UANTIN USB C Hub 7 in 1 Multiport Adapter with 4K HDMI Dongle Review
Discover the USB C Hub 7-in-1 Multiport Adapter, a tech lifesaver for clutter-free workspaces. Streamline with 4K HDMI, 100W PD, SD/TF readers, and more!
Under two ounces. Smaller than a credit card. Seven ports including 4K HDMI, 100W PD, three USB-A, and SD/TF card readers. The UANTIN 7-in-1 is the kind of hub that disappears into a pocket and gets forgotten until you need a monitor at a coffee shop, a card reader at a photo shoot, or a USB port at an airport. At 2.75″ x 1.2″ x 0.39″ in aluminum, it is physically the smallest hub with this port combination that has crossed this desk. The compatibility list names everything from iPhone 15 to Steam Deck to ROG Ally to Samsung Galaxy tablets — that breadth is uncommon for a generic-looking 7-port hub.
4K@30Hz or 1080p@120Hz through HDMI. Three USB-A ports. SD and TF card readers. 100W PD pass-through. Plug and play on Windows, macOS, Linux, iPad OS. 2-year warranty. 1.9 ounces.

1080p at 120Hz: The Hidden Spec
Most 7-port hubs list 4K@30Hz and stop there. The UANTIN adds 1080p@120Hz compatibility. For a user who connects to a 1080p monitor and cares about smooth motion — scrolling, cursor movement, dragging windows — 120Hz feels significantly more fluid than 30Hz or even 60Hz. The hub negotiates the resolution and refresh rate based on the monitor’s capability. Connect a 4K monitor and you get 4K@30Hz. Connect a 1080p 120Hz monitor and you get 1080p@120Hz. The hub supports both modes through the same HDMI port.
This matters for gamers using the ROG Ally or Steam Deck through this hub. A 1080p TV at 120Hz running a handheld game console through this hub provides smoother gameplay than 4K@30Hz would. The spec is buried in the product description but it changes the use case for anyone with a high-refresh display.
1.9 Ounces in Aluminum
At 1.9 ounces, the UANTIN weighs less than a AA battery and a half. The aluminum body dissipates heat better than plastic, which matters for a hub running HDMI output, USB devices, and PD charging simultaneously in a body this small. Heat concentrates faster in smaller enclosures, and aluminum radiates it away where plastic would trap it. The 2.75″ x 1.2″ footprint means the hub is shorter than a thumb drive and narrower than two fingers side by side. It clips into a keychain pouch, a laptop bag pocket, or a jacket pocket without registering as extra weight.
100W PD Pass-Through
Connect your charger to the USB-C PD port and the hub passes through up to 100W to the laptop while HDMI, USB, and card readers all run simultaneously. The hub does not include a charger — you supply your own. At this size, the hub consumes minimal power itself, so the pass-through efficiency is high. A 100W charger delivers close to 100W to the laptop because the hub’s own draw is small.
Three USB-A: Speed Mix
The three USB-A ports include both USB 3.0 (5 Gbps) and USB 2.0 (480 Mbps). The exact split per port is not specified in the product data. For a flash drive or external SSD, plug into a USB 3.0 port for speed. For a mouse or keyboard, any port works. If you connect a slow device to a 3.0 port, it functions normally — it just does not need the bandwidth. If you connect a fast device to a 2.0 port, the transfer speed bottlenecks at 480 Mbps.
ROG Ally, Steam Deck, iPhone 15
The compatibility list names devices that most 7-port hubs do not mention: ASUS ROG Ally, Steam Deck, iPhone 15 series, Samsung Galaxy tablets, iPad mini 6. For handheld gaming consoles that output to a TV through a USB-C hub, the UANTIN provides 4K@30Hz or 1080p@120Hz HDMI alongside USB for controllers and PD for charging. For iPhone 15 users who want to mirror their screen to a monitor while charging and connecting USB accessories, the hub handles all three simultaneously.
Drawbacks
| Consideration | Detail |
|---|---|
| 4K@30Hz | Not 60Hz at 4K. Scrolling less smooth. |
| USB Port Speed Mix Unclear | Three USB-A ports but exact 3.0 vs 2.0 split not specified per port. |
| Single Monitor Only | One HDMI port. No dual display. |
| No Ethernet | Wired network requires a separate adapter. |
| No Audio Jack | No 3.5mm output. |
| PD Port: Charging Only | No data or video through PD port. |
Who This Hub Is For
Anyone who needs a 4K HDMI hub with card readers and 100W PD that weighs under two ounces and fits in a pocket: The UANTIN is the hub for people who forget they are carrying a hub until they need one. Aluminum at 1.9 oz. 4K@30Hz or 1080p@120Hz. SD/TF readers. 100W PD. ROG Ally, Steam Deck, and iPhone 15 compatible. 2-year warranty. If every gram in your bag matters and you need a monitor, USB, card readers, and charging from one device, the UANTIN provides that at a size and weight that adds nothing noticeable to what you carry. For a 7-in-1 with Ethernet instead of card readers, see the Hiearcool USB-C Hub review.
Users who need Ethernet, dual display, audio, or guaranteed fast USB on every port: One HDMI, no Ethernet, no audio. USB speed split unclear. For expanded connectivity, see the docking stations hub page.
Final Verdict
The UANTIN 7-in-1 does what a pocket hub should do: provide the ports you need at a weight you do not notice. 4K@30Hz and 1080p@120Hz through HDMI cover both resolution and refresh rate preferences. Three USB-A ports handle peripherals. SD/TF readers cover card transfers. 100W PD keeps the laptop charged. Aluminum dissipates heat in a body smaller than a matchbox. The 2-year warranty and broad device compatibility — including gaming handhelds, phones, and tablets alongside laptops — make it useful beyond just laptop docking. At 1.9 ounces, the question is not whether to carry it. The question is why you would leave it behind.

Docking Station Intelligence
The standards are confusing by design. These three panels decode what manufacturers won’t explain clearly. Applicable to every docking station.
The USB-C Confusion Matrix
The USB-C connector is the single greatest source of buyer confusion in docking stations. The physical plug looks identical whether it carries USB 2.0 at 480 Mbps or Thunderbolt 5 at 120 Gbps — a 250x difference in capability hidden behind the same shape. Manufacturers exploit this by labeling everything "USB-C compatible" without specifying which protocol runs through it. Two docks can look identical on the outside and behave completely differently once you plug them in.
The hierarchy matters because it determines everything: how many monitors your dock can drive, how fast files transfer, whether your laptop charges while docked, and whether you need third-party drivers. Here is the real capability ladder, from slowest to fastest:
The practical takeaway: if your laptop has Thunderbolt 4, buy a Thunderbolt dock. If it only has generic USB-C, verify whether it supports DisplayPort Alt Mode before buying anything with multi-monitor claims. Our buying guide walks through verification steps for every major laptop brand.
Power Delivery: What the Watts Mean
Power Delivery (PD) determines whether your docking station can charge your laptop while you work, or whether you need a separate charger cluttering your desk. The math is simple but rarely explained: your laptop draws a specific wattage under load, and the dock must match or exceed it. If the dock delivers less than your laptop needs, the battery slowly drains even while plugged in — defeating the purpose of a docking station entirely.
Most ultrabooks need 45–65W. Standard business laptops need 65–100W. Gaming and workstation laptops can demand 100–140W or more. The dock’s advertised PD wattage is the maximum it can deliver to your laptop — but this drops if you charge other devices (phones, tablets) through the dock simultaneously. Always leave a 15–20W margin above your laptop’s requirement.
Check your laptop’s original charger wattage — that’s your baseline. Our FAQ covers how to find this for every major brand.
Native Display vs DisplayLink: The Hidden Factor
This is the decision most buyers don’t know they’re making. When a docking station outputs video to your monitors, it uses one of two fundamentally different methods: native (the dock passes your laptop’s GPU signal directly to the monitor) or DisplayLink (the dock compresses video over USB and a software driver renders it). The difference is invisible in marketing materials but profoundly affects your daily experience.
Native output through DisplayPort Alt Mode or Thunderbolt uses your laptop’s actual graphics hardware. There is zero added latency, full DRM support for streaming services, no CPU overhead, and no driver to install. DisplayLink, by contrast, adds 5–15ms of latency (noticeable in video calls and cursor movement), blocks DRM content on connected monitors (Netflix, Disney+ show black screens), consumes 3–8% of your CPU constantly, and requires a driver that Apple’s macOS security updates occasionally break.
DisplayLink exists for one reason: Apple Silicon base chips (M1, M2, M3) can only drive one external display natively. If you need two or more monitors on a base MacBook Air or 13” MacBook Pro, DisplayLink is your only option. For everyone else — Windows users, Mac Pro/Max chip users, Intel/AMD laptops — native is always the better choice.
Native (Alt Mode / Thunderbolt)
DisplayLink (USB compression)
The bottom line: if your laptop supports native multi-display output, always choose a native dock. DisplayLink is a workaround, not an upgrade. See our glossary for detailed definitions.
