PD Fast charge pd Fast charge is a fast charging specification developed by the USB-IF organization, and is one of the mainstream fast charge protocols.
The USB-PD fast charging protocol is output by the Type-C interface, but it cannot be said that the Type-C interface must support the USB-PD protocol fast charging.
A charging method that can make the battery reach or approach the fully charged state within 1 to 2h. It is often used for charging traction batteries when they need to be restored to a fully charged state in a relatively short time. In the past two years, many of the new mobile phones we have seen support fast charging, and each brand, Huawei, Xiaomi, oppo, etc., have promoted their own unique fast charging methods. Finally, it can be said that there are only two fast charging methods: PD and QC.
Moreover, QC can also be said to be a branch of PD. The charger that supports PD can charge the phone that supports QC, while the charger that supports QC cannot charge the phone that supports PD.
