Our take
CB-H30 is a limited-evidence four-port USB 3.0 mini hub. TechByte identifies the model and describes a small plastic body and short cable, but it is a third-party article rather than a manufacturer specification. The source contains performance tests and old price information; neither is used here. It gives enough to compare the stated port count and physical footprint, but not enough to confirm the host connector, power path, or current Amazon identity.
A buyer comparing a small four-port USB 3.0 hub who can verify host connector and current model identity from the live offer..
Do not choose it when a verified host connector, external-power arrangement, HDMI, Ethernet, card reader, PD rating, or current ASIN-to-model crosswalk is required.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- The article specifically names model CB-H30 and four USB 3.0 ports.
- It gives a compact 9 × 3.8 × 2.1cm body and roughly 18cm lead description.
- The review avoids adopting the article's test results and historic price as product facts.
What to weigh up
- The source is a dated third-party description, not a maker specification.
- Host connector and power arrangement are not documented in the saved packet.
- Historical ASIN B01A2ZF1LU is not mapped to a current offer.

Full review: how the features affect your choice
What the features mean for you
Compare it as a small four-port hub
TechByte's model-specific article describes CB-H30 as a four-port USB 3.0 hub. This layout can be relevant when a computer needs additional sockets for a mouse, keyboard, flash drive, or other everyday USB accessory. The article does not provide a manufacturer port-by-port diagram, so compare the live product photos with the four-port description before relying on a particular configuration. It is a narrower option than a multiport dock: the saved record documents USB expansion, not display, network, or card-reader functions.
Consider the short lead and compact body
The article lists a housing of about 9 by 3.8 by 2.1 centimeters and a cable around 18 centimeters. A small body can sit close to a laptop or desktop port, which may suit a neat workspace with several nearby accessories. The short cable also limits placement distance and can leave the hub hanging if the computer's port is awkwardly positioned. Check the current listing's exact cable and connector photos, since the source does not identify which host plug is fitted or whether a different revision exists.
Do not infer speed from the article's testing
The article's product description calls the hub USB 3.0, but its later paragraphs report the author's own test results. Those measurements are not used as catalog facts or represented as testing performed for this guide. A USB 3.0 label describes an interface generation; actual transfers depend on the host, device, file pattern, and shared upstream connection. Choose the model only if the port count and host connection shown by the current offer meet your needs, and do not use old third-party measurements as a guarantee of present performance.
Treat charging and power as unknown
The saved article does not document a dedicated auxiliary power input, a USB-C PD pass-through port, or a host-delivered laptop charging rating. It mentions charging behavior in its editorial text, but that does not establish a model-specific port or supported power budget. Keep the power profile unknown until a clear manufacturer document or current product diagram identifies it. If attached devices need more power than the host supplies, verify their requirements and use a suitable independent supply rather than assuming the hub can serve as a charger.
Keep the third-party source boundary visible
TechByte identifies CB-H30 and supplies basic physical and port details, but it is not AUKEY's official product page. The article was published in 2016 and updated in 2019. Its test section and historic price are deliberately excluded; this review does not summarize those results or call them current. That limited source is enough for a cautious model-specific layout entry, not for broader claims about reliability, throughput, charging, or today's listing identity. Keep that distinction in view when comparing this hub with models documented by a manufacturer manual.
Search by CB-H30 and verify the current offer
Historical Amazon ASIN B01A2ZF1LU was not mapped to a current exact offer. Use the tagged CB-H30 search and compare the model name, port count, short cable, and plastic body in the result before purchase. The available source supports a four-port USB 3.0 description, but does not verify current stock, a new seller's variant, or a host connector. If the current offer omits the model number or shows a different layout, treat that as a different or unresolved listing rather than silently inheriting these facts.
