. For those seeking a durable, multi-fuel generator with significant power and respectable runtime, this unit offers a strong option, provided users are prepared for its size and the possibility of louder operation relative to quieter inverter generators.

The Jackery Solar Generator 4000 Kit is a powerful and quiet solar generator designed for users who need reliable off-grid or backup power, such as RV campers, outdoor adventurers, or homeowners facing emergencies. It offers a substantial 4,085 Wh battery capacity with a 3,000 W power output, enough to run heavy devices like air conditioners and various household appliances. The generator uses clean solar energy, making it fuel-free and eco-friendly, and it supports very fast charging — reaching 80% battery in about 1.3 hours via AC or 1.6 hours with solar panels. Noise is notably low at just 30 decibels, which is quieter than a whisper and ideal for peaceful environments.

One of the key strengths is its expandable battery system, allowing users to increase capacity up to 24 kWh and output up to 6,000 W by linking multiple units, which is excellent for larger power demands. The built-in lithium iron phosphate (LiFePO4) battery technology enhances safety, durability, and lifespan, with up to 10 years of use and protections against overheating and shocks. It also features inverter technology that ensures stable and clean power suitable for sensitive electronics.

Portability is somewhat limited due to its weight of over 140 pounds, making it less convenient for frequent transport or solo users. While solar charging is an excellent feature, the need for multiple panels to optimize charge speed means additional setup and investment. The product ships in multiple pieces, which might require some assembly. This generator is ideal for those who prioritize quiet operation, large power capacity, and clean energy use over lightweight portability, making it a strong choice for home backup, RV use, and extended outdoor trips where reliable, quiet, and expandable power is needed.
