A USB-C cable delivering 40Gbps data transfer, 240W charging and 8K video output

Cable Length 3.3 Feet

  • 240W PD 3.1 fast charging powers laptops in 35 minutes
  • 40Gbps USB4 data rate moves 2.5G files per second
  • 8K@60Hz or dual 4K@60Hz video over Thunderbolt 4

  • 3ft nylon-braided cable works with Thunderbolt 3, USB 3.2, 3.1, 3.0

USB4 Gen3 cable with 40Gbps bandwidth

This USB4 Gen3 cable delivers up to 40Gbps data transfer and 240W power delivery. It supports 8K video at 60Hz and 4K at 144Hz for compatible displays. The 3.3ft length suits desktop and mobile connections.

Plug-and-play with E-Marker protection

The cable works immediately with any USB-C port and requires no drivers or software. An integrated E-Marker chip regulates voltage and current to protect connected devices. Improper performance usually comes from host ports that lack Alt Mode or 40Gbps support.

Limited by host port capabilities

Maximum 40Gbps speed and 240W charging only occur when both ends support USB4 Gen3 and PD 3.1. Video output needs DisplayPort Alt Mode on the source device. Older USB 3.2 or Thunderbolt 3 ports reduce bandwidth and power to their own limits.

Questions about this item

How can I verify the cable is delivering 40Gbps after connecting it?

The box contains the 3.3ft USB-C to USB-C cable with E-Marker chip; you need a 240W-capable charger and devices that support USB4 or Thunderbolt 4 for full performance.

Which version should I choose for 8K@60Hz video and 240W charging?

This single USB4 Gen 3 cable handles both 8K@60Hz video output and up to 240W PD 3.1 charging; no other version is offered.
