Our take
Choose ST4300U3C3 when a fixed work area needs four USB 3.0 data connections and three separate charging sockets, with an included 12V/3A supply and a mount for placement. Its main compromise is the split between data and charging: the headline seven ports are not seven data ports. The upstream connector is Type-B, and the historical Amazon identifier is not confirmed for the model.
A stationary desk, bench, or service area that needs four USB data connections plus three distinct charging sockets, and can supply the hub with AC power..
It is not for a USB-C laptop dock, a setup that needs seven data ports, a user seeking video or Ethernet, or anyone who needs a direct verified Amazon listing for this exact model.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- StarTech's manual confirms four USB 3.0 data ports and three dedicated charge-only ports.
- The charging sockets are rated 2 × 1A and 1 × 2A with BC1.2 support.
- A 12V/3A adapter and wall-mount bracket are listed for the fixed hub.
What to weigh up
- Only four of seven downstream sockets transfer data.
- The product uses a USB 3.0 Type-B upstream connector and requires external power.
- Historical ASIN B07FKH35GF was not mapped to the current ST4300U3C3 offer.

Full review: how the features affect your choice
What the features mean for you
How many sockets transfer data?
StarTech's official documentation divides the seven downstream sockets into four USB 3.0 data ports and three dedicated charge-only ports. This matters more than the total port count if you plan to attach storage, a keyboard, or other host-connected peripherals. The three charging sockets do not add data capacity and should not be counted as extra USB hub ports for matching. The manufacturer rates them at two 1A sockets and one 2A socket and identifies BC1.2 support. Keep the two roles separate when comparing this model with a seven-data-port hub.
Does its power arrangement suit your desk?
StarTech lists a 12V/3A power adapter for the hub, so this is intended for a powered desktop or bench setup rather than a lightweight travel splitter. The external supply can be useful when several devices remain connected, but the product documentation does not provide a universal per-device performance guarantee. Reserve an outlet and confirm the supply is included with the specific package. The three BC1.2 sockets are downstream charging ports; they are not a USB-C PD path to charge a laptop. Keep any laptop charging plan separate from the hub's power adapter.
Will the upstream connection fit your computer?
The manual identifies a USB 3.0 Type-B upstream connection at the hub. That connector is common on powered desktop accessories, but the available documentation does not establish the computer-side end of the included cable. Check the required host cable and port before ordering; do not assume a USB-C or USB-A computer connection based only on the hub-side Type-B socket. This product is better considered as a fixed hub attached by a suitable host lead than as a shaped laptop dock. The model's downstream functions do not add HDMI, Ethernet, or card readers.
What does the 5Gbps specification mean?
StarTech lists USB 3.0 data transfer up to 5Gbps. That is the interface link ceiling in the manufacturer's specification, not an independent benchmark and not a separate maximum for each attached device. Four data ports share the hub's connection to the host. The three charge-only sockets do not carry computer data, regardless of whether a device can be physically plugged into them. If a workload involves several drives at once, treat the aggregate host link and device capabilities as limits and check the peripherals' own requirements rather than expecting seven independent high-speed transfers.
Can it be mounted where ports are easy to reach?
StarTech lists a wall-mount bracket and shows the seven-port arrangement in its manual. That can help place the hub under a desk, on a workbench, or near a service station while keeping plugs accessible. Plan cable reach and airflow around the external adapter before fixing it in place. Since the model is not shaped to a particular laptop, installation is about choosing a stable location rather than matching a computer chassis. The current tagged link searches by model because historical ASIN B07FKH35GF was not verified as an exact current offer.
