The cause of the incident comes from an article by Weibo in Charging Headnet. At that time, when testing Huawei's 40W dual-channel super fast charging mobile power supply, it was found that Huawei P30 Pro could normally use the USB-C interface of the super flash charging mobile power supply to turn on the 40W SCP fast charging. Huawei Mate 20Pro still cannot use USB-C interface to turn on 40W SCP flash charging.
Then the next day, I upgraded the firmware of Huawei mate20 Pro, and then successfully started the 40W SCP fast charging by using the USB-C interface of Huawei 40W super flash charging mobile power supply.
However, I didn't stop exploring. Since Huawei mobile phone can shake hands with 40W SCP fast charging through USB-C interface, can it shake hands with SCP fast charging protocol through USB-C interface of other mobile power supplies? In order to answer this question, I did the following test.
First, the mobile phone part.
Firstly, Huawei Mate30, Huawei Mate20, Huawei P30 Pro and Huawei P20 Pro are selected as test objects.
Then upgrade the system versions of the four mobile phones to the latest system version above 10 to test the charging situation of the mobile phones.
Second, the detailed explanation of Huawei scp fast charging protocol
Detailed explanation of Huawei scp fast charging protocol _ Can USB-C mobile power supply supporting SCP provide fast charging for Huawei mobile phones? The answer is here. ...

Firstly, Huawei Mate30, Huawei Mate20, Huawei P30 Pro and Huawei P20 Pro are selected as test objects.
Then upgrade the system versions of the four mobile phones to the latest system version above 10 to test the charging situation of the mobile phones.
Second, the mobile power supply part
Of course, the test object is the mobile power supply. I found five mobile power supplies to test the charging of Huawei series mobile phones. They are Huawei dual-channel super flash charging mobile power supply, Bess 22.5W fast charging mobile power supply, Lvlian dual-channel fast charging mobile power supply, Senshi pulse energy storage power supply and Yubo 99Wh fast charging mobile power supply.
In order to test, first of all, participants need to meet the test conditions. POWER-Z KT00 1 is used to test the USB-C interface of Huawei's bidirectional flash charging mobile power supply, and supports fast charging protocols such as Apple2.4A, QC, FCP, SCP and 40W SCP.
Next, the USB-C interface of Bess mobile power supply is tested, and it is found that it supports fast charging protocols such as PD, Apple2.4A, QC, AFC, FCP and SCP.
The USB-C interface of Lvlian mobile power supply is tested for fast charging protocol. From the display screen of the test bench, it can be seen that it supports Apple2.4A, QC, AFC, FCP, SCP and other fast charging protocols.
The USB-C interface of Sen's pulse energy storage power supply is tested, and it is found that it supports Apple2.4A, QC, AFC, FCP, SCP and other fast charging protocols.
The USB-C interface of Yubo 99Wh mobile power supply is tested, and it is found that it supports many fast charging protocols such as Apple2.4A, QC, AFC, FCP and SCP.
The data lines participating in the test are dual USB-C data lines with built-in E-Marker chip, which supports 20V 5A 100W power.
Fourth, the test part
