I bought this cord for use on the iPhone charger, original cord plugged into ignoring the Iphone. The cord plugs into the iPhone well but can not be loaded. I do not understand that in the evaluation sheet filled there I said "for Iphone 4S" when it was not specified when purchasing. The delivery time was more than a month I guess the seller was out of stock and its replenishment does not match what I ordered. Very poor service and product definition and delivery.
