No, we can't! Relatively speaking, the space inside the usb socket is too limited, and the interval between the electrodes is too small. If you connect 220v AC, it may often spark or even short-circuit fault.
And the usb plug socket shell is also made of metal, and the risk of electric shock is also very large if it is connected to 220 volts. usb sockets are usually used for data exchange or 5 volts DC do not use.
Can not, usb socket voltage is 5V DC, 220V will burn electrical appliances.
