A 0.5 m USB-C cable delivering 40 Gbps data, 240 W charging and 8K 60 Hz video for all USB-C devices

Cable Length 1.6 Feet

  • Charge at up to 240W with PD 3.1 protocol

What this cable delivers

The SMUGDESK USB4 cable carries 40Gbps data, 240W charging and 8K@60Hz video over a .5 metre link. It suits owners of Thunderbolt 3 or 4 laptops, docking stations and high-resolution monitors who need one lead for every role.

The spec that decides fit

Full 40Gbps bandwidth is only available on USB 4.0 Gen3 or Thunderbolt 4 ports; Gen2 ports top out at 20Gbps. Buyers whose hosts stop at 10Gbps or 20Gbps will not see the rated throughput.

Thermals noise and power

Passive construction means no fan noise and no active cooling required. The aluminium-alloy and braided-nylon jacket handles the 48V 5A current without measurable heat rise during sustained 240W charging or 40Gbps transfers.

Questions about this item

What does the 40Gbps rating actually deliver when I plug this cable into my laptop and drive?

The cable supports up to 40Gbps with USB4 Gen3 ports, dropping to 20Gbps with Gen2 ports; real-world throughput depends on the host and device controllers.

Which charging standard does the 240W figure rely on, and what limits it in practice?

It uses USB PD 3.1 at 48V/5A; actual power is negotiated between the charger and device, so a lower-wattage brick will deliver less.

What clearance do I need for the 0.5m cable and its connectors in a tight dock setup?

The cable is 0.5m (1.64ft) long with USB-C plugs on both ends; the braided nylon jacket adds minimal bulk for routing.
