Our take
UGREEN 20841 is a compact USB-C-host hub with four USB-A outputs. Its port count is clearer than its cable and supplemental power details, so verify the exact package before relying on those parts.
A USB-C computer owner seeking four USB-A data ports who can verify the exact 20841 cable and supplemental power role..
Buyers who require Ethernet, HDMI, card readers, an established external-power budget, or an exact current US Amazon listing without checking the model code.
Pros & cons

Full review: how the features affect your choice
What the features mean for you
Four USB-A outputs sit behind a USB-C host
UGREEN's 20841 records describe a USB-C host connection and four USB-A downstream ports using USB 3.2 Gen 1. This can suit a laptop with a few USB-C sockets that still needs a mouse, keyboard, thumb drive, or other USB-A peripherals. The physical host connector matters: the similar CM473 SKU 20805 has a different saved connector and power description, so the shared family name does not make the variants interchangeable. Check the selected item for model 20841 and the USB-C host lead before ordering. The four-port count is useful for basic expansion, but it does not add HDMI, Ethernet, or card reading on the documented model.
Treat the 5Gbps figure as an interface ceiling
The product pages identify USB 3.2 Gen 1 and list transfer up to 5Gbps. That number is a specification, not a measured result for every connected device or a guarantee that four ports each deliver the full rate concurrently. The host port, cable, attached drive, and active workload all affect actual transfer. For a mouse and keyboard, the rate may not be the deciding factor; for external storage, verify that the computer supports the same generation and plan for shared upstream traffic. The source records do not include benchmark results. Use the rate as a compatibility clue, not as a promise about a specific file-copy time.
Check the cable length against nearby ports
UGREEN Poland lists a 15cm lead, while UGREEN Online describes the 20841 cable as 20cm. That difference can affect whether the hub reaches a laptop's usable side port and how close it sits to adjacent USB-C connections. Both listings describe a short attached lead, but the exact length for the selected variant is not settled. The aluminum enclosure may suit a compact desk or travel bag, though buyers should check the current photos and package label rather than assume every CM473 SKU uses the same cable. Measure the space and check the cable end before deciding where the hub will sit.
The extra USB-C power description needs confirmation
One listing says the 20841 has no separate power port; another description refers to an additional USB-C connection for hard-drive support. The saved evidence does not provide a consistent port diagram or a full power budget. Do not assume the extra connection is a laptop PD path, a data port, or a way to power several drives unless the exact offer and manual confirm it. Buyers planning to attach portable storage should verify whether an adapter is needed, what supply is supported, and whether any current limit is listed. The profile leaves the role unresolved instead of transferring the 20805 auxiliary-power description to this model.
Keep the two CM473 SKUs separate
The 20841 variant is documented with a USB-C host and four USB-A outputs. The related 20805 profile has a separate USB-C auxiliary power input described by its reseller record, and its host connector is unknown. These differences are enough to keep separate product identities even though both share the CM473 family code and four-port description. Match the printed 20841 number, host plug, and complete side view. A shared family name is not evidence that cable length, external power, or package contents are the same across all listed SKUs.
Who should consider UGREEN 20841
This model may suit a USB-C laptop owner who wants four USB-A data ports in a compact hub and can confirm the exact cable and power details. It is a weak fit when Ethernet, video, card slots, a proven external supply, or a precise current Amazon.com offer is required. Amazon Mexico associates B0919N7HVF with 20841, but that does not prove a current US offer. Search by the model code and inspect the connector, cable length, and extra-port labeling.
