SMUGDESK USB4 Cable 40Gbps 240W 8K 5ft Thunderbolt 3/4 Compatible

SKU CH-3F0P-2KJJC

A 5 ft USB cable delivering 40 Gbps data, 8K 60 Hz video and up to 240 W charging for Thunderbolt 3 and 4 devices

Cable Length 5 Feet

  • Charges up to 240W with PD 3.1
  • Transfers data at 40Gbps maximum speed
  • Drives 8K@60Hz or dual 4K@60Hz displays
  • Works with Thunderbolt 3 and Thunderbolt 4 hosts
  • Backward compatible with all USB-C devices

One Cable for Every USB-C Device

This five-foot USB4 cable carries up to 240W of power and 40Gbps of data, so a single lead can charge phones, tablets and gaming laptops while also driving an 8K display. It works with any USB-C port, from the smallest accessory to the most power-hungry notebook.

Bandwidth and Power Depend on the Port

The cable is rated for 40Gbps Gen3 speeds, yet a Gen2 port will limit transfers to 20Gbps. Likewise, 240W charging at 48V/5A only occurs when both the charger and the device support PD 3.1; lesser adapters at 170W, 140W, 120W, 100W, 65W or 18W will negotiate their own lower profiles.

Simple Plug-and-Play With One Common Pitfall

Both ends are standard USB-C, so installation is a matter of connecting the two devices — no drivers or orientation fuss. The usual mistake is expecting 40Gbps or 240W from a port that only speaks Gen2 or an older PD revision, which the cable cannot override.

Questions about this item

Should I choose this 5 ft cable or a different length for my desk setup?

This model is supplied at 5 ft. If you need a longer or shorter reach, check whether the shop stocks other lengths of the same 40 Gbps, 240 W specification.

What does the 40 Gbps rating mean when I copy files between my laptop and an external SSD?

You can reach up to 40 Gbps with a USB4 Gen3 port, or up to 20 Gbps with a Gen2 port. The cable itself does not limit the speed below those ceilings.

Does the USB4 interface cap the 240 W charging or 8K video in any way?

The cable supports the full USB4 40 Gbps bandwidth, 240 W (48 V / 5 A) power delivery and 8K at 60 Hz or dual 4K at 60 Hz simultaneously.
