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.

Questions about this item

Which version of the Belkin RC21-01520100-R3U1 should I choose for a compact desk?

The single white model measures 11.9888 x 13.8938 x 16.4084 cm and weighs 0.399 kg, so it fits tight spaces while the 240 g weighted base keeps it planted.

What does the 16.8 million colour figure mean once the bungee is on my desk?

It gives you full RGB control across 8 lighting zones through Razer Synapse 3, letting you match or sync the underglow with other Chroma gear.

How does the USB connection limit what the device can do?

The corded electric link only powers the RGB lighting and spring-arm mechanism; it carries no data, so mouse signals still run through your mouse’s own cable.
