Triboelectric nanogenerator (TENGs) is one of the promising energy harvesting methods, and is expected to serve as primary power source. Nevertheless, previous TENGs were only able to generate low-current outputs. Even when energy management systems (EMSs) are used for TENGs, electrical losses occurred owing to complicated EMS circuits. Accordingly, high-mechanical inputs were still necessary to match power levels for existing electronics. Therefore, film capacitor-based charge-carrier TENGs (FCC-TENGs) are fabricated herein. These can be easily utilized for various circuits owing to their ultrahigh output with low input. As film capacitor-covered charge-carrier cylinders are rolling, FCC-TENGs can produce high voltage and current outputs of about 5000 V and 10 A, respectively, and can effectively reduce friction and wear. By loading external load, the root mean square power of FCC-TENG is measured up to 720 mW. Given the generated outputs, FCC-TENG can be used as primary power source for several power supply circuits that can turn on 12 commercial 5 W light-emitting diodes, power electric device, and charge lithium-ion battery.
