What is a good USB cable
What is a good USB cable?
First of all, in terms of wire materials, the better the data cable, the thicker the inner wire, which can pass a larger current, and there will also be an aluminum foil shielding layer and a metal braided mesh to ensure stability.
Secondly, in terms of length, we often hope that the data line is long enough, but the longer the data line, the greater the line resistance and the more current consumption, so the shorter the data line, the higher the charging efficiency, and the bit errors caused by line noise The rate will be lower.
Once again on the interface, a good data cable will have a thicker gold layer on the contacts, which can improve stability and life, but has nothing to do with charging efficiency.
In addition, with the increase of devices around people, the all-in-one data cable is also becoming more and more popular. It can charge micro USB, Type-C, and Lightning devices at the same time, but this type generally does not support data transmission or only one of them. The interface transmits data. In general, the original data cable is preferred, and the third party chooses the thicker and not so long. If there are multiple devices, there are multiple roots or a transfer interface.
