Construction Details

Aesthetically, the keyboard boasts a minimalist and modern design, characterized by its ultra-thin profile—measuring just 5.2mm at its thinnest point—and a subtle tilt angle of 3.2 degrees for ergonomic support. The body and keycaps are crafted from durable ABS plastic, ensuring a lightweight yet sturdy build that withstands daily use. The ANSI layout provides familiarity for most users, while the concave keycaps are sculpted to fit the natural curvature of the fingertips, reducing typing fatigue and enhancing precision. The keyboard’s integrated frame offers stability, preventing wobbling during intense typing sessions. Its compact footprint (374.5 x 131.6 mm) and weight of just 585 grams make it easy to carry in a backpack or laptop bag. Despite its slimness, the construction does not compromise on durability, and the included silicone key skin adds an extra layer of protection against spills, dust, and wear, ensuring long-lasting performance.

Cross-Platform Compatibility

This keyboard excels in cross-platform versatility, supporting seamless operation across macOS, Windows, and Linux systems. Its triple-mode connectivity allows users to choose between Bluetooth 5.2 for wireless convenience, 2.4 GHz for ultra-low latency, and wired USB-C for uninterrupted performance. Switching between devices is effortless—simply toggle the connection mode to pair with up to three devices simultaneously, making it perfect for multitaskers who juggle between a laptop, tablet, and smartphone. The Bluetooth connection is stable and energy-efficient, while the 2.4 GHz wireless mode delivers a high polling rate of 1000 Hz, ensuring responsive input for demanding applications. The 300mAh battery provides up to 300 hours of use on a single charge, and the keyboard can be used while charging, eliminating downtime. The USB-C port ensures fast and reliable charging, with a full recharge taking approximately 2.5 hours. The keyboard’s compatibility extends to both Mac and Windows layouts, with dedicated multimedia and function keys that mirror Apple’s keyboard shortcuts, making it an excellent choice for users who operate in mixed-OS environments. The Keychron Launcher app further streamlines device switching and configuration, enhancing the overall user experience.

Tailoring Your Typing

Personalization is at the heart of this keyboard’s appeal. Through the Keychron Launcher web app, users can remap keys, create custom macros, and assign shortcuts tailored to their workflow. This level of customization empowers users to optimize their typing experience for productivity, gaming, or creative tasks.

Although the keyboard does not feature backlighting, its sculpted, concave keycaps provide tactile feedback and visual clarity, making typing comfortable and precise even in low-light environments. The included silicone key skin not only protects the keys but also offers a subtle, customizable touch for those who prefer a softer typing surface. Users can also personalize their setup with third-party keycap sets, thanks to the standard ANSI layout.
