I can't believe that this is another USB power supply!

$I can\$

This was inspired by some (read: a lot) tutorials about "How to charge * on USB power", so I reversed the logic and I'm publishing "How to connect *'s charger to USB ports".

As an "added bonus", you can either use the 2 USB ports only with power capabilities...
... or you can connect them to your PC and use them for both power and data transfer.

I already did this kind of thing with a charger to make it so I can charge my iPod from a wall outlet. Kinda unstable, but it works. Tested it in science class (we were watching a movie, and the lab desks have wall plugs!) and I was able to revive my iPod touch from dead to 3/4-charge. I tested it at school because everything gets very hot and I didn't want to burn my house down (I think I need to add a resistor or two).
