Many outdoor activities are often carried out by the community. An emergency power is required to recharge the batteries of lighting equipment, communication equipment and other electronic equipment. Power bank as emergency power has a limited capacity so that it is not enough to meet the needs of power for several days. A portable power generation is needed to generate electricity using available natural resources such as running water or wind. The objective of this research is to develop a portable power generation system to meet the needs of electrical energy during outdoor activities. The portable power generation system consists of a small turbine, a small generator, and a battery charger. The prototype was tested in the laboratory and in the field. Tests showed the DC generator generated a voltage of 0.7 - 11.1 V when rotated at a speed of 117 - 1434 rpm. The step up converter produces a voltage of 2.2 - 15.74 V when the input voltage is 1.5 - 12 V. The boost module produces a voltage of 3.19 - 4.38 V when the input voltage is 3 - 12 V. The portable power generation system will generate electricity if the minimum speed of the running water is 4.8 m/s. When tested using wind power with speeds between 4.0 - 10.3 m/s, the portable power generation system produces a voltage of 1.4 - 9.3 V.
