Keychron expanded its K Ultra lineup with the K1 Ultra 8K, a tenkeyless mechanical keyboard designed for users who prioritize response time and battery longevity. The 8kHz polling rate reduces input latency significantly, which matters to competitive gamers and typists who notice every millisecond of delay. This model joins the K5 Ultra and K8 Ultra variants, offering a compact form factor without sacrificing the low-profile mechanical switch experience.

TKL layout with 8kHz polling and 490-hour battery life
The K1 Ultra 8K features a TKL layout that removes the number pad to save desk space while maintaining full access to function and navigation keys. It runs on ZMK firmware, an open-source platform that allows for advanced customization and macro programming. The keyboard supports both Bluetooth and 2.4GHz wireless connectivity, giving users the flexibility to switch between devices seamlessly.
Specifications
- Layout: TKL (Tenkeyless)
- Polling Rate: 8kHz
- Battery Capacity: 2,600mAh
- Battery Life: Up to 490 hours (2.4GHz, backlight off)
- Firmware: ZMK
Under the hood, the keyboard houses a 2,600mAh battery that Keychron claims lasts up to 490 hours on 2.4GHz with the backlight turned off. The internal structure uses a four-layer noise-dampening material to reduce typing sound, creating a quieter typing experience. The case combines an aluminum frame for rigidity with rosewood accent side panels for aesthetic contrast.
Buyers can choose from three Keychron Milk POM switch options: the linear Red, the tactile Brown, and the soft tactile Banana. Each switch type comes paired with double-shot PBT keycaps for durability and resistance to shine. The keyboard is currently available on the Keychron online store for $109.99, positioning it as a mid-range option in the low-profile market.
We've been tracking K1 Ultra 8K closely — see our earlier coverage on Keychron K5 Ultra 8K Low-Profile Keyboard. The K1 Ultra 8K completes the initial wave of K Ultra models by offering a TKL variant alongside the full-size and compact options. The combination of high polling rates, long battery life, and customizable switches makes it a viable choice for dedicated keyboard enthusiasts.
