Is the fast charging of mobile phone related to the head or the line?

Mainly the head, the so-called fast charging is the design of the charger head. However, threads are also related. Even the old wire used in the past can't achieve real fast charging, because the wire is thin and the good wire is thick. The thickness mentioned here is not the appearance, but the thickness of the copper wire inside. Anyway, whether the charging is fast or not depends mainly on whether the output power of the watch is high enough, and then it is the original one. If it is original, it can be charged faster. If you want to buy that charging head again, you'd better buy the original one. It's better for mobile phones. Anyway, the fast charging of mobile phones has something to do with falling.
