Claim Text:
1. A power adapter, comprising: a plug configured to connect to an external power source; an AC to DC converter configured to convert alternating current (AC) from the external power source into direct current (DC); a DC output member configured to output the DC to an external device to power the external device, wherein the DC output member comprises a holding structure, and the holding structure comprises at least one protrusion extending from the holding structure, and the protrusion protruding from the holding structure forms an open end; a first electrical wire configured to electrically connect the AC to DC converter to the plug, the first electrical wire comprising a first terminal and a second terminal, the first terminal normally connected to the second terminal when the external device is connected to the DC output member and disconnected from the second terminal when the external device is not connected to the DC output member; and a switch arranged within an inner space of the DC output member, the switch comprising a first magnet, a second magnet, and a movable conductive member arranged on the second magnet, the first magnet and the second magnet arranged to repel each other; wherein an end of the first terminal and an end of the second terminal extend into the inner space of the DC output member; wherein the external device is inserted into the inner space through the open end, the second magnet is pushed by the external device and moved away from the protrusion until the movable conductive member is electrically connected between the end of first terminal and the end of the second terminal, and power from the external power source is transmitted to the AC to DC converter through the first electrical wire.
