Hiearcool UCN3286 7-in-1 USB-C Hub, 4K HDMI, 100W PD, Navy Blue

For a USB-C laptop setup that needs a monitor connection, everyday peripherals, and card readers in one compact adapter, the Hiearcool UCN3286 brings those connections together in a single hub.

Its HDMI output supports up to 4K at 30Hz, while two USB-A ports handle accessories such as a keyboard or flash drive. SD and microSD slots make it convenient to access files from compatible cards.

The slim aluminum body weighs 1.8 ounces, making it easy to carry between a home workspace, office, and travel bag. Plug-and-play operation means no driver installation is required.

Tips for day-to-day use

Connect the hub to a USB-C port on your laptop or other compatible device, then use HDMI to mirror or extend your screen to a monitor, TV, or projector. For video output, the host USB-C port must support DisplayPort Alt Mode, phone and tablet support for video out varies by device. The HDMI connection supports 3840 × 2160 at 30Hz or 1080p at 60Hz, giving you options for a presentation display or a standard Full HD screen.

For a desk setup, the USB-A ports can connect items such as a keyboard, flash drive, or SSD enclosure at data transfer speeds up to 5Gbps. Each USB-A port supports up to 5V/0.9A. Insert an SD or microSD card to access files without relying on a separate card reader. When you want to keep a compatible laptop powered while using the hub, connect a USB-C power source to its PD pass-through port. It supports up to 100W input, power delivered to the laptop depends on hub consumption as well as the charger, cable, and device.

Where it shines

This hub suits mobile work and study setups where a single USB-C connection needs to serve several roles. For example, connect an external display for a larger workspace, use a USB-A keyboard, and transfer files from a camera card—all with one adapter. Its aluminum enclosure and compact 4.17 × 1.4 × 0.34-inch size help keep that setup portable.

Compared with a single-purpose HDMI adapter, the UCN3286 adds USB-A connections, SD and microSD readers, and USB-C power pass-through. That makes it a useful fit when you want display output and common accessories together, rather than carrying a separate adapter for each task. Buyers often highlight its compact form, straightforward setup, and range of ports, feedback on connection stability is mixed.
