Keychron Lemokey X0 vs Lemokey X4Gaming Keypad vs Full 75% Keyboard

No, the Keychron X0 is a 35-key keypad. It lacks a full alphanumeric section, so you would need a separate keyboard for typing tasks like documents or emails.

The X4 uses a gasket mount, where the plate is suspended by rubber gaskets for a potentially softer, more consistent typing feel. The X0 uses a tray mount, where the plate is screwed directly into the case bottom, which is a more traditional and rigid design.

No. The Keychron X4 uses a detachable USB Type-C to Type-A cable. The Keychron X0 has a non-detachable USB-A cable, though it offers three routing grooves on the bottom case.

The Keychron X0 is significantly smaller (149 x 245 mm) and is designed to free up desk space for your mouse. The X4, while compact for a 75% layout, is much larger (325 x 145 mm) and requires more space.

Yes. Both the Keychron X0 and X4 feature hot-swappable sockets, allowing you to change the mechanical switches without soldering.

The X0 comes with OEM profile ABS keycaps. The X4 offers a choice: one version with OEM profile ABS keycaps and another with Cherry profile PBT keycaps, as stated in its product listing.

Yes. Both the Keychron X0 and X4 list compatibility with Windows, Linux, and macOS systems.

Both keyboards have a 1000 Hz polling rate, which the manufacturer states makes latency hardly noticeable in competitive games.

The vendor description for the Keychron X4 mentions it includes an aluminum knob and has knob support, suggesting a rotary knob is part of the design.

They offer different ergonomic features. The X0 has an integrated silicone palm rest. The X4 has three levels of adjustable typing angle (4°, 8°, 10°) and curved keycaps but no built-in wrist rest.

Both keyboards run QMK firmware and are customized through the Lemokey Launcher web app. This allows for key remapping, macro creation, and control over the red backlight modes.

According to the vendor descriptions, both keyboards come with pre-lubed Keychron Mechanical switches (excluding clicky variants) for a smoother typing feel out of the box.
