What the cable is and who it fits

The Jansicotek TJ-A323 is a USB4 Gen 3x2 cable with USB-C male connectors on both ends. It carries data at up to 40Gbps, delivers up to 100W of power at 20V/5A and drives an 8K display at 60Hz over a 6.6 ft braided run. An integrated E-marker chip identifies the 5A capability so the charger negotiates the correct current automatically. It works with Thunderbolt 4 and Thunderbolt 3 hosts and is backwards compatible with USB 3.2, USB 3.1 and USB 3.0 devices.

Who benefits and who should look elsewhere

Creative professionals who need a single cable for 8K video output, 40Gbps data transfer and 100W laptop charging will find it fits the brief. Users who only require 4K@60Hz video, 10Gbps data or 60W charging can use a shorter, less expensive USB 3.2 or Thunderbolt 3 cable instead. Buyers needing a cable longer than 6.6 ft or a right-angle connector for tight ports should consider other form factors. Anyone with legacy USB-A or micro-USB ports cannot use this cable without an adapter.

Capacity and headroom

The 40Gbps bandwidth handles uncompressed 8K@60Hz video (3840x2160) and dual 4K streams when two cables are used, leaving headroom for high-speed SSD traffic. The 100W PD 3.1 supply charges a MacBook Pro to full capacity in roughly 1.5 hours and powers most ultraportables at their maximum rate. Data throughput drops to the host controller limit when connected to USB 3.2, 3.1 or 3.0 ports, so the 40Gbps ceiling is only reached with Thunderbolt 4 or USB4 Gen 3x2 endpoints.

Questions about this item

Does this cable need a USB-C charger to deliver 100W?

Yes, it requires a PD 3.1 or compatible charger that can supply 20V/5A.

Will the 40Gbps speed work with my Thunderbolt 3 dock?

It is backwards compatible with Thunderbolt 3, but the dock must also support 40Gbps to reach that rate.

How can I confirm 8K@60Hz video is active?

Check your display settings show 3840x2160 at 60Hz while the cable is connected.
