Abstract:
A charger comprising:a direct current (DC) converter comprising: a first housing; a first input port positioned on the first housing for receiving an input voltage carried by direct current; a first conversion circuit positioned inside the first housing for transforming the input voltage into a first voltage carried by direct current; a transmission port positioned on the first housing for receiving a second voltage carried by direct current; an output port positioned on the first housing for outputting one voltage of either the first voltage or the second voltage; and a switch connected to the first conversion circuit, the transmission port, and the output port for switching to the first conversion circuit to output the first voltage through the output port or switching to the transmission port to output the second voltage through the output port; and an alternating current (AC) converter comprising: a second housing; a second input port positioned on the second housing for receiving an input voltage carried by alternating current; a second conversion circuit positioned inside the second housing for transforming the input voltage into the second voltage; and a power port, which corresponds to the transmission port of the direct current converter, positioned on the second housing for outputting the second voltage to the transmission port; wherein the first housing and the second housing are capable of engaging with each other so that the power port is connected to the transmission port, and the charger is capable of changing an output voltage of the output port according to operation of the switch.
