Keychron Expands Its 8K Keyboard Lineup With Full-Size and Compact Models

Keychron is giving mechanical keyboard enthusiasts a reason to look at the numpad again. The company announced two new additions to its K Ultra 8K series — the K4 (96% layout) and the K10 (full 100% layout) — both designed for people who actually use that number cluster on the right.

Priced at $114.99 each, both keyboards support tri-mode connectivity — wired, Bluetooth, and 2.4 GHz wireless — with a polling rate that hits 8 kHz. That’s the kind of speed that matters less for everyday typing and more for competitive gaming, where every millisecond between a keystroke and on-screen action gets measured.

Inside, Keychron packed a 4000 mAh battery. Running at 8 kHz over ZMK firmware, the company claims up to 600 hours of battery life. The shell uses ABS plastic, but the internals are where the engineering shows: six layers of dampening fill, a steel positioning plate, and a PCB that supports hot-swappable switches with integrated RGB backlighting.

The keyboards ship with Keychron’s own Apex series switches. Buyers can pick between linear reds, tactile browns, or the early-tactile banana variant — the banana switches sit between reds and browns in feel, offering a bump that hits earlier in the keystroke for faster feedback. The keycaps are OSA-profile PBT double-shot, which means the legends won’t fade and the texture stays matte over time.

The K4 keeps a compact footprint by squeezing a numpad into a 96% layout — popular among desk-space-conscious users who still crunch numbers. The K10 goes full-size with every key in its traditional place. Both are available now at Keychron’s website.
