This article covers 【国内正規品】Keychron K4 Version2 ホットスワップ対応ワイヤレス・ゲーミングメカニカルキーボード 100キー.

Overview

The Keychron K4 Version2 is a 96% layout mechanical keyboard that packs full-size functionality—including a number pad and function row—into a compact chassis roughly 37 cm wide. It's an excellent choice for users who need a numpad but want to reclaim desk space for mouse movement or other peripherals. This model comes pre-installed with Gateron G Pro Red linear switches and features a hot-swappable PCB, so you can swap switches without soldering. It supports both USB-C wired and Bluetooth 5.1 wireless connections, with the ability to pair up to three devices and switch between them on the fly. The keycaps are made of PBT plastic, which resists shine and wear far better than ABS over long-term use.

Connectivity & Compatibility

The K4 V2 offers two connection modes: USB-C wired and Bluetooth 5.1 wireless. In wired mode, it supports full N-key rollover (NKRO), ensuring every keystroke registers accurately during gaming or fast typing. In wireless mode, it supports 6-key rollover, which is sufficient for everyday productivity and casual use. Compatibility spans Windows, macOS, iOS, and Android. A physical switch on the side lets you toggle between Windows and Mac layouts, automatically remapping modifier keys. The included USB-C cable can be used for both data and charging, so you can keep typing even when the battery runs low.

Product Info

The Keychron K4 Version2 is a mid-range mechanical keyboard that balances compact dimensions with full-size functionality. It was released as a revision of the original K4, addressing earlier feedback with improved Bluetooth stability and a more robust aluminum frame. The keyboard comes with a 1-year manufacturer warranty. In the box you'll find the keyboard, a USB-C cable, a keycap puller, a switch puller, and a few extra keycaps. It's widely available through Japan and other major online retailers, typically priced between ¥15,000 and ¥20,000.

Best Use Cases

Space-conscious number crunchers: If your workflow demands a numpad—accounting, data entry, spreadsheet work—the 96% layout keeps all the keys you need while cutting about 15% off the width of a full-size board. This lets you bring your mouse closer, reducing shoulder strain. Just be aware that the tighter key spacing may cause occasional typos if you have larger hands. Switch tinkerers and DIY enthusiasts: The hot-swappable PCB accepts any 3-pin or 5-pin MX-compatible switch, so you can experiment with different tactile, clicky, or silent switches without soldering. The process takes minutes and requires no special tools. However, non-MX-compatible switches (e.g., optical or Alps) won't work. Multi-device power users: Pair up to three devices via Bluetooth and switch between them with a key combination. This is ideal if you juggle a desktop PC, a MacBook, and a tablet on the same desk. Wired mode is also available for low-latency gaming or when you need to charge the battery. Note that wireless response is slightly slower than wired, so competitive FPS players should stick to the USB-C connection. Quiet-office typists: Gateron G Pro Red switches are linear and relatively quiet, making them a good fit for open-plan offices or shared workspaces where noise is a concern. If you find them too light, consider swapping to heavier linear switches like Gateron Black or silent linear variants for a more substantial feel.
