Jansicotek USB4 Thunderbolt 4 Cable 40Gbps 240W

This Jansicotek cable is a USB C to USB C cable built to the USB4 and Thunderbolt 4 specifications. It carries up to 240W (48V/5A) for fast charging and moves data at up to 40Gbps. The grey cable also drives an 8K display at 60Hz or two 4K displays using two cables.

Suits users who need one cable for charging.

It fits MacBook Air/Pro 13, iPad Pro, iPad Air and other USB-C laptops, tablets, docks and monitors that accept Thunderbolt 3, Thunderbolt 4, USB 3.2, USB 3.1 or USB 3.0. Buyers who need a longer reach than 4ft or a right-angle connector should look at something else.

40Gbps Thunderbolt 4 data rate decides fit

The single figure that determines whether this is the right part is the 40Gbps Thunderbolt 4 data rate. If the host, dock or device only supports slower USB-C speeds the extra bandwidth will not be used. The cable is backward compatible, but the full 40Gbps and 240W require matching hardware on both ends.

Questions about this item

How do I plug the USB‑C to USB‑C cable into my Thunderbolt 4 dock without bending the connector?

Align the oval USB‑C plug with the port on the dock and insert straight in; the reversible male‑to‑male design means either end works, but forcing it at an angle can damage the internal pins.

Will the 240 W charging capability degrade over time with daily use?

The cable is rated for up to 240 W at 48 V/5 A and uses passive copper conductors; normal daily charging does not reduce its power‑delivery rating, though physical wear on the connectors can eventually affect contact reliability.

At what point does sustained 40 Gbps transfer hit a thermal or length limit on this 4 ft cable?

The 4 ft length stays within the passive Thunderbolt 4 spec for 40 Gbps, so the first limit under continuous load is usually the host or device controller throttling, not the cable itself.
