3 kW Lithium Power System – Power and Reliability in One Unit Complete unit, original packaging, used for less than 4 months only. Ready to go. I used it in the desert for a pressure cooker, projector, and phone chargers. It charges once and lasts me for 4 camping trips. Without the pressure cooker, it lasts me about 8 to 9 camping trips. Honestly, it's great. Its warranty is two years from Al-Ajeeb Al-Ghareeb. There is about a year and a half left on the warranty. If anything happens to it, they will replace it with a new one. Its default battery warranty is ten years. Specifications are in the pictures. Reason for selling: The car has been sold. Selling to the highest bidder.
