PURPOSE: A portable power generator is provided to control the efficiency of generating power as energy density is controlled on the basis of the charging pressure of compressed air. CONSTITUTION: A portable power generator comprises a hydraulic pressure generating unit, a hydraulic cylinder, a gas power generating unit, a gas generator(400), and a charging unit. The air bag(110) of the hydraulic pressure generating unit compensates flow volume changes generated by pumping incompressible fluid The hydraulic cylinder is forcibly moved forward by compressing the fluid in a cylinder tube(210). The gas power generating unit forms a high pressure gas chamber, and high pressure gas is additionally compressed as much as the volume of a piston rod inserted by the initial charging pressure. The gas generator generates electricity using the flow of high pressure gas from the high pressure gas chamber. An indicator(620) of the charging unit is electrically connected to a printed circuit board, and controls the charging pressure. |
