ESTONE PQ001 USB4 cable 1.5FT copper 40Gbps 240W 8K@60Hz

Purpose and audience

The ESTONE PQ001 is a USB4 Gen 3x2 cable that delivers 40 Gbps data transfer, 240 W Power Delivery 3.1 charging and 8K@60 Hz video over a 1.5 ft copper link. It suits professionals moving large NVMe datasets between enclosures, creators driving one 8K or dual 4K monitors and power users who need maximum charging speed for compatible laptops and tablets.

Compatibility checks

Verify that each USB-C port supports USB4, Thunderbolt 3 or Thunderbolt 4 and DP Alt Mode for video; the cable will fall back to lower speeds if the host or device lacks Gen 3x2 capability. Confirm the charger and device both implement PD 3.1 EPR at 48 V/5 A to reach 240 W, otherwise charging will negotiate at 140 W, 100 W or lower. Ensure any dock, hub or eGPU enclosure is rated for 40 Gbps throughput to avoid bottlenecks.

Sustained-load behaviour

The integrated E-Marker chip continuously negotiates voltage and current, keeping thermals stable during prolonged 240 W charging sessions and preventing voltage overshoot. During extended 40 Gbps transfers the cable maintains full bandwidth without throttling, so large NVMe backups or eGPU workloads complete at rated speed. Video streams at 8K@60 Hz or dual 4K@60 Hz remain artefact-free over long editing or gaming periods because the Gen 3x2 link reserves sufficient bandwidth for display traffic alongside data.
