From the submitter:
I was traveling in China for 2 weeks, and had brought a spare camera battery, but no charger. Borrowed a friend's charger, found some wire, and voila.
Troll science at its finest.
Plug it in, plug it in, plug it in, plug it in, plug it in, plug it in...
Charging the bananaphone, perhaps?
User themna was at the airport and forgot their plug-in phone charger. A little bit of wire, an iPhone charge adapter, and a PSP charger....Voila! Phone is charged!
