USB4 Type-C extension cable 240W 3m

This three-metre USB4 cable extends a Type-C connection while supporting up to 240 W power delivery at 48 V and 5 A. It handles 8K 60 Hz video output and 40 Gbps data transfer, making it suitable for docking stations, high-resolution monitors and fast-charging laptops. The plug-and-play design works with any device that has a USB-C port.

Capacity and headroom

The cable delivers a theoretical 5000 MB/s bandwidth and real-world reads up to 2.8 GB/s and writes up to 2.1 GB/s when both host and device support the full specification. It can drive a single 8K display or two 4K displays using separate cables, and it charges phones, accessories and gaming laptops alike. Length beyond the 1.2 m USB4 standard may reduce peak signalling performance.

Upgrade path

Users replacing shorter passive cables gain the reach needed for desk-mounted docks or wall-mounted screens without losing 40 Gbps throughput or 240 W charging. The jump is worthwhile when the existing cable limits monitor placement or cannot supply enough power for larger laptops. Buyers who need longer runs without active signal boosting should note the standard length constraint.

Highlights

Questions about this item

Will the 3 m length still deliver 240 W charging to my older USB-C laptop?

The cable supports up to 240 W at 48 V/5 A, but the USB4 standard length is 1.2 m; exceeding that can reduce performance, so actual charging speed depends on your laptop's power negotiation.

How can I verify the 40 Gbps link is active after connecting the cable?

Check the host's Thunderbolt or USB4 settings for a 40 Gbps link width, or run a large file transfer and confirm read speeds approaching 2.8 GB/s and write speeds near 2.1 GB/s.

Does the package include any adapters for legacy USB-A ports?

The box contains only the 3 m USB-C to USB-C extension cable; any USB-A adapters or additional cables for dual-monitor setups must be purchased separately.
