USB 4.0 40 Gbps cable for power and video

This 1.5 ft USB 4.0 Type-C cable delivers up to 240 W of power and 40 Gbps bandwidth for charging, data and display. It suits users who connect laptops, docks, eGPUs or 8K monitors through a single port. Thunderbolt 3 and 4 hosts are supported. The short length keeps the desk tidy for stationary setups.

Thermals noise and power draw in normal use

The cable handles 48 V at 5 A without active cooling, so it stays cool during 240 W charging sessions. No fans or moving parts mean silent operation. Power loss over the 1.5 ft run is minimal, leaving nearly the full 240 W available at the device end. Data integrity holds at the rated 40 Gbps under sustained loads.

What this replaces and when the jump is worth it

It replaces slower 10 Gbps or 20 Gbps cables that limit 8K@60 Hz or dual 4K@60 Hz output and cap charging below 240 W. The upgrade matters when a single cable must carry 40 Gbps data, 8K video and maximum power simultaneously. Buyers whose hosts only support 20 Gbps or lower power will not see the full benefit.

Questions about this item

How do I plug this 1.5 ft USB 4.0 cable in so the 40Gbps link actually works?

Connect both USB-C ends to ports that support USB4 Gen3 or Thunderbolt 3/4; a USB 3.2 Gen2 port will limit bandwidth to 20Gbps.

Will the 240W charging capability degrade over time?

The cable is rated for 48V/5A continuously; no user maintenance is required unless the connectors or jacket show physical damage.

What stops the 40Gbps speed during a long transfer?

Sustained throughput is capped by the host controller and device storage; the cable itself supports the full 40Gbps Gen3 rate.
