Your needs, this model
Does it fit your priorities?
Will four USB-A accessories all have 5 Gbps capability?
No. Three ports support 5 Gbps, while the fourth is USB 2.0. Four fast-port requirements exclude this model.
Explore this need in the finder →Can it add a 4K HDMI screen and an SD reader?
Yes, from a suitable USB-C computer the manual supports one HDMI display at 3840×2160 and 30Hz together with the hub/card functions.
Explore this need in the finder →Does the power input guarantee laptop charging?
No. The reviewed original guide describes powering the hub for attached devices and does not establish a computer-charging capability. It cannot pass a required laptop-charging answer.

The Sabrent DS-UHCR combines several small-adapter jobs on a single USB-C computer connection. It provides HDMI, SD and microSD readers, three USB 3.0 Type-A ports and a fourth USB 2.0 Type-A port. A separate USB-C socket supplies auxiliary power to the hub. The original manual identifies this exact layout rather than treating every connector as another equivalent data port.
This arrangement suits a laptop user who needs a single external screen, occasional camera-card access and several traditional accessories. It is less appropriate when every USB device needs the faster speed class, or when the main purpose is to charge a laptop through the adapter. The slower fourth port and the purpose of the power input are the two details to settle first.
Put storage on the three faster ports
Three USB-A sockets are rated for transfers up to 5 Gbps. The additional USB-A port is USB 2.0, which the manual suggests for a mouse, keyboard or similar accessory. Keeping low-bandwidth peripherals on that socket leaves the faster connections available for storage.
Four physical USB-A sockets therefore do not satisfy a requirement for four 5 Gbps ports. The advertised speed is also a line-rate capability, rather than four independent measured transfer channels. The computer connection is shared by the hub's active functions. Choose around which devices will work together, especially if large file transfers are important.
The SD and microSD readers give two card-format options, but the reviewed original manual does not establish that both can operate simultaneously. A workflow requiring both cards mounted together needs a reader with explicit independent operation. Card-slot count alone does not answer that question.
One HDMI output, with 4K limited to 30Hz
The DS-UHCR supports one HDMI display at up to 3840×2160 and 30Hz. The manual also states compatibility with 1080p displays, but it does not provide a complete resolution and refresh-rate table. We therefore retain the exact 4K30 capability without turning the general 1080p statement into an undocumented refresh-rate promise.
The computer must supply the necessary video function through USB-C. The instructions describe a USB-C laptop or PC providing the hub's full data and HDMI extension features; a connector that carries only charging or ordinary data does not become a video output merely because it fits. Windows OS and Mac OS are named, without a current Apple-chip-by-chip compatibility table.
There is no second HDMI, DisplayPort or USB-C video output in this arrangement. If two independent external desktops are essential, choose a dock with a specifically documented multi-display configuration for your computer.
Do not confuse auxiliary hub power with computer charging
The original manual describes the extra USB-C socket as a power input for operating high-powered devices. Its setup instructions say to connect power to the hub when required. They do not establish a numerical Power Delivery output to the laptop or a verified laptop-charging function.
That distinction matters because some historical retail descriptions use broader charging language. We do not convert that into a guarantee. If your computer must charge through the same adapter, select a model with an explicit supported host-charging arrangement. The DS-UHCR package lists the hub, its built-in USB-C cable and the manual, without an external supply.
A practical choice with a deliberately limited role
Sabrent describes the hub as plug-and-play with no driver installation needed, while recommending current computer drivers and updates. Connected peripherals can still have their own normal software requirements. The attached host cable keeps the adapter together as one piece, but cannot be detached for replacement or a different length.
Choose the DS-UHCR for one HDMI screen, card access and a mixed group of USB-A devices where three fast ports are enough. Choose differently for a verified laptop-charging path, simultaneous-card transfers or several independent screens. Its value is the combination it actually documents, with each connector assigned its real job.
