It charges a little faster.
Under normal circumstances, the role of the charging head is larger for the charging speed of the mobile phone. But the role of the data line can not be ignored. The fast charging cable generally uses 7 cores, while the ordinary data cable is 5 cores, relatively speaking, the original 7-core data cable is faster than the ordinary 5-core data cable.
Therefore, the use of fast\/flash charging data cable and ordinary charging head, in general, there is no problem. However, on the contrary, the use of ordinary data cable and fast charge\/flash charging head may cause the charging speed to decrease and so on. Therefore, if conditions permit, it is best to use the original charging head and data cable.
