1. A wall socket, comprising:
a socket housing;
an input terminal, wherein the input terminal of the wall socket is configured to receive an input voltage from a power grid;
an output terminal arranged at a side of the socket housing and configured to output a dc output voltage;
a power converting circuit arranged in the socket housing and configured to convert the input voltage to the dc output voltage according to a control signal; and
a load detecting circuit configured to receive an identification signal outputted by an electronic device when the electronic device is connected to the output terminal, and output the control signal according to the identification signal to adjust a voltage level of the dc output voltage of the output terminal, in order to configure the dc output voltage of the output terminal to be the voltage level corresponding to the identification signal selected from a plurality of different voltage levels;
wherein the voltage level of the dc output voltage outputted by the same output pin of the ouput terminal of the wall socket varies according to the identification signal.
