“Feels very solid, and doesnt slide around on my desk pad. Keys are very satisfying.”
Keychron Q3 Ultra
5 owner reviews
“USB is working for me, but I have it plugged in to a USB switcher. I haven't configured the keyboard, beyond the switches in the back. I'm liking the keyboard so far.”
“USB on keeps dropping out, even after firmware update (1.0.2) and reset. Tried multiple computers, windows and Mac. Half the time it doesn’t work at all.”

Keychron Q0 Max vs Q3 Ultra: your questions
No, the Q0 Max is specifically a numeric keypad. It lacks letter keys, a spacebar, and other essential keyboard functions. It is designed to be used alongside a separate primary keyboard.
An 8000 Hz polling rate can reduce input latency compared to a standard 1000 Hz keyboard, which may be perceptible in fast-paced competitive gaming. The manufacturer states it makes latency hardly noticeable in competitive games.
The Q3 Ultra has a significantly larger 4000mAh battery, with the manufacturer claiming up to 660 hours with backlighting off. The Q0 Max has an 1800mAh battery with up to 50 hours at the lowest RGB brightness.
Both keyboards come with KSA profile double-shot PBT keycaps, which are oil-resistant and durable. The Q0 Max listing specifies non-shine-through keycaps, while the Q3 Ultra listing does not specify shine-through status.
Yes, both the Keychron Q0 Max and Q3 Ultra feature hot-swappable PCBs. This allows you to install most 3-pin and 5-pin MX-style switches without soldering.
QMK and ZMK are both open-source firmware for customization. QMK is traditionally associated with wired and 2.4GHz boards, while ZMK is designed with a focus on robust Bluetooth connectivity. Both can be configured via the Keychron Launcher web app.
Yes, the Q3 Ultra weighs 1787 grams, which is over 2.5 times the weight of the 684-gram Q0 Max. This is due to its larger aluminum case and bigger internal battery.
The Q0 Max is highlighted by customer reviews for content creation, as its rotary knob can be programmed for timeline scrubbing or brush adjustments. Its separate form factor also allows placement next to a graphics tablet.
Yes, both the Keychron Q0 Max and Q3 Ultra are listed as compatible with macOS, Windows, and Linux. They include keycap sets for both Mac and Windows layouts.
Yes, according to the vendor description, the Keychron Q0 Max is available in a Barebone Knob version, which does not include keycaps and switches. The Q3 Ultra is listed only as a Fully Assembled unit.
Both keyboards use screw-in PCB stabilizers. The manufacturer states this design increases stability and makes for a smoother typing experience on larger keys, and they are easier to change or upgrade.
