Early low-speed charging: 5V × 500A, early ordinary charging: 5V × 1A. Early fast charging: 5V × 2A
The following describes the fast charging protocols of major manufacturers:
    The PD protocol refers to the USB-PD protocol, and its full name is USB power delivery. It is a fast charging protocol proposed by the usb-if organization, which is theoretically up to 100 watts.
