The Mercury K98 Pro from GravaStar arrives as the brand’s most ambitious wireless mechanical keyboard yet, blending industrial design with features that bridge gaming and professional workflows. Its 98% full-size footprint is paired with a 8000mAh battery, delivering up to 228 hours of use on a single charge when lighting is disabled—a figure that underscores its intent as an all-day peripheral.
At the heart of the design is a CNC-machined aluminum chassis that exposes internal structure in a signature cyberpunk aesthetic. The gasket-mount construction, compatible with both top and bottom mounting, contributes to a soft yet springy keystroke feel across the full 98-key layout. This mechanical foundation is paired with GravaStar’s proprietary UFO Linear switches, rated for 70 million keystrokes, and a five-layer acoustic dampening system that refines sound without muting it.
Wireless performance is a key differentiator. The keyboard supports an 8000 Hz polling rate over both wired USB-C and 2.4 GHz wireless connections, achieving response times of 0.1 ms when wired and 0.4 ms wirelessly. Tri-mode connectivity—2.4 GHz, Bluetooth 5.4, and wired—ensures seamless switching between environments without sacrificing responsiveness.
A built-in 1.65-inch TFT display (142 x 428 pixels) adds a layer of functionality rare in full-size mechanical keyboards. The screen provides real-time feedback and customizable on-screen content, configurable via a web-based driver that requires no local software installation. This feature, combined with per-key RGB backlighting—complete with 19 presets and music-reactive modes—extends the keyboard’s utility beyond input to include status displays, macros, or even media controls.
Lighting is further expanded with 3-side surround underglow and foot-halo ambient lighting, allowing users to extend visual customization to the edges of the chassis. All effects are saved in three onboard memory profiles, simplifying transitions between settings.
The Mercury K98 Pro is priced at $259 USD and is available through GravaStar’s global distribution network, covering over 50 countries. Its combination of battery life, polling rate, and display functionality positions it as a tool for users who demand both performance and personalization in a full-size form factor.
