Full review: how the features affect your choice
What the features mean for you
Pick it for front-access expansion on the listed iMac
The IMC01H is a clamp-style expansion hub intended to attach at the lower edge of a 24-inch 2021 iMac. Its front-facing ports can make flash drives, card slots, and other connections easier to reach than the iMac's rear ports. The product description is specific about that host and attachment method, which helps filter the product: this is not a generic hub for any laptop with USB-C. Confirm the iMac generation, edge geometry, and dual-port spacing before buying. The current model family is identified, but B09QQ197XZ is not linked to it by the inspected sources.
Match HDMI output to the external display
The model-specific catalogs describe an HDMI output up to 4K/60Hz. That is a useful advertised limit, but it does not guarantee that every resolution, refresh rate, HDR mode, or color depth works from every host. The iMac model, operating system, cable, and display all affect the result. The reseller page also describes a high-speed USB-C function with a separate 6K/60Hz claim; that claim concerns its stated USB-C display path and should not be confused with the HDMI port. Check the exact output diagram and current manual if you need multiple screens or a particular mode.
Count USB data ports by type and rate
The catalog describes four USB expansion ports, including a 10Gbps USB-C port, a 5Gbps USB-C port, and two USB-A 3.0 ports. This gives more than a simple two-port splitter, but the product pages do not show a complete shared-bandwidth table or independent throughput test. A keyboard and mouse make different demands from an external SSD. If you intend to connect several fast drives, verify which port is the 10Gbps connection and whether transfers share host bandwidth. Treat the figures as advertised maximums rather than a promise of simultaneous full-speed operation.
Use SD and microSD with capacity details still to check
The reseller says SD and microSD can be read at the same time, which can help when ingesting material from two card formats without a separate reader. The inspected product details do not specify maximum card capacity, UHS class, or sustained read speed. A photographer should check those limits against their card collection before relying on this hub in a regular workflow. The slots are part of the hub's expansion count, not additional USB data ports. Confirm their position and access clearance from current photos, especially if the iMac sits close to a wall or the clamp fits tightly under the screen.
Check the clip and paired host connector before installing
The model is described as using two USB-C host connections and a clamp mount. That can produce a tidy installation when the computer has the matching port pair and the hub's clip seats correctly. A protective shell, nonstandard stand, or different iMac generation can change the fit. Neither the frozen row nor Danawa's specification table supplies detailed measurements for the clamp or connector spacing. Review current photos and dimensions, then compare them with the iMac's lower edge and port placement. Do not assume the IMC01H will work on a MacBook or on an iMac with a different chassis.
Search the model number and keep the historical ASIN unresolved
Hagibis IMC01H is a supported model identity, but inspected reseller and catalog material does not identify B09QQ197XZ. Another indexed IMC01H page uses a different ASIN, which is a reason to avoid replacing the candidate identifier or merging the records. The tagged search uses the model name and clamp-hub function. Before choosing a result, verify the iMac size, port layout, USB-C host connection, HDMI mode, and card slots. This review is based on manufacturer and retailer descriptions, not hands-on testing, user-review summaries, current price, stock, or sales.
