PURPOSE: A dual mode power supply unit of a mobile terminal is provided to allow two mobile terminals to share a battery by being coupled to the dual mode battery of which electric charges make a rated voltage and current flow to the terminals. CONSTITUTION: A battery coupling surface(111) is provided at one rear side of a main body(110) so as to be coupled to one side of a dual mode battery(130) for supplying power to operate a mobile terminal. A support protrusion(113) having a plurality of fixing grooves(112) is formed at a lower end of the battery coupling surface(111). A power terminal coupling protrusion(114) is formed at both upper sides of the support protrusion(113). A coupling protrusion(115) lets the battery(130) to be caught as being fixed in the fixing groove(112) and supported by the support protrusion. A coupling release protrusion(116) is formed to release engagement by pushing the coupling protrusion(115). The battery(130) has front and back main body coupling surfaces(131) to which two mobile terminals are respectively coupled. Two coupling recesses(134) are formed at an upper portion thereof, into which a coupling protrusion(115) of the main body(110) is inserted and fixed. At a lower portion of the main body coupling surface(131), power terminals(133) are formed to supply power by being in contact with power terminal coupling protrusions(114) of the main body(110), and a plurality of fixed protrusions(132) are formed corresponding to the fixing groove(112).
