5 ft USB4 Cable with 240 W Power

This 1.6 m USB4 cable delivers up to 240 W of power at 48 V and 5 A when paired with a compatible charger. It supports 40 Gbps data transfer and 8K video at 60 Hz or dual 4K at 60 Hz. The cable suits users who need a single connection for charging, high-speed data and high-resolution displays.

Charging, Data and Video in One Cable

The 240 W rating means the cable can power phones, accessories and gaming laptops without a separate adapter. At 40 Gbps it can move 14 hours of HD video or 25000 HD photos in about one minute. An 8K@60 Hz or dual 4K@60 Hz signal passes through the same wire, reducing desk clutter for monitor and dock setups.

Limits of the USB4 Interface

Actual data speed depends on the host port; Gen2 ports cap bandwidth at 20 Gbps while Gen3 ports reach the full 40 Gbps. The cable does not increase the speed of a slower port or add features the host does not support. Buyers who need longer runs or active signal boosting should check the cable length against their layout.

Questions about this item

Will the 240 W charging capability require a different cable later if power standards increase?

The cable already supports the maximum 240 W (48 V/5 A) defined by the current USB Power Delivery specification, so no higher-rated cable is expected for the foreseeable future.

What limits the 40 Gbps data rate during long transfers?

Sustained throughput drops to 20 Gbps when connected to a Gen 2 port; only a Gen 3 port maintains the full 40 Gbps rate.

Does the cable get warm or draw extra power when driving an 8K display all day?

The cable is passive and carries up to 240 W for attached devices, but its own heat and power draw remain negligible during continuous 8K@60 Hz video use.
