Description

The Raiku R905 is a budget-friendly wireless gaming keyboard and mouse combo designed for both gaming and everyday productivity. It features a compact 87-key (tenkeyless/TKL-style) keyboard paired with an ergonomic mouse, sharing a single 2.4GHz USB receiver for easy setup and minimal USB port usage. It’s popular as an affordable entry-level option with RGB lighting, rechargeable batteries, and silent operation.

Design and Build
• Keyboard: Compact 87-key layout (no numpad for smaller footprint). Ergonomic design with foldable/tilt legs on the bottom for adjustable typing angle and comfort. Dimensions: approximately 359 × 132 × 35 mm. Sleek black finish with illuminated keys.
• Mouse: Ergonomic shape with 6 buttons (including left/right click, scroll wheel with rubber grip, and side buttons). Dimensions: approximately 130 × 72 × 41 mm.
• Weight: Lightweight overall (mouse around 62g in some descriptions, though exact keyboard weight varies).
• Durability/Features: Anti-ghosting support for multiple simultaneous key presses. Silent (ultra-quiet) membrane-style keys with good key travel (not mechanical). Power on/off switches on both devices. No wrist rest. The set is compact and portable, making it suitable for desktops, laptops, gaming setups, or travel.

Lighting
• Keyboard: RGB backlighting with rainbow/breathing effects. Supports 7 static color modes, 3 brightness levels, and rainbow flowing/breathing modes. Lights can be turned off to save battery.
• Mouse: RGB LED lighting (often described as gradually changing colors or breathing; limited customization in some units — cannot always switch individual colors).
Lighting adds a gaming aesthetic, especially useful in low-light environments.

Connectivity and Compatibility
• Wireless: 2.4GHz RF via a single shared USB dongle/receiver (stored in the mouse or included). Reliable connection with up to 10 meters (33 feet) range and low latency.
• No Bluetooth mentioned in most listings (primarily 2.4GHz only).
• Compatibility: Works with Windows (XP, 7/8/10/11), and some support for Mac. Plug-and-play — no drivers needed for basic use. Multimedia function keys for volume, playback, etc.

Performance and Features
• Keyboard: Membrane keys with decent travel and tactile feedback. Anti-ghosting. Multimedia shortcuts. Silent operation ideal for shared spaces or late-night use.
• Mouse: Optical sensor with 1200 DPI (some listings note adjustable DPI levels, e.g., 3 settings like 800/1600/2400 in similar models). 6 buttons total. Smooth scrolling and tracking for gaming or office work.
• Additional: Energy-saving mode (sleeps after inactivity, e.g., 2 minutes). No dedicated software/app for advanced customization in basic versions.
It’s not a high-end mechanical gaming board but offers solid performance for casual gaming, work, or mini-PC setups.

Battery and Power
• Keyboard Battery: Built-in 2000 mAh rechargeable lithium battery. Claims include up to 500 hours without backlight or around 50 hours at maximum brightness (real-world varies; users report weeks of use with occasional charging). Some tests mention 8+ hours continuous with lights on.
• Mouse Battery: Built-in 500 mAh rechargeable battery. Lasts several days to a week depending on use and lighting.
• Charging: USB-C port on both devices. Full charge in about 3 hours. USB-C cable included. Smart power-saving helps extend usage.
Battery life is a strong point for the price — many users charge infrequently.
