What the cable is and who it serves

This USB4 extension cable adds 3.3 feet of reach between USB-C devices while supporting 40 Gbps data transfer, 240 W charging and single 8K or dual 4K video output. It is intended for users who need to extend a Thunderbolt 4, USB4 or high-power USB-C connection without losing bandwidth or charging speed.

Installation and common pitfalls

The male-to-female connectors plug straight in with no driver installation, but the female end is not reversible so it may need to be flipped if the connection feels loose. Keep the total combined cable run under 10 feet for stable 40 Gbps performance, and verify that every device, hub and cable in the chain supports the target resolution and bandwidth.

Practical limits of the USB4 interface

Bandwidth drops if the overall link exceeds 10 feet, and 8K or dual 4K video requires every component in the path to support those modes. Charging is capped at 240 W (48 V / 5 A), so devices demanding more power will not charge at full speed. Actual throughput always depends on the weakest link in the connected hardware.

Questions about this item

How do I verify the cable is delivering the full 40 Gbps throughput after connecting it?

Check that both the host and the peripheral support 40 Gbps, then keep the total combined cable length under 10 feet for a stable link.

What comes in the box and is anything else required to use the 240 W charging capability?

The box contains the 3.3 ft male-to-female USB-C extension cable; a 240 W capable charger and device are needed separately to reach 48 V / 5 A.

Which length version should I choose to maintain 40 Gbps and 8K video without signal loss?

The 3.3 ft model keeps the total run well within the 10 foot limit, preserving 40 Gbps data and single 8K or dual 4K output.
