The Rubik's cube that can charge your phone

If you like to pass the time idly playing with a Rubik's cube, you might as well have it do something constructive. The Magic Charger is essentially a fancy Rubik's cube with a small manual electric battery inside. As you twist the cube around, it charges up. You can then plug in any USB device to juice up when you're done playing.

Of course, it's not really clear if this concept device is an actual Rubik's cube or just a similarly-shaped object that you just twist over and over again. We've seen stuff like that before. But if this is really a classic puzzle game that can charge your phone, sign us up.
