USB-C extension with Thunderbolt 3 support

This six-foot male-to-female cable adds reach between a host and any USB-C or Thunderbolt 3 peripheral. It carries data at USB 3.2 Gen 1 speeds up to 5 Gbps and delivers up to 60 W of Power Delivery charging at 20 V 3 A. Nickel-plated connectors and a VW-1 rated PVC jacket provide durable everyday connectivity.

Suitable for laptop users needing extra cable length

The cable suits anyone extending a dock, charger or smartphone connection without losing data throughput or charging capability. It is not for setups that require longer runs than six feet, higher wattage than 60 W, or data rates beyond 5 Gbps. Buyers needing Thunderbolt 4 certification or active signal boosting should look elsewhere.

Simple plug-and-play installation

No drivers or software are required; connect the male end to the host and the female end to the device. The only common issue is attempting to exceed the 60 W power limit or 5 Gbps bandwidth, which will fall back to lower performance. Ensure both ports support the desired features before relying on full speed or charging.

Questions about this item

Does my charger need to supply 20V at 3A for the cable to deliver 60W?

Yes, the cable passes up to 20V 3A (60W) so the charger must provide that profile for full power.

Will a USB 2.0 peripheral still work when connected through this 5 Gbps extension?

Yes, the cable is backward compatible with USB 2.0 devices and will operate at their native speed.

How can I confirm the link is running at 5 Gbps after plugging it in?

Check the OS connection speed or run a file transfer; a sustained rate near 5 Gbps shows the Gen 1 link is active.
