  • 40 Gbps bandwidth moves large files quickly
  • 240 W charging powers demanding laptops fast
  • 8K 60 Hz or dual 4K 60 Hz video from one cable
  • Works with Thunderbolt 3 and 4 hosts and peripherals

One cable for USB4, Thunderbolt and 240 W charging

This USB4 cable delivers up to 40 Gbps bandwidth, 8K video and 240 W power delivery in a 3.3 ft nylon-braided USB-C to USB-C form. It supports USB PD 3.1 Extended Power Range at 28 V, 36 V and 48 V, plus backward compatibility with USB 3.2, 3.1 and 2.0 devices. Designed for users who need one lead for high-speed data, display output and maximum charging from a single port.

Who this suits and who should look elsewhere

Ideal for professionals connecting Thunderbolt 3 or 4 docks, 8K monitors and high-wattage laptops that require the full 240 W profile. Not suitable for buyers who need a longer reach than 3.3 ft, or for setups where the host USB-C port lacks DisplayPort Alternate Mode for video. Also not intended for users who only require basic 60 W or 100 W charging and have no use for 40 Gbps throughput.

The deciding specification

Maximum power delivery of 240 W under USB PD 3.1 EPR determines whether this cable matches the charger and device combination. If the power source and sink both support 48 V at 5 A, the cable enables the highest charging rate; otherwise it will negotiate a lower compatible level.

Questions about this item

Does the cable include any power adapters or do I need to buy a USB PD 3.1 charger separately for 240W charging?

The cable alone supports up to 240W via USB PD 3.1 Extended Power Range at 48V; you must supply a compatible 240W charger and a host that accepts 48V/240W.

Should I choose this 40Gbps cable or a 20Gbps USB4 cable for my setup?

Pick the 40Gbps version when your host and device both support 40Gbps USB4 or Thunderbolt 4; the cable is backward compatible with 20Gbps USB4 gear if needed.

Will I actually see 8K@60Hz on my monitor with this 3.3ft cable?

Yes, provided the source USB-C port supports DisplayPort Alt Mode and the monitor accepts 8K@60Hz; the cable carries the full 40Gbps bandwidth required for that signal.
