Is the Nintendo GameCube a Handheld?

No. The GameCube (2001) is a home console. It requires AC power, connects to a TV via AV/Component/HDMI (with adapter), and uses wired or WaveBird wireless controllers. It has no built-in screen or battery.

Portable Misconceptions

• Game Boy Player (accessory) lets GameCube play GBA games on TV—not portable.
• Panasonic Q (Japan-only) adds DVD playback—still a set-top box.
• Car adapter kits existed for road trips but needed external screen.

Nintendo's handhelds of that era: Game Boy Advance, Game Boy Advance SP, Nintendo DS.
