Keychron J8 HE vs LemoKey P1 HEWired 8K vs Wireless Aluminum

The J8 HE is a wired-only keyboard with an 8000 Hz polling rate and a plastic case, while the P1 HE adds 2.4 GHz and Bluetooth connectivity inside a full metal aluminum case. The P1 HE also includes a 4000 mAh battery rated for up to 100 hours with backlight off. Both are 75% gasket-mounted boards with hot-swappable magnetic switches.

The Keychron J8 HE lists an 8000 Hz polling rate, adjustable among 1000 Hz, 4000 Hz and 8000 Hz through the Keychron Launcher web app. The LemoKey P1 HE runs at 1000 Hz in both wired and 2.4 GHz modes, and drops to 125 Hz over Bluetooth. Buyers prioritizing raw polling should look at the J8 HE.

Yes, the P1 HE supports 2.4 GHz, Bluetooth 5.2 and wired Type-C connections. The vendor states it can hold up to 3 device wireless connections with on-the-fly switching. Bluetooth operating distance is listed as within 10 meters in open space.

No, the J8 HE is wired-only through a Type-C connection, using a Type-A to Type-C cable. The vendor describes an 8000 Hz polling rate out of the box in Type-C wired mode. Anyone needing wireless should consider the P1 HE instead.

The J8 HE ships with pre-lubed Keychron Ultra-Fast Lime Magnetic Switches made from POM. The P1 HE ships with Gateron Double-Rail Magnetic Nebula Switches that use Hall Effect sensors. Both are magnetic switch designs with adjustable actuation.

The J8 HE supports hot-swapping with Keychron Lime and Gateron Jade magnetic switches. The P1 HE is hot-swappable but the vendor states it is compatible exclusively with Gateron Double-Rail Magnetic Switches and does not support Gateron Magnetic Jade or KS-20 switches. That makes the J8 HE the more flexible option for trying different magnetic switches.

Yes, the P1 HE lists Rapid Trigger and adjustable actuation from 0.2 to 3.8 mm with 0.1 mm sensitivity. It also supports Dynamic Keystrokes 4-in-1 action keys and an analog mode, with Last Keystroke Prioritization and Snap Click disabled by default but enabled in the Lemokey Launcher web app. The J8 HE likewise offers adjustable actuation via the Keychron Launcher.

The Keychron J8 HE weighs 956g, according to the vendor specification. The LemoKey P1 HE weighs 1630g in its fully assembled form, reflecting its full metal aluminum body. The P1 HE's weight suits a fixed desk setup more than frequent travel.

Only the LemoKey P1 HE has a battery, a 4000 mAh unit rated by the vendor for up to 100 hours with the backlight off and around 5 hours of charging time. The J8 HE has no battery because it is wired-only. For cable-free use, the P1 HE is the only option of the two.

Both are listed with QMK and VIA support, and both offer web-based configurators, the Keychron Launcher for the J8 HE and the Lemokey Launcher for the P1 HE. The P1 HE also notes that its VIA keymap requires importing a JSON file while GitHub approval is pending. The J8 HE uses a 1 MB flash chip, while the P1 HE uses an ARM Cortex-M4 with 256KB flash.

The P1 HE is the more travel-friendly choice because it offers Bluetooth 5.2 and 2.4 GHz wireless plus a 4000 mAh battery. The J8 HE is wired-only and requires a Type-C cable wherever you go. That said, the P1 HE's 1630g aluminum body is heavier than the 956g J8 HE, so both are best treated as desk boards.

Both use Cherry profile double-shot PBT keycaps. The J8 HE offers three adjustable typing angles at 4, 8 and 10 degrees, while the P1 HE lists a 5.5 degree angle. The J8 HE also includes an extra set of Mac and Windows keycaps, and the P1 HE offers shine-through and non-shine-through keycap versions.
