Long story short I'm hardwiring my droid in the car, so I can have it mounted high up on the windshield and also charge it at the same time. I basically cut the end off a walmart home charger, pretty simple really....BUT the damn charger has a green wire and a black wire....most would assume that black is ground...NOPE...so I fried my phone to where it won't charge anymore. I'm getting a replacement phone so not a big deal but here's the question. When I hook up the new phone (with the wires having been corrected) is there any reason to think that 12 volts straight to the phone would cause any further problems. So are there any smart folks out there that can confirm 12 volts is the correct voltage to charge a droid..........versus perhaps there's something special inside the car charger / home charger like a resistor to change the voltage?
