10 Best Solar Generators 2025 in the United States

The Jackery Solar Generator 1000 v2 is a solid choice if you need a portable power source for camping, RV trips, or emergency backup. It offers a large 1070Wh LiFePO4 battery, which is durable and has a long lifespan—rated for about 4,000 cycles while maintaining most of its capacity. The 1500W continuous AC output (with a 3000W surge) is strong enough to power many home essentials like fridges or small AC units. It includes versatile ports, including 2 USB-C ports with fast charging, so it can handle multiple devices at once.

A standout feature is its fast charging capability—it can fully recharge in around 1 hour, which is much quicker than many competitors. The generator supports charging via two 100W solar panels included in the package, making it suitable for off-grid solar use. Its compact size and 23.8-pound weight with a convenient handle make it fairly portable, though it’s on the heavier side compared to smaller models.

The unit uses a pure sine wave inverter, which ensures clean and stable power safe for sensitive electronics. It also offers smart app control for monitoring and managing power use, including quiet operation modes. Build quality is solid with ABS material and protective certifications, promoting safety and durability. The runtime at full load is under an hour (42 minutes), so for heavy power users, it won’t last very long without recharging. While the fast charge is impressive, it requires compatible chargers and infrastructure to reach the 1-hour speed. The price point tends to be on the higher side, reflecting its premium features. This generator is well-suited for those seeking a robust, fast-charging solar generator with good capacity and multiple outputs for camping or emergencies. If you need longer runtime under heavy load or a lighter unit, you might consider other options.

The EF ECOFLOW Solar Generator DELTA2 is a robust solution for those seeking clean and portable power, perfect for camping, RVs, or as a backup at home. One of its standout features is the impressive 1800W output, which allows it to power most household appliances without any emissions or noise, making it a great alternative to traditional generators. Its LFP battery offers a significant lifespan of over 3000 charge cycles, which means this unit will last for years with proper care. The ability to expand its capacity from 1kWh to 3kWh by adding extra batteries is a great plus for users with greater power needs.

Portability is another strong point, as the DELTA2 and its 220W bifacial solar panel are designed to be mobile, making them suitable for outdoor activities. The solar panel's ability to capture up to 25% more energy thanks to its bifacial design enhances its efficiency significantly.

The EF ECOFLOW Solar Generator DELTA2 is an excellent choice for individuals or families who need reliable, eco-friendly power for outdoor adventures or backup during outages.

The Jackery Solar Generator 300 is a reliable and portable power station suitable for outdoor activities like camping and road trips. With a battery capacity of 293Wh, it provides a decent amount of power for small devices and electronics. The 300W pure sine wave AC outlets ensure a stable and safe power supply, which is great for sensitive devices. Its compatibility with the Jackery SolarSaga 100 solar panel allows for green energy recharging, making it ideal for off-grid use.

The generator can be recharged through multiple options, including wall outlets, car outlets, and solar panels, which adds to its versatility. Weighing only 7.1 pounds, it’s quite portable and easy to carry around. The device features multiple ports, including USB-C, USB-A, and DC car port, allowing simultaneous charging of up to six devices.

However, its relatively low power output of 300W means it may struggle with high-power appliances. The build quality is solid, but it's primarily made of plastic, which might not withstand extremely rough handling. Additionally, it is important to note that the solar panel and generator are shipped separately, which may cause inconvenience. It is a great option for those looking for a portable and eco-friendly power solution, although users needing higher power output or more rugged durability might find it less suitable.
