  • Power adapter
    Patent number: 10409348
    Abstract: A power adapter includes an universal serial bus (USB) interface, a control unit and a charging circuit. The universal serial bus (USB) interface connected to the electronic device, to receive level signals from the electronic device. The control unit electronically connected to the USB interface, to output a control signal according to the level signals received by the USB interface. The charging circuit electronically connected to the control unit and receiving the external power signal, to determine whether or not to output the external power signal to the electronic device according to the control signal outputted by the control unit.

  • Electronic device
    Patent number: 10254810
    Abstract: An electronic device includes a battery, a detecting unit, a comparing unit, a control unit and a charging circuit. The detecting unit is electronically connected to a universal serial bus (USB) interface to detect and determine whether or not the connecting device is a power adapter. The comparing unit outputs a level signal depending upon the comparing unit comparing a input signal received by the USB interface with a voltage threshold. The control unit controls the battery either to be charged by the connecting device through the charging circuit or the battery to supply power to the connecting device through the USB interface according to the level signal.
