Dual 4K 30Hz HDMI Adapter

This MCHOSE USB-C hub adds two HDMI outputs a USB 3.0 port and 100W power delivery through a single cable. It is built for laptop users who need dual external monitors and simultaneous charging without carrying multiple dongles. The adapter requires a host port with DisplayPort Alt Mode to function.

Upgrade from single-port dongles

It replaces basic single-HDMI adapters that only drive one screen and lack pass-through charging. The jump is worth it when you regularly connect two displays at 1080p 60Hz or one display at 4K 30Hz while keeping the laptop powered. It does not suit users who need 4K 60Hz on both screens or who lack an Alt Mode capable USB-C port.

Driver-free plug and play

Installation is driver-free on Windows and macOS the hub enumerates as a standard display device the moment it is connected. The most common issue is a host port that only carries USB data and not video which yields no picture at all. Using a cable that lacks the required Alt Mode wires or exceeding the 100W PD budget of the charger can also cause unstable operation.

Questions about this item

Does the adapter need an external power supply to run two 4K monitors at 30Hz?

No, the hub draws power from the host USB-C port and passes up to 100W PD charging through to the laptop while driving both displays.

My laptop only has a standard USB-C data port — will the dual HDMI outputs still work?

The host port must support DisplayPort Alt Mode; a plain USB-C data port cannot carry the video signal required for the two HDMI outputs.

How often should I replace the USB-A 3.0 port if I use it daily for external drives?

The USB-A 3.0 port is rated for thousands of insertion cycles; under normal daily use it will not need scheduled replacement.
