Functions:
1.Audio input and output(Listen to music, voice and call);
2.Charging( normal-5V*1A and fast-5V*2A); 3.Completely wire control;
2.Charging( normal-5V*1A and fast-5V*2A); 3.Completely wire control;
4.Data transmission-we suggest cancelling this function, as it will affect the stability of product, the main factor is signal interference. Moreover,data transmission is not a necessary to adapter, we should do substraction to meet basic requirement, not do addition to make function superposition.
