<![CDATA[The earth's energy reserves will be depleted due to the growing demand for energy, necessitating the adoption of renewable energy sources. The best way to replace it is to use the energy that flows through water to create electricity. Batteries can also be utilized to store electrical energy for later use. In this study, the batteries used to turn the water's energy into electricity are portable generators that can be carried anywhere. By needing a portable unit that is made from a turbine, generator, charger controller, auto buck bost converter, battery, and other supporting parts. It functions as a charger for computers, cellphones, and other electronic devices without a 12V battery that may change the voltage. Compare the variance in the water flow discharge and the power charger's charging time using the results that were obtained. River discharge 73.621 l/s charging time 42 hours, river discharge 73.621 l/s charging time 42 hours, pipe discharge 6.41 l/s charging time 84 hours, pipe discharge 8.064 l/s pipe charging time 38 hours, pipe discharge 9.868 l/s charging time 32 hours, and pipe discharge 14.42 l/s pipe 27 hours were the results. The battery charges more quickly the higher the discharge.]]>
