USB 4.0 Cable 1.5ft 40Gbps 240W

This USB 4.0 cable uses USB-C connectors and delivers 40Gbps data transfer with 240W Power Delivery charging. It supports 8K at 60Hz or dual 4K at 60Hz video output when the host port includes DisplayPort Alternate Mode. The 1.5ft length suits desk setups linking laptops, monitors, docks and high-speed storage. Backward compatibility covers USB 3.2, 3.1 and 2.0 devices.

Who This Suits and Who Should Look Elsewhere

Buyers needing a single cable for maximum-speed data, high-wattage charging and 8K video on Thunderbolt 4 or 3 hosts will benefit. Users whose ports only support USB 2.0 or 3.0 speeds cannot use the 40Gbps bandwidth or 240W charging. Anyone requiring a longer reach for under-desk routing or across-room connections should choose a different length.

Deciding Specification: 40Gbps Data and 240W PD

The 40Gbps throughput combined with 240W Power Delivery is the defining capability. If the connected hardware negotiates only lower USB speeds or lacks PD 3.1 Extended Power Range, the cable will operate at those reduced limits. Verify that both host and peripheral support USB4 or Thunderbolt 4 to unlock the full 40Gbps and 240W performance.

Questions about this item

Does the 1.5ft USB4 cable get warm or draw extra power when running at 40Gbps all day?

The cable carries up to 240W PD 3.1 Extended Power Range, so it handles high-power charging without overheating during sustained 40Gbps data transfers.

What must my laptop port support to get 8K@60Hz video through this USB4 cable?

Your USB-C port needs DisplayPort Alternate Mode; without Alt Mode the cable cannot output video even though it supports 8K@60Hz or dual 4K@60Hz.

Will this USB4 cable work at full speed with my older Thunderbolt 3 dock and USB 3.2 devices?

Yes, it is backward compatible with Thunderbolt 3 and USB 3.2, 3.1, 2.0 speeds, so legacy docks and peripherals still function at their rated rates.
