“Worked perfectly, best keyboard I've ever owned. For one hour. After that all RGB turned off, and the main function of the keyboard (Typing), no longer works. I can't type with it, the web launcher doesn't detect it either, just don't waste your money.”

“Oh my. I think this is the perfect keyboard. I had a Keychron Q6 Max, but found it to be just too big and unwieldy. Then I tried a Keychron Q2 Max, and loved the size, but didn't like the south facing backlighting, as it just doesn't work with shine-through…”

Keychron J2 HE vs Lemokey P2 HE: your questions
The Keychron J2 HE has a higher polling rate of 8000 Hz, as stated in its specifications and vendor description, which is designed for minimizing input lag in competitive gaming. The Lemokey P2 HE has a polling rate of 1000 Hz in both wired and 2.4 GHz wireless modes.
No, the Keychron J2 HE is a wired-only keyboard. It connects via a USB-C cable and does not have any wireless functionality. The product metadata explicitly lists its connectivity as 'Wired;Wired only'.
Both keyboards use Hall Effect magnetic switches, but they are different models. The J2 HE uses Keychron's proprietary 'Ultra-fast Lime Magnetic Switch'. The Lemokey P2 HE uses the 'Gateron Double-Rail Magnetic Switch', which the vendor notes is the only compatible switch for that keyboard.
The Lemokey P2 HE is designed with modders in mind, featuring a tool-free screwless case with magnetic latches for easy disassembly. It also uses screw-in PCB stabilizers and includes multiple layers of foam (3mm acoustic, 4mm EPDM, PET film), which are common points of customization.
The keyboards have very different constructions. The Lemokey P2 HE boasts a 'full metal body' contributing to its 1430g weight and a premium, durable feel. The Keychron J2 HE uses a 'plastic' case, making it much lighter at 780g, but potentially less sturdy or premium-feeling.
Yes, both keyboards support extensive key remapping and customization. According to the vendor descriptions, both are compatible with QMK and VIA firmware. Additionally, each has its own proprietary web-based launcher (Keychron Launcher for the J2 HE, Lemokey Launcher for the P2 HE) for adjustments.
The Keychron J2 HE is lighter at 780g and has a 75% layout, but it is wired-only. The Lemokey P2 HE is much heavier at 1430g but smaller in footprint (65%) and offers Bluetooth and 2.4 GHz wireless connectivity. For portability where a cable is an issue, the P2 HE wins; for pure carry weight, the J2 HE is easier.
Yes, the vendor description for the Lemokey P2 HE states it is compatible with Windows, macOS, and Linux. It also comes with extra keycaps to fit Mac layouts. The Keychron J2 HE is also listed as compatible with both Windows and macOS.
Both keyboards come with Cherry Profile keycaps made from durable PBT plastic. The J2 HE uses 'Cherry Profile Double-shot PBT keycaps'. The P2 HE offers options for 'Cherry Profile Shine-Through' or 'Non-Shine-Through Double-Shot PBT keycaps'.
The Lemokey P2 HE has a 4000mAh rechargeable battery. According to the vendor specs, with the backlight off, it can last up to 100 hours. It takes around 5 hours to fully charge via USB-C.
