concern
The charging speed of mobile phones is generally affected by three aspects.
1. Thickness of data cable
The wire in the data cable will directly affect the speed of charging, and the data cable generally has 4 wires for power supply and data transmission. In general, the thicker the wire can carry the greater the current, the faster the charge.
2. Length of data cable
In order not to affect the use of charging, many people hope that the longer the data line, the better, especially when lying in bed charging, the longer the data line seems more convenient. But the speed of charging is also related to the length of the data line, because the wire itself will produce resistance, in general, the same quality, the same thickness of the data line, the shorter the length of the data line, the smaller the loss of power, the faster the charging speed.
3. Data cable interface
The same quality of the data cable interface, the tightness of the jack and the material of the interface, these factors will also affect the charging speed of the phone
The speed of mobile phone charging is related to the charging head and the data cable, and there are many reasons for determining the speed of mobile phone charging: the maximum overcurrent and voltage of the wire, the maximum power and standard of the mobile phone charging IC, and the output power of the charging head.

The data cable is responsible for connecting the phone and the charging head, which is mainly responsible for current transmission, so it will also affect the charging speed.
For example, the phone's electricity is equivalent to a bucket, the charging head is a faucet, the data line is a water pipe, to fully charge the phone is equivalent to filling the bucket with water.

At present, the Micro usb interface cable on the market can generally transmit the current of 2A, but there are also some charging cables without signal core wires, which can only be charged and cannot transmit data, and the current supported by transmission is only 500mA, which needs attention when choosing. It is very influential to use
