Abstract: A power supply system with identification code updating capability is used for providing an electric power to an electronic device having a first identification (ID) code. The power supply system includes a power supply device and an ID code updating module. The power supply device is configured to provide the electric power to the electronic device and includes a memory unit. The memory unit is configured to store a look-up table including at least one second ID code. The ID code updating module is electrically connected to the power supply device. When the second ID code listed in the look-up table does not match with the first ID code of the electronic device, the ID code updating module updates a second ID code matching with the first ID code in the look-up table. A charging method is further disclosed.

Abstract: A power supplying apparatus includes a voltage outputting module and a voltage selecting module. The voltage selecting module is electrically connected to the voltage outputting module. The voltage selecting module includes a returning unit. The voltage selecting module receives a voltage identification signal when the voltage outputting module is electrically connected to an electronic device. When the voltage identification signal is larger than a voltage level, the returning unit notifies the electronic device, such that the electronic device returns a voltage request signal. The power supplying apparatus selectively sends out one of a plurality of DC voltage signals to the electronic device according to the voltage request signal.

Abstract: A fast charging apparatus includes a power conversion unit, a feedback module, a feedback adjustment module and a voltage mode fast charging signal processing module. The power conversion unit includes a pulse width modulation controller. The pulse width modulation controller includes an electronic apparatus current fast charging signal detection unit. The feedback module informs the power conversion unit to increase a charging power for an electronic apparatus if the electronic apparatus sends a voltage mode fast charging signal to the voltage mode fast charging signal processing module. The electronic apparatus current fast charging signal detection unit informs the power conversion unit to increase the charging power for the electronic apparatus if the electronic apparatus current fast charging signal detection unit detects a current mode fast charging signal sent from the electronic apparatus.
Abstract translation: 快速充电装置包括功率转换单元，反馈模块，反馈调节模块和电压模式快速充电信号处理模块。 功率转换单元包括脉宽调制控制器。 脉宽调制控制器包括电子设备当前快速充电信号检测单元。 如果电子设备向电压模式快速充电信号处理模块发送电压模式快速充电信号，则反馈模块通知电力转换单元增加电子设备的充电电力。 如果电子设备当前快速充电信号检测单元检测到从电子设备发送的当前模式快速充电信号，电子设备当前快速充电信号检测单元通知电力转换单元增加电子设备的充电功率。

Abstract: A power adapter with a power saving mode includes a power adaptation unit. The power adaptation unit includes a pulse width modulation control unit and a power saving signal receiver. The power saving signal receiver is electrically connected to the pulse width modulation control unit. When the power adapter enters a working status, the power adapter charges a battery. After the power saving signal receiver receives a battery fully-charged signal, the power adapter enters a sleeping status.
