The steel plate provides responsive feedback and a peaceful typing sound, while added weight will enhance the stability.

Suitable For All Devices
Built with the Mac users’ experience in mind while still retaining compatibility with Windows devices, the K2 Max comes with a system toggle and an additional set of customized keycaps for both Windows and macOS systems. You can now save two different layouts on the keyboard, one for each system.

An Epic Core Inside
A powerful ARM architecture MCU equipped with 256KB Flash will provide more flexibility for developers. The polling rate is 1000 Hz on 2.4GHz and wired modes right out of the box, which makes the latency hardly noticeable even in competitive games.

Hot-Swappable (Optional)
Every detail matters for a personalized typing experience, that’s why we give you the power. You can hot-swap every switch on the K2 Max with almost all of the 3pin and 5pin MX style mechanical switches on the market (including Cherry, Gateron, Kailh, Panda, etc.) without soldering. You can customize your own typing experience in seconds.

Keychron Super Switch
Our exclusive Keychron Super switch adopts a new mold with unparalleled precision. Every switch is tested for pro-grade quality and has a lifespan of up to 50 million clicks, providing great reliability and high performance for long typing sessions. Its new light affection structure on its transparent top housing also ensures high light transmittance and a more consistent, brighter backlight effect.

OSA Profile Double-shot PBT Keycaps
To further fine-tune your typing experience, the K2 Max comes with our unique OSA profile (OEM profile with spherical-angle) and double-shot PBT keycaps that aim to provide a more comfortable fingertip feel with excellent oil resistance for long-term use on the 75% layout.

Screw-In PCB Stabilizers
Even a small part matters for your fingertip feel. We’ve integrated the PCB-mounted screw-in stabilizers for a smoother typing experience with less wobbliness on the big keys such as space bar, shift, enter, and delete. The Keychron K2 Max also supports third-party screw-in PCB stabilizers.

South-facing RGB Backlights
The south-facing RGB is designed to better illuminate the keyboard backlight from the typist’s angle. The south-facing RGB is also free from interference when the user installs Cherry-profile alternative keycaps on their keyboard.

Comes with more than 22 types of RGB backlight settings. You can further fine-tune the RGB hue, saturation, brightness, effect speed with ease.

Ergonomic Support
Three levels of adjustable typing angle (5º, 9º & 12º) and curved OSA-profile keycaps are all working together to provide long-lasting ergonomic support for your wrist.
