AULA EA75 Max vs Royal Kludge RK89Screen vs Numpad Choice

The Epomaker EA75 Max has a significantly larger 5000mAh battery, while the Royal Kludge RK89 has a 1850mAh battery. Based on the listed capacities, the EA75 Max should last much longer between charges during wireless use.

Yes. The RK89 uses an 89-key layout, which Royal Kludge describes as an 85% layout that brings the number pad back into a compact form factor. It saves space compared to a full-size keyboard but retains the numpad.

The EA75 Max uses a gasket-mount structure where the plate is suspended on soft gaskets. This is combined with five layers of dampening materials, including a Sandwich Pad, IXPE Switch Pad, PET Sound-Enhancement pad, Bottom Foam, and Bottom Silicone, to create a softer, more cushioned typing sound and feel.

Yes, both the Epomaker EA75 Max and the Royal Kludge RK89 are hot-swappable. This means you can replace the mechanical switches without soldering. The EA75 Max supports both 3-pin and 5-pin switches.

The Epomaker EA75 Max offers a silent linear switch option called Cotton Candy switches. The RK89's vendor description lists clicky, tactile, and linear switches, but does not specify a silent variant. Therefore, the EA75 Max is the clearer choice for a quiet environment.

The RK89's vendor specifications list 'Blue backlighting' and '20 onboard Blue backlit modes'. This indicates it has single-color blue backlighting, not full per-key RGB lighting with multiple colors like the EA75 Max offers.

According to Epomaker, the TFT screen on the EA75 Max can display the time, date, keyboard battery life, connectivity status, and operating mode. It can also show custom GIFs and provide real-time feedback when adjusting settings with the knob.

Yes. The EA75 Max uses double-shot PBT keycaps in a Cherry profile, which are generally more durable and resistant to shine. The RK89 uses double-shot ABS keycaps, which may develop a shiny appearance with prolonged use but often have brighter backlighting.

Only the Royal Kludge RK89 includes built-in USB connectivity. It has two USB 2.0 passthrough ports and one Type-C port, allowing you to connect other devices directly to the keyboard.

Both keyboards offer software for customization, but with caveats. The EA75 Max has a driver for key remapping and macros, though a user review noted it can be hard to find. The RK89 has DIY software support, but its vendor page notes the programmer is only for Windows and must be run in wired mode.

The Epomaker EA75 Max has a 75% layout, which is generally more compact as it omits the numpad and function cluster. The RK89, while an 80% size, incorporates a numpad, making it wider. For pure space savings, the 75% EA75 Max is the more compact option.
