USB-C Coupler for Cable Extension

This blue USB-C female-to-female adapter joins two shorter USB-C cables to extend reach for charging, data transfer or video pass-through. It suits users who need a longer run between a host and a peripheral without replacing the existing cables. The coupler works with USB-C equipped tablets, laptops and phones listed in the compatibility specifications.

Limits of the USB4 Interface

The adapter conforms to the USB4 specification and supports up to 40 Gbps data transfer, though actual speed depends on the connected devices and cables. Video output reaches 8K at 60 Hz when a USB4 cable is used. Power delivery handles a maximum of 240 W across the 5 V/3 A to 20 V/5 A range, so the link will not exceed those electrical limits.

240 W Power Delivery Decides Suitability

The single specification that determines whether this coupler fits the build is its 240 W power delivery ceiling. If the application demands more than 20 V at 5 A, this adapter cannot supply it. Buyers who need higher wattage for larger workstations or multi-device charging stations should look elsewhere.

Questions about this item

Should I buy the single adapter or the two-pack?

The listing is for a single blue adapter; a two-pack is a separate listing.

Will the 240 W rating actually charge my MacBook at full speed?

It passes up to 20 V at 5 A, so any USB-C device that negotiates 240 W will charge at its maximum rate.

Does the 40 Gbps figure mean I get that speed with any cable?

The coupler is USB4-rated for 40 Gbps, but the link only reaches that speed if both cables and the host also support USB4.
