- Wireless connectivity via 2.4 GHz and Bluetooth 5.2, with a large 4000mAh battery for extended use.
- Advanced magnetic switch features including Dynamic Rapid Trigger, 4-in-1 action keys, and Analog Mode for gaming.
- Significantly heavier than the J2 HE at 1630g, which is less portable.

“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.”

Keychron J2 HE vs LemoKey P1 HE: your questions
No, the Keychron J2 HE is a fully wired keyboard. Its connectivity is limited to Type-C USB only, as confirmed by the product listing. It lacks Bluetooth or 2.4 GHz wireless capabilities.
The Keychron J2 HE focuses on wired speed with an 8000 Hz polling rate in a lightweight plastic case. The LemoKey P1 HE, on the other hand, offers a premium full metal build, wireless connectivity (2.4 GHz and Bluetooth), and more advanced gaming features like Rapid Trigger and Analog Mode.
Yes, the LemoKey P1 HE is listed as having Mac/Win support. The product description also mentions extra complimentary keycaps for Mac layouts, and it is compatible with the Keychron Launcher web app which works on macOS.
The Keychron J2 HE has a higher polling rate of 8000 Hz when connected via its wired Type-C connection. The LemoKey P1 HE has a 1000 Hz polling rate in both wired and 2.4 GHz wireless modes.
Yes, both keyboards are hot-swappable. The J2 HE is compatible with Hall Effect magnetic switches. The P1 HE is also hot-swappable, but it is specifically compatible only with Gateron Double-Rail Magnetic Switches.
The primary difference is the case material. The Keychron J2 HE has a plastic case, making it lighter at 780g. The LemoKey P1 HE features a full metal aluminum body, resulting in a much heavier weight of 1630g and a more premium, rigid feel.
Yes, both keyboards support macro creation. They are programmable through a web-based Launcher app (Keychron Launcher for J2 HE, Lemokey Launcher for P1 HE) and also support QMK and VIA firmware for advanced customization and key remapping.
The LemoKey P1 HE is better for a clutter-free desk because it offers wireless connectivity through both Bluetooth 5.2 and a 2.4 GHz connection. The Keychron J2 HE is wired-only, which requires a cable to be connected to your computer at all times.
These keyboards do not require traditional software downloads. They are configured entirely through a web-based Launcher app (Keychron Launcher for the J2 HE, Lemokey Launcher for the P1 HE), which works in Chrome, Opera, or Edge browsers.
The Keychron J2 HE uses plate-mounted stabilizers for the larger keys. The LemoKey P1 HE uses upgraded screw-in PCB stabilizers, which are generally considered to offer more stability and a better sound profile.
Yes, the LemoKey P1 HE is described as having an Analog Mode. This allows for variable inputs based on how far you press a key, enabling more nuanced control in games and simulations that support analog input.
The Keychron J2 HE is much better suited for travel and LAN parties. It is significantly lighter (780g vs 1630g), has a plastic case that is less likely to dent, and requires only a simple USB cable for operation without the need to manage a battery.
