Your needs, this model
Does it fit your priorities?
Can the original text confirm a supplied USB-A computer route for a new setup?
No. The physical host plug is unconfirmed; this assessment also lacks an established US regional package and stays outside that buying shortlist.
Explore this need in the finder →Can a seven-data-port requirement count the charging outlets?
No. The exact specification provides four data connections and three charging-only outlets; port shapes are also unconfirmed.
Explore this need in the finder →Does the 15W accessory supply establish laptop charging through the hub?
No. The source does not establish a host-charging function or delivered laptop wattage.
Explore this need in the finder →SmartDelux SDU3-P4C3: four data connections and three charging outlets
The SDU3-P4C3 is a compact powered hub whose useful allocation is four computer data ports plus three charging-only outlets. SmartDelux's model-specific product specification states that split directly. Use it when assessing an existing unit or an offer that identifies the exact model, and confirm the physical computer connector and regional adapter package before purchase. Those details are not established by the readable original text used here.
Read the detailed model specification
The original page contains inconsistent headings and copied FAQ references to larger hubs. Its detailed SDU3-P4C3 specification and charging section agree on four data ports and three charging outlets. This assessment uses that explicit seven-socket allocation. It does not turn the page's unrelated ten-port FAQ answer into ten data connections on the smaller model.
The four data ports advertise up to 5Gbps. That is an interface maximum shared through the connection to the computer, not a test result or a guarantee that four drives each receive a separate 5Gbps upstream path. SmartDelux also documents USB 2.0 and older compatibility. Slower peripherals remain useful, while their own interfaces and the computer connection determine the usable rate.
The dedicated charging outlets do not transfer data. They cannot be used to extend the computer's data connection to another hub, and a storage device plugged into one should not be expected to appear in the operating system. Reserve the data group for peripherals that need communication and the charging group for devices that only need accessory power.
Keep the supply budget in view
The package specification includes a 5V, 3A adapter with a 100–240V, 50–60Hz AC input. The stated DC output equals 15W by arithmetic. SmartDelux advertises up to 2.4A for its smart charging function, but that per-device maximum is not an independent allocation that can simply be multiplied across all three outlets while ignoring the supply.
The original text does not provide a complete simultaneous allocation for every charging and data-device combination. Check the demands of the devices that will be active together, particularly when storage and several charging accessories share the hub. The adapter's total rating is the relevant starting point; the manufacturer's general protection claims are not evidence that any arbitrary load combination has been tested here.
This supply serves the hub and accessories. The original material does not document USB-C PD charging back to a laptop. A reader who needs a notebook charged through its docking connection should select a product with that host-power function expressly specified. Also verify the actual regional plug: a universal AC-voltage range alone does not identify the plug supplied with a particular offer.
Check desk fit and cable reach
SmartDelux gives the product dimensions as 117 by 43 by 25mm and the product weight as 105g, distinguishing them from the larger packaging dimensions. The enclosure is aluminum with a black finish. The package includes four anti-slip feet, a data transmission cord, a cord with the power adapter and an instruction sheet.
The maker states a 40-inch data cord and a 60-inch adapter cord. Lay out both routes before choosing where the hub will sit: one must reach the computer and the other must reach the power source. These are useful desk-placement details, but an aluminum enclosure and supplied feet do not establish a wall bracket, clamp or DIN-rail mounting kit.
Use the documented compatibility scope
The original list names 32-bit and 64-bit Windows XP, Vista, 7, 8 and 10, older Mac OS references, UNIX and Linux. It states that no hub driver is needed. The Mac wording is retained as an older Intel-era scope rather than expanded into every later chip, and generic iOS or Android mentions are not converted into a documented iPad computer arrangement.
The available original operating text supports the four-data/three-charge distinction and power arrangement, but does not positively identify the physical host plug or accessory-port shapes. Those connector-specific finder fields therefore remain unspecified. Choose an offer only after its exact cable, data sockets and regional adapter are confirmed. For a new setup requiring an assured USB-A or USB-C route, a fully documented alternative is the more concrete starting point.
