Abstract
The present invention discloses a power adapter device and a main computer system thereof. The power adapter device is provided for receiving a power signal from a power supply device and providing the power signal to an electric apparatus and an additional apparatus. The power adapter device comprises a power connection port, a first connection port, a second connection port, a current detecting module and a switch module. The power connection port is provided for receiving the power signal. When the electric apparatus receives the power signal via the first connection port, the current detecting module detects a current signal and generates a control signal according to the current signal. When the current detecting module generates the control signal, the switch module is turned on so as to transmit the power signal to the additional apparatus through the second connection port.
