Keychron V3 Max vs Lemokey P3 HE

The Lemokey P3 HE has a full 6063 aluminum body and aluminum plate, resulting in a heavier, more rigid feel than the V3 Max's ABS plastic housing and PC plate. The P3 HE also features a screwless magnetic latch design and mirror-polished back strip, while the V3 Max uses a traditional gasket mount with sound-absorbing foam.

No, the P3 HE is only compatible with Gateron double-rail magnetic switches sold on Keychron and Lemokey websites. It does not support standard 3-pin or 5-pin MX mechanical switches found on the V3 Max.

The Keychron V3 Max is better suited for programming due to its availability in ISO layouts like German and Nordic, plus its OSA profile PBT keycaps and softer PC plate. It also supports full QMK and VIA remapping, allowing customized layers for coding shortcuts.

Both keyboards support 2.4 GHz, Bluetooth, and wired USB-C connections with a 1000 Hz polling rate in 2.4 GHz and wired modes. The V3 Max uses Bluetooth 5.1 while the P3 HE uses Bluetooth 5.2, and the V3 Max includes dual Type-C and Type-A receivers that store in a magnetic slot.

The Keychron V3 Max is significantly more portable at 895 g compared to the P3 HE's 1910 g. Its ABS plastic case is also less susceptible to scuffs, and the V3 Max's included dual receivers add convenience for on-the-go use.

The P3 HE features Gateron double-rail magnetic switches with adjustable actuation from 0.2 to 3.8 mm, Rapid Trigger for instant key resets, Last Key Priority for smoother directional changes, Snap Click, Dynamic Keystrokes for multiple actions per key, and analog mode for variable input.

Yes, both the V3 Max and P3 HE come with a system toggle switch and additional keycaps for both macOS and Windows. The V3 Max vendor description specifically mentions saving two different layouts for each system, while the P3 HE includes an extra set of customized keycaps.

The V3 Max has south-facing RGB LEDs that avoid interference with OEM or Cherry profile keycaps, while the P3 HE has north-facing RGB LEDs. The P3 HE offers per-key RGB and Mix RGB (splitting the keyboard into two zones) with 22+ backlight settings including static white.

Both keyboards use screw-in PCB stabilizers for reduced wobbliness on large keys like space bar and shift. The V3 Max supports third-party screw-in PCB stabilizers, while the P3 HE relies on its specific screw-in design for stability.

The Keychron V3 Max is easier to mod due to its hot-swap support for any 3-pin and 5-pin MX switches, PC plate, and compatibility with third-party stabilizers. The P3 HE's screwless magnetic latch allows tool-free disassembly but is limited to proprietary Gateron double-rail magnetic switches.

Both keyboards have a 4000 mAh rechargeable li-polymer battery. The V3 Max offers up to 190 hours wireless working time with backlit off and up to 100 hours with RGB at lowest brightness. The P3 HE provides up to 120 hours wireless working time based on lab tests.
