Belkin RC21-01520100-R3U1 Power Supply White

Drag-Free Cable Control

The Belkin RC21-01520100-R3U1 is a mouse bungee designed for gamers who want to eliminate cord drag during play. An adjustable spring arm holds the cable at an optimal angle to prevent tangles and snags on the desk surface. The clip-on catch accommodates rubber, braided and paracord cables from major brands. It connects via a corded electric link to enable its lighting features.

Spring Arm Limits

The spring arm provides elevation and angular adjustment but has a fixed range of motion determined by its physical length and tension. Cables thicker than the catch opening or excessively stiff paracords may not feed smoothly through the rubber-coated clip. The device requires a USB connection for power, so an available port is necessary for the RGB underglow to function. It does not support wireless charging or data pass-through.

Desk Stability Headroom

A 240g weighted base combined with anti-slip rubber feet keeps the unit anchored during rapid mouse swipes. The compact footprint of 11.9888 x 13.8938 cm suits tight desk layouts while leaving room for keyboards and other peripherals. The 16.8 million colour RGB system offers eight addressable zones controllable through Razer Synapse 3 software on Windows, macOS, Linux and Chrome OS. Buyers needing a purely passive bungee without software dependency or USB power draw should consider simpler alternatives.
