Our take
CB-C31 may suit a laptop owner who needs four USB-A data ports and up to 60W PD passthrough in a simple USB-C hub. It is a poor fit when HDMI, Ethernet, audio, memory-card slots or more than the documented charging ceiling are essential. Verify host compatibility and the exact offer before buying.

Full review: how the features affect your choice
What the features mean for you
Buy it for extra USB-A data sockets
CB-C31 is a straightforward USB-C host hub for adding four USB 3.0 downstream connections. LENTION describes uses such as a keyboard, mouse, flash drive or hard disk and lists up to 5Gbps for the USB data ports. This is a narrower role than the row's word “multiport adapter” may suggest: the official CB-C31 comparison table does not list HDMI, Ethernet, audio, SD or microSD. The fifth advertised function is the USB-C power pass-through input, not another ordinary downstream data port. If you need video and card readers, choose a different LENTION model rather than assuming that every CB-C series hub shares the CB-C16s or CB-C36b port layout.
Keep the 60W figure on the input side
LENTION says the Type-C charging port can pass through up to 60W to a USB Power Delivery laptop, and that it can provide extra power to connected accessories. That is the manufacturer's passthrough claim, not a measured output guarantee for every charger and host. The page says the hub does not require an external power supply for ordinary operation; it does not establish that a charger is included with the Amazon offer. If the connected laptop requires more than 60W, compare that requirement before relying on this model. Use a compatible USB-C charger and cable and confirm the current seller's package contents.
Confirm the USB-C host is fully featured
The official page lists compatibility with MacBook Pro/Air models, Surface, Chromebook and other full-function Type-C devices. A Type-C connector alone does not guarantee every hub function works on every device. Check the computer's USB-C data support and charging behavior, particularly if it is an older laptop or a tablet. The product is described as plug-and-play and is specifically marked not for Apple SuperDrive. Buyers should verify that their peripherals use standard USB-A connections and that the computer can accept the hub's host plug before choosing it for a permanent setup.
Do not expect display, Ethernet or card-reader outputs
CB-C31 may be a useful choice when the problem is simply too few USB-A ports, but it does not cover the jobs handled by a larger dock. LENTION's own comparison table uses dashes for its HDMI, Ethernet, card-slot and audio functions. Its four USB 3.0 outputs are data ports; the additional USB-C connection is for PD pass-through. A buyer who expects one cable to add a monitor and wired network should compare CB-C31 with a separate LENTION dock model whose official table explicitly lists those ports. Do not use the “5-in-1” label as proof that the product has five data outputs.
Verify the ASIN and finish independently
The frozen row names CB-C31 and silver, and LENTION's official model page confirms both a CB-C31 hub and silver as an available finish. The exact Amazon ASIN B07W5GSBVG did not return listing content, so this source does not establish that the historical offer is the same current Amazon item. Search for CB-C31 and verify the product markings, finish and port face. The tagged link avoids treating the inaccessible ASIN as a guaranteed current offer. This review relies on LENTION's model page and does not claim personal testing, availability, price or customer-review trends.
