GravaStar Mercury K98 Pro - Mechanical Gaming Keyboard - Phantom Black

The GravaStar Mercury K98 Pro - Phantom Black is a premium 98% mechanical gaming keyboard designed for high-performance gaming, productivity, and enthusiast desktop setups. A premium glossy aluminum alloy exoskeleton is used to create its distinctive cyber-inspired construction, while a compact 98-key layout is provided to retain essential functionality without requiring the footprint of a traditional full-size keyboard. A 1.65-inch TFT color display dashboard and multifunction control knob are integrated for added control and visual functionality.

High-speed performance is delivered through a true 8000Hz polling rate in both wired and 2.4GHz wireless modes. GravaStar Custom UFO Mechanical Switches are fitted for a smooth linear feel and are pre-lubed for consistent operation. A five-layer foam-dampened gasket mount structure is also used to improve typing acoustics and reduce unwanted keyboard noise.

Flexible connectivity is provided through 2.4GHz wireless, Bluetooth 5.4, and USB-C wired modes, allowing the keyboard to be used across different desktop and gaming configurations. An 8000mAh rechargeable battery is built in, with up to 228 hours of battery life provided in 1K mode with RGB switched off. Customization is further supported by 19 built-in ARGB backlight effects, four ARGB ambient side-light modes, and a driverless web-based driver platform.
