USB4 40Gbps extension cable for laptops and hubs

This 3.3 ft USB4 extension cable complies with the USB 4.0 specification and reaches a maximum data transfer rate of 40 Gbps. It delivers up to 240 W of power through the USB PD 3.1 protocol at 48 V and 5 A. The cable supports video output up to 8K at 60 Hz and is backward compatible with lower resolutions such as 5K at 60 Hz and 4K at 144 Hz or 120 Hz. It is designed to extend and protect the USB Type-C connector on compatible laptops and hubs.

Bandwidth and power limits of the USB4 interface

The cable operates at the USB4 maximum of 40 Gbps, which is twice the throughput of Thunderbolt 3. Power delivery tops out at 240 W via PD 3.1, so connected chargers and devices must also support that profile to reach the peak. Video bandwidth allows 8K at 60 Hz, but higher refresh rates at 8K or uncompressed signals beyond the spec are not supported. Total cable length including any existing leads must stay within USB4 electrical limits to maintain full speed.

Plug-and-play installation

The cable connects directly between a host USB-C port and a peripheral or hub without drivers or configuration. Its 3.3 ft length adds reach but also adds insertion loss, so chaining multiple extensions may degrade signal integrity below 40 Gbps. The reversible Type-C plugs fit either orientation, yet tight port spacing on some docks can block adjacent sockets. Users should verify that both host and device support USB4 or Thunderbolt 3 to achieve the rated performance.

Questions about this item

Should I choose the 3.3 ft length or a different size?

The cable is supplied at 3.3 ft, which keeps signal quality high for 40Gbps data, 8K@60Hz video and 240W charging without extra loss.

What does 40Gbps mean when I plug it into my laptop?

It allows up to 40Gbps real-world throughput for file transfers and dock bandwidth, double the 20Gbps ceiling of Thunderbolt 3, provided both host and device support USB4.

Does the USB4 interface limit charging or video in practice?

The USB4 connection carries PD 3.1 at 48V/5A for 240W charging and drives 8K@60Hz, 4K@144Hz or 4K@120Hz displays without compression.
