Charging device

A charging device is proposed. The charging device is configured to charge to at least one electronic equipment. The charging device includes at least one charging socket. The at least one charging socket includes at least one expanding structure, an accommodating slot and a charging terminal. The at least one expanding structure is disposed on at least one side of the at least one charging socket, and includes two conductive terminals and at least one positioning portion. The at least one positioning portion and the two conductive terminals are toward to a same direction. The accommodating slot is configured to accommodate the at least one electronic equipment. The charging terminal is disposed in the accommodating slot, and electrically connected to the at least one electronic equipment and the two conductive terminals. Thus, the charging device of the present disclosure can be expanded via the expanding structure, and the charging device can charge to a plurality of electronic equipment without a limitatio
