Only place I could find out what the htc pogo pins +/- are ! Thank you so much and great charging dock you made. I dont know why HTC didn't have a dock for it, would have saved my usb port from much abuse. Maybe a car gps dock could work also, not sure..
But Now that you know the polarity of the pins, you could install a wireless charging pad to it! As some have done on their htc one. Thanks again.
