PROBLEM TO BE SOLVED: To obtain a power device which enables stable start of an electronic apparatus which can be operated by a plurality of kinds of power sources, regardless of the kinds of power device used. SOLUTION: The power device has a power storage element 7 which is connected to a load 4, a power supply means (11) which is arranged between power sources 1a, 1b, 1c and the storage element 7 and charges the storage element 7, kind-distinguishing means (9a, 9b, 9c) for distinguishing the kinds of power sources for supplying power to the supply means (11), and a control means for controlling the supply means (11), on the basis of detection signals form the kind-distinguishing means. The control means adjusts the charged quantity of the storage element 7 charged by the power supply means, according to the discharging abilities of the power sources, whose kinds are distinguished by the kind-decision means, on the basis of the detection signals of the kind- decision means. |
