Product information

Description

The A4Tech B820R Gaming USB Black is a full-size (100%) wired gaming keyboard that uses LK optic mechanical switch technology to deliver extremely fast key response and extended durability. The top panel is made of gunmetal aluminium alloy and the keyboard includes full N-key rollover, spill-resistant nano-coating, and a smart water flow system for improved protection and longevity. RGB backlighting offers preloaded effects and a self-customize mode with 16.8 million colors and shareable profiles.

Advantages

LK Optic Switch technology provides a 0.2 ms key response with zero digital latency and a reduced travel distance of 3 mm for 25% faster actuation compared with typical 4 mm metal switches. The switches are rated for over 100 million keystrokes. The keyboard supports full NKRO for simultaneous key presses, preloaded and user-customizable RGB animations with 16.8 million color options, and a corrosion-resistant aluminium top panel. Additional protections include an exclusive nano-coating over the PCB and a precision-engineered water drainage system.

Suitable for

  • Competitive and casual PC gaming where low input latency is critical
  • Long typing or streaming sessions that require durable keys and ergonomic design
  • Users who want customizable RGB lighting and the ability to share presets
  • Environments where occasional spills may occur thanks to nano-coating and drainage

Key specifications

  • Interface: USB
  • Form factor: Full-size (100%)
  • Switch type: LK Optic mechanical switch, 3 mm travel, 0.2 ms response
  • Switch life: >100 million keystrokes
  • NKRO: Full N-key rollover
  • Lighting: RGB, 16.8 million colors, 6 preloaded effects, customizable animations
  • Top panel: Gunmetal aluminium alloy
  • Protection: PCB nano-coating and smart water flow drainage system

How to use

Connect the keyboard to a PC using the USB interface; it will operate as a standard wired keyboard. Use the FN key combinations (for example FN + F12) to cycle through preloaded lighting effects without installing drivers. Create and store custom RGB animations using the FN + 0–9 slots and share profiles with other supported keyboards by following the keyboard’s preset storage procedure.

Usage recommendations

Keep firmware and host drivers up to date when available, avoid exposing the keyboard to prolonged direct liquid contact despite its nano-coating and drainage system, and use a stable surface to preserve the aluminium top panel finish and ensure optimal key performance.
