The Game Boy Pocket USB-C Charging Kit is a circuit that allows you to charge a Nintendo Game Boy Pocket via USB-C and use a Li-ion battery instead of AAA batteries.

This module has been designed to be used with the console's original voltage regulator, as it supports an input voltage range between 2 and 4.6V, while the battery kit provides a voltage between 2.75 and 4.2V. If you also want to change the original power supply, it’s important to ensure it is compatible with the voltage provided by the battery kit; otherwise, you may damage the components.
