Portable 67W dock with 4K HDMI

The Mirabox CD0303-6-B-67-BL combines a USB-C dock and a foldable-plug AC charger in one black unit. It delivers up to 67W of USB-C Power Delivery and a 4K 60Hz HDMI output for external displays. A full-featured USB-C to USB-C cable is included in the box.

Foldable plug and bundled cable

The US foldable plug lets the device function as both a wall charger and a docking station without a separate power brick. The included full-featured USB-C to USB-C cable carries video, data and charging current in a single connection. GaN circuitry provides overcurrent, overheating and overvoltage protection during operation.

Check host port and power needs

Verify that your device has a USB-C port with DisplayPort Alternate Mode and Power Delivery support to enable both video output and charging. The dock supplies up to 62W to the host, so confirm that this meets your device's charging requirement. HDMI 4K 60Hz output requires a compatible display and cable capable of that resolution and refresh rate.

Questions about this item

Will the USB-C cable need replacing after heavy daily use?

The included full-featured USB-C to USB-C cable is built for repeated docking cycles; no user-serviceable parts inside the dock itself require periodic replacement.

What limits 4K 60 Hz output during long gaming sessions?

The HDMI port is rated for 4K at 60 Hz; sustained output at that resolution depends on the host device maintaining a stable DisplayPort Alt Mode signal and adequate thermal headroom.

How hot does the GaN charger get when running at 67 W all day?

The GaN chipset includes over-temperature protection that throttles power if the enclosure exceeds safe limits, keeping surface temperatures within normal operating range for a 67 W adapter.
