Micro usb charger cable manufacturers said that in theory, the length and material of the charging cable will affect the charging speed, but in fact, the charging speed is mainly affected by the material of the charging cable and the size of the cross-sectional area of ​​the charging cable (the thickness of the wire).

Micro usb charger cable manufacturers said that the length of the charging cable does theoretically affect the charging speed. In theory, the shorter the length of the charging cable, the smaller the loss of the wire. The longer the length of the charging cable, the greater its resistance and the slower the charging speed. On the contrary, the shorter the data cable, the higher its resistance. The smaller it is, the faster it will charge. Micro usb charger cable manufacturers found that in practical applications, the length of the charging cable has little effect on the charging speed, so small that it can be ignored.
Micro usb charger cable manufacturers believe that the material and thickness of the charging cable are the main factors affecting the charging speed. The thicker the wire, the faster the charging speed, and the better the material, the faster the charging.
Micro usb charger cable manufacturers give an example: regular charging cables with fast charging speed are generally made of pure copper, and the wires are relatively thick, while those cheap charging cables with slow charging speeds on the Internet are alloy wires with other impurities, the wire is relatively thin.
Micro usb charger cable manufacturers said that there are many factors that affect the charging speed of mobile phones. In addition to the material and length of the wire, there are also the charging head and whether the mobile phone system and the fast charging solution are suitable.
