At first glance, it may just look like a plain old disposable coffee cup. But look again and you'll see a thin solar panel attached to one side and a USB cord. Meet, "Mr. Buzz."
Created by James Long (a.k.a: the "Gadget Gangster") on the DIY site Instructables, Mr. Buzz harnesses the rays of the sun to power devices and charge its 2400mA battery pack. It can charge just about any electronic device with a 'Type A' USB jack (i.e.: many cell phones, MP3 players, hand-held gaming systems, etc.). And when the sun isn't out, the rechargeable batteries can hold 2,500 milliamps — enough power to fully charge an iPhone or similar device twice.
