What will you mostly use it for?
For pure gaming speed, the J8 HE's 8000 Hz polling rate and magnetic switches give it an edge over the P1's standard 1000 Hz polling. In office and travel scenarios, the J8 HE's lighter plastic construction is more portable, while the P1's wireless capability and aluminum build offer a more premium stationary experience. For programming and content creation, both keyboards are equally matched with powerful programmability and a functional layout. Modding enthusiasts will favor the P1 for its aluminum case, standard switch ecosystem, and enthusiast-friendly components like screw-in stabilizers.
Pick the Keychron J8 HE
- 8000 Hz polling rate vs 1000 Hz for lower input lag.
- Magnetic switches allow adjustable actuation point via Launcher.
- Lighter weight (956g) for easier repositioning during fast gaming sessions.

Keychron J8 HE vs Lemokey P1: your questions
The Keychron J8 HE has a significantly higher polling rate of 8000 Hz, which can be adjusted down to 1000 Hz or 4000 Hz via the Launcher web app. The Lemokey P1 operates at 1000 Hz in wired and 2.4 GHz modes, and 90 Hz over Bluetooth. The J8 HE's 8K rate is a key advantage for competitive gaming.
Yes, both keyboards support full programmability. The J8 HE uses the Keychron Launcher web app, while the Lemokey P1 is compatible with both the Lemokey Launcher and VIA. Both allow remapping of keys, creation of macros, and adjustment of lighting and knob functions, though the P1 requires a JSON file to work with VIA.
No, the Keychron J8 HE is designed exclusively for magnetic switches. The vendor states it supports hot-swapping with Keychron Lime and Gateron Jade magnetic switches. It does not accept standard 3-pin or 5-pin MX-style mechanical switches.
The Keychron J8 HE is better for travel due to its lighter weight of 956g and smaller overall dimensions. The Lemokey P1, with its full aluminum case, weighs at least 1650g, making it much more cumbersome to transport in a bag.
Yes, the Lemokey P1 is available in a Pro version (P1 Pro) that supports 2.4 GHz, Bluetooth 5.1, and wired USB-C connectivity. The standard P1 version is wired only. The vendor description specifies this distinction clearly.
Both keyboards come with Cherry profile double-shot PBT keycaps from the factory. The vendor describes the J8 HE's keycaps as non-shine-through, while the Lemokey P1's keycaps are also specified as non-backlight shine through.
The Lemokey P1 features screw-in PCB stabilizers, which the vendor states minimize rattle and wobble for keys like the space bar and shift. The Keychron J8 HE uses plate-mounted stabilizers, which are generally considered less stable and more prone to rattle than screw-in stabilizers.
The Keychron J8 HE uses a plastic case material. The Lemokey P1 is constructed with a full CNC machined 6063 aluminum frame, which the vendor describes as being completed through a process involving CNC machining, polishing, anodizing, and sandblasting.
No, the Keychron J8 HE is a wired-only keyboard. The metadata and vendor description both list its connectivity as wired, with no support for Bluetooth or 2.4 GHz wireless. The Lemokey P1 offers wireless options on the Pro version.
Based on the provided relative scores, the Lemokey P1 scores higher in customizability (97.1 out of 100) compared to the Keychron J8 HE (92.5 out of 100). The P1 supports standard MX-style switches and offers a barebones kit, making it more flexible for builders and modders.
Only the Lemokey P1 Pro version has a battery, specified as a 4000 mAh rechargeable li-polymer battery. The Keychron J8 HE is wired-only and does not contain a battery. The vendor indicates the P1 Pro can provide up to 200 hours of use with backlighting off.
