HOW TO: Install a Charging USB Port on your Bike!!!! ZOMG!!
The iPhone sucks up more wattage when charging than that connection is going to provide. It's the same reason you can't use junky chinese USB chargers with it, you have to by the expensive ones that up the capacitance. That's right: wiring your iPhone directly to a car battery still doesn't provide enough power. Honestly, this mod bareley provides enough for my Pre, but it works, so it's great in an emergency.
