USB-C Extension Cable 3.3 ft 10 Gbps

This USB-C male-to-female cable extends a connection by 3.3 feet while supporting 10 Gbps data transfer and up to 100 W power delivery. It is built for users who need extra reach for a hub, charger, or external monitor without sacrificing speed.

Limits of USB 3.2 Gen 2 and video reach

The 10 Gbps ceiling applies only when both host and device support USB 3.2 Gen 2; older ports will fall back to lower speeds. Video output up to 4K at 60 Hz is possible, but the supplier notes signal attenuation beyond a total cable run of 10 feet, so longer chains may lose stability.

Replaces shorter fixed cables when distance matters

It upgrades a short captive cable on a dock, charger, or VR headset when the device sits farther from the port. The jump is worth it only if the combined length stays within the 10-foot video guideline and the host is not an active Thunderbolt 3 dock, which the cable does not support.

Questions about this item

Should I pick the 3.3 ft length or a longer cable for my desk setup?

The J-EC-33 is 3.3 ft (1 m) long. The supplier advises keeping the total cable run under 10 ft for stable 4K video and charging performance. Longer runs may cause signal loss.

What does the 10 Gbps rating actually deliver when I plug in an SSD?

10 Gbps is the maximum data rate supported by the USB 3.2 Gen 2 connection. Real-world transfer speed depends on the drive, host controller and file types, but the cable itself does not throttle below that ceiling.

Which USB standard does the Type C connector use and what does it limit?

The cable follows USB 3.2 Gen 2 (10 Gbps) and carries up to 100 W (20 V / 5 A) Power Delivery. It also supports 4K 60 Hz video alt mode. It will not work with active Thunderbolt 3 docks or hubs.
