This product is a handheld power drill that uses a 555 motor and a Type-C 20V 3.25A power supply. However, your fast charger must support Type-C 20V 3.25A output, otherwise it will only provide 5V 2A power. The Type-C 20V 3.25A power supply module is a circuit board I designed myself. If needed, I can provide the design file for reference.
