Upgrade your gaming and productivity setup with the GravaStar Mercury K98 Pro Phantom Black, a premium 98% wireless mechanical gaming keyboard built for users who want full-size functionality in a more compact design. Its optimized 98-key layout retains the dedicated number pad while saving valuable desk space.
A built-in 1.65-inch TFT colour display provides a customizable dashboard for system information, keyboard settings, keystroke data, time and custom animations. The multifunction rotary control knob offers convenient access to volume, lighting and keyboard controls.
The K98 Pro features pre-lubricated GravaStar Custom UFO linear mechanical switches, engineered for smooth keystrokes, refined acoustics and durability of up to 70 million presses. Its hot-swappable PCB allows compatible mechanical switches to be replaced without soldering.
For competitive gaming, the keyboard supports a true 8000Hz polling rate in both USB-C wired and 2.4GHz wireless modes. This delivers ultra-responsive performance with latency as low as 0.1ms when wired and 0.4ms over 2.4GHz wireless.
The five-layer gasket-mounted acoustic structure combines PORON foam, an IXPE switch pad, PET film and slow-rebound dampening materials to reduce hollow resonance and produce a rich, comfortable typing sound.
Connect using high-speed 2.4GHz wireless, Bluetooth 5.4 or USB-C wired mode. The large 8000mAh rechargeable battery provides up to 228 hours of wireless use in 1K mode or up to 166 hours in 8K mode with RGB lighting switched off.
A glossy Phantom Black aluminium-alloy exoskeleton and customizable ARGB lighting complete its premium futuristic appearance. With 19 keyboard lighting effects and four ambient side-light modes, the GravaStar Mercury K98 Pro is ideal for gaming PCs, professional workstations, content creation and modern RGB desk setups.
