What this adapter does and who needs it

The Corn Electronics three-in-one adapter adds an HDMI video output, a USB 3.0 data port and a USB-C power-delivery charging port to a single USB-C connection. It is intended for users whose laptops or tablets have a USB-C port with DisplayPort Alternate Mode and who want to mirror or extend to an external display while keeping a USB peripheral connected and the host device charged. Buyers whose USB-C ports lack video alternate mode cannot use the HDMI function.

Thermals, noise and power draw

The adapter has no fan and no moving parts, so it runs silently. Aluminium alloy and ABS construction helps dissipate the heat generated by the 100 W power-delivery pass-through and the 5 Gbps USB 3.0 traffic. Power draw depends entirely on the attached display, peripherals and the host charger; the unit itself adds no active cooling noise.

Build quality and daily connector use

The housing combines aluminium alloy with ABS plastic and measures 5.9×2.3×0.47 inch with a 3.7 inch integrated cable. Connectors are a USB-C male plug on the host side and HDMI female, USB 3.0 female and USB-C female (charging only) on the accessory side. All three ports operate simultaneously, letting you keep a monitor, a USB drive or keyboard and a charger plugged in at once. EMI protection is included to reduce interference with nearby devices.

Questions about this item

How do I install this adapter and what is the step people often miss?

Plug the USB-C male connector into a port that supports DisplayPort Alternate Mode; the adapter will not output video if the port is data-only.

What maintenance or replacement will this adapter need later?

No scheduled maintenance is required; if the ABS housing cracks or the USB-C cable frays after extended use, replace the whole unit.

What limit appears first during sustained use of this adapter?

The HDMI output is capped at 4K 30 Hz, so higher refresh rates are not possible regardless of the display or host capability.
