Product identity

The Jansicotek USB4 cable connects USB-C devices with up to 240W power delivery and 40Gbps data bandwidth. It suits users who charge high-power laptops, drive 8K displays or move large files between Thunderbolt 3 and 4 hosts. It is not for buyers who need legacy USB-A connectors or longer runs beyond the supplied length.

Thermals noise power

The cable handles up to 48V at 5A for 240W charging without active cooling, so it runs silently in normal use. Power draw matches the attached device and charger, with no added overhead from the cable itself.

Upgrade context

It replaces older USB-C cables limited to 20Gbps or lower wattage, enabling single 8K@60Hz or dual 4K@60Hz video and 40Gbps Gen3 transfers. The jump is worth it when your host, charger and display all support USB4 or Thunderbolt 3 and 4 speeds.

Questions about this item

How do I plug this cable in, and what mistake should I avoid?

Connect the USB-C male ends to the host and device ports; the mistake is using a port limited to 20Gbps instead of the 40Gbps Gen3 port needed for full speed

What will wear out first and need replacement?

The cable itself — repeated bending near the connectors can fatigue the internal wires, so replace it if video drops or charging falls below 240W

What limit appears first during a long 40Gbps transfer?

Sustained writes hit the 2.1GB/s device ceiling before the cable's 40Gbps rating becomes the bottleneck
