Mobile phone fast charging, is it the credit of the mobile phone data cable or the credit of the charging head?
1: How is fast charging achieved?
The speed of charging is determined by the charging power, and charging power = voltage and current, so to achieve fast charging, either increase the voltage or increase the current. These are also the two main forms of fast charging technology currently on the market.
2: The charging head is the protagonist in the fast charging system
The output power of the charging head is the most direct factor affecting the charging speed. If the power of the charging head is not enough, fast charging cannot be achieved.
3: The data line is also crucial
The ordinary charging cable contains 3 wires working, 2 wires are power wires, and the other 1 wire is ground wire. The fast charging cable is basically 5 cables working, in addition to the original 3 cables, 2 power cables are added. The length of the data cable also has a certain impact on the charging speed. The shorter the data cable, the faster the charging speed.
