A:AnswerThe key here is the cable is MFi (Made for Apple) certified. This means it was made to specs provided by Apple and should be fine. In reading about the issue it not so much the cable as the charger you use. I would stick with Apple chargers which do a better job of regulating the voltage to the phone and prevents damage to the IC2 chip.
