Full 96% Layout

- Massive 8000mAh battery promises exceptionally long wireless use.
- Features a detailed five-layer sound dampening package for acoustics.

Your primary need dictates the winner. If you work with numbers, value maximum battery life, and have a permanent desk setup, the AULA F99 is the more practical productivity tool. If you want a sleek, portable keyboard with a unique screen for customization and are willing to use layers for the numpad, the Ajazz AK820 Pro offers more modern flair in a smaller package. Consider how often you truly use a numpad versus how much you value desk real estate.

What will you mostly use it for?
The AULA F99 is the clear choice for office work and content creation where a numpad and extended battery life are critical. For travel and highly space-constrained desks, the Ajazz AK820 Pro's compact form is superior. Gaming and programming are a toss-up, depending on whether you prefer the Ajazz's screen and smaller footprint or the AULA's rapid trigger and full navigation keys. Modders may lean towards the AULA for its explicitly layered sound-dampening construction.
It's a tie
- Both offer tri-mode connectivity with 2.4GHz wireless for low latency.
- Both feature gasket-mounted designs for a cushioned typing feel.
- The AULA F99 lists a rapid trigger feature, while the Ajazz AK820 Pro has a 1k polling rate in wired/2.4G mode.

“I am really enjoying using AULA f99! UX is 10/10 The only negative thing is the battery indicator, I find it quite confusing therefore I turned it off alltogether.”
“Good product - poor service. The order wasnt filed and the stock ran out. Then for the replacement item to be filled it took way too long for the order to arrive and complete a customer build.”

Ajazz AK820 Pro vs AULA F99: your questions
The AULA F99 has a significantly larger 8000mAh battery compared to the Ajazz AK820 Pro's 4000mAh battery. According to the manufacturer's specifications, this should translate to much longer usage time between charges for the AULA F99, making it better for extended wireless sessions.
No, the Ajazz AK820 Pro uses a 75% layout. This layout removes the numpad and the function key row to achieve a more compact size. You would need to use a function layer combination to access number pad functions.
The Ajazz AK820 Pro features a 0.85-inch TFT screen. The vendor description states it can display customizable visuals, battery status, date and time, connectivity mode, operating system, and backlight effects, serving as an interactive interface for settings and information.
Yes, both keyboards are hot-swappable. This means you can pull out the installed mechanical switches and replace them with other compatible 3-pin or 5-pin switches without any soldering required, allowing for easy customization of the typing feel.
Both use a gasket mount design for a softer, more cushioned typing feel. The AULA F99 specifically lists a five-layer sound package including foam and film, which is designed to improve acoustics. The Ajazz AK820 Pro uses a flex-cut PC plate and PCB. The final sound will also depend on the installed switches and keycaps.
The Ajazz AK820 Pro's keycaps are listed as doubleshot PBT. The AULA F99 uses PBT keycaps with a Cherry profile, but the specific manufacturing technique (doubleshot or dye-sublimated) is not detailed in the provided vendor description for the AULA model.
Yes, both the Ajazz AK820 Pro and AULA F99 list Mac compatibility in their extra features. The Ajazz vendor page also mentions you can switch between Win and Mac modes using its TFT screen.
Rapid trigger is listed as an extra feature for the AULA F99. This is a gaming-oriented feature that allows for faster keystroke repetition by resetting the actuation point immediately after a key is partially released, rather than waiting for it to return fully to the top.
The Ajazz AK820 Pro is more portable. It is lighter at 810g versus 1023g, and its 75% layout has dimensions of 327mm x 136mm, which is significantly more compact than the AULA F99's 391mm x 147mm 96% layout, making it easier to pack.
The Ajazz AK820 Pro includes three extra keycaps, a 2-in-1 switch and keycap puller, a USB cable, a 2.4GHz receiver, and a manual. The AULA F99 includes a 2.4GHz receiver, a switch puller, two spare switches, and a USB Type-C cable.
The Ajazz AK820 Pro uses south-facing LEDs, which shine from the south side of the switch. The AULA F99 uses north-facing LEDs. South-facing LEDs prevent the LED housing from interfering with the legends on Cherry-profile keycaps, while north-facing LEDs can sometimes cause this interference.
