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.
But in fact, it’s hard to say, because the cores of USB cables of different qualities are very different. A better line has more copper wires in the core, but a lesser line has very few copper wires in the core. , Even I have seen only one or two roots. If the quality of the core is poor, it will definitely affect the charging, especially if 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.
