I have read on this forum that people have problems with their phones if they don't get the right charger so I went to the Verizon store to get an official Droid X car charger. They didn't have such a thing. They wanted to sell me a universal usb car charger. I went to the Motorola site and find that Motorola does market a Motorola branded usb car charger. Has anyone here used either of these? Any problems? Thanks.
