The DMG-01 takes four AA (LR6) batteries and there was an official Rechargeable Battery Pack, DMG-03, available at launch, that could provide portable or AC power. In this post, I will discuss battery life among the four members of the 8-bit Game Boy line, the original DMG Game Boy, the Game Boy Pocket, the Game Boy Light and the Game Boy Color. Second, it had far superior battery life to any of its rivals. First, it came with the killer-app pack-in, Tetris. The Game Boy had two huge advantages over its rivals. However, its rivals the Atari Lynx, Sega Game Gear & Nomad and the NEC Turbo Express, could have easily eclipsed it with their color screens. In the palms of the player's hands they had much of the power of the NES.

(While the Microvision had been released in 1979, the games themselves attached to the base and provided controls and CPU as well as program code). When the Game Boy was released in 1989, it was the first portable video game system using interchangeable cartridges.
