Very simple, the car is generally not directly used to charge mobile phone electricity, so you should go to buy a car phone charger. The price is not expensive. All iphones and ipads can do this, but the iphone can charge with USB, but the ipad can't charge with USB. But there's no guarantee that your phone won't malfunction
This will happen if the charging head output current is below 1A, and it will not happen with the original charging head! If there is no original charging head you can use other brands of 5V1A charging head, the charging head output current can not be lower than 1A!
