How to identify the charging cable and data cable?

1, function

The charging cable only has a charging function, the data cable is used to transmit data, and the general mobile phone data cable has both charging and transmitting data functions. If you just want to charge your phone, both lines can be used; if you want to use the data, the charging cable does not have this function, you can’t directly implement it.

2, the interface

     
This is easy to understand, the conventional mobile phone data cable is divided into micro, type-c, lightning, mini usb, hdmi five kinds of interfaces, the interface is wrong, its charging cable or data cable , can not be inserted.

So, how to distinguish whether a mobile phone cable is a charging cable or a data cable?

Very simple, the general mobile phone cable interface has a logo, the charging cable is a lightning shape, and the data cable that has both charging and data transmission functions is another symbol. In theory, it is easy to distinguish between the two symbols, whether they are charging cable or data cable .

So in general, the interface can be universal, you mix it all right, but there may be some lack of functionality, such as some wires plugged into the computer can only charge, can not transfer data. Some custom data cable are not available for other phones.

     
Mixing the data cable is fine, but you need to ensure that the data cable you use is a qualified product, and do not use inferior products. Otherwise, the charging rate may be too slow, the transmission data may be lost, and serious dangerous accidents such as fire may occur, which may endanger personal safety.
