We all know that the charging speed of mobile phones is inextricably linked to the phone charger. The charger consists of a charging head and a data cable.
Does the charging speed of the mobile phone depend on the charging head or the data cable? Let me tell you the answer first: it has a relationship with the charging head and has a relationship with the data cable.
What is the relationship between the charging speed and the charging head?
When charging a mobile phone, the charging head determines the magnitude of the voltage and current. The voltage and current output parameters are marked on the regular charging head.
For a very simple example, your phone supports 5V/2.4A, which is 12W charging. If the charging head is broken, you can change the charging speed of the 5V/1A, which is the 5W charging head, and the charging speed will naturally be much slower.
Why does the data cable also affect the charging speed?
The data cable is responsible for connecting the mobile phone to the charging head, which is mainly responsible for current transmission, and therefore also affects the charging speed. At present, the line of Micro usb interface on the market can generally transmit 2A, but there are some charging cables without signal core. It can only be charged and cannot transmit data. The current supported for transmission is only 500mA. Please pay attention when selecting.
In addition, the length of the data cable also has a certain impact on the charging speed, and the shorter the data cable, the faster the charging speed will be. The standard data cable of the general mobile phone is 1 meter. However, we can also match data cables of different lengths in different usage scenarios.
Of course, if you want to lie in bed or on the sofa while playing mobile phone charging, it is not particularly anxious, do not need to consider too much charging time, you can choose 1.5 m or 2 m data cable, it is more convenient to use.
Finally, to sum up, only the charging head and the data cable are selected correctly, the fastest charging speed can be achieved.
