  • Extends USB-C reach by 6.6 ft with two cables included

What this cable does

This two-pack of USB-C male-to-female extension cables adds 6.6 feet of reach for charging, data and video. Each cable handles 10 Gbps transfer, 100 W power delivery and 4K 60 Hz display output. It suits laptop and tablet users who need extra length at a desk or on a nightstand.

Speed and power limits

The cable is rated for USB 3.1 Gen 2 at 10 Gbps and 20 V / 5 A for up to 100 W charging. Video requires both the host and the display to support USB-C alternate mode with a Gen 2 cable; a Gen 1 link will not pass 4K 60 Hz. The 35-minute 80 % charge example assumes a device and charger that both negotiate 100 W.

Installation notes

Plug the male end into the host port and the female end accepts your existing USB-C cable or peripheral. No drivers are needed. The most common issue is using a host port or peripheral cable that only supports USB 2.0 or 5 Gbps, which drops speed and disables video. Verify both sides are Gen 2 rated before blaming the extension.
