The data line is used to connect mobile devices and computers to achieve data transmission or communication purposes. In layman's terms, it is an access tool that connects to a computer to transfer pictures and other files. In addition, the data cable can not only achieve the purpose of transferring files, but also can be used for charging. Now with the rapid development of the electronics industry, the data cable has become an indispensable part of our lives. However, many people encounter a problem when using data cables to charge. Why do some data cables charge so slowly? Is there any solution? Next, let’s introduce one or two.
Because the power of each data line is different, the high-power one of the same mobile phone will be fully charged quickly, and the low-power one will take longer. In addition, the charging speed has nothing to do with the structure, but is related to the resistance. The original data cable is usually 0.4~0.5 ohms, while most cheap cables are 1~3 ohms, so it is easy to cause slow charging. However, all USB data lines look the same, but the amperage provided by them is different, and this important information is never marked on the data line.
At this point, there may be a variety of different USB data cables in one of your drawers. It is difficult to distinguish which data line serves which device, although all data lines look the same, they can be very different if they are used in different places.
