1. A non-contact charger capable of wireless data communication and power transmission, comprising:

  • a USB connector provided in one side of an enclosed device body to attachably and detachably couple with a USB port of a computer or a notebook computer using a jack;

    a USB driver block coupled to the USB connector and emulated with a USB protocol to receive and transmit data from and to the computer or the notebook computer;

    an MPU block coupled to the USB connector to control a serial resonator converter, a current sensing block and a power supply member, each for receiving a power source from the computer or the notebook computer and supplying the received power source to a mobile device, or receiving and transmitting data from and to the computer or the notebook computer; and

    a primary coil formed on the device body to generate an induced electromotive force so as to wirelessly transmit a data signal and a power signal from the serial resonator converter to the mobile device,wherein the serial resonator converter converts the data signal received and transmitted between the USB driver block and the mobile device and the power signal supplied from the USB connector 10 to the mobile device, and sums up the converted data and power signals, andwherein the current sensing block analyzes a signal of the secondary coil to recognize the mobile device, monitors the primary coil and the secondary coil to control a charge voltage to a stable voltage, and transmits a signal of the MPU block, the signal of the secondary coil being transmitted from the primary coil that senses a load regulation signal by means of the secondary coil corresponding to the primary coil and arranged in the mobile device.
