Our take
Choose UC-109 when the needed feature is four documented USB 3.0 data ports from a USB-C host, and the attached devices fit an unconfirmed power budget. Its narrower data-hub role is useful, but the exact current offer and shared throughput still need checking.
A USB-C computer user adding four USB peripherals when the current offer visibly matches UC-109 and the devices do not require an undocumented power budget..
It is not a substitute for an HDMI, Ethernet or card-reader dock, a phone charger, or a powered hub for several high-draw devices unless current documentation supplies those missing details.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- A product-specific record identifies BYEASY UC-109 and four downstream USB 3.0 ports.
- A second reseller associates the same model and ASIN with a 5Gbps interface claim.
- The saved record keeps a separate ambiguous BYEASY listing from being merged into this model.
What to weigh up
- The host-side USB-C plug should be checked on the current offer and no broad host matrix is available.
- Power input, per-port current, cable length and aggregate bandwidth are unknown.
- The historical ASIN association does not verify that a current Amazon offer has the same configuration.

Full review: how the features affect your choice
What the features mean for you
A compact four-port hub with a confirmed UC-109 code
The UC-109 is a BYEASY USB-C hub that adds four downstream USB 3.0 ports. The model/ASIN crosswalk for B07GGMYDCW is more specific than a generic four-port hub title: the product record names UC-109, BYEASY and the exact historical ASIN together. That lets the buyer compare the code on a current offer with the reviewed model. It does not make the frozen ASIN a live or available Amazon offer, so use the tagged search and confirm the actual product label and connector layout.
Four ports expand a USB-C host, but share the host link
The listing describes one USB-C connection on the host side and four USB 3.0 downstream ports. A reseller claims transfer up to 5Gbps, which is the interface-level maximum stated for the product, not a measurement of each port while several devices are active. The sources do not give a total bandwidth budget or controller details. For a keyboard, mouse, flash drive and occasional storage use, the port expansion may be practical; for several simultaneous fast drives, ask for an aggregate throughput specification before relying on the headline speed.
Power behavior is not documented well enough to assume charging
The exact UC-109 records do not establish an external supply, dedicated charging output or per-port current. Do not infer that four available ports can safely power four high-draw devices, and do not treat the hub as a phone charger. If you plan to attach bus-powered hard drives or accessories with specific current demands, get a current manual or product page that documents the power budget. The previous BYEASY candidate packet concerns a different unresolved listing/model conflict; its power uncertainty is not silently converted into a definitive UC-109 specification.
Verify the host plug and your device mix
The indexed exact-model record identifies a USB-C hub and names compatibility with computers and some peripherals, but it does not give a model-by-model host matrix. Confirm that the current offer's upstream connector matches the laptop or tablet and that the operating system supports the intended devices. A USB-C connector does not by itself add video output or Ethernet, neither of which appears in the UC-109 port list. This is a simple data hub profile, not a multiport video dock.
Keep the older ambiguous BYEASY listing separate
Another saved BYEASY historical record, B0BNN8ZNKX, had a candidate model clue UH-109AN and a reseller package field naming UC-109. No source tied that older ASIN to either code, so it remains a distinct listing-specific profile. B07GGMYDCW has its own exact UC-109 crosswalk, but the two Amazon ASINs are not merged. Check the model number printed on any offer and use the exact-model search. This review does not assert personal testing, buyer-review consensus or current stock and pricing.
Keep the four ports in their documented role
The UC-109 evidence supports a USB-C host and four USB 3.0 data ports. It does not support adding a monitor, wired network or memory-card reader to the shopping plan, and the sources do not show a separate PD input or a current budget. That gives the product a narrower role than a multiport dock: it is a candidate for adding USB peripherals when the host's own video and network connections already meet the need. Confirm that the current offer really shows model UC-109 and four downstream data sockets; do not borrow features from the separate BYEASY listing whose model clues conflict.

Before you buy
Does UC-109 have four downstream ports?
The product-specific source record lists four USB 3.0 ports.
Does this profile verify video output, Ethernet or card reading?
No. Those features are not in the saved four-port model layout.
Is the older B0BNN8ZNKX BYEASY listing merged with this model?
No. Its model evidence remains conflicting and it is a separate listing-specific record.
