240W USB4 Charging Cable

The SMUGDESK USB4 cable delivers up to 240W at 48V/5A for rapid charging of compatible laptops such as MacBook Pro models. It suits users who need a single cable to power high-draw devices and move large files between USB-C hosts and peripherals.

40Gbps Data and 8K Video

Rated for 40Gbps transfer, the cable handles demanding workflows like external SSD arrays and eGPU enclosures when both ends support the speed. It drives a single 8K or 6K display at 60Hz, or two 4K monitors using separate cables, but cannot exceed the bandwidth ceiling of the connected hardware.

Thunderbolt 4 and Legacy USB Support

The cable works with Thunderbolt 4 and 3 hosts and remains backward compatible with USB 3.2, 3.1 and 3.0 ports, though speeds drop to the lowest common standard. It will not provide 40Gbps or 240W on older USB-C ports that lack Power Delivery 3.1 or Thunderbolt certification.

Questions about this item

Will the 40Gbps data rate work with my existing Thunderbolt 3 dock?

Yes, the cable is backwards compatible with Thunderbolt 3 and USB 3.2, 3.1, 3.0, so it will operate at the highest speed both devices support.

How can I confirm the 8K@60Hz video output is active after connecting my monitor?

Check your display settings to verify the resolution reads 8K or 6K at 60Hz; the cable carries the signal but the host and monitor must both enable the mode.

Does the 5ft cable include a power adapter for the 240W charging capability?

No, only the USB C to USB C cable is supplied; you need a 240W-capable GaN charger or power source to deliver up to 48V/5A.
