Cable overview

The Jansicotek TJ-A323 is a 6.6 ft USB4 cable built for users who need one lead to handle high-speed data, 8K video and up to 100 W charging. It connects USB-C devices such as laptops, phones and external GPUs with a single reversible plug.

Thermals and power

The integrated E-marker chip identifies the cable as 5 A capable and negotiates PD 3.1, PD 3.0 PPS, PD 2.0, QC 4.0, QC 3.0, AFC, SCP and FCP profiles so the attached charger delivers only the current the device requests. No active cooling is required and the cable runs silently during sustained 100 W loads.

Deciding specification

The cable is certified for 40 Gbps USB4 Gen 3×2 bandwidth, enabling a single 8K display at 60 Hz or dual 4K at 60 Hz; if your workflow only needs 20 Gbps Gen 2 speeds or lower video resolutions, a less expensive cable will suffice.

Questions about this item

How do I install this 6.6 ft USB4 cable and what step do people often miss?

Connect the USB C male plugs to both devices; the reversible design prevents upside-down insertion. The step users miss is confirming the host port supports USB4 Gen 3x2 or Thunderbolt 4 to unlock 40Gbps bandwidth and 100W PD 3.1 charging.

What maintenance or replacement will this cable need later?

No scheduled maintenance is required. Replace the cable if the connectors become loose, the jacket shows cuts, or the E-marker chip fails to negotiate 20V/5A power delivery with a compatible charger.

What limit appears first during sustained 40Gbps transfers or 100W charging?

The 6.6 ft length and copper construction mean heat buildup in the cable and host ports becomes the first bottleneck, potentially causing the link to drop from Gen 3x2 to Gen 2x2 speeds under continuous heavy load.
