FAQ

GravaStar Mercury K1 vs Keychron Lemokey P1: your questions

The GravaStar Mercury K1 has a larger 8000mAh battery compared to the Keychron P1's 4000mAh battery. Based on the specifications, the GravaStar should offer significantly longer usage time between charges, which is a major advantage for wireless use.

The vendor description for the GravaStar K1 mentions a downloadable driver but does not specify support for open-source firmware like QMK or VIA. The Keychron P1, however, explicitly supports both QMK and VIA, as well as a proprietary Lemokey web app, for extensive key remapping and macro creation.

The Keychron P1 comes with double-shot PBT keycaps that the manufacturer describes as 'non-shine through.' It features south-facing RGB LEDs, which are designed to better illuminate the keys from the typist's perspective, but the keycaps themselves are not translucent for shine-through legends.

The Keychron P1 is more customizable. It is available as a barebones kit, supports QMK/VIA firmware, includes screw-in stabilizers, and uses multiple layers of acoustic foam (IXPE, PET, absorbing foam). The GravaStar K1 is hot-swappable but lacks the same level of documented firmware and barebones options.

Yes, both the GravaStar Mercury K1 and the Keychron P1 list Mac and Windows support in their specifications. The Keychron P1 also lists Linux compatibility and includes extra keycaps for Mac modifiers.

According to the Keychron product description, the P1 Pro (wireless version) and the wired P1 offer a 1000 Hz polling rate in their 2.4 GHz and wired modes. The GravaStar Mercury K1's polling rate is not specified in the provided information.

The GravaStar K1 is better suited for travel than the Keychron P1. It is over 500 grams lighter (1080g vs 1650g) and has a larger battery, reducing the need to carry a charger. Its 75% layout is also space-efficient for packing.

Yes, the Keychron P1 is listed with multiple switch type options, including tactile switches. The vendor page shows options like Keychron Super Brown switches. The GravaStar K1, according to its metadata, is only listed with linear switches.

The Keychron P1 offers far more layout options. Its metadata supports ANSI, ISO, ISO-DE, ISO-ES, ISO-FR, ISO-Nordic, ISO-SW, and ISO-UK layouts. The GravaStar K1 is listed with a standard ANSI layout.

The GravaStar Mercury K1 uses a POM plate, while the Keychron P1 uses a polycarbonate (PC) plate. Different plate materials affect the typing sound and feel, with POM often providing a deeper, softer sound and PC offering a more resonant, clacky sound.

Yes, the Keychron P1 product description highlights an aluminum rotary encoder (knob) that is programmable for functions like volume control or zoom. The GravaStar Mercury K1 does not list a knob as a feature.
