Abstract: A charger circuit and an intelligent charging control method thereof are disclosed. The charger circuit comprises a power circuit used to generate a charging voltage, a charging output switch, an MCU and an electrical appliance plug-in detection circuit, wherein the MCU is connected to a positive output terminal or a negative output terminal of the power circuit through a current sampling element to detect a charging current in a charging loop and is connected to a positive connecting terminal of a charging interface to detect a charging voltage in the charging loop. In this way, a charger is able to intelligently judge whether or not a to-be-charged electrical appliance is plugged into the charging interface, automatically charges the electrical appliance in a corresponding charging mode and effectively prevents overcharging of batteries of consumer electrical appliances, thus, prolonging the battery life and avoiding disasters caused by overcharging of the batteries.

Abstract: A socket with a power display function comprises a socket input terminal, a power measurement chip, a single-chip microcomputer and a display module. The power measurement chip is connected to the socket input terminal through a voltage sampling module and a current sampling module and is used to measure and figure out the voltage, current and power consumption of the socket. The single-chip microcomputer is connected to an output terminal of the power measurement chip, has an output terminal connected to the display module and is used to receive output information of the single-chip microcomputer and to display corresponding information contents according to the received information. The socket can effectively remind users of to save electricity and to use electricity safely.
