Ajazz AK820 Pro vs Keychron V5 MaxCompact Screen vs Full Layout

The Ajazz AK820 Pro is better for small desks. Its 75% layout measures 327mm in length, which is significantly shorter than the 392mm length of the Keychron V5 Max. This compact design removes the number pad but retains arrow and function keys to save space.

The Keychron V5 Max supports full key remapping through its native QMK and VIA firmware, which is open-source and highly customizable. The Ajazz AK820 Pro relies on its proprietary driver software for customization, and its level of remapping is not detailed to the same extent as QMK/VIA.

Yes, both keyboards list Mac and Windows compatibility. The Keychron V5 Max includes an additional set of keycaps for Mac modifiers and has a system toggle switch. The Ajazz AK820 Pro vendor states you can switch between Win and Mac modes via its TFT screen.

The Keychron V5 Max lists a 1000 Hz polling rate specifically for its 2.4 GHz and wired modes, which is a common spec for gaming. The Ajazz AK820 Pro also states a 1000 Hz polling rate in its 2.4 GHz and wired modes, but the Keychron emphasizes a powerful ARM MCU for low latency in its marketing.

Both keyboards have a 4000mAh battery. The Keychron V5 Max manufacturer provides estimated working times of up to 190 hours with backlighting off. The Ajazz AK820 Pro vendor does not provide specific runtime estimates, only stating the battery ensures long use.

Yes, both keyboards are hot-swappable, supporting both 3-pin and 5-pin mechanical switches. This allows you to change switches without soldering. The Keychron V5 Max is also available as a barebones kit without switches or keycaps pre-installed.

According to the vendor, the 0.85-inch TFT screen on the Ajazz AK820 Pro acts as an interactive interface. It can display customizable visuals, battery status, date and time, connectivity mode, operating system, and backlight effects without needing dedicated software running.

The Keychron V5 Max does not include a palm rest in the box. However, Keychron sells separate silicone and resin palm rests that are compatible with 96% layout keyboards, which are frequently suggested as add-ons in their store.

Both keyboards feature sound-dampening foam and a gasket mount design to reduce noise. The Keychron V5 Max uses a PC plate and screw-in stabilizers, which can contribute to a consistent sound signature. The Ajazz AK820 Pro uses a flex-cut PC plate and PCB for a softer feel. The final sound depends heavily on the switches installed.

The Keychron V5 Max uses double-shot PBT OSA profile keycaps that are listed as 'not shine-through.' Its south-facing LEDs are designed to illuminate the board from the typist's angle. The Ajazz AK820 Pro uses double-shot PBT OEM keycaps, but it is not explicitly stated if they are shine-through.

The Keychron V5 Max offers extensive ISO layout support, including ISO-DE, ISO-ES, ISO-FR, ISO-Nordic, ISO-UK, and others. The Ajazz AK820 Pro, based on the provided information, is only listed with an ANSI US layout, making the Keychron the clear choice for European users needing specific key legends.

The Ajazz AK820 Pro includes the keyboard, three extra keycaps, a 2-in-1 switch and keycap puller, a USB A-to-C cable, a 2.4GHz receiver, and a manual. The Keychron V5 Max (fully assembled) includes the keyboard, a Type-C cable, a Type-A to Type-C adapter, and both Type-C and Type-A 2.4GHz receivers.
