    Exclusive Keychron Super Switch

    Exclusive to Keychron, the Super switch is molded with unparalleled precision. A mini hole in the socket dome of the bottom housing reduces air resistance for a smoother keystroke, while the arched transparent top housing maximizes light transmittance for more consistent, brighter backlighting. Rated for 50 million clicks, it delivers reliable, high-performance typing for fast and competitive use.

    Largest Battery

    The K2 is built to keep up with your busiest weeks. Powered by a 4000 mAh big battery, it delivers up to 240 hours of typing on a single charge with the backlight off — that's months of daily use between charges. Fewer interruptions, fewer cables, more focus on what you're typing.

    Compact Yet Powerful

    Description:The K2's 84-key design keeps all the essential function keys — Page Up/Down, Home, End, and Screen capture (Cmd+Shift+4) — for maximum productivity. With N-key rollover (NKRO on wired mode), you can press as many keys as you want at once without missing a single character.
