Our take
HB30C3A1GE is a clearly specified data and wired-network hub for USB-C computers. Its included adapter supports hub power, not laptop charging, and the exact model should be found by its StarTech SKU rather than the unmapped historical ASIN.
A USB-C computer setup needing three USB-A data connections and wired Gigabit Ethernet, with a separate power adapter for attached hub devices..
Avoid it if you need HDMI/DisplayPort output, USB-C PD laptop charging, or more than three USB-A data ports from this hub alone.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- StarTech publishes the complete three-port and Ethernet configuration.
- The 5Gbps USB generation and Gigabit link rate are documented.
- The 5V/2A adapter and 30cm cable are listed.
What to weigh up
- There is no PD pass-through or display output.
- The host lead is fixed at 30cm.
- Historical ASIN B07KZY2GVD is not mapped to this model.

Full review: how the features affect your choice
What the features mean for you
Choose it for USB data plus a wired network link
The HB30C3A1GE's defining combination is three USB-A data ports and one RJ-45 Gigabit Ethernet connection from a USB-C host. It can simplify a laptop setup where a keyboard, mouse, or storage device shares space with a wired network cable. StarTech lists Ethernet support at 10/100/1000Mbps and USB 3.2 Gen 1 up to 5Gbps. This is a data and networking hub, not a display dock: the official datasheet excludes DisplayPort Alt Mode. If a monitor connection is central to the setup, choose a product with an explicit video port.
Use the adapter for hub power, not host charging
StarTech includes an AC adapter rated 5V and 2A, and the datasheet lists the three USB-A connections for data and up to 4.5W each. That adapter can supply the hub's peripheral power path independently of relying only on the computer connection. It does not provide USB Power Delivery pass-through to charge the connected laptop. Plan a separate computer charger if host power is part of the desk setup, and do not describe the USB-A outputs as fast-charge ports. The source confirms the adapter arrangement but not a per-device measured outcome.
Match the 5Gbps interface to host and devices
The manufacturer calls the upstream interface USB 3.2 Gen 1 and lists a maximum data rate of 5Gbps, with backward compatibility for older USB devices. That number is the interface ceiling, not a separate 5Gbps guarantee for each of three active ports. The computer's USB-C connection and each peripheral also affect speed. If the attached device supports only USB 2.0, it will use that slower mode; if your host port has a slower data capability, the hub does not create a faster link. Choose it for the documented speed class, not a laboratory transfer promise.
Measure the fixed lead and network reach
The hub has an integrated 30cm USB-C host cable, which avoids carrying a separate host lead but limits how far the enclosure can sit from the computer. The datasheet gives a compact 87 by 45 by 14mm housing and 50g weight. Measure the route from the computer's USB-C port to the intended spot for Ethernet and USB cables before selecting it, especially if the host connection is on the opposite side of a laptop. The short fixed cable is a practical placement constraint, not an interchangeable accessory.
Search by the StarTech model, not the old ASIN
StarTech's model and specifications are well documented, but the frozen ASIN B07KZY2GVD did not resolve to an opened listing that proves it is this SKU. Use HB30C3A1GE in the Amazon search and compare the official three-USB-A-plus-Ethernet diagram, the 30cm USB-C cable, and the included 5V/2A adapter. This reduces the risk of confusing the product with another StarTech hub that adds video or PD. The assessment follows the official page and datasheet and does not claim current price, stock, hands-on use, or buyer-review results.
