Determinants of mobile phone charging speed

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 line.

Tell everyone the answer: it has a relationship with the charging head and also with the data line. What is the specific relationship? How to choose when one of them is broken?

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 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 line also affect the charging speed?

       
The data line 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 lines 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 line also has a certain impact on the charging speed, and the shorter the data line, 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 lines of different lengths in different usage scenarios. For example, charging a mobile phone with a charging treasure, it is recommended to select a short-term, in the hands of the line is not too long, the charging speed is also faster.

       
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 line, it is more convenient to use.

Of course, in addition to the above mentioned, the quality of the charging head and the data line also has an effect on the charging speed. It is recommended that you choose the original or big brand as much as possible, and the quality is guaranteed.
