For fast charging, the charging line is differentiated by type, and the fast charging line is somewhat special compared with the ordinary charging line. Android slow charge and fast charge are 5-core cables (charging data), and the ordinary single-charge model is 2-core (charging). When the fast charge is working, the data cable will coordinate the power of the phone chip and the plug, so that the efficiency of the two matches is maximum. Therefore, the charging power of the fast charge depends on the matching degree of the output end (charging plug), the transmission end (charging line), and the receiving end (mobile phone chip). Therefore, choose a fast charge line, to choose a 5-core, rather than a 2-core single-charge type, that is to say, you can not use the kind of charging line that can only be charged. The speed of mobile phone charging mainly depends on the charging head, for consumers, the key parameter of the charging head is the charging power, the power is the most important indicator affecting the charging speed, so change a data line that can be charged, even if it is not the original, the impact on the charging speed is not large. If you choose the data cable, it is recommended to choose the reinforced protection of the charging interface, such a charging cable is not easy to damage, marathon, electric magic two brands are also OK, you can pay attention to it.
Of course depends on the plug, look at the input and output current. Xiaomi and Huawei chargers are good, that is, expensive points, want to buy better points soon. A few dollars, ten dollars of charging head is not reliable.
