USB4 Thunderbolt 4 Cable for Professionals

The ESTONE TJ-A323 is a USB4 Gen 3x2 cable built for creators and engineers who need full 40Gbps bandwidth, 100W power delivery and 8K video over a single link. It suits anyone connecting high-performance docks, eGPUs or 8K displays to a USB4 or Thunderbolt 3/4 port.

Male-to-Male USB-C Build with Bi-directional Use

The reversible USB-C male connectors plug either way and carry data, video and power simultaneously. Backward compatibility with Thunderbolt 3 and USB 3.2 means existing hubs, drives and monitors work without adapters, while PD 3.1, PPS and QC 4.0 support lets the cable negotiate the fastest charge a host allows.

40Gbps Throughput with 100W Charging Headroom

Rated for 40Gbps, the cable can move 14 hours of HD video or 25,000 photos in roughly one minute when both ends support Gen 3. It delivers up to 100W (20V/5A) for laptops and peripherals, and the 3.3 ft length keeps voltage drop low during sustained loads.
