Our take
CRU3-BK has enough model-specific evidence to identify it as a hub and card-reader combination, but not enough to match it to a particular computer or port requirement. Treat it as a model-search candidate until the current offer confirms the connections.
A buyer willing to verify the exact CRU3-BK offer and its physical port diagram before relying on the hub or card-reader functions..
Buyers who need a verified host connector, downstream port count, USB generation, or named card format before selecting a hub.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- A product-specific article names the CRU3-BK model.
- The source describes both USB-hub and card-reader functions.
- A model search avoids treating the unrelated frozen row as proof.
What to weigh up
- No downstream port count or USB generation is available.
- Supported card formats and computer-side connector are unknown.
- ASIN B01HR3GPO2 remains associated with a WOHENI row, not a confirmed CRU3-BK offer.

Full review: how the features affect your choice
What the features mean for you
The model-level identity is useful but narrow
The saved MySKU article uses the CRU3-BK name and describes the item as a USB hub plus card reader. That is enough to retain the model as a real hub-category candidate. The evidence supports the combination of functions, not a full technical specification. It does not give a reliable port diagram, dimensions, or retail package contents. A buyer should therefore compare the exact CRU3-BK name and visible connectors on the offer rather than treating the two-in-one description as a complete compatibility statement.
Confirm the computer-side connection before ordering
The frozen WOHENI title mentions USB-C, micro-USB, and OTG, but the saved evidence does not map that row to the product-specific CRU3-BK article. Those title details cannot safely establish the model's host plug. Check whether the current offer connects to USB-A, USB-C, micro-USB, or uses a removable adapter, and confirm that its plug matches the computer or mobile device you intend to use. Until that is visible, connector-specific matching should remain unresolved.
Do not infer port count or card formats
The source calls CRU3-BK a hub and reader but does not say how many downstream USB devices it accepts, whether those ports are USB 2.0 or USB 3.x, or whether the reader handles SD, microSD, CompactFlash, or another format. The historical row title is not a substitute because its mapping is unverified. If a keyboard and storage drive need separate sockets, or a camera card must fit a particular slot, inspect a model-matched diagram and packaging before choosing this item.
Keep power and charging claims open
No saved exact-model source establishes a supplemental DC input, an included adapter, a charging port, or laptop charging. A hub can expand data connections without charging a host, and a card-reader combination can have a different power arrangement from a powered desktop hub. Do not select CRU3-BK to meet a power requirement based on the WOHENI title or on the general word hub. Confirm the current offer's power instructions if the connected devices draw more power than a basic peripheral.
Search by CRU3-BK and verify the specific offer
The historical ASIN B01HR3GPO2 belongs to a frozen WOHENI record whose title emphasizes card-reading and OTG, but no inspected source connects that ASIN to CRU3-BK. This page therefore uses a tagged model-search link, not a direct product link. Compare the seller's model name, host plug, USB sockets, supported cards, and package contents before purchase. CRU3-BK is most promising for someone who can verify the physical item; it is a poor fit for a buyer who needs those details settled in advance.
