ニンテンドーゲームボイ用バッテリーパック

The rechargeable pack clicks onto the back of my old Game Boy and holds a charge for a solid afternoon of Tetris sessions. The fact that it's used but still works flawlessly is a nice bonus for the price I paid.

Snagged this used pack for my original Game Boy and it clicks onto the back just like it should, no wobble. Battery life gets me through a solid weekend of Tetris without hunting for AAs. Exactly what my dusty console needed.

The clip-on design is solid, so it doesn't wobble during long sessions on the original console. It's used, so the charge doesn't last forever, but it gets the job done for a few hours of Tetris.
