A game accessory power supply connector for compact computer devices such as, for example, hand held video games, utilizes the link port of the compact computer device to provide power to an accessory item connected thereto. The game accessory power supply connector includes an internally positioned power supply plug adapted to engage the link port of the game device when disposed in its operable position, and an externally positioned fully functional link port for use by the user while the connector utilizes the link port of the game device. By utilizing the link port of the game device, the accessory power supply connector can draw power for the connected accessory item from the power (batteries or AC connection) of the game device, and thereby does not require additional power supply for the accessory item.
