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.

Multiport connector and power control method

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.

Charging system and charging method thereof

A power adaptor is provided. The power adaptor includes a voltage converter, a connecting port, a first transformer and a controller. The voltage converter receives an input voltage and determines whether to convert the input voltage to an output voltage according to an indicating signal. The first transformer includes a primary side and a secondary side. The primary side and the secondary side are coupled to each other, and a first end and a second end of the secondary side are coupled to the connecting port, respectively. The controller generates the indicating signal according to a voltage at the primary side of the first transformer. The connecting port is used to connect to an electrical device, and when the connecting port is electrically connected to the electrical device, a first end and a second end of the secondary side are short to a reference ground end of the secondary side.
