GoKawiilThe 660 hours of battery life is impressive, but is perhaps not all that necessary on such a large board. And typists may want to swap out the switches and keycaps.

Keychron first announced its new Q6 Ultra 8K at CES 2026 — a full-size, wireless mechanical keyboard with a hot-swappable PCB and up to an 8,000 Hz polling rate. Which isn't too unique, until you take a look at the rated battery life: up to 660 hours, over a 2.4GHz wireless connection with an 8,000 Hz polling rate (and the lighting turned off). That's significantly longer than any other 8 KHz polling rate keyboard (or peripheral), and it's because the Q6 Ultra 8K is one of the new Keychron keyboards that utilizes ZMK firmware instead of QMK firmware — ZMK is optimized for wireless efficiency, and, well, it clearly makes a difference.
The Q6 Ultra 8K is a large, sturdily-built keyboard with a full aluminum body and double-shot PBT keycaps, which makes it a good option for gamers who want a full-size board (there aren't that many out there). But it's going to need more than a very impressive battery life to land a spot on our list of best wireless keyboards . The Q6 Ultra 8K is available now for $239.99, in both black and white colorways.
Design and Construction of the Q6 Ultra 8K
The Q6 Ultra 8K is a wireless mechanical keyboard with a roomy, full-size layout, an all-metal build, and a double-gasket design. It comes fully assembled, with a programmable rotary knob, in black (black case and black and dark gray keycaps with teal accent keys) or white (white case and white and gray keycaps with red accent keys). Our review unit came in black.

The Q6 Ultra 8K is a sturdy, well-built keyboard housed in an all-metal chassis. Unsurprisingly, it's pretty hefty, weighing in at just under five pounds (4.93lbs / 2,238g). Its black aluminum top case features sharply angled corners and a moderately-sized bezel; it's not particularly unique, but it does look very clean. The bottom case is slightly smaller — also black aluminum, with a standard 5.3-degree typing angle. The back features a decorative gold-colored back plate with a futuristic celestial pattern printed on it.

This is a large, full-size keyboard, with alphanumeric keys, a full navigation cluster, a 10-key numberpad, and a set of four extra macro keys above the numberpad. It measures approximately 17.56 inches (446mm) wide by 5.39 inches (137mm) deep, and is 1.22 inches (31.09mm) high at the back, not including the keycaps. With the keycaps, it's just under 2 inches (50mm) high at the back, and is approximately 1.37 inches (34.8mm) at the front. It's a relatively high keyboard, and I expect most people will feel more comfortable with a wrist rest.
