PURPOSE: A device for supplying power of a portable terminal is provided to mount the second battery on the first battery by being electrically connected to the first battery, in order to use a large-capacity battery, thereby increasing power capacities with simple portability. CONSTITUTION: A hooking groove(102) and a fixing button(103) are formed on one side of a body(101). The first battery(110) is removable by being coupled with the hooking groove(102) and the fixing button(103). The second battery(120) is electrically mounted on a back side of a front side of the first battery(110) contacted with the body(101). The first battery(110) comprises as follows. The first front ground terminal(111) is projected in a lower side of a front part(110a) to supply power to a terminal. The first hooker(113) is formed in the lower side of the front part(110a) to be coupled with the hooking groove(102). The first back ground terminal(112) is formed in a lower side of a rear part(110b). The first hooking groove(114) is formed in the same method as the hooking groove(102). A fixing groove(115) is formed to insert the first hooking projector into an upper surface of the battery(110).
