10 Best Solar Generators 2025 in the United States

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.

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.
