ATTACK SHARK X820 ULTRA Tri-Mode (2.4G/ Bluetooth/ USB-C) Wireless RGB Mechanical Gaming Keyboard
The Attack Shark X820 Ultra is a 75% wireless mechanical keyboard with a 0.85-inch TFT smart display that shows time, battery level, connection status, and RGB effects. A CNC metal knob scrolls menus and adjusts volume, brightness, and lighting speed with a short press for select. The keyboard connects over Bluetooth, 2.4G wireless, or USB-C wired, switching between up to 5 devices, and a 4000mAh battery extends play and work sessions. Pre-lubed linear switches sit on a 1.2mm FR4 dual-layer PCB with individual key slotting, and hot-swappable 3-pin and 5-pin sockets let you change switches without soldering. South-facing RGB runs 16.8 million colors with 19 preset effects, fully programmable through QMK. The compact 75% layout keeps 80 keys plus the control knob, with double-shot PBT keycaps in OEM profile.
