LENTION CB-C31 USB-C Hub review

Four USB-A peripherals without a video-dock port mix

The CB-C31 is useful when a USB-C laptop mainly needs more places for familiar USB-A devices. Its exact maker description identifies four USB 3.0 sockets and a separate USB-C charging connection. The manufacturer photograph confirms those four rectangular outputs and the attached USB-C lead that connects the hub to the computer.

The deciding distinction is its focus. This is a data-and-power adapter, rather than an HDMI dock or a built-in camera-card reader. It makes sense when the devices you already use are USB-A and the laptop also needs a supported charging path through the accessory.

Count the devices you use together

LENTION explicitly describes accessing four USB accessories at the same time. A wired keyboard, mouse, flash drive and another supported peripheral are a different requirement from several USB-C drives. The computer-side USB-C plug does not create a downstream USB-C data socket for that latter collection.

Check the actual plug bodies as well as the count. A wide flash drive or receiver can need more neighboring space than a narrow cable connector. The most useful four-port arrangement is the one that physically accommodates the devices you intend to leave connected.

The 5 Gbps figure describes the interface

The USB-A data sockets are advertised up to 5 Gbps. That is their interface capability, not four independent full-speed links back to the laptop. All connected devices still communicate through the upstream computer connection.

For ordinary peripherals and occasional file transfers, the number and type of sockets may be the main consideration. If several busy storage devices or a 10 Gbps interface are essential, retain those needs when comparing alternatives. A compact hub should not be assigned a faster data class merely because it uses a USB-C host plug.

Charging is a separate supported connection

The model-specific description says the USB-C charging port can pass up to 60 W to a USB Power Delivery laptop while connected accessories operate. That is a stated maximum for the described pass-through function, rather than a measured charging result for every computer. The laptop, external power source and cable must support the intended arrangement.

The inspected text does not establish a supplied mains charger. In particular, the phrase “charging adapter” in the product title should not be read as proof that a wall charger comes in the box. Check the actual package if a complete supplied charging kit is one of your requirements.

Do not borrow features from neighboring models

The product page compares this hub with several LENTION models that add their own HDMI, Ethernet or card-reader functions. Those columns describe different products. The CB-C31 column and its own feature list identify four USB-A data sockets and the charging path.

If a screen or built-in SD reader is part of the job, choose a port map that includes it explicitly. A separate USB card reader can be attached as a peripheral, but it occupies one of these four data sockets rather than adding a free built-in reader function.

Check compatibility and peripheral power

The maker lists specific USB-C MacBook generations and selected Surface, Windows and Chromebook examples. Older MacBook models without the required connection are excluded. Those named examples should not be expanded into a guarantee about every later Apple chip or operating-system version.

LENTION says no extra hub drivers are required and specifically excludes Apple SuperDrive. That exclusion remains relevant even though the page also discusses powering accessories while pass-through is connected. A general power feature does not override the exact device restriction.

Shortlist the CB-C31 when four USB-A data devices and the documented up-to-60 W pass-through role fit a supported laptop. Choose another adapter for downstream USB-C data, video, built-in cards or an established included charger. That focused comparison makes its relatively simple port mix useful.

LENTION’s exact CB-C31 description, model column and compatibility guidance establish this configuration.
