Accessories

• The Game Boy Battery Pack (or AC Adapter), sold for about US$30, was roughly 3 in. long, 2 in. wide, and 0.5 in. thick. One end of it had a 2 inch-long cord, ending in a 3.5 mm phone plug, while the other end had a standard mains plug. The first version of it was gray with purple lettering, to match the colors used on the Game Boy. It also featured a belt clip. The battery pack was good for several hours of gameplay per charge, providing an alternative to purchasing more AA batteries once their power was exhausted. The product used nickel-cadmium batteries, lasted about 4-5 hours per charge, and could be charged roughly 1000 times before a significant loss in effectiveness. A major drawback of the battery pack was its weight, as well as the way the phone plug stuck out prominently.[34]

• Released at the same time as the Game Boy Camera, the Game Boy Printer was a thermal printer. It ran on six AA batteries. In addition to printing out Game Boy Camera photos, it also ran in conjunction with several Game Boy games, such as The Legend of Zelda: Link's Awakening DX, Pokémon Yellow: Special Pikachu Edition, and "Super Mario Bros. DX".
