When buying an Android phone, general accessories will have a data cable, and the data cable can be used as a charging cable. We all know that. But can the charging cable be used as a data cable? What is the difference between a charging cable and a data cable? Let's take a look.
Generally, our data cable and charging cable use the USB interface. Generally, there are four cables. When the charging cable is used, the two cables of VCC and GND of the power supply are used, and the data cable uses VCC, GND, and two communication cables..
The data cable has four lines in the cable of the USB interface, and the power cable has two lines in the USB cable, so the data cable can be used as a power cable, but the power cable cannot be used as a data cable.
The wire inside the data cable is very thin, and the different wires have different resistances. The current is different, and the current is large and fast to charge, otherwise it is slow. Generally, the original charger is fast, but the non-brand one bought in the repair shop is very thin, and the charging is slow.
