Abstract
An input system includes a first input device and a second input device. Each of the first input device and the second input device includes a main body, a first connecting port, at least two second connecting ports, a power switching circuit and a control unit. When the first connecting port of the first input device is connected with an external power source, the power switching circuit of the first input device receives a first voltage from the external power source. When one of the second connecting ports of the first input device is connected with one of the second connecting ports of the second input device, the first voltage is converted into a second voltage by the power switching circuit of the first input device and the second voltage is transmitted to the second input device.
