The Window Cling Solar Charger works just like your regular outlet charger, but it adheres to your window instead of going into a socket. The little device can charge all types of smartphones like the iPhone, Blackberry or Android. Next time your out, and everyone’s fighting over the outlet to charge their phone, you can be smart (and green) by sticking your solar charger to the window and powering up.
