6. A charging device, comprising:
-
an alternating current (AC) to direct current (DC) converter, wherein the AC to DC converter includes a primary side that receives power from an AC power source and a secondary side that provides power to an external device; a switch connected between the AC power source and the AC to DC converter; and switching logic configured to; determine at least on of whether an external device is presently connected to the charging device or an external device connected to the charging device is fully charged; and send a control signal to the switch to set the primary switch to an off state when the switching logic determines that no external device is presently connected to the charging device or the external device is fully charged. - View Dependent Claims (7, 8, 9, 10)

11. A charging device, comprising:
-
a connector to receive at least one of a cord or an external device; an AC to DC converter, wherein the AC to DC converter includes a primary side that receives power from an AC power source and a secondary side that delivers power to the external device via the connector; a switch connected between the AC power source and the AC to DC converter; and an actuator extending from the connector to the switch, wherein the actuator mechanically sets the switch to an on state when at least one of a cord or an external device is plugged into or received into the connector. - View Dependent Claims (12, 13, 14)
