This article covers Keychron V3 Max QMKワイヤレス・カスタムメカニカルキーボード.

Overview

The Keychron V3 Max is a wireless TKL mechanical keyboard that brings high-performance connectivity to the V-series lineup. It supports three connection modes: 2.4GHz (with included USB-A/C receiver), Bluetooth 5.1, and USB-C wired, making it a versatile choice for gamers, programmers, and remote workers alike. One of its standout features is the 1000Hz polling rate over 2.4GHz wireless, which delivers latency comparable to a wired connection. The keyboard also fully supports QMK/VIA for key remapping and macros, giving users deep customization without proprietary software.

Connectivity & Compatibility

The V3 Max offers triple connectivity: 2.4GHz wireless (with a dual-USB receiver that works with both USB-A and USB-C ports), Bluetooth 5.1 (up to 3 paired devices), and USB-C wired. The Bluetooth mode is great for switching between a PC, tablet, and smartphone seamlessly. Operating system support covers Windows, macOS, and Linux. A dedicated system switch on the side lets you toggle between Mac and Windows layouts, and the package includes extra Mac modifier keycaps. No third-party software is required — all programming is done through the Keychron Launcher web app (VIA-compatible) via a browser.

Product Info

Released in 2024, the Keychron V3 Max sits in the mid-to-high tier of wireless mechanical keyboards, with a street price around ¥19,000–¥20,000 ( Japan price reference). It comes with Gateron Jupiter switches (Banana, linear) installed in hot-swap sockets, compatible with most 3-pin/5-pin MX-style switches. The keycaps are OSA-profile double-shot PBT, offering excellent oil resistance and long-lasting legends. The gasket-mount design and internal sound-dampening foam reduce typing noise and provide a softer, more cushioned feel. Warranty is one year from the manufacturer (may vary by retailer). Included accessories: USB-A and USB-C receiver dongles, USB-C to C cable, keycap puller, switch puller, extra Mac keycaps, quick start guide.

Best Use Cases

Gamers: The 2.4GHz wireless with 1000Hz polling ensures low-latency gameplay. The TKL form factor saves desk space for mouse movement. Not ideal if you need dedicated macro keys — consider a full-size or multi-button board. Programmers / Writers: QMK/VIA allows custom layers and macros for complex shortcuts. The relatively quiet typing feel helps during long coding or writing sessions. Remote Workers: Bluetooth multi-device switching lets you move between a work laptop and personal PC without re-pairing. However, 2.4GHz requires the included dongle, so Bluetooth-only devices won’t benefit from that mode. Custom Keyboard Beginners: Hot-swap sockets and a gasket mount make this a perfect introduction to the custom keyboard world — no soldering needed, and you can immediately feel the difference in typing experience.

Things to Consider

The V3 Max comes with a US ANSI layout by default — if you need Japanese JIS layout, you’ll have to source separate keycaps. Initial setup for QMK/VIA programming requires a wired connection. Some users have reported slight reconnection lag after sleep on older firmware versions, so updating to the latest firmware is recommended. Also, the plastic case is sturdy but doesn’t offer the premium feel of an aluminum chassis.
