This is why the price of the data cable with the same model function is 2 times worse.This is related to the material of the data line and the match with the mobile phone, whether there is pure copper in the line, or the purity, or the number of copper cores in the data line also affects the number of cores, of course, the transmission of data and charging will be fast, and on the contrary, it will be much slower.Classification from the manufacturer: original original; Domestic brands; Domestic without a license.1, the original original: directly produced by the mobile phone manufacturer, or provide materials commissioned by a manufacturer, marked with the brand of the mobile phone, the best quality, the most expensive.2, domestic brand: the data line has its own brand, in addition, the address and phone number of the manufacturer is printed on the package, which is more formal, good quality and low price, such as Lingkai data line.

Some are fast charging agreements need to be matched with additional chips, if it is Xiaomi, his data line is actually changed by magic and can not be bought on the market is not the same. Although the exterior, you can't see but the inside of the line is different. There are also some charging cables, because the material is relatively cheap, so it does not support the output of large current, so it can not be fast charged.
