Keychron K8 Pro vs K9 Pro: your questions
The Keychron K8 Pro is an 80% (Tenkeyless) keyboard, which includes arrow keys and a navigation cluster. The Keychron K9 Pro is a 60% keyboard, which omits the function row, arrow keys, and navigation cluster for a much more compact footprint.
No. According to the manufacturer, the K9 Pro's hot-swap sockets are currently compatible with Gateron low-profile mechanical switches only. It does not support standard profile MX switches or low-profile optical switches.
The Keychron K8 Pro has a larger 4000mAh battery, while the K9 Pro has a 1550mAh battery. While actual runtime depends on usage, the K8 Pro's larger capacity suggests it will require less frequent charging.
Yes. Both the Keychron K8 Pro and K9 Pro feature open-source QMK firmware and are compatible with the VIA/Keychron Launcher web app for remapping keys and creating macros without installing software.
This depends on preference. The K8 Pro offers three adjustable typing angles and a standard OSA keycap profile. The K9 Pro has a fixed 3° angle and a low-profile keycap design, which some users find more comfortable for their wrists due to the lower height.
Yes. The K8 Pro comes with OSA profile double-shot PBT keycaps. The K9 Pro comes with low-profile double-shot PBT keycaps. PBT material is more resistant to oil and shine than ABS.
The K8 Pro has south-facing RGB LEDs, meaning the LED is on the bottom of the switch, shining away from the user. The K9 Pro has north-facing LEDs. South-facing placement prevents interference with Cherry-profile keycaps, a detail highlighted in the K8 Pro's description.
The K9 Pro has a 1000 Hz polling rate in wired mode for low latency, which is suitable for gaming. However, its 60% layout requires using function layer combinations for arrow keys, which may not be ideal for all games compared to the K8 Pro's dedicated keys.
Yes. The vendor listing shows a 'Barebone' version is available for the K8 Pro, which does not include switches or keycaps, allowing for full customization.
The K8 Pro is generally more beginner-friendly for modding. Its hot-swap version supports a vast array of common MX switches, and it includes pre-installed sound-dampening foam. The K9 Pro's modding ecosystem is currently limited to specific low-profile switches.
Yes. Both keyboards are fully compatible with macOS and Windows. They include keycaps for both operating systems and allow you to configure different keymaps for each within the QMK/VIA software.
Both keyboards feature a combination of aluminum and plastic/ABS in their construction. The K8 Pro listing specifies an 'Aluminum Frame' option, while the K9 Pro is described as having an 'ABS+Aluminum frame'.
