USB4 cable with 240W charging

This USB4 cable delivers up to 240W of power at 48V and 5A, enabling rapid charging for compatible laptops such as the MacBook Pro. It supports data transfer rates up to 40Gbps when both connected devices support that speed. The cable also carries video signals up to 8K at 60Hz or dual 4K displays using two cables.

Professionals needing maximum throughput

Users who require the full 40Gbps bandwidth for high-resolution displays, external GPU enclosures or fast storage will benefit from the USB4 and Thunderbolt 4 compatibility. Buyers whose devices only support lower USB standards will not see the top speeds or 240W charging.

40Gbps USB4 data rate

The decisive specification is the 40Gbps data transfer rate combined with USB4 and Thunderbolt 4 support, which determines whether the cable can drive 8K video and deliver 240W charging for your setup.

Questions about this item

What does the USB4 40 Gbps rating actually limit in daily use?

The cable can move up to 40 Gbps when both host and device support that speed; otherwise it falls back to the highest rate the endpoints allow.

What physical clearance does the USB-C to USB-C 4 ft cable need for routing?

It has standard USB-C plugs on each end and a 4 ft length, so plan for the connector depth plus the cable bend radius behind the device.

How do you connect the cable to enable 240 W charging on a MacBook Pro?

Plug one end into a 240 W capable USB-C power adapter and the other into the MacBook Pro; the cable negotiates 48 V / 5 A automatically.
