Huawei Mate9 is a mobile phone released by Huawei in October 2016. At the same time, Huawei also released a charging technology called Huawei Super Charge (SCP).
Different from the traditional 9V, 12V high-voltage fast charge technology, Huawei SCP super fast charge charging specifications are 5V/4.5A, 4.5V/5A, also called low-voltage high-current direct charge. The fast charging system is composed of a mobile phone power management chip, a charging line and a charger.
The biggest advantage of this type of charging technology is to reduce the heat generated when the phone is charging. The heat is directly dissipated, so that the low-voltage and large-current are rapidly charged, and the heat generated by the mobile phone body has a considerable advantage, so that the low-voltage and large-current are more in line with the consumer’s concept.
Huawei SCP super fast charging power is up to 22.5W, so the wire and charger have been improved, the metal contacts have been widened, the wires have been thickened, and the ordinary Type-C line cannot be used for super fast charging. From the USB head, you can see a few gold-plated and strong contact points inside, and the core is purple.
The Type-C charging cable that comes standard with Huawei phones is printed with 5A. It is specifically stated that this line can pass 5A high current.
In addition to optimizing the fast charge on the hardware, Huawei engineers also hinted on the type of charging in the EMUI system. The charging icon can be displayed according to different charging types.
A total of 13 mobile phones supporting Huawei SCP fast charging and USB-C interface. In addition to Huawei’s official 5A line, there are also many brands selling Type-C lines that support 5A.
