USB4 Cable 3.3 ft 240W 40Gbps

This USB-C to USB-C cable delivers up to 240W of power and 40Gbps data transfer. It supports 8K video at 60Hz and works with Thunderbolt 3 and 4 devices. The 3.3 ft length suits desk and dock connections.

For high-power laptops and fast external storage

Ideal for users charging a MacBook Pro at full speed or moving large files between Thunderbolt 4 drives and docks. Buyers whose devices only support USB 3.2 or USB 3.1 will not reach the rated 40Gbps. Devices without USB-C ports cannot use this cable.

240W power delivery decides the fit

The cable handles up to 48V at 5A, matching the highest USB Power Delivery level. If your laptop or dock requires less power, the cable will still work but the extra headroom is unused. Confirm your hardware accepts 240W before buying.

Questions about this item

Does the cable get warm when delivering 240 W continuously?

The cable is rated for 48 V / 5 A, the maximum USB4 power profile, so it handles sustained 240 W charging without overheating.

What must my laptop or dock provide to reach 40 Gbps and 8K@60 Hz?

Both the host and the peripheral must support USB4 or Thunderbolt 4 with 40 Gbps signalling and DisplayPort Alt Mode for 8K at 60 Hz.

Will this 3.3 ft cable work with my older Thunderbolt 3 dock and USB 3.2 SSD?

Yes, the cable is backward compatible with Thunderbolt 3, USB 3.2, USB 3.1 and USB 3.0 devices, though speed and video capability fall back to the older standard.
