How to choose the charging cable of 20W PD power adapter?

As the saying goes, a good horse comes with a good saddle. After getting the iPhone 12, if you want to charge it stably and safely, you need to be equipped with a high-quality 20W power adapter and a good cable. But many people choose the power cord only to see if it looks good, but they don't know how to judge the quality.
Because of the iPhone 12, many people are buying 20W PD charging heads. Although there is a free data cable in the library, most people will buy an extra spare. In the process of purchasing, it is generally believed that a thicker cable is better. In fact, it is not the case. The real good wire is insulated, and the inside of the wire is divided into several wires. The more wires, the faster the charging speed. That is to say, it will cause your mobile phone and computer to fail to connect during data transmission.
First of all, a good brand of data cable will not put fancy packaging as the first priority of the product, so good-looking is not necessarily easy to use. Secondly, take out the cable and look carefully. For a good-quality data cable, the cable must be relatively soft and feel tough. Not only the cable, but also the interface with the 20W PD power adapter and the charging interface of the mobile phone must be processed. It is very smooth and careful, and a good-quality line must have a trademark at the interface with the mobile phone. Although it is small, it must be very finely made.
