This article covers CORSAIR K100 AIR Ultra-Thin ワイヤレスゲーミングキーボード 薄型メカニカルキーボード ブラック かな印字なし CHERRY MX軸 CH-913A01U-JP1.

Overview

The CORSAIR K100 AIR is a wireless gaming keyboard that measures just 11mm at its thinnest point, making it one of the slimmest mechanical keyboards on the market. It uses CHERRY MX Ultra Low Profile Tactile switches, which offer an actuation point of only 0.8mm — significantly shorter than standard MX switches — enabling extremely fast keystrokes without sacrificing the satisfying tactile bump that many gamers and typists prefer.
This keyboard is aimed at users who want a premium typing and gaming experience in a low-profile form factor that blends into a clean, minimalist desk setup. It supports triple connectivity (2.4GHz SLIPSTREAM WIRELESS, Bluetooth 4.2, and USB-C wired), an 8,000Hz polling rate for ultra-low latency, and per-key RGB lighting controlled via CORSAIR iCUE software. The K100 AIR is a full-size (108-key Japanese layout) keyboard with a numeric keypad, yet it occupies less vertical space than many tenkeyless boards.

Connectivity & Compatibility

  • Wireless options: 2.4GHz SLIPSTREAM WIRELESS for gaming-grade low latency (1ms claimed), Bluetooth 4.2 for multi-device convenience, and wired USB 3.0 Type-A for zero-lag operation and charging.
  • The SLIPSTREAM adapter supports up to three devices simultaneously via a single dongle, though the K100 AIR itself can only be actively paired with one device at a time.
  • Compatible with: Windows, Linux, and Bluetooth-capable devices such as smartphones and tablets. Note that macOS is not officially supported, and some iCUE features may be limited under Linux.
  • The USB cable is detachable and can be stored easily, making travel more practical.

Product Info

The K100 AIR launched in late 2022 and sits at the high-end of the ultra-slim mechanical keyboard segment. With a typical street price around ¥30,000 (roughly $200 USD), it competes directly with other premium low-profile boards like the Logitech G915 and Razer DeathStalker V2 Pro. The key differentiator is the CHERRY MX Ultra Low Profile switch — a genuine Cherry switch in a package only about half the height of a standard MX switch.
Warranty: 2 years (varies by region). Accessories include the SLIPSTREAM wireless receiver, a USB Type-A to Type-C cable, quick-start guide, and warranty card. The Japanese-layout model (CH-913A01U-JP1) features 108 keys without kana legends, offering a clean look for users who don't need printed kana.
Market positioning: This is a no-compromise ultra-slim keyboard that sacrifices very little in terms of performance or features. It targets discerning gamers and professionals who value desk aesthetics and ergonomics just as much as raw gaming specs.

Best Use Cases

  • Competitive gamers who want a low-profile mechanical feel: The 0.8mm actuation point and tactile feedback allow for rapid, precise inputs. The 8,000Hz polling rate over SLIPSTREAM wireless means latency is practically indistinguishable from a wired keyboard. However, those who prefer deeper travel (2mm+) or linear switches may find the tactile bump here too subtle.
  • Minimalist desk setup enthusiasts: At 11mm thick, the K100 AIR virtually disappears on a desk, especially when paired with a low-profile wrist rest. Wireless operation eliminates cable clutter. On the downside, the full-size layout means it still takes up significant desk width; if space is at an absolute premium, a 75% or TKL board might be a better fit.
  • Multi-device workers: Quickly switch between a gaming PC, a work laptop, and a tablet using the dedicated device keys. The Bluetooth 4.2 connection is stable for office tasks and typing. But note: Bluetooth mode disables the 8,000Hz polling rate and some iCUE effects, so it’s not ideal for competitive gaming while on Bluetooth.
  • Traveling professionals needing a full-size board: Lightweight (780g) and flat, the K100 AIR fits easily into most laptop bags. iCUE’s onboard memory stores up to 8MB of profiles, so custom macros and lighting follow the keyboard anywhere without needing the software installed. Still, if absolute portability is the goal, a 60% or 65% keyboard would be lighter and take up less bag space.
