Agreed. The use of fast charging car charger and fast charging data cable can solve the problem of slow car USB charging.
Car charger, in fact, its principle is very simple, is to convert the 12V voltage of the car into 5V, qualified car charger has done overcharge protection in advance. This thing can not covet small cheap, poor quality to resolutely resist, maybe there will be car spontaneous combustion. The quality of the car charger of the big brand is guaranteed, and the output current should be above 1A. The voltage of the general car is 12V, and the voltage of the truck is 24V. The universal type refers to the majority of 12V.
Car USB can not be connected to the fast charge, which is with the USB properties have these relationships. The USB interface of the vehicle, its main function is to provide external hardware devices. USB signals are used to transmit data to each other. It can also provide audio signals and play music through accessories such as U disk and memory card. His electrical signal pressure is only a few amps, so it can't reach the level of fast charge.
No way. Car wired USB phone charging does not support fast charging.
