Our take
SDU3-P4C3 suits a powered desktop that needs four USB 3.0 data connections and separate charge-only ports, with the included adapter and port roles confirmed.
A desktop user who needs four USB 3.0 data ports plus separate device-charging sockets and can verify the host cable and adapter in the current package..
Skip it when seven data ports, USB-C docking, video outputs, laptop PD pass-through, or a verified current Amazon listing is essential.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- Four USB 3.0 data ports are separate from three charge-only ports.
- SmartDelux lists an included 5V/3A supply and longer data and power leads.
- The SDU3-P4C3 model is distinct from the company's larger 13-port hubs.
What to weigh up
- Only four of the seven downstream positions carry computer data.
- The 2.4A claim does not specify simultaneous combined output.
- Historical ASIN B018HBGGZ6 is not mapped to this official model.

Full review: how the features affect your choice
What the features mean for you
Separate its four computer data ports from its three charging-only ports
SmartDelux describes SDU3-P4C3 as a seven-port powered hub, but the total includes different port roles. Four USB 3.0 sockets transfer data to the computer; three additional smart-charge sockets are intended for charging devices and do not carry data. That distinction matters if you are counting how many drives, printers, or other peripherals will appear to the operating system. For data expansion, the useful count is four. The additional three can help keep charging and computer peripherals physically separate. Check the current product photo for the printed port labels so you do not mistake a charge-only socket for a USB data connection.
Use the included adapter and check its output
The official page lists a 5V/3A power adapter and says the smart-charge function can provide up to 2.4A. That describes the product's published power arrangement; it is not an independent charging-speed test or a guarantee that every device draws 2.4A at the same time. Confirm the adapter is included in the seller's package and the power input matches the unit. The page does not give a total system output budget under simultaneous load, so ask the seller how the available current is shared. A powered hub can reduce how much attached devices draw from the computer, but this source does not publish a detailed power distribution chart.
Put storage on a data port and confirm the host connection
SmartDelux lists the four data ports as USB 3.0 with transfer speeds up to 5Gbps and backward compatibility with older USB devices. The product package description includes a separate data transmission cable, which connects the hub to the computer. That can suit an older desktop or workstation where a short set of USB-A peripherals and external storage needs expansion. The 5Gbps figure is the published interface rate, not a benchmark with all four ports in use. Confirm the host cable's connector and length, and place a high-bandwidth drive on a data port rather than one of the charging-only sockets.
Consider size, cable reach, and placement
The official product page gives an aluminum enclosure and lists a 40-inch data cable and 60-inch power cord. Those details can help plan whether the hub can sit near a monitor, under a desk, or away from the computer's side ports. The manufacturer lists a compact rectangular body and anti-slip feet in the package. The page does not establish resistance to falls or long-term wear, so material and venting descriptions should not be turned into durability guarantees. Measure the route between the computer and power outlet, then check the current seller's included accessories and model marking. Cables that look similar may belong to a different SmartDelux family.
Keep the SDU3-P4C3 distinct from larger SmartDelux hubs
The saved SmartDelux 13-port profiles refer to models with ten USB data ports and three charging-only ports. SDU3-P4C3 is a different official model with four data ports and three charging-only positions. Similar brand names and three-charge-port descriptions do not make their port counts or adapters interchangeable. The current row's Amazon ASIN B018HBGGZ6 returned a cache miss, so there is no source that ties it directly to SDU3-P4C3. Search the complete code and verify the port-face photo. The tagged link above searches the model; it does not assert that the historical Amazon page is the current offer.
