How many lines are there inside the data line?

Data cable is the usual charging cable, which is composed of four cables. Here also needs a simple explanation, now fast charge is very popular, some support large current 5A wire it will have five wires inside.

On the Internet and some of the data lines sold for a few dollars a piece, it has only four cables inside, and these data lines are not shielded. Only the original data cable of mobile phone and high-quality data cable of big brand will have metal shielding layer and tensile fiber wire inside.

The red line is the positive power supply pole, the black line is the negative power supply pole, the green line is the positive data transmission pole, and the white line is the negative data transmission pole. In general, because the green and white wires do not supply power, they are thinner than the positive and negative wires!

Note: There will be two red wires inside the current high current (such as 5A) wire, both of which are positive wires, and the negative wire is a wire without any colored layer wrapping. The green and white wires are also data transmission lines!

Only the red and black wires are used in daily charging of the phone. The green and white wires are only used when a phone is plugged into a computer or other device to transmit data to and from each other.
