Keychron is shaking up its wireless lineup with the quiet launch of two new models the Q6 Ultra 8K and V1 Ultra 8K. These keyboards, currently exclusive to Best Buy, introduce more than just new switches and a subtle redesign. They also mark a significant firmware shift that could dramatically improve battery life.
ZMK firmware unlocks serious battery potential

The biggest change under the hood? Keychron has dropped QMK for ZMK, a firmware specifically designed for wireless keyboards. While average users may never notice this swap, it’s a big deal for performance and efficiency. ZMK uses far less power, which should translate into longer use between charges even with smaller batteries.
For context:
- ZMK-powered Keychron B2 Pro: ~300 hours from an 800 mAh battery
- QMK-powered Keychron Q1 Max: ~100 hours from a 4,000 mAh battery (backlight off)
That’s not a one-to-one comparison, but the difference is hard to ignore. If Keychron applies the same ZMK efficiency across its Ultra 8K lineup, users could see multi-fold battery improvements over older QMK models.
New switches and design tweaks roll out with the Ultra 8K series
The Q6 Ultra 8K is a full-size board, while the V1 Ultra 8K offers a more compact 75% layout. Both come with Keychron’s new Milk POM switches, aiming to blend smooth keystrokes with long-term durability. While detailed specs on actuation force and travel aren’t public yet, POM-based switches typically focus on slick, low-friction typing experiences.
Aside from the firmware and switch overhaul, Keychron confirmed a visual design refresh is coming for these models but didn’t reveal specifics yet.
A wider Ultra 8K rollout is coming in 2026
For now, these Ultra 8K keyboards are Best Buy exclusives. But Keychron plans a broader release through its own online store in early 2026, including additional Q and V Ultra models.
What makes the Ultra 8K series notable isn’t just the hardware it’s the platform shift. Moving to ZMK marks a long-term commitment to better wireless efficiency, a smarter firmware base, and potentially fewer compromises between lighting, layout, and battery life.
Why the firmware shift matters
ZMK is built from the ground up for wireless needs unlike QMK, which was originally made for wired keyboards. For enthusiasts and everyday users alike, that means:
- Lower idle power draw
- Smarter sleep modes
- More consistent wireless behavior
- Longer runtime without bigger batteries
For Keychron, it means unlocking better performance without reinventing its entire design language.
The move to ZMK firmware might fly under the radar, but for battery life, it’s the most meaningful update in years.
