Upgrade your Game Boy DMG from its low powered AA battery compartment to a drop-in USB C rechargeable battery pack. The RetroSix/Hand Held Legend CleanJuice Original for Game Boy adds 9.25 watts of power (compared to 2 watt for the largest AA batteries available) giving you almost 5 times the game time!

*This version is smaller in thickness compared to the DMG XL Cleanjuice. Current version of boards are black.


  • Charge at any time using a regular USB C cable, and even reverse charge the console from your phone if it supports power share. That means you can charge your GB while you are out, using your phone battery.
  • Connect battery to CleanJuice board (only fits in one way so don't worry).
  • Remove top shell battery spring. Leave the bottom two.
  • Place battery into shell with the wire coming out at the bottom left corner, and the battery pushing the top left spring in.
  • Push the battery down at the bottom end.
  • Place CleanJuice board on top of battery and push the springs down to make contact with top battery springs. 
  • Use a RetroSix USB C battery cover (sold separately, in various colors), or cut a hole for the USB C port using a 4mm drill bit and drill 3 holes in the center of the battery cover as shown in the image.
  • Put the back cover on the console, and you are ready to go.
  • Give the CleanJuice a full charge and enjoy hours of gaming! Check out this article to see how long it could last.
  • If the module is loose in the battery housing, you may use foam padding to hold it in place.


  • 1x Lithium ion rechargeable battery (9.25 watts)
  • 1x Cleanjuice PCB



  • Port on CleanJuice modules will rest at opening of battery cover. This means you do not insert the port into the opening but it sits flush with the cover.
  • Created by RetroSix.

Light Indicator Key:

  • If the PG labeled light on the board is on, this means the USB cable is providing power to the system. This also means you can power your console from the USB without draining the battery - plug and play option.
  • If the CHRG labeled light on the board is on, this means the USB is charging the battery. When it goes off, the battery is fully charged.
  • Both indicator lights will be on when module is charging. When module is fully charged, only the PG light will remain.
  • If you connect a USB cable and the PG light does not turn on, your cable or power supply are faulty.

Installation was ridiculously simple. Unit fit perfectly in OG Gameboy. Highly recommend getting the available battery door with the USB-C port pre-cut.

Awesome upgrade

This upgrade only took a few minutes to do. Now I can use USB C to charge and it lasts a while instead of going through all the AA batteries. The only thing is that if you shake the gameboy a little too hard while moving with it, the position of the pcb moves and you might not be able to power it on until you take the cover off and put it back to its proper position. Maybe I didn't put it in properly the first time but since I put it back the second time it hasn't happened again. Well worth the upgrade.

Icing on the cake

Perfect addition to my original DMG rebuild. I've been really happy with the functioning of the battery, and the ease of charging. Haven't run out of juice yet, top it up once a week and it's always ready when the urge to play strikes.


Battery barely fit and charging board didn’t want to stay in place without custom bracket.

Original (not xl) akku pack

Its so nice to have this mod, it give me more room to mod my old but beloved gameboy classic. :) i dont have any draining issues with this one (not xl version), and a can play hours with it. In this case, i dont do any case modification (cuting battery bay lines) , just the battery cover need some hole on it for usb c port. The board moved a little bit, when you plug an usb c cabel in it, but i solved this with a lego pieces. :)
