Keychron C3 Pro vs Lemokey P3 HEWired 8K vs Wireless Hall Effect

No, the C3 Pro is wired-only, connecting over USB-C. It has no Bluetooth or 2.4 GHz mode, so you will need a cable at all times. The Lemokey P3 HE is the wireless option in this pair, with 2.4 GHz and Bluetooth 5.2.

No, the P3 HE is built for magnetic Hall Effect switches and is compatible only with Gateron double-rail magnetic switches according to Keychron. It does not support other magnetic switches such as Gateron Magnetic Jade or Gateron KS-20. The C3 Pro is the opposite: its hot-swap sockets take almost any 3-pin or 5-pin MX-style mechanical switch.

The C3 Pro reaches 8000 Hz in wired mode and can be switched among 1000 Hz, 4000 Hz, and 8000 Hz in the Keychron Launcher web app. The P3 HE runs at 1000 Hz in both wired and 2.4 GHz wireless modes, and at 125 Hz over Bluetooth. For raw polling numbers, the C3 Pro is higher.

Rapid Trigger activates and deactivates keys based on travel distance rather than a fixed actuation point, so a press registers and resets immediately. Keychron pairs it with adjustable actuation from 0.2 to 3.8 mm, Dynamic Keystrokes for up to 4 actions per key, and an Analog Mode for variable input. The C3 Pro does not list Rapid Trigger or magnetic switch features.

Yes, both list QMK firmware support plus a web-based configurator, Keychron Launcher for the C3 Pro and Lemokey Launcher for the P3 HE. Both support key remapping, macros, and backlight customization through the browser, with Chrome, Opera, or Edge recommended. The P3 HE adds HE-specific settings like actuation and Rapid Trigger in its launcher.

Keychron rates the 4000 mAh battery at up to 120 hours, with the caveat that lab results vary with actual use. Real-world runtime will depend on backlight brightness and connection mode. The C3 Pro has no battery because it is wired-only.

The P3 HE weighs 1910 g plus or minus 50 g, roughly double the C3 Pro's listed 912 g. Much of that comes from the 6063 aluminum case and aluminum plate, which Keychron says reduces vibration for a quieter typing feel. The C3 Pro's ABS plastic case keeps it lighter but less dense.

Yes, both ship with Cherry profile double-shot PBT keycaps designed for oil resistance and legends that resist fading. The C3 Pro's keycaps are shine-through to pair with its north-facing RGB. The P3 HE is offered in shine-through and non-shine-through versions, both double-shot PBT per Keychron.

It has useful office features, including Bluetooth 5.2 for three devices, a knob, and a gasket mount with silicone beans for a cushioned feel. The 4000 mAh battery rated up to 120 hours helps keep cables off the desk. The aluminum case is designed to reduce resonance, which suits shared spaces.

Yes, Keychron describes a screwless structure with magnetic latches that lets you lift the top case off without tools and snap it back in seconds. That design is aimed at cleaning and modification. The C3 Pro does not list a tool-free disassembly feature, so check the user guide before opening it.

Yes, the C3 Pro lists Mac and Windows support with an FN plus Caps Lock shortcut for switching between the two systems. Keycaps for the layout are part of the package. The P3 HE likewise supports macOS, Windows, and Linux, and Keychron says it ships with an extra set of keycaps for Windows and macOS and can save a layout for each.

It depends on what you value. The C3 Pro offers an 8000 Hz wired polling rate for fast signal transmission, while the P3 HE offers Rapid Trigger, adjustable actuation, Dynamic Keystrokes, and Analog Mode on magnetic switches. The P3 HE also gives you 1000 Hz over 2.4 GHz wireless, which the C3 Pro cannot match because it is wired-only.
