Abstract: A charging device with anti-theft function includes a power-supplying unit, a load-connecting unit and an anti-theft unit. The anti-theft unit includes a detector component connected electrically to the load-connecting unit, a control module connected electrically to the detector component, and an alarm module connected electrically to the control module. The detector component is configured to generate a charge detect signal when electricity from the power-supplying unit is transferred to a load through the load-connecting unit. The control module is configured to deactivate the alarm module in response to receipt of the charge detect signal from the detector component.
