Patent ID: 8300442

Claim:
A power adaptation device, applicable to supplying power to an electronic device, comprising: a terminal seat; a mechanical probing terminal, wherein the probing terminal is movably disposed at the terminal seat, and is located between a power-on position and a power-off position; a detection unit, coupled to the probing terminal; an electric power modulation unit, wherein the electric power modulation unit is electrically connected to an external power; and a control unit, coupled to the electric power modulation unit and the detection unit; wherein the detection unit notifies the control unit whether the probing terminal is located at the power-on position or the power-off position, when the probing terminal is located at the power-on position, the control unit controls the electric power modulation unit to modulate the external power; and when the probing terminal is located at the power-off position, the control unit controls the electric power modulation unit to reduce a total power consumption.
