Keychron K4 Wireless Mechanical Keyboard (Version 2)

    A 96% Wireless Mechanical Keyboard

    The K4 Version 2 (ANSI) combines full-size functionality in a compact 96% design with 100 essential keys, including a number pad. Connect to up to 3 devices via Bluetooth 5.1 or use the USB Type-C wired mode, and enjoy hot-swappable Gateron G Pro switches, a 4000 mAh battery for up to 240 hours of typing (backlight off), and included keycaps for both macOS and Windows.

Core Highlights

    With Number Pad in a 96% Layout

    With 100 keys in a compact 96% layout, the K4 Version 2 (ANSI) keeps the full number pad and essential keys for macOS and Windows in a small footprint, with a relocated Del key for easier access. *Num Lock works with Windows OS only.

    Wireless & Wired Multi-Device Connectivity

    Connect the K4 to up to 3 devices via Bluetooth and switch among your smartphone, laptop, and iPad effortlessly, powered by a high-reliability Broadcom Bluetooth 5.1 chipset. A USB Type-C wired connection is also available for stable home, office, and light-gaming use.

    Long-Lasting 4000 mAh Battery

    Powered by a 4000 mAh battery, the K4 Version 2 delivers up to 240 hours of typing on a single charge with the backlight off (up to 72 hours with RGB on), so you can keep working for weeks without hunting for a cable.

    Comfortable, Ergonomic Typing Angle

    An inclined bottom frame and adjustable feet set a relaxed typing angle that keeps your wrists comfortable through long sessions, while the compact 96% footprint leaves plenty of room for your mouse.
