It does not have a battery, so it will not charge. It charges batteries of other devices (batteries) or other batteries. For example, you use it to charge a battery pack during the day. When the sun goes down you connect the battery it charged to charge something, like a cell phone, to charge it up. You can also charge a phone (battery) with it while it is in the sunlight.

Question for the manufacturer. Thin film solar panels are made by other manufacturers. This is the kind of solar panel the average person could afford. Check out "Allpower 100-watt portable, folding solar panel" for backpacking with power bank.

Yes, even when it is cloudy, it works, though never as well as in direct sunlight. I used it for 2 weeks on a Philmont trip, and it kept my devices charged. I still recommend a power bank instead of a direct connection. They just work better. I changed up the power bank, and it provided all the power to the rest of my devices.
