Charging equipment of cell phone for cutting off standby power

PURPOSE: A mobile phone charging device is provided to reduce power consumption by completely disconnecting an AC power source when a mobile phone is separated. CONSTITUTION: A mobile phone charging device comprises a stroke(219), a spring(217), a jack printed circuit board(201), and a charge part printed circuit board(203). The stroke is arranged in a jack. The stroke separates a first contact point from a second contact point in order to disconnect an AC power source which is applied to the mobile phone charging device. The spring returns the stroke to original location. The first contact point and the second contact point are located on the jack printed circuit board. The charge part printed circuit board changes an AC voltage which is inputted from the mobile phone charging device into a DC voltage.
