What this cable does

The Jansicotek TJ-A323 is a USB4 cable built for users who need one lead that carries 40Gbps data, 100W power and 8K@60Hz video. It suits laptop owners, creative professionals and anyone docking a Thunderbolt 3 or 4 host to a monitor, drive or charger.

The spec that decides fit

This cable delivers 40Gbps throughput and 100W (20V/5A) Power Delivery 3.1 with an E-marker chip. If your workflow demands that bandwidth and wattage combination, the TJ-A323 matches it; if your device only negotiates lower speeds or power, the extra headroom will not be used.

Who should buy — and who should not

Buyers with Thunderbolt 3 or 4 ports, USB-C Alt Mode displays or high-wattage chargers get full benefit. Users whose ports lack DisplayPort Alternate Mode cannot drive 8K video, and anyone needing a longer reach than 3.3-foot should look elsewhere.

Questions about this item

What does 40Gbps mean when I plug this cable into my laptop?

The cable moves up to 40 Gbps of data between Thunderbolt 3, Thunderbolt 4 and USB4 devices, so large files and backups finish in roughly half the time of a standard USB C cable.

Which standard caps the 40Gbps and 100W ratings in daily use?

USB4 Gen 3x2 limits data to 40 Gbps while PD 3.1 and the built-in E-marker chip cap power delivery at 100 W (20 V / 5 A) when both ends support it.

Will the 3.3-foot length reach my monitor on a desk mount?

At 3.3 feet the male-to-male USB C cable spans a typical desk-to-monitor gap; the reversible connectors plug either way up without forcing the port.
