📱 1.65” Smart TFT Dashboard

Most keyboards have a status LED. The K98 Pro has a 1.65” TFT color display running at 142×428 OPX resolution. Use it to monitor real-time system stats, track keystrokes, swap between profiles, and watch dynamic sci-fi animations that match the Phantom Black aesthetic. It’s your desktop command center — functional, immersive, and unlike anything else in its class.

⚡ Dual 8KHz Polling Rate — Wired and Wireless

Most keyboards that claim 8KHz only deliver it over USB. The K98 Pro delivers a true 8000Hz polling rate in both wired and 2.4GHz wireless modes, cutting input latency to a near-instantaneous 0.1ms. Whether you’re plugged in for a tournament or running wireless for a ranked session, the K98 Pro never gives up its competitive edge. Bluetooth 5.4 is available for flexible everyday use.

🔮 GravaStar UFO Mechanical Switches

Developed in-house and co-engineered with Kailh, the GravaStar UFO Mechanical Switches are factory pre-lubed linear switches built for enthusiasts who don’t want to mod their keyboard before they can enjoy it. Smooth from the first keystroke, with a 45gf actuation force, 1.2mm pre-travel, and 3.5mm total travel — fast enough for competitive gaming, refined enough for all-day typing. Rated for 70 million keystrokes. Four sample switches from the GravaStar enthusiast pack are included so you can explore alternatives.

🔊 Pure “Thocky” Acoustics — No Modding Required

The K98 Pro’s 5-layer foam gasket mount is one of the most advanced acoustic systems in its price range:

• Poron Case Foam — Absorbs chassis resonance at the source
• IXPE Switch Pad — Dampens switch-level vibration for a cleaner sound profile
• PET Film — Adds structural rigidity while reducing flex noise
• Slow-Rebound Poron — Creates the soft, bouncy gasket feel that enthusiasts spend hours modding for
• Gasket-Mounted FR4 Plate — Holds each switch firmly while allowing the plate to flex naturally

The result: a deep, creamy thock right out of the box. No foam stuffing. No tape mod. No lubing. Just open the box and type.

🔋 228 Hours. Game Without Limits.

The 8000mAh rechargeable battery delivers up to 228 hours of wireless use in 1K polling mode with RGB off — or 166 hours in full 8K wireless mode. In practical terms, that’s weeks of daily gaming sessions between charges. When you do need to top up, the included USB-C braided cable handles it fast. Battery anxiety is not a feature of the K98 Pro experience.

🌐 Tri-Mode Connectivity — Your Setup, Your Rules

• 2.4GHz Wireless (8KHz) — The primary competitive mode. Lag-free, ultra-responsive, with the included high-speed wireless receiver
• Bluetooth 5.4 — Ultra-stable wireless for multi-device setups, laptops, and tablets
• USB-C Wired (8KHz) — Zero-latency wired connection with the included 1.6m premium braided Type-C cable

🎨 19 ARGB Effects + 4 Ambient Side-Light Modes

The K98 Pro’s RGB system goes beyond standard backlighting. 19 built-in ARGB backlight effects illuminate the Phantom Black keycaps from below, while 4 ARGB ambient side-light modes cast a glow across your desk surface. Configure every effect, color, and brightness level through the web-based driver — no software to install, no account to create. Just open your browser and customize.

💻 Zero Bloatware — Web-Based Driver Platform

The K98 Pro is configured entirely through GravaStar’s browser-based driver platform. Remap keys, program macros, tune RGB profiles, and adjust polling rate — all from any browser on any device. Settings save to onboard memory. No driver installations. No background processes. No bloatware eating your RAM.
