Universal USB4 Cable for High-Speed Workflows
This USB4 cable connects laptops, phones, tablets, SSDs, eGPUs and docking stations through a single USB-C link. It delivers up to 40Gbps bandwidth, 8K video output and 240W charging. Backward compatibility covers USB 3.2, USB 2.0 and Thunderbolt 3 and 4 standards.
Ideal for Professionals Needing Maximum Bandwidth
Creators moving large NVMe datasets, users driving dual 4K monitors at 60Hz and owners of 140W or 240W laptops gain full performance. Not suited for buyers whose devices lack USB-C video alt mode or PD 3.1 support, or who require longer reach than the supplied length.
40Gbps USB4 Bandwidth Decides Fit
The cable’s 40Gbps peak throughput matches the fastest USB4 hosts and peripherals; devices limited to 20Gbps USB4 or USB 3.2 Gen2 speeds will operate at their own lower ceiling. Choose this cable when the workflow demands the full 40Gbps pipe for storage, video or eGPU traffic.

Questions about this item
Will the 240W PD 3.1 EPR cable need replacement if the USB-C connectors loosen over time?
The cable is new and built to the USB4 Gen3 40Gbps standard; normal handling will not degrade the connectors, and no scheduled replacement is required.
What limits sustained 40Gbps throughput when the cable runs at full speed?
The 40Gbps ceiling is set by the USB4 Gen3 specification; actual throughput will not exceed this figure even with continuous large-file transfers.
Does the 5ft cable get hot or draw extra power during all-day 240W charging and 8K video?
The cable supports PD 3.1 EPR up to 48V/240W and 8K@60Hz video simultaneously; it is rated for that load without overheating or excess power draw.
