Our take
The RSH-A104 may fit a user who wants four USB-A data connections, port-level switches and an included 5V adapter, and whose host has USB-A. It is not a match for someone seeking a monitor hub, a USB-C-only host adapter, an Ethernet jack or a high-power USB charging station. Confirm that the current listing identifies RSH-A104 and the expected brand before relying on these specifications.
A USB-A host user who wants four data ports with local switches and an external adapter, and can verify the current listing's brand and model..
Skip it when you need HDMI, Ethernet, card reading, a USB-C host, or a dedicated high-power charging station.

Full review: how the features affect your choice
What the features mean for you
Four data ports with one USB-A host connection
RSH Tech identifies RSH-A104 as a powered four-port USB hub that connects to a computer through a USB-A male plug. The four downstream sockets are described as USB 3.2 Gen 2 data ports; the model is suited to a compatible PC or Mac that needs several USB-A peripherals or storage devices. The manufacturer page does not describe HDMI, Ethernet, SD readers or USB-C downstream sockets, so treat it as a data expansion hub rather than a laptop dock. A USB-A host connection also rules it out for computers that have only USB-C ports unless a separate, suitable host adapter is used. Check the exact upstream connector before selecting it.
Interpret 10Gbps as the interface ceiling
RSH Tech calls the ports 10Gbps USB 3.2 Gen 2 and says the hub turns one USB 3.1 Gen 2 Type-A port into four data ports. That is the stated maximum link rate; it does not mean each of four connected drives receives a separate full 10Gbps at once. The computer's upstream port and each device must support the same generation, and transfers may share the hub's connection. The reviewed materials do not provide independent benchmark results, so choose it for the labeled interface and port count rather than assuming a particular copy time. Older USB peripherals may still be relevant, but the source's backward-compatibility details should be checked against the exact device if a legacy connection is important.
Use external power for the hub's stated purpose
The manufacturer says a DC 5V adapter is included to support devices that draw more power than a bus-powered hub may comfortably supply. Its specifications list an adapter output of 5V/2A. That does not mean 10W is available independently to each of the four ports; no per-port current table was present on the official page. Confirm that the selected package includes the correct adapter and that its plug matches the hub. The manufacturer page presents the downstream connectors as data ports. Do not treat them as dedicated phone fast-charge sockets or infer charging protocols not named in the documentation.
Individual switches and LEDs change everyday use
RSH Tech describes a switch for each USB port and an LED indicator. It says a light press turns a port on and a two-second press-and-hold turns it off. For a desk with devices left connected, this can make it easier to isolate one accessory without unplugging cables. The LEDs are status indicators, not evidence of transfer quality or a successful backup. If you need to turn connected hardware off on a schedule or remotely, that behavior is not documented here. The controls are physical and local; users should inspect the hub's labeling and manual before relying on a particular button behavior for sensitive storage or connected equipment.
Keep RSH-A104 and the two Amazon ASINs distinct
The row's title and an indexed source identify an ikuai RSH-A104 associated with B09Y1VV9QN. The RSH Tech page verifies an RSH-A104 product and links to Amazon B09XR353QL under the Rosonway brand. Those records share a model code, but the different ASIN and brand mean the RSH Tech link does not prove that the frozen ikuai listing is the same current seller offer. The direct B09Y1VV9QN Amazon page did not return content, so the affiliate route searches the RSH-A104 model and retains the frozen ASIN only as a query clue. Confirm the brand, model marking, port switches and adapter before ordering. This profile uses specifications, not the video reviewer's personal testing or opinion.

Before you buy
Does RSH-A104 have HDMI?
No. RSH Tech's RSH-A104 feature list documents USB data, switching and power, but no HDMI or other display output.
Does it include an adapter?
RSH Tech specifies a 5V/2A adapter.
Is ikuai B09Y1VV9QN the same current Amazon offer as Rosonway B09XR353QL?
The available sources do not establish that; the two ASINs remain separate.
Where can I check the current price?
