Keychron K3 Max
Standard Layout

- Features screw-in stabilizers and multiple plate material options (Aluminum, Plastic, Polycarbonate) for advanced modding.
- Smaller 1550mAh battery may require more frequent charging than the K15 Max.
- Standard 75% layout does not offer the same ergonomic typing angle as the K15 Max's Alice layout.

“This keyboard is perfect for me. Combined with the side-scrolling mouse I purchased, it does everything I need it to do, and is extremely comfortable to use all day.”
“My biggest issue is easily that they advertise these products as being Linux compatible, but as a recent convert, I wasn't aware how often companies will claim that, but then offer little or no support for actual functionality. When trying to flash updated…”

“Noce keyboard, i appreciate the level of customization QMK provides. One thing was little disappointing - the tactile feeling comparing to K3. Other than that its very good kb!”
“I sold my k3 pro and got this. The one I got drops connection intermittently or doesn't type or respond right away. It sounds nice, but stiff reds are not as pleasant to type on as previous keyboards reds. I really thought I ordered hotswap RGB max but seems…”

Keychron K15 Max vs K3 Max: your questions
The Keychron K15 Max has a larger 2000mAh battery, while the Keychron K3 Max has a 1550mAh battery. Based on battery capacity alone, the K15 Max may offer longer periods between charges for wireless use.
The K15 Max uses an Alice layout with a non-standard bottom row, which makes it harder to fit standard keycap sets. It comes with low-profile double-shot PBT keycaps from the manufacturer. Users should look for keycap sets specifically designed for Alice or low-profile layouts.
Yes, the K3 Max is available in multiple layout standards including ISO-UK, ISO-DE, ISO-Nordic, and ISO-SW, in addition to ANSI. This makes it a better choice for users who prefer ISO key arrangements.
Both keyboards offer similar gaming performance with a 1000 Hz polling rate on wired and 2.4 GHz modes, N-key rollover, and QMK support for remapping. The choice depends on whether you prefer the ergonomic Alice layout of the K15 Max or the more traditional layout of the K3 Max.
Yes, the K15 Max supports QMK firmware and can be programmed using the Keychron Launcher web app. This allows for full key remapping, macros, and custom shortcuts. The keyboard also includes extra macro keys for easy access.
Yes, the manufacturer lists screw-in stabilizers as a feature of the K3 Max. This is an upgrade for modding, as screw-in stabilizers are generally more secure and produce less rattle than cheaper clip-in stabilizers.
The Keychron K3 Max is lighter at 580 grams compared to the K15 Max at 700 grams. The K3 Max also has smaller dimensions (306x116 mm) versus the K15 Max (370x143 mm), making it the more portable option for travel.
Yes, both the K15 Max and K3 Max support the Keychron Launcher web app for customizing keymaps, macros, and RGB lighting. The manufacturer states the Launcher is compatible with Chrome, Edge, and Opera browsers on Windows, macOS, and Linux.
According to the manufacturer, both keyboards feature advanced IXPE acoustic foam and resilient latex foam inside the case to reduce keystroke noise and improve acoustics.
The hot-swappable version of the K15 Max is available as an option. It is compatible with Gateron and Keychron low-profile mechanical switches only, as the manufacturer notes QMK does not support low-profile optical switches.
Based on customer reviews, the K3 Max does not include onboard storage for the 2.4 GHz dongle. Users may need to keep the dongle separate or use a carrying case for storage.
