  Does the charging speed of the mobile phone depend entirely on the output power of the power adapter(图1)

  Do you often feel this way: If you replace the low-power power adapter, it will take a long time for the phone to be fully charged. So, the speed of charging the mobile phone is determined by the power of the power adapter?

  Such a statement is too one-sided. A complete charging process consists of two parts: the charging device and the charging protocol, so the speed of charging the mobile phone is related to the power adapter, data cable, and charging protocol. Now Flying Eagle will briefly introduce to you. The function of the power adapter is to convert 220V alternating current into direct current suitable for mobile phones. If there are no other factors, the greater the output voltage and current of the adapter, the faster the charging speed of the mobile phone. The function of the data line is to be responsible for the transmission of current, and it also has a certain influence on the magnitude of the current. For example, the output current of the power adapter is 3A, but if the data cable is too long or too thin, the actual current transmitted will also be less than 3A.

  In the era of button mobile phones, the default charging protocol of most mobile phones is USB2.0, the charging power is 2.5W, and the charging speed is not fast. However, with the increasing capacity of mobile phone batteries, this charging protocol can no longer meet people's needs. Yes, various mobile phone manufacturers have redefined charging identification standards and pushed various fast charging protocols. For example: Huawei's FCP protocol, OPPO's VOOC protocol, VIVO's SFC protocol, and of course PD and QC protocols that are compatible with most mobile phones for fast charging.

  Therefore, the charging power of the power adapter is not the only factor that determines the charging speed of the mobile phone. It is related to the data cable and the charging protocol.
