Abstract
A power saving device includes a first switch coupled between an input node and an output node, wherein the input node is coupled to a power source and the output node is coupled to an electronic device, a detection unit detecting the magnitude of a current, a charge unit coupled to the output node, wherein the charge unit correspondingly generates a detection signal in response to magnitude of the current, a battery pack coupled to the charge unit, a second switch disposed between the output node and the battery pack and a controller. When magnitude of the current in response to the detection signal is lower than a threshold current and battery capacity of the battery back is higher than a predetermined capacity, the controller outputs a set of control signals to turn off the first switch and turn on the second switch.
