A charging cabinet and a control method thereof are disclosed. The charging cabinet includes a controller, a power supply, switches, a charging detector, a status detector, and sockets electrically connected to devices. The switches are selectively tuned on to connect a current path between one of the sockets and the power supply. When a current value of the current path is smaller than a preset current value, the charging detector products a first detection signal. The status detector produces a second detection signal after counting up to more than a preset time period, during which the charging cabinet stays at a suspension status. The controller turns on at least part of the switches after counting up to more than an idle time period, during which the switches in the charging cabinet at the suspension status are tuned off according to the first and second detection signals.
