Car Charger Issues

[ott]

Here is a quick question to ask everyone, I had a customer come in complaining his car charger hasn't worked for him, so I tested the charger and sure enough, nothing. I proceeded to try a brand new charger and did this 4 times and none worked! The real kicker is the phone charges completely fine with the home chargers! I tried all of the car chargers on another diamond and they all worked. So why would his phone charge fine on a home charger but not a car charger? The port is fine and the car chargers work with other diamonds? Freaky...
