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.
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!
