In theory, the USB charging cable only uses two wires for power supply (VBus) and ground (GND), and does not involve data transmission, so basically the USB charging cables are similar. For better wires, there are more copper wires in the core, but for lesser wires, there are very few copper wires in the core, even I have seen only one or two wires. If the quality of the core is poor, it will definitely affect the charging, especially now that the output current is more than 2A, the resistance of the poor quality line will be larger, and there is a risk of overheating and fire, and the poor line charging speed It will be slower.
