3-in-1 USB-C Adapter for 4K Mirroring

This compact 3-in-1 adapter connects a USB-C laptop, tablet or phone to an HDMI display while adding power delivery and a USB 3.0 data port. It is built for users who need a single cable solution for screen mirroring, charging and peripheral access during presentations, streaming or editing sessions.

Aluminium Housing with Pass-Through Charging

The aluminium alloy body dissipates heat during sustained 4K@120Hz output and the integrated 100W PD 3.0 port keeps the host device powered without a separate charger. A reversible USB-C plug and a standard HDMI socket make daily connections straightforward, while the extra USB 3.0 port accepts flash drives or other 5Gbps peripherals.

HDMI Bandwidth Limits 120Hz at 4K

The HDMI link delivers 4K resolution at 120Hz, so higher refresh rates or resolutions beyond that ceiling are not supported. The USB 3.0 port is capped at 5Gbps, limiting transfer speed for the fastest external SSDs. Devices without a USB-C video-output mode cannot use the video function.
