GravaStar Mercury K1 75% Mechanical Gaming Keyboard, Stealth Black, Tri-Mode Wireless

The GravaStar Mercury K1 – Stealth Black is a 75% mechanical gaming keyboard that keeps a function row, navigation controls and a rotary knob in a desk-friendly 79-key layout. Its aluminum-alloy frame, gasket-mounted structure and five-layer dampening suit gamers and typists who want a substantial build with flexible wired and wireless connectivity.

Key Features

• 75% 79-key layout with knob: retains useful controls while taking less desk space than a full-size keyboard.
• GravaStar custom linear switches: rated at 40gf actuation force, 1.5mm pre-travel and 3.5mm total travel.
• Tri-mode connectivity: use wired USB-C, Bluetooth 5.0 or the included 2.4GHz Type-A receiver.
• 8000mAh rechargeable battery: designed for extended wireless use; runtime varies with lighting and connection settings.
• Aluminum-alloy frame and gasket mount: supported by five-layer PORON foam dampening.
• RGB lighting: dual lighting systems with customizable standard and sound-reactive effects.

Important tradeoff: the compact 75% layout omits the dedicated number pad found on a full-size keyboard.
