More and more gadgets are coming that lets you power your devices with solar energy, and now you can even earn points while doing so. A charger from the new German startup called Changers, doesn’t just give you a great power source in the sun, but it also earns you credits that you can use to both compete in green credentials with your friends, and also buy items with.
The charger consists of a solar panel and a battery. It takes about four hours to reach a full charge, and this gives you enough juice to charge an iPhone, twice. It also comes with an array of adapters for devices from the most common manufacturers like Nokia, Sony Ericsson, Samsung, Sony PSP or Nintendo. Anything that charges over USB will basically work.
