What this cable does

The SMUGDESK USB4 cable carries 40Gbps data, 240W power and 8K video over a 1.5FT USB C to USB C link. It meets the USB4 Gen 3x2 specification and supports PD 3.1 extended power range up to 48V/5A. Backward compatibility covers earlier USB and thunderbolt generations.

Who should buy it

Creators moving large media libraries between SSD enclosures and laptops will see the full 40Gbps throughput. Users charging 240W laptops or driving single 8K@60Hz or dual 4K@60Hz displays get the headroom they need. Buyers who only need 10Gbps or 100W charging can choose a less expensive cable.

Installation notes

Plug the reversible USB C connectors into host and device; no driver is required. The cable negotiates the highest common speed — 40Gbps with USB4 Gen3x2 ports, 20Gbps with Gen2 ports. Video output needs host support for DisplayPort Alt Mode; thunderbolt hosts work but may limit resolution or refresh rate.

Questions about this item

What charger do I need to reach the 240W rating on this cable?

A PD 3.1 charger that can supply 48V at 5A is required; the cable supports Extended Power Range and will negotiate the highest wattage both ends allow.

Will this cable work with my Thunderbolt 3 dock and 4K monitor?

Yes, the USB4 Gen 3x2 cable is backward compatible with Thunderbolt 3 and can drive a single 4K@120Hz or dual 4K@60Hz display when the host and dock support those modes.

How can I verify the cable is running at 40Gbps after I plug it in?

Check the host OS connection details or run a large file transfer; sustained throughput near 40Gbps confirms Gen 3x2 operation.
