Compact USB4 U-Type Adapter

This U-shaped USB-C male-to-male adapter carries USB4 performance in a low-profile form factor. It delivers 240W power, 40Gbps data throughput and 8K video at 60Hz for docking stations, external SSDs and high-resolution displays. The short, space-saving design fits tight ports on laptops, handhelds and tablets without blocking adjacent sockets.

Suits USB4 and Thunderbolt 4/3 hosts

Gamers using a ROG Ally or Steam Deck, professionals docking a Mac or iPhone 16/15 Pro Max, and anyone connecting a Switch to a monitor gain full USB4 bandwidth and charging in one dongle. Users whose devices only support USB 3.2 or earlier will not reach the adapter's peak data or video rates and should consider a cable matched to their port's native specification.

40Gbps USB4 bandwidth

The single specification that decides fit is the 40Gbps USB4 data rate combined with 240W power delivery and 8K@60Hz video. If the host port is limited to lower USB generations, the adapter will function but cannot exceed the host's own ceiling, so buyers needing maximum throughput must confirm their device advertises USB4 or Thunderbolt 4/3 support.

Questions about this item

What USB-C devices must I already own for this male-to-male adapter to work?

Will this adapter work with my older Thunderbolt 3 dock and laptop?

Yes, it is compatible with Thunderbolt 3 and 4, so it will pass 40Gbps data, 8K@60Hz video and 240W power through your existing Thunderbolt 3 dock.
