I got a Desire HD. I go camping and have multipule devices when any I wanted a all in one. Looking at one of these to charge it up with. 10 in 1 USB Retractable Charger + Car Adapter for iPad on eBay (end time 20-Apr-11 14:15:52 BST) I asked the seller. He don't know, but says it does charge Motorola's, which use the same port as HTC. Would this charge a HD. I heard some say the pins might be different for charging is this true?
