Choose the cable of the data cable for the mobile phone charging cable

First of all, the data line is divided into two parts, the internal "wire" and the external "insulation".

According to the principle of junior high school physics: when the current is constant, the thicker the wire, the greater the current that can pass, and the faster the charging will naturally be!

Therefore, as the internal material of the conductor, the thicker the better!

At the same time, a good quality data cable will also add a layer of aluminum foil shielding layer and metal woven mesh to make the charging and transmission process more stable. Therefore, a good data line will be thicker.

However, it is not ruled out that some extremely conscientious merchants will deliberately "disguise" their data lines-two data lines of the same thickness, it is possible that the insulation of the data line A is very thin, but the wires inside are very thick and conscientious ; The quality of the internal wire of the B data cable is actually very poor, but the insulation is made very thick.

Therefore, it can only be said that a good data line will not be too thin; and a data line that is too thin will definitely not be good.
