Target devices and charging performance

This USB‑C to USB‑C cable supports up to 240 W power delivery at 48 V/5 A, making it suitable for phones, accessories and gaming laptops that accept high‑wattage charging. It also carries Thunderbolt 3 and Thunderbolt 4 signals for docks and eGPU enclosures.

Video and data capabilities

The 40 Gbps bandwidth enables a single 8K display at 60 Hz or dual 4K displays at 60 Hz when two cables are used. Data transfers reach up to 40 Gbps (Gen3) or 20 Gbps (Gen2), with real‑world read speeds of 2.8 GB/s and write speeds of 2.1 GB/s.

Deciding specification

The 40 Gbps Thunderbolt‑compatible bandwidth is the single figure that determines whether this cable can drive an 8K monitor, dual 4K outputs or a high‑speed eGPU; if your workflow needs less bandwidth a slower cable would suffice.

Questions about this item

Will the USB-C male connectors on this 5ft cable fit my Thunderbolt 3 port?

Yes, the male-to-male USB-C connectors are Thunderbolt 3 compatible and fit any standard USB-C port.

Do I need drivers or a specific orientation to get 40Gbps data speeds?

No drivers are required; it is plug-and-play, but the host port must support USB4 Gen3 to reach 40Gbps — Gen2 ports top out at 20Gbps.

How do I maintain the 240W charging capability over time?

Keep the connectors clean and fully seated; the cable is rated for 48V/5A, so avoid sharp bends that could damage the internal power cores.
