The charging head network has also tested the Mate 20 Pro equipped with a 40W SCP fast charge.Mobile phoneIt takes only half an hour to charge the battery from 0% to 70%, which is really shocking. In addition, this mobile power supply also added the USB PD fast charge function, which can directly charge the notebook. Li Xiaolong, vice president of Huawei's mobile phone product line, broke the news through Weibo.
The charging head network placed Huawei's 40W super fast charging mobile power supply in the first time. The following will bring you the disassembly of this Huawei 40W super fast charging mobile power supply.
First, Huawei 40W super fast charging mobile power appearance
Huawei's 40W SCP mobile power box is based on white, black, and red Huawei logo, with plastic hooks designed to facilitate offline sales. The front of the shell is printed with a real picture with the words "Huawei 12000 40W SuperCharge multi-protocol bi-directional super fast charging mobile power" and "Huawei logo," printed on the bottom of the physical map "40W bi-directional super fast charge" and "multi-protocol full compatibility." "German T ü V Safety Certification" three major product features.

Summary of the charging head network disassembly
Huawei's 40W super fast charging mobile power supply adopts a minimalist design, but the workmanship is first-class, the body is light and thin, and the hand feel is very good. The measured can support FCP, SCP, USB PD, QC3.0/2.0 and other fast charging protocols. Support Huawei Mate20 Pro to achieve 40W super fast charge, and quickly charge Huawei Mate 20, MacBook Pro, iPhone X and other devices.
The charging head network dismantling found that this product uses three ATL batteries in series design, the battery terminal voltage is relatively high, the current on the circuit board is smaller, the efficiency is guaranteed, and the heat generation can be effectively controlled. At the same time, RICHTEK fully integrated buck-boost controller is integrated with PD and fast charge protocol. The peripheral only needs to be equipped with switch tube and inductor components to form a complete PD mobile power supply. In addition, the mobile power supply has built-in TI battery protection chip and temperature detection to provide better protection for the battery; temperature sensors are arranged near the interface and power components to monitor the heat generated under high current and protect the mobile power.
