In the era of fast charging, our charging habits are quietly changing, and more and more friends will choose a phone that supports fast charging. At present, the vast majority of chargers for mobile phones and charging devices are A-port outputs, while PDs require TypeC interfaces. PD is a fast charging protocol, while Type-C is a new interface specification. The Type-C interface supports a maximum of 5V/3A by default, but after implementing the USB PD protocol, it can support an output power of up to 100W. Enable all mobile phone users to better enjoy fast charging technology, making it convenient for everyone to use.
