What this cable is and who it targets

This SMUGDESK USB4 cable carries 240W of power and 40Gbps of data between two USB-C ports. At 1.6ft it is built for desktop set-ups where a laptop, monitor or high-power peripheral sits close to the host. The Extended Power Range profile lets a 140W MacBook Pro charge at full speed when paired with a matching 240W EPR PD 3.1 charger.

Who should use it and who should not

Creators moving 8K@60Hz or dual 4K@60Hz video streams, engineers transferring multi-gigabyte datasets at up to 2500MBps, and owners of 140W-class laptops gain the headroom they need. Buyers whose devices only support lower Power Delivery revisions or sub-40Gbps signalling will not reach the cable’s maximum throughput or wattage.

The spec that decides fit

The single figure that determines whether this cable is the right part is the 40Gbps USB4 Gen 3x2 data rate combined with 48V/5A Extended Power Range delivery. If the host and peripheral both negotiate USB4 Gen 3x2 and PD 3.1 EPR, the cable delivers its full 240W and 40Gbps; otherwise it falls back to the highest mutually supported speed and power level.

Questions about this item

How do I install the 1.6ft USB C to USB C cable and what step do people miss?

Plug the reversible USB C male connectors into both devices; the step people miss is confirming that the host and peripheral both support USB4 Gen 3x2 and PD 3.1 EPR so the 240W and 40Gbps ratings actually activate.

What maintenance or replacement will the 240W USB4 cable need later?

No scheduled maintenance is required; replace the cable only if the connectors become loose, the jacket shows damage, or a future device demands a longer reach than the 1.6ft length.

What limit appears first on the 240W USB4 cable during sustained 40Gbps transfers?

The 1.6ft length and 5A current ceiling keep thermals low, so the first limit is usually the connected device's own thermal throttling or controller ceiling rather than the cable itself.
