Micro-hydroelectric power generation is a term used to describe hydroelectric power generation systems with a
generating capacity of 100 kW or less, and is a method of generating electricity using a small flow of water. Compared to conventional hydroelectric power generation, which requires large dams, micro-hydroelectric power generation is attracting attention as a renewable energy source because it has less impact on the environment. Furthermore, if the components can be made labor-saving, maintenance and operating costs can be kept relatively low. The objective of this study was to recharge mobile batteries with a small amount of water. Experimental results showed that if the flow velocity could always be maintained at 3.8 L・min－1 or higher, power generation of 5V or higher would be possible. Next, the charging performance was verified. It was found that a mobile battery with only an input port and a power requirement of 12 W could generate more than 12 W because it was capable of charging. However, mobile batteries that support input and output could not be charged. These results suggest that the generation capacity of this study is femto-generation.
