Bought for power outages or camping in the truck when I don't want to lug around my small generator to keep it charged. They are easy to fold and quick to install. Connected to it is a small inverter with multiple USB port outputs. I charged a GOLABS 204Wh portable power station and 3 cell phones in about 4 hours of good sun. The construction of this device is well made using durable Cordura nylon and a plastic frame. In fact, I like it more than other famous branded products I've used in the military. The instructions left a lot to be desired, but nothing that couldn't be found with Google.
