Thank you for viewing. I purchased this for disaster preparedness and have kept it in storage. Since I have hardly used it, it is still in good condition. I am moving overseas, so I have decided to sell it. In addition, I am also selling an emergency power supply, AP R600, separately, so please take a look at that as well. 【Product Details】 Allpowers Foldable Solar Panel Charger Model Number: AP-SP-027 〜Generate power anywhere with sunlight〜 ◆DC power and USB power can be used with solar power! ◆For camping, outdoor activities, and as a disaster preparedness item... ◆Convenient for outdoor activities like camping, places without outlets like barns and garages, and during disasters like power outages!! ◆Works great in combination with an MP-3 large-capacity portable power supply during disasters!!
