The utility model relates to a depolarizing quick charger of a mobile phone battery, which adopts an ultra high-frequency switching power supply. A pulse charging and discharging type circuit is adopted by a charging mode, and the charging, the discharging and the detection of a pulse period are controlled by a pulse counting circuit. A bulky power transformer is omitted by the utility model, and the weight of the utility model is lightened. The charging and the discharging are alternately processed by an added charging and discharging control circuit, and a polarization phenomenon of a battery can be effectively overcome. An added precise comparison and detection circuit processes detection in each charging and discharging interval period, detection is accurate and reliable, and overcharging can be effectively avoided. A moving pin is suitable for various sockets, the utility model is designed by adopting an injection molding and simulating knap surface, and thus appearance is beautiful.
