LENTION CB-C36B Seven-in-One Hub review

A small workstation hub with genuinely simultaneous card access

The CB-C36B is useful when a compatible USB-C laptop needs one HDMI screen, a few USB-A devices and both card formats available together. Its model-specific description identifies three USB-A data sockets, SD and microSD readers, HDMI and a separate charging connection. The manufacturer photograph confirms that complete port mix.

The deciding screen limit is 4K at 30 Hz. This is a different configuration from a hub documented for 4K 60 Hz. Keep the actual resolution and refresh-rate requirement attached to the comparison rather than selecting only by a 4K headline.

Choose the screen timing that fits the task

LENTION specifies up to 3840 by 2160 at 30 Hz and separately lists 2560 by 1600 and lower resolutions at 60 Hz. Those are different display modes, not interchangeable versions of one claim. The computer, HDMI connection and screen must support the selected arrangement.

There is one HDMI output. The charging socket and USB-A data ports do not create additional native monitor outputs. For two independent external desktops, start with a complete multi-screen arrangement documented for your particular host.

Three USB-A data devices share the upstream connection

The exact CB-C36B text describes three USB-A peripherals with USB 3.0 capability up to 5 Gbps. This can suit a keyboard, mouse and another ordinary device while a display is connected. The computer-side USB-C plug is the host connection rather than a fourth downstream data socket.

The 5 Gbps figure is an interface rating, not a measured copying result or a separate full-speed host link for every device. Consider what the connected devices do simultaneously. Several busy drives create a different workload from input peripherals and an occasional file transfer.

Both card slots can be active

The maker explicitly supports simultaneous reading and writing of SD and microSD cards. That is a meaningful distinction for a workflow that needs both formats mounted together. Two visible slots alone would not establish this behavior, but the own model description does.

The reader capability is described as UHS-I, up to 104 MB/s. That is an advertised interface ceiling rather than a guarantee for every card or file set. Card traffic also shares the computer-side data connection with the USB peripherals.

Charging is a supported external-power role

The USB-C Power Delivery connection is advertised as supporting up to 100 W pass-through to the laptop while also supplying connected accessories. This is the maker’s stated maximum for the described function, rather than a measured fixed output for your particular setup. Use an appropriate charger and cable for the actual host.

The inspected material does not establish a supplied mains charger. The USB-C charging socket is not separately specified as a downstream data connection, so do not count it as another direct port for a USB-C drive alongside charging.

Keep exact exclusions with the recommendation

LENTION names USB-C MacBook generations and selected Surface, Windows and Chromebook examples. Older MacBook Air and Pro generations without the required connection are excluded. A broad year range should not be expanded automatically into every Apple-silicon configuration.

Apple SuperDrive is specifically unsupported. That restriction remains even though the page discusses power for attached accessories. A general charging feature does not override the named device exclusion or establish an unlimited peripheral-power budget.

Shortlist the CB-C36B for its documented one-screen mode, three USB-A connections and concurrent card readers on a supported host. Choose another adapter for 4K 60 Hz, several independent screens, Ethernet or downstream USB-C data. Its value lies in fitting that complete connection pattern, rather than collecting functions you do not need.

LENTION’s exact CB-C36B feature list and manufacturer photograph establish the simultaneous-card and display distinctions discussed here.
