Ajazz AK820 Pro vs AULA M75: your questions
The AULA M75 has a significantly larger 8000mAh battery, which should provide a much longer lifespan between charges compared to the Ajazz AK820 Pro's 4000mAh battery. The vendor for the AULA M75 states it lasts for days on a full charge.
Yes, the Ajazz AK820 Pro vendor page lists a downloadable driver for the ANSI version. This software is implied to allow for customization of the RGB lighting, TFT screen display, and potentially key remapping.
Yes, the AULA M75 is more than twice as heavy. It weighs 1735g (approximately 1.74 kg), while the Ajazz AK820 Pro weighs 810g (0.8 kg). This substantial difference is due to the AULA's full aluminum chassis.
Yes, both keyboards are hot-swappable. The Ajazz AK820 Pro specifically supports 3-pin and 5-pin mechanical switches. The AULA M75 listing also confirms hot-swap capability, allowing for easy switch replacement without soldering.
Both use a gasket mount design for a softer typing feel. The Ajazz AK820 Pro has a detailed construction with a flex-cut polycarbonate plate and PCB, plus sound dampening. The AULA M75 vendor describes a five-layered internal padded structure including sandwich and silicone padding. The specific sound and feel will depend on the installed switches.
Yes, the Ajazz AK820 Pro vendor description explicitly states it has Mac and Windows compatibility. It also mentions that the TFT screen can be used to switch between operating system modes.
According to its technical specifications, the Ajazz AK820 Pro has a 1000Hz (1kHz) polling rate when used in wired or 2.4GHz wireless mode. In Bluetooth mode, the polling rate is 125Hz.
The Ajazz AK820 Pro comes with several accessories in the box. These include a USB A-to-C cable, a wireless 2.4GHz receiver, a 2-in-1 switch and keycap puller, three extra keycaps, and a user manual.
Both keyboards use PBT plastic keycaps, which are more resistant to shine and wear than ABS. The Ajazz AK820 Pro uses double-shot OEM profile keycaps, while the AULA M75 uses dual-tone OEM profile keycaps.
The Ajazz AK820 Pro features south-facing RGB LEDs. This is an advantage for using Cherry-profile or other low-profile keycaps, as it prevents interference and allows for better backlight shine-through. The AULA M75's LED orientation is not specified.
The AULA M75 vendor claims an ultra-low latency of 3ms for its wireless connectivity. This is a marketed specification for responsive performance, but the type of wireless mode this applies to (2.4GHz or Bluetooth) is not detailed in the provided information.
