Game Boy Color: USB-C Charging Kit


In stock

SKU: GBC-1 Category:


The Game Boy Color USB-C Charging Kit is a circuit that allows to charge a Nintendo Game Boy Color by USB-C and use a Li-ion battery instead of AA batteries.

This kit includes two boards. If you want to install it easy, it’s enough with the main board which doesn’t need any cable for working. However, if you want to have the status LEDs in the same place as the original status LED, then you will need to solder the second board and joint both with 3 cables. You can choose the best option for you.


  • Exact shape for Game Boy Color.
  • Li-Ion battery charger by USB-C with overvoltage and undervoltage protection.
  • Integrated LED indicators on the main board, next to the USB for charging battery (red) and full battery (green). It can be disabled by the jumper SJ1.
  • External LED indicators board for playing (white), charging battery (red) and full battery (green). Optional installation.


  • 1 frame board which includes the two boards: charging and light.
  • 1 Battery cable (with connector JST SH1.0)
  • 1 Cable of 2 wires for connecting the light board.
  • 1 Light diffuser pipe.



This module has been designed to be used with the console’s original voltage regulator because it supports an input voltage range between 2 a 4.6V and the battery kit provide a voltage between 2.75 a 4.2V. If you also want to change the original power supply, it’s important it is compatible with the voltage provided for the battery kit, otherwise you may damage something.

Since the version 1.7 has changed its shape, the features are the same but the battery connector has been moved to a place where it’s not necessary to cut the plastic shell.

Frequently Asked Questions

Can I play and charge the battery at the same time?

The electronic board doesn’t have support for it. You shouldn’t play and charge at the same time.

Can I use this board with others boards?

You can do it as long as the board you want to install is compatible with the voltage supplied by this board. Remember it can be between 2.75 to 4.2V, for example, this modules work great:

    • CleanPower Regulator (photo)
    • CleanAmp v1.1 Audio Amplifier (photo)
    • Pololu 5V Step-Up Voltage Regulator U1V10F5 (link)

The speaker or/and headphones make noise with the USB-C charging kit.

There are some conditions that can do the GB makes noise. For example, if your GB power regulator is too used/old, or you have installed an IPS screen that drains too much energy, etc. you can have this problem.
You can solve this in most of the cases replacing the original power supply for other compatible (the input voltage must support between 2.75 to 4.2V)

The GBC doesn’t turn on.

If you have replaced the capacitors in your GBC, make sure that the capacity is the same as the original capacitors. Otherwise, this may cause the console not to turn on, or only turn on when connected via USB-C.
