Royal Kludge RK84 vs Yunzii YZ75 ProHub vs Battery & Keycaps

The Yunzii YZ75 Pro has a larger 5000mAh battery compared to the Royal Kludge RK84's 3750mAh battery. While actual runtime depends on usage and lighting, the YZ75 Pro has a higher capacity for potentially longer wireless operation.

Yes. According to the manufacturer's description, the RK84 is armed with two built-in USB 2.0 passthrough ports and one Type-C port. This allows you to connect other devices like a mouse or headset directly to the keyboard.

The YZ75 Pro comes with PBT keycaps, while the RK84 uses ABS keycaps. PBT plastic is generally more durable and resistant to the shiny wear that ABS keycaps develop over time. The YZ75 Pro's keycaps are also listed as using a 5-side dye-sub or double-shot process.

You can physically install them on both hot-swappable boards. However, the YZ75 Pro has a specific advantage as it uses south-facing RGB LEDs. North-facing LEDs, which the RK84 likely uses, can interfere with the sound and feel of Cherry-profile keycaps.

The Yunzii YZ75 Pro may have an edge for quietness. Its vendor description states it includes double layers of sound-absorbing foam and pre-lubed stabilizers, which are mods typically done to reduce keyboard noise. The RK84 offers a clicky switch option, which is notably louder.

Yes, both the Royal Kludge RK84 and Yunzii YZ75 Pro list Mac and Windows support in their specifications. The RK84 vendor page explicitly lists compatibility with Mac, iOS, and Android operating systems.

According to the Royal Kludge product description, the RK84 has a removable outer frame. This lets you customize the look and you can remove it to give the keys a floating appearance, which can also make cleaning easier.

The RK84 is listed as having screw-in stabilizers, which are generally more secure than clip-in types. The YZ75 Pro vendor claims its stabilizers are pre-lubed, which should reduce rattle and improve the typing feel out of the box.

The Royal Kludge RK84 includes a more comprehensive accessory pack. According to its listing, it comes with a keycap and switch puller, four replacement RK switches, magnetic pad feet, a USB-C cable, and a USB receiver. The YZ75 Pro's included accessories are not detailed beyond the cable and dongle.

The vendor description for the YZ75 Pro includes a note stating its programming software can only work on Windows systems. For Mac users, functionality would be limited to any onboard controls or shortcuts.

The RK84 is lighter, weighing 803.5g compared to the YZ75 Pro's 940g. Both have a 75% form factor, but the RK84's lower weight could make it slightly more convenient to carry in a bag. The YZ75 Pro's larger battery may mean less frequent charging while away.
