Our take
UGREEN 20805 is a four-port USB 3.0 data hub with a separate USB-C power socket described by a reseller. It is a candidate for peripheral expansion only after host and power details are checked.
A buyer seeking four USB 3.0 data ports who can verify the computer-side plug and power setup for the exact 20805 variant..
Buyers who need a known host connector, a confirmed included adapter or total load budget, video, networking, card readers, or laptop charging through the hub.
Pros & cons

Full review: how the features affect your choice
What the features mean for you
Four downstream data ports are the core
UGREEN's conformity document identifies CM473 as a four-port USB 3.0 hub and groups SKU 20805 with other CM473 variants. A product-specific reseller record maps the historical row to 20805 and lists four USB 3.0 ports. That is a straightforward use for a computer that lacks enough connections for a mouse, keyboard, flash drive, or storage peripheral. The reseller advertises up to 5Gbps, but this is a specification ceiling rather than a measured result for each port. The host controller, cable, drive, and simultaneous activity affect actual transfers. Compare the exact model code and port face before choosing it for a storage workflow.
Do not confuse the extra USB-C socket with the host plug
The reseller describes an auxiliary USB-C power input, but the saved product record does not provide a complete diagram of the upstream connection. A USB-C power socket does not prove that the hub connects to a computer through USB-C. Check the selected offer's host cable and port labels, especially if the computer has only USB-C or Thunderbolt ports. The product family includes several SKUs, and the manual groups 20805 with 20841 and 20892 without proving that every cable or enclosure is identical. Treat the computer-side connector as unknown until the exact 20805 unit is shown.
Auxiliary power is useful only when its limits are known
The product listing says the additional USB-C socket helps power the hub when devices draw more current, but it does not give an overall current budget or confirm that a power adapter comes in the package. Four ports do not mean the hub can reliably supply four demanding drives at once. If external SSDs or other high-draw devices are part of the setup, ask which supply is required and what combined output is supported. This auxiliary input is for the hub according to the listing; it is not described as USB PD pass-through to charge the host computer. Buyers who connect only low-power peripherals may have less need for the extra power path.
Keep 20805 distinct from the other CM473 variants
The conformity material identifies a family of related CM473 SKUs, while the reseller record specifically maps the row to 20805. That makes the SKU important: a neighboring four-port UGREEN hub may use a different host plug or power arrangement. The saved evidence for 20805 includes an auxiliary USB-C power port, while the 20841 records describe a USB-C host connection and conflicting wording about another USB-C port. Do not transfer the 20841 connector role to this model. Compare the code printed on the offered item and its complete port diagram before ordering.
Other dock functions are not part of the documented layout
The product-specific records describe a four-port USB hub and an auxiliary power connection. They do not document HDMI, Ethernet, SD, or microSD on the 20805 model. If a screen, wired network, or card reader is important, choose a hub whose exact model page lists those ports. The label four-port describes the data-expansion role rather than a full dock. Keeping this distinction clear can prevent a buyer from assuming features from a visually similar UGREEN hub or from a different CM473 SKU. This assessment uses the saved port descriptions and does not infer extra functions from a family name.
Who should consider UGREEN 20805
20805 may suit someone who needs four USB 3.0 data ports and can confirm the upstream plug and power setup from the current package. It is a poor fit when host connector type, an adapter-in-box guarantee, a known total power budget, laptop charging, video, Ethernet, or card access is essential. Desertcart associates the historical ASIN with 20805, but the Amazon detail page did not verify a current exact offer. Search by the model and compare the SKU, cable, and auxiliary port before buying. This review relies on a maker declaration and reseller specifications; it makes no personal test, current stock, or customer-rating claim.
