Keychron K4 Bluetooth Mechanical Keyboard – RGB Backlit, Wireless & Wired, 100-Key Layout
The Keychron K4 Bluetooth Mechanical Keyboard combines a compact full-size layout with mechanical switches, RGB illumination, and versatile wired/wireless connectivity. Its 100-key design retains a dedicated numeric keypad while reducing the overall footprint, making it suitable for both productivity and gaming setups.
Connect wirelessly through Bluetooth or use the included USB Type-C cable for a stable wired connection. The K4 can pair with up to three Bluetooth devices, allowing you to switch between computers and other compatible devices. Dedicated Mac/Windows compatibility and included replacement keycaps make it easy to adapt the keyboard to either operating system.
The keyboard features RGB backlighting with 15+ lighting effects, mechanical switches, and ergonomic rubber feet for a comfortable typing angle. Its built-in 4000 mAh rechargeable battery provides approximately 3–5 weeks of typical use with the backlight disabled, or approximately 20–80 hours depending on RGB brightness and usage.
