What will you mostly use it for?
The Keychron J3 SE wins for office and content creation work because its full number pad and quiet acoustic foam reduce friction. The Keychron V3 Max takes the lead for programming, travel, and modding thanks to its lighter weight, gasket mount, and screw-in stabilizers. Gaming is a tie since both deliver the same core wireless performance specs.
It's a tie
- Both offer a 1000 Hz polling rate on 2.4 GHz and wired modes for low latency.
- Both support N-Key Rollover in wireless and wired modes.
- Each has hot-swappable switches for personalizing feel, though the V3 Max includes factory-lubed Gateron Jupiter switches in fully assembled versions.

Keychron J3 SE vs V3 Max: your questions
Yes, the J3 SE comes with Mac/Win support. The vendor lists it as having a system toggle and an additional set of customized keycaps for both operating systems. It is also compatible with Linux.
The V3 Max is a standalone TKL keyboard and does not have a built-in number pad. However, because it supports QMK and VIA, you can pair it with a separate QMK-compatible number pad. It does not include a number pad module itself.
Both have a 4000 mAh battery. The J3 SE is rated for around 200 hours of use with backlight off, while the V3 Max is rated for up to 190 hours in the same condition. Real-world battery life will vary based on usage and screen brightness.
Yes, both the Keychron J3 SE and V3 Max have hot-swappable PCBs. They support most 3-pin and 5-pin MX mechanical switches, including Cherry, Gateron, and Kailh, allowing you to change switches without soldering.
The J3 SE has a 96% layout, which includes a number pad, arrow keys, and navigation cluster. The V3 Max has an 80% TKL layout, which omits the number pad but retains dedicated function row and arrow keys.
Yes, both keyboards feature RGB lighting. The J3 SE has north-facing per-key RGB with more than 22 backlight effects. The V3 Max has south-facing RGB LEDs. Both are configurable via QMK and VIA software.
It depends on preference. The J3 SE uses multiple layers of acoustic foam (IXPE, PET, EDPM) for a dampened sound, while the V3 Max uses a gasket mount and PC plate for a softer, more flexible typing feel. The J3 SE also offers three adjustable typing angles for ergonomics.
Yes, the V3 Max supports a knob (listed as 'Knob Support'), and the fully assembled version includes a knob. The knob can be programmed via QMK for functions like volume control or zooming.
Both keyboards have a 1000 Hz polling rate on 2.4 GHz and wired modes. In Bluetooth mode, the J3 SE drops to 125 Hz, while the V3 Max drops to 90 Hz.
The V3 Max is generally easier to mod. It has a gasket mount design, screw-in stabilizers, and is available as a DIY kit. The J3 SE is a pre-built keyboard with an ABS case and no gasket mount, limiting advanced modding options like case foam replacements.
