Cable identity and audience

The Jansicotek TJ-A323 is a 1.6FT USB4 Gen 3x2 cable with USB C male connectors on both ends. It delivers 40 Gbps data transfer, 100W Power Delivery 3.1 charging and 8K@60Hz video in a single black cable. The bi-directional, reversible design targets professionals who connect Thunderbolt 3 or 4 docks, eGPU enclosures, NVMe SSD enclosures and high-resolution monitors to laptops such as MacBook Pro 16 or iPhone 15.

What the integrated E-marker changes

A built-in E-marker chip identifies the cable as 5A capable so the host can negotiate PD 3.1 Extended Power Range at 20V/5A safely. This enables 30-minute charging of a MacBook Pro 16 from 0 to 60 percent battery while simultaneously driving one 8K@60Hz display or dual 4K@60Hz displays without separate power bricks or signal degradation.

Suitable users and limits

The 1.6FT length suits desktop setups where the host and peripheral sit side by side. Buyers needing longer reach for conference-room displays or under-desk routing should look at something else. The cable also does not serve devices that require legacy USB-A or proprietary connectors, nor situations where a captive cable on the peripheral prevents a male-to-male connection.

Questions about this item

Does the 1.6 ft USB4 cable require any periodic connector cleaning or E-marker chip maintenance to keep its 40 Gbps rating?

No scheduled cleaning or chip maintenance is needed; the built-in E-marker simply identifies 5 A capability and the reversible USB-C plugs stay reliable with normal handling.

What is the first limit reached when the cable runs at 40 Gbps continuously — thermal throttling or the 100 W power ceiling?

The 100 W (20 V / 5 A) power delivery ceiling is the fixed limit; the cable carries 40 Gbps without a separate thermal throttle point.

How warm does the cable get and does it make any noise when delivering 100 W and 40 Gbps all day?

The cable remains passive and silent; any warmth stays within normal USB-C operating range during sustained 100 W charging and 40 Gbps transfers.
