Overview

The GravaStar Mercury K1 Pro is a wireless mechanical keyboard that stands out with its alien-inspired design and hand-finished weathering paint. Its 75% layout saves desk space while retaining navigation keys, and the aluminum alloy body provides a cool, premium feel. The keyboard is powered by an immense 8000mAh battery, offering weeks of usage on a single charge.
Developed in collaboration with BSUN, the Speedy Mint linear switches feature a 1.2mm actuation point and 45g actuation force, making them ideal for both gaming and fast typing. A gasket mount structure with five layers of dampening delivers a quiet, responsive keystroke with a satisfying sound profile. The hot-swap socket supports 3- and 5-pin Cherry MX compatible switches, so you can customize the feel without soldering. With three connectivity options – 2.4GHz, Bluetooth 5.0, and USB-C wired – and support for up to three devices simultaneously, the Mercury K1 Pro fits seamlessly into multi-device setups.

Connectivity & Compatibility

The Mercury K1 Pro offers three connection methods: a low-latency 2.4GHz wireless mode (via included USB dongle), Bluetooth 5.0, and USB-C wired. It can remember up to three paired Bluetooth devices, allowing you to switch between a PC, tablet, and smartphone with a simple key combo. The keyboard is compatible with Windows, Mac, Android, and iOS, and a physical switch on the back instantly toggles between Windows and Mac key layouts.
Hot-swap support means you can replace the switches with any 3- or 5-pin Cherry MX compatible switch to tailor the feel to your preference. The keyboard uses a standard US ANSI layout, which is great for English speakers but might require adjustment for users accustomed to Japanese JIS layouts.

Product Info

Available since late 2024, the GravaStar Mercury K1 Pro retails for around ¥31,980 (tax included) on online retailers. It includes a USB-C to A cable, 2.4GHz dongle, keycap puller, switch puller, and extra keycaps. The keyboard carries a standard one-year manufacturer warranty. Market positioning is mid-high tier: it competes with enthusiast mechanical keyboards from major gaming brands but offers a distinct design language that appeals to users seeking something beyond the typical "gamer" aesthetic.

Best Use Cases

  • Aesthetic-focused gamers: If you've invested time and money into a custom PC setup with unique lighting and case design, the Mercury K1 Pro's organic shape and hand-applied weathering finish will become the centerpiece of your desk. It's a statement piece that also performs excellently in FPS and RTS games. However, if you prefer a minimalist, clean look, this keyboard might feel too busy.
  • Long-session typists and writers: The 8000mAh battery means you can work wirelessly for weeks without recharging. The light linear switches reduce finger fatigue during all-day typing sessions, and the gasket mount keeps the sound relatively quiet for shared workspaces. Yet, those who crave a tactile or clicky feedback should look elsewhere (or swap the switches).
  • Multi-device professionals: Switch between your work PC, personal tablet, and phone without unplugging or fumbling with cables. The Mercury K1 Pro's Bluetooth 5.0 range is excellent, and the ability to pair three devices simultaneously streamlines your workflow. Just note that the companion software is Windows-only, so Mac users cannot customize macros or RGB lighting via software.
