Nyko Game Boost for 3DS
Quickly and conveniently add up to two more hours of play time to your Game Boost
♦ Easily clip it to your 3DS
Charging: You can charge the Game Boost with the standard 3DS power adaptor. The Game Boost does not come with a power adapter to charge it.
Is your 3DS cable port broken? It is very common for the 3DS A/C adapter cable port to become broken or stop working. If so, the Game Boost has its own charging port that works with your 3DS A/C adapter. This way, you can charge both the 3DS battery, and the Game Boost.
NOTE: Only works with original Nintendo 3DS. Not compatible with the 3DS XL or "new" 3DS models.
Whether it's the final minutes of your game, or the championship game, the Game Boost will give you that extra power when you most need it.
