PROBLEM TO BE SOLVED: To provide a temporary power supply for a cellular phone capable of supplying two or more different voltage and that can be manufactured easily without generating heat, and to provide a temporary power supply for the cellular phone that can use dry cells used in many applications, capable of adjusting the number of the dry cells to be mounted inside a casing depending on a required voltage and the like, and that can use the dry cells efficiently. SOLUTION: This detachable temporary power supply for the cellular phone has a feeder circuit comprising power sources 1 utilizing at least four or more pieces of the dry cells. The feeder circuit consisting of the power sources 1 can feed power. At least one or more pieces of the dry cells of the power sources can be detached. The feeder circuit can be structured, too, with the power sources 1 using the remaining dry cells after the detachment of one or more pieces of the dry cells. Thus, power can be fed by the temporary power supply having the feeder circuit of this structure. COPYRIGHT: (C)2004,JPO&NCIPI
