Dual HDMI Adapter with Power Delivery

This USB-C adapter connects a single USB-C or Thunderbolt 3 port to two HDMI displays, a 3.5 mm audio jack and a 100 W USB-C charging pass-through. It is built for professionals who need a compact dock to drive dual external monitors while keeping a laptop powered from its original charger.

Mac OS Mirror-Only Limitation

On macOS the adapter can only mirror the same image to both HDMI outputs because the operating system does not support Multi-Stream Transport over a single USB-C link. Windows systems support both mirror and extended desktop modes, so buyers who need independent screens on a Mac should look elsewhere.

Resolution Range and Charging Headroom

The adapter handles resolutions from 640×480 at 60 Hz up to 3840×2160 at 60 Hz on each HDMI port, covering common office and 4K workflows. The 100 W charging pass-through supplies ample power for most ultraportables, though laptops that draw more than 100 W under load will not charge at full speed.

Questions about this item

Does the 4K @ 60 Hz rating apply to each monitor when both HDMI ports are used?

Yes, the adapter can drive two displays at up to 3840x2160@60Hz simultaneously on Windows systems.

What does the 100 W Power Delivery port actually supply to the laptop?

It passes through up to 100 W from your original charger, so the laptop charges at full speed while the adapter runs both screens and audio.

How much clearance is needed behind the USB-C port for the adapter body?

The compact dongle sits flush against the port and adds only a few centimetres of depth, fitting alongside other cables on MacBook Pro, Dell XPS 13 or 15, and similar laptops.
