Portable charger

摘要

Provided is a portable charger connected to a wall electric power source and configured to supply an electric power from the wall electric power source to a load. The portable charger includes a plug, an electric wire, a switch, a first detection unit, a second detection unit, and a control unit. The control unit is configured to supply an electric power through the electric wire to the load when the plug is plugged in the socket and to cut off the supply of the electric power flowing through the electric wire by controlling the switch on the basis of the user's approach that is detected by the first detection unit, and the tensile force that is detected by the second detection unit while the electric power is being supplied.

1. A portable charger connected to a wall electric power source and configured to supply an electric power from the wall electric power source to a load, the portable charger comprising:
a plug inserted in a socket that is installed in the wall electric power source; an electric wire connecting the plug and the load to supply an electric power from the wall electric power source to the load; a switch disposed between the plug and the electric wire; a first detection unit configured to detect a stress applied to the plug or a touch on the plug; a second detection unit disposed in the electric wire and configured to detect a variation of a tensile force applied to the electric wire; and a control unit configured to supply an electric power through the electric wire to the load when the plug is plugged in the socket and to allow the electric power supplied to the load to be cut off by controlling the switch based on the detected stress, the detected touch and the detected variation of the tensile force while the electric power is being supplied to the load.
