Mini‐generators based on locomotion of small objects have aroused widespread attention because of their potential application in powering small‐scale electronic devices. Although improvements have been made in the development of mini‐generators, there are still some key challenges such as low power output and energy conversion efficiency, which limit the potential application of mini‐generators. Herein, through integrating a superhydrophobic surface, chemical reaction and solenoid coil/magnet into a system, an innovative mini‐generator is designed, which can convert chemical energy into electrical energy through mechanical form. As a result, the energy conversion efficiency and output power are both three hundred times higher than previously reported results and can be applied to power light‐emitting diodes without amplification. We believe that the proposed mini‐generator provides more chance for the application of self‐supplying power sources for electronic devices.
