Overview

The GravaStar Mercury K1 is a wireless mechanical keyboard with a clean white design and a 75% layout (tenkeyless). It saves desk space while retaining function keys and arrow keys. The aluminum alloy frame provides a premium feel and stable typing experience, and the 8000mAh battery ensures long wireless usage.

Key Features

  • Custom Cherry Pink Linear Switches — Developed with BSUN, these linear switches have a 1.6mm actuation point and 40g actuation force, offering a light and fatigue-free typing feel. Rated for approximately 70 million keystrokes.
  • Gasket Mount with 5-Layer Sound Dampening — Absorbs typing impact and produces a pleasant, muted "thock" sound. Suitable for quiet offices or late-night use.
  • Hot-Swap Compatible — Supports Cherry MX-compatible 3-pin and 5-pin switches. Swap switches without soldering to customize your typing feel.
  • Tri-Mode Connectivity — 2.4GHz (via USB dongle), Bluetooth 5.0, and USB-C wired. Easily switch between Windows and Mac with the rear toggle.
  • 130 RGB LEDs — Independently customizable backlight and side lighting. Create custom animations using the dedicated software.
  • Volume Control Roller — Conveniently adjust volume with a roller on the right side.

Compatibility and Usage Notes

Cautions
