our dog destroyed my rezound's charging cable. I purchased a new HTC charger and cable from CCM Accessories on Amazon.
CCM sells genuine HTC accessories whereas other sellers on the same amazon webpage sell cheaper Chinese knockoffs. This is why the reviews vary so much for the same product.
Amazon.com: OEM HTC USB Travel Charger Adapter U250 / CNR6300 / 79H00095-14M: Cell Phones & Accessories
On the full screen website one click on New and see all the sellers of the item.
For 8.99 with free shipping from CCM, it is good.
The charger is the exact same part number as the rezound charger with 1 amp output at 5 volts.
The cable is not identical, it is standard microUSB, but appears to be made by HTC, but for a different HTC phone. the wire is thick but can not be absolutely certain it is made by HTC. it had a HTC sticker thing around the wire.
It seems to work ok.
So in case anyone else has a similar need....
