One adapter for three connections

The IOGEAR GUC3C3H turns a single USB-C port into an HDMI output, a USB-C downstream port and a USB-A port. It supports video up to 3840 x 2160 at 30Hz and passes through up to 60W of USB-C Power Delivery. The white adapter measures 0.50" x 2.40" x 1.60" and weighs 0.05 lbs. It works with Thunderbolt 3 hosts using a USB-C male 24-pin connector.

Replaces a tangle of single-purpose dongles

Instead of carrying separate HDMI, USB-A and charging adapters, this one unit handles video, data and power together. The jump is worth it when a laptop or tablet has only one USB-C port but must drive an external display, connect legacy peripherals and stay charged at the same time. USB 3.1 Gen 1 provides 5Gbps on each downstream port for everyday accessories.

Fits ultra-portable setups with limited ports

Plug the adapter directly into the host USB-C port; no external power brick is required because the PD pass-through draws from the host charger. It frees up the remaining ports on a compact dock or hub by consolidating display and legacy USB-A needs into one device. The short integrated cable keeps the arrangement tidy on a small desk or in a travel bag.

Questions about this item

What USB-C port size does the GUC3C3H plug into?

The adapter uses a 24-pin USB Type-C male connector that fits any standard USB-C port on your laptop or tablet.

How do I set up the GUC3C3H so the HDMI display works?

Connect the adapter to your USB-C port, plug an HDMI cable into the HDMI output, then attach your monitor; the video link activates automatically with no driver install required.

Will the USB-C downstream port on the GUC3C3H need a firmware update later?

No firmware updates are needed; the USB-C downstream port and USB Type-A port both run at 5 Gbps and will continue working as long as the adapter is undamaged.
