A power supply device using electric power network connects to an external power source and an electronic device, and supplies an alternating current power from the external power source to the electronic device to be a direct current power for the electronic device. In this case, the power supply device using electric power network comprises an electric power connection unit connected with the external power source, a conversion unit connected with the electric power connection unit, and an output unit connected with the conversion unit and the electronic device. The electric power connection unit is used for acquiring the alternating current power from the external power source, and the alternating current power is converted into a direct current power by the conversion unit. Thereby, the direct current power required for the electronic device during the process of charging and supplying power is supplied. |
