Keeping my dedicated cell phone charged
I have a samsung a670 phone in my car dedicated to on the fly internet access. Works great when i'm out of wifi range. My only problem is the data cable i have doesnt charge the phone when plugged into the usb port. So you miracle workers tell me what to do here to keep my phone charging. My idea is take the car charger i never use anymore, wire it directly to the ACC line and splice it into the power line from the usb data cable, thus chargine my phone whenever the car is on. Would it be that simple? Usb powers the phone with 5v, this would power the phone with 12v. Is that a problem. And what about the voltage from the car charger traveling back into the computer when its spliced into that 5v line? After frying a couple of usb devices in the past i wanna be sure i know what i'm doin before i partake.
