All four USBs support fast charge protocol, and all output 5V 9V 12V voltage.

The USB output voltage depends on your device. The output voltage of different devices is different. The conventional USB output voltage is 5V. It can output different fast charging voltages following the QC protocol. The general fast charging voltage of mobile phones is 9V 12V, and some devices support 5V high current fast charging. , Low-current charging for devices that do not support fast char
