I know that USB no matter where it connects to will give you 5volts, however if you connect it to a car, your charger will still be 5volts with a certain amperage based on the charger, my question is does the Amp's matter for instance my cell phone's mini USB AC adapter for the home says 5volts but 1A, and I have a mini USB car charger that's for another piece of electronics that says 5volts 2amps. I then also have a Zune in car charger n FM transmitter kit that regulates 5 volts 1.5A. Question is does the amps regulate per device, because Voltage = current * resistance, so I'm assume each item has a different resistance therefore it wouldn't matter?
