Mobile Power GameCube is a rechargeable power supply that hooks up under the Nintendo GameCube (in a way similar to the Game Boy Player), making the Nintendo GameCube portable. It was obviously made with the GameCube LCD Screen in mind, as shown in the image. Unfortunately, this product did not get good ratings, recieving only two stars on Amazon.com.
Provides up to 1.5 hours of power to the Gamecube and an LCD screen (for example: the Gamecube Mobile Monitor)
Rechargeable battery fits under the GameCube, thus no extra bulk to carry around
