Do the length and material of the charging cable affect the charging speed?

Theoretically, the length and material of the charging cable will affect the charging speed, but in practical experience, 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).

The length of the charging cable does theoretically affect charging speed. Theoretically, the shorter the length of the data line, the smaller the loss of the wire, the longer the length of the data line, the greater its resistance, the same charging speed will be slower, on the contrary, the shorter the data line, the smaller its resistance, the faster the charging speed will be. However, in practice, the length of the data cable has little effect on the charging speed, which can be ignored.

The material and thickness of the charging wire are the main hardware factors that affect the charging speed. The thicker the wire, the faster the charging speed, and the better the material, the faster the charging speed.

For example, the normal charging wire wire with faster charging speed is generally pure copper, wire is thicker, and the cheap shanzhai charging wire with slow charging speed is the alloy wire with other impurities, wire is thinner.

Of course, there are many factors that affect the charging speed of mobile phones, in addition to the unexpected material and length of the wire, as well as the charging head and whether the mobile phone system and fast charging scheme are suitable.

It is better to use the original charger to charge, which is the guarantee of charging speed and safety.
