The ebay ones are most likely fakes like all their "HTC original charger" so i would no clue sorry for the waste of a post thought i should tell you that.
maybe instores? but like a generic lg charger?
A Charger is a charger, or I should say the cable is.. The cable is the same, but the dongle is rated for certain voltage. MCS-Q1WR not sure if that is the model # but any 5v should be the same.
