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.
Charges your phone's battery to 100 percent in 0.7 seconds!
Meatpuppet submitted with comment: Out of state and forgot the camera charger. One cell phone charger, two paper clips, two pieces of a stir straw and we are in business!

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!
Troll science at its finest.
