For a USB-C laptop that needs connections for a display, data devices, and card media, the Hiearcool UCN3286 brings key ports together in one compact hub. Its 4K HDMI output, USB 3.0 data transfer, and SD/TF card readers support a flexible desk or travel setup. Need to connect a monitor and access files from a memory card in the same workspace? The hub combines those tasks with pass-through power delivery in a plug-and-play design.

Tech summary

This 7-in-1 hub has an HDMI interface, USB 3.0, USB-C power delivery, and SD and TF card readers. HDMI supports output up to 4K at 30Hz, useful for viewing work on a larger screen or connecting to a projector for a presentation. USB 3.0 transfers data at up to 5Gbps, while the card slots provide direct access to photos, video, and other files stored on SD or TF cards.

USB-C PD pass-through supports charging up to 100W while you use the hub. The enclosure is aluminum, and the space gray finish pairs neatly with a laptop setup. It measures 4.17 x 1.4 x 0.34 inches and weighs 1.8 ounces, making it easy to carry between a desk, classroom, meeting room, or travel bag. The hub is listed for compatible USB-C devices including MacBook, iPad, Dell, HP, and Lenovo models, along with Steam Deck and USB-C smartphones.

Buyer feedback often highlights the hub’s useful mix of ports, compact size, and straightforward plug-and-play use, including with MacBook Pro models. Connectivity experiences are mixed: some customers report stable connections, while others describe intermittent connection issues. This feedback can help set expectations when choosing a multiport hub for a regular setup.

Best use cases

At a desk, connect an HDMI monitor while keeping USB devices and card media accessible through one hub. For a meeting or class, HDMI output offers a way to connect a compatible laptop to a display or projector. Photographers and other creators can use the SD and TF readers to access files directly, while USB 3.0 supports transfers at up to 5Gbps.

Compared with carrying separate adapters for a screen, USB connections, and card slots, this all-in-one layout brings those functions together in a single accessory. It suits you if you want a compact hub for a compatible USB-C device and value having display, data, card-reader, and pass-through charging connections in one place.

Usage tips

Connect the hub to a compatible device’s USB-C port, then use the relevant port for your display, USB device, or SD/TF card. For an external screen, match your setup to the hub’s HDMI output, which supports up to 4K at 30Hz. To use pass-through charging, connect a USB-C power source to the hub’s PD connection, supported delivery is up to 100W. Plug-and-play operation keeps setup simple for everyday work, presentations, and travel.

Is it worth it?

The Hiearcool UCN3286 is a practical fit for people who regularly move between a laptop and external displays, USB devices, or memory cards. Its combination of 4K@30Hz HDMI, up to 5Gbps USB 3.0, SD/TF readers, and up to 100W power delivery makes it particularly useful when you want a single compact accessory for both desk work and on-the-go setups.
