Our take
UtechSmart identifies UCN3317-3 as a MacBook-oriented seven-in-two hub with three USB-A ports, HDMI, Thunderbolt 3 and SD/TF readers. The maker links the historical ASIN to this model, but the current Amazon detail page was unreadable.
A buyer with a supported MacBook generation, side-by-side USB-C ports and a case-free connection area who wants a compact attached hub..
A computer outside the maker's named MacBook ranges, a laptop case that blocks side-by-side ports, or a user requiring confirmed dual external displays on the named 2020 M1 models.
Pros & cons
What could work for you, and what to consider before buying.

What to weigh up
- Case clearance is a concern
- HDMI is listed at 4K/30Hz
- dual display has a named M1 exception
- current Amazon detail and measured performance were unavailable.

Full review: how the features affect your choice
What the features mean for you
Choose it for a MacBook that needs wired peripherals, cards and a display
This hub bundles three USB-A data connections with HDMI, a Thunderbolt 3 port and two card slots. That combination can replace a handful of separate adapters for a compatible MacBook user who moves photos, connects USB accessories and sometimes adds an external screen. Its “seven-in-two” count includes different kinds of connections: the HDMI and card slots are not additional USB data sockets. Check the side-by-side MacBook port spacing before purchase, and account for the manufacturer's warning that a fitted laptop case can obstruct it.
Check display behavior against the exact MacBook generation
The listed HDMI output reaches up to 4K/30Hz. UtechSmart says the TB3 and HDMI outputs can be used together, but excludes its named 2020 M1 MacBook Pro and Air models from dual-display use. That is a meaningful limitation if the goal is two extended monitors. Confirm the computer's host-display support and the hub's current connection diagram before relying on a specific monitor count or refresh rate.
Separate the Thunderbolt connection from the ordinary USB ports
UtechSmart lists up to 40Gbps and up to 100W charging for its TB3 port, while the three USB 3.0 ports are listed at up to 5Gbps. These are different port roles and ceilings; the hub should not be described as having four 40Gbps USB data ports. The source does not give an independently measured throughput or clarify every simultaneous-load condition, so treat the values as manufacturer limits rather than expected real-world speeds.
Use the card slots as a paired reader when that matches the workflow
The page says SD and TF can be read at the same time and lists up to 104MB/s. That makes the hub useful for a camera user who wants both formats available without another reader. The speed is not a promise that every card reaches that rate, and the source does not identify a card protocol beyond its stated maximum and capacity. Check the exact media card and MacBook setup before depending on a fast ingest workflow.
Check the suffix and the physical side-port spacing together
The resolved product name includes the maker's UCN3317-3 suffix; the frozen clue omits that suffix. Confirm the complete model number in the offer before relying on the saved port map. The hub attaches directly to the MacBook's side ports, so compare the two-plug layout with the exact computer generation and inspect whether a protective case covers either port. UtechSmart names MacBook Pro models from 2016 through 2021 and MacBook Air models from 2018 through 2021, but also warns that cases can prevent a proper fit. A model name alone therefore does not settle clearance on a particular laptop. The same compatibility check should include the display plan: the maker lists HDMI up to 4K/30Hz, describes a Thunderbolt 3 connection, and excludes its named 2020 M1 Pro and Air models from simultaneous HDMI/TB3 display use. If your routine depends on two extended screens, verify the exact computer and the current port diagram before treating the product-page description as applicable. A direct-attach hub is less flexible than a cable hub if you switch between computers, and the maker's named year ranges should not be stretched to a later model without confirmation. Buyers can compare the laptop's side view with the product diagram, including spacing between the two USB-C ports and any case lip, before they evaluate the HDMI and card features. This is a model-fit check, not a claim that the hub was tested on every MacBook in the listed range.
