The data cable does not have the difference between fast charge and slow charge, only the power adapter has the difference between fast charge and slow charge. Charging speed mainly depends on whether the charging head is large current, and whether the mobile phone supports fast charging.
There are two general directions to improve the charging speed: one is to increase the voltage, and the other is to increase the current. Increasing the voltage will increase the heat generated during charging, accelerate battery aging and may bring safety risks, so the actual effect is not good. By contrast, raising the current is more realistic. VOOC flash charging technology adopts low voltage and high current mode to ensure the safety of charging process.
Points, because the fast charging data line is not used for slow charging, only through matching can be
