Ajazz AK820 Pro vs Keychron C3 Pro: your questions
The Keychron C3 Pro is better suited for competitive gaming. Its specified 8000 Hz polling rate minimizes input lag, a critical factor in fast-paced titles. The Ajazz AK820 Pro's maximum polling rate is 1000 Hz in its wired and 2.4GHz modes, and drops to 125 Hz in Bluetooth mode.
Yes. The Ajazz AK820 Pro vendor description states it is fully compatible with both Mac and Windows operating systems. It includes a function to switch between OS modes, which can be managed through its TFT screen interface.
Yes, the Keychron C3 Pro should work with Linux. The manufacturer states its Keychron Launcher web app, used for programming the QMK firmware, supports all operating systems and is accessible through Chrome, Edge, and Opera browsers.
Both are hot-swappable, making switch changes easy. However, the Keychron C3 Pro's listing provides more detail for modders, specifically naming its internal 3.5mm EVA acoustic foam, IXPE film, and silicone pad. Its open-source QMK firmware also offers a deeper entry point for software customization.
The Ajazz AK820 Pro has a 4000mAh battery. The vendor description states this ensures 'long and steady use', but does not provide an estimated battery life in hours. Actual runtime will depend on usage patterns, backlight brightness, and connectivity mode.
The Ajazz AK820 Pro uses OEM profile keycaps according to its technical specifications. The Keychron C3 Pro uses Cherry profile double-shot PBT keycaps, as stated by the manufacturer, which are typically lower in height.
Yes, both keyboards are hot-swappable. The Ajazz AK820 Pro supports 3-pin and 5-pin mechanical switches. The Keychron C3 Pro also supports hot-swapping with almost all 3-pin and 5-pin MX-style switches, including brands like Cherry and Gateron.
Both have sound-dampening features. The Keychron C3 Pro's description explicitly lists multiple foam layers (EVA, IXPE, silicone) and pre-lubed switches for a quieter sound. The Ajazz uses a gasket mount and flex-cut design to reduce vibration and noise, but does not detail specific foam types.
The Ajazz AK820 Pro's 0.85-inch TFT screen acts as an interactive interface. According to the vendor, it can display customizable visuals, battery status, date and time, connectivity mode, operating system, and backlight effects, providing at-a-glance information.
Yes. The Keychron C3 Pro offers three levels of adjustable typing angle: 4°, 6°, and 8.7°, as listed in its specifications. This provides ergonomic support to suit different user preferences.
The Keychron C3 Pro specifically uses 'shine-through' Cherry profile PBT keycaps to allow the north-facing RGB backlight to illuminate the legends. The Ajazz AK820 Pro uses south-facing RGB LEDs with double-shot PBT keycaps, which should also allow for shine-through effects.
Based on the listings, the Ajazz AK820 Pro includes the keyboard, three extra keycaps, a 2-in-1 switch/keycap puller, a USB cable, a 2.4GHz receiver, and a manual. The Keychron C3 Pro listing does not detail its included accessories, so a direct comparison cannot be made.
