Abstract: A power adapter includes a power converting circuit, a connecting terminal and a controller. The power converting circuit is used to convert an input voltage to an output voltage according to a control signal. The connecting terminal is connected to an electronic device to allow the output voltage outputted by the power converting circuit to charge the electronic device. The controller receives an identifying command from the electronic device when the electronic device is connected to the connecting terminal, and outputs the control signal according to the identifying command.

Abstract: A multiport connector and a power control method are provided. The multiport connector comprises a power output port and multiple power input ports. The power output port is connected to an electronic device. The power input ports are connected to multiple power adapters to form multiple power transmission paths. Each power transmission path comprises a power line, a detecting circuit and an impedance component connected to the detecting circuit in series. Therefore, when the electronic device is connected to the multiport connector, the electronic device detects the equivalent impedance formed by the impedance components on the detecting circuits to adjust an upper limit of load power.

Abstract: A charging system includes a transmission line, a power adaptor, and an electronic device. The transmission line includes a first terminal and a second terminal. The power adaptor is coupled to the first terminal and generates a charging voltage and a first voltage signal. The charging voltage is at a first voltage level. The electronic device is coupled to the second terminal and receives the first voltage signal. When the first voltage signal is larger than a first preset voltage signal, the electronic device outputs a second voltage signal to the power adaptor. When the second voltage signal is larger than a second preset voltage signal, the power adaptor adjusts the charging voltage into a second voltage level.
