Our take
A compact, well-documented mix of three USB-A data ports, two card readers and 4K30 HDMI; choose it only if those limits match the host and monitor.
A USB-C laptop user who wants three USB-A data connections, SD and microSD access, and a 4K30 external display from one compact hub..
Buyers who require 4K60, a verified exact Amazon listing, a specified net laptop charging rate, or a charger confirmed in the package.

Full review: how the features affect your choice
What the features mean for you
Start with the three data ports and two reader slots
CB-C36B is a compact multiport hub for someone who needs a small set of standard USB-A peripherals plus camera-card access. LENTION lists three USB 3.0 ports and separate SD and microSD readers, so the seven-in-one label includes different functions rather than seven interchangeable USB sockets. The page claims simultaneous reading and writing on the two card slots. That could reduce the need to carry a separate card reader, but the actual workflow still depends on the host operating system and card format. Compare the exact port face and choose the Silver variant if color matters; LENTION lists it alongside Space Gray and Rose Gold.
Set a realistic display expectation
The official page specifies HDMI up to 3840×2160 at 30Hz, with lower resolutions at 60Hz. It does not claim 4K60. That can be suitable for presentations, video playback or a secondary monitor where 30Hz is acceptable, but it is a poor match for buyers who require a 4K60 desktop. LENTION describes compatible full-featured Type-C hosts and names particular MacBook generations, but a USB-C-shaped port alone does not ensure video. Verify that the computer supports DisplayPort Alt Mode or the relevant Thunderbolt function, then compare its output support with the display and cable before purchasing.
Treat speed ratings as interface claims
The three USB 3.0 sockets are listed up to 5Gbps, while the dual card readers are claimed up to UHS-I/104MB/s with both cards able to read and write at once. These are maximum specifications, not guaranteed transfer results. Actual throughput varies with the host, cable, drive, card and concurrent workload. The page does not give a benchmark showing all three USB ports and both readers reaching their maxima simultaneously. For ordinary keyboard, mouse, flash-drive and photo-card use, the layout is clear enough to judge against a desk setup. If high sustained SSD speed is essential, ask for the exact manual and check the hub's shared upstream bandwidth.
Understand the PD port as pass-through input
LENTION advertises a USB-C power-delivery connection up to 100W and describes it as pass-through charging. The listing does not establish net wattage delivered to the laptop after the hub and connected devices draw power, and it does not say a charger is included. Match a suitable USB-C PD adapter to the computer's power needs, then confirm the current listing's port diagram. Do not use 100W as the expected laptop charge rate under every load. The page also warns that the hub does not support Apple's SuperDrive, which is a useful compatibility limitation for an older optical-drive workflow.
Check the model and host generation before ordering
The official product page ties the feature set to CB-C36B and names MacBook Pro 2016–2020 and MacBook Air 2018–2020, along with Surface and other full-function USB-C devices. It says earlier MacBook Air/Pro generations are not supported. Treat those host examples as a compatibility list, not universal support for every USB-C device. The historical B09YTFK15N ASIN is not cross-linked to the current official page, so search by the exact model and compare the silver color, port layout and host connector. This review uses LENTION specifications and makes no personal testing or current-offer claim.
