Your needs, this model
Does it fit your priorities?
Can the named Surface setup use HDMI, two USB-A devices and wired networking together?
That is the documented CS32 arrangement, using its fixed USB-A and Mini DisplayPort host pair. HDMI is up to 4K 30 Hz and Ethernet up to 1000 Mbps.
Explore this need in the finder →Can this Surface accessory read SD and microSD at the same time?
Yes. The exact CS32 dual-card section explicitly supports simultaneous reading and writing, within the named Surface configuration.
Explore this need in the finder →Will an ordinary USB-C laptop accept the supplied host arrangement?
No. The actual accessory uses a fitted USB-A plus Mini DisplayPort pair for Surface Pro 4/5/6, rather than a generic USB-C lead.

The CS32 is a fitted accessory for the Surface Pro 4, 5 and 6 generations named by LENTION. Its actual manufacturer photograph shows two fixed computer-side plugs: USB-A and Mini DisplayPort. Both the connector pair and its physical spacing matter. This is not a general USB-C dongle that can be moved to any laptop with a similarly shaped socket.
For the intended Surface setup, the attraction is a useful group of desk connections in one side-mounted body: two USB-A data sockets, HDMI, Gigabit Ethernet and SD/microSD access. Begin with the exact tablet generation and port fit before comparing those features.
The two-plug connection explains the screen function
The USB-A connection supplies the documented USB data route, while the paired Mini DisplayPort connection provides the video path. Keeping both roles clear prevents the HDMI feature from being mistaken for a monitor signal available through any ordinary USB-A port.
The fixed arrangement also affects protective cases and surrounding clearance. Check the actual offered unit against the side of the named Surface. An extension cable, a newer Surface with different connectors or a generic USB-C adapter does not automatically preserve the fitted two-plug setup.
One HDMI screen at the stated timing
LENTION specifies HDMI output up to 4K at 30 Hz for the CS32 and lists lower-resolution use as well. That supports comparing it for a single HDMI display within the documented configuration. It does not establish 4K at 60 Hz or two independent external desktops through this one output.
Choose the screen mode you actually need. For a reader who requires 4K 60 Hz, the correct result is another documented arrangement, rather than silently dropping the refresh-rate requirement because this model also carries a 4K headline.
Two USB-A devices share the data connection
The exact CS32 feature section describes two USB-A devices with advertised USB 3.0 data capability up to 5 Gbps. The manufacturer photograph confirms the two downstream rectangular sockets. They are separate from the USB-A plug used to connect the hub to the Surface.
The interface claim is not a measured transfer result or two independent full-speed host links. Busy storage, the card readers and other data activity share the computer-side route. Count the actual peripherals and check their own power requirements, rather than treating the socket count as an unrestricted power budget.
Wired networking and two-card access are real differentiators
The Ethernet feature is explicitly specified up to 1000 Mbps. That identifies a Gigabit network interface; it does not guarantee the speed of an internet connection or a local transfer. The surrounding network equipment and cabling still matter.
The dedicated dual-card section says SD and microSD can read and write simultaneously. That is useful for a workflow that needs both formats mounted together, and is stronger evidence than simply seeing two slots. Actual copying remains dependent on the cards and the shared data path.
Keep the fitted setup and its limits together
LENTION describes the CS32 as driver-free for the intended arrangement. Connected peripherals and the Surface’s own display settings can still have their own requirements. No USB-C PD input or laptop-charging route is part of the documented connection map.
The page also compares several other LENTION products. Their USB-C charging and video functions should not be transferred to this Surface-specific model. The relevant configuration is the actual CS32 with its fixed USB-A and Mini DisplayPort host pair.
Shortlist this earlier design when a named Surface Pro 4/5/6 needs HDMI, wired networking, two USB-A devices and concurrent card access. Choose another hub for a different physical host, laptop charging or 4K 60 Hz. Its value comes from matching that complete Surface arrangement, not from being a universal expansion accessory.

| Host requirements | Fixed USB-A plus Mini DisplayPort plug pair for Surface Pro 4/5/6 only. The exact manufacturer photo contradicts the broad USB-C wording in the page title; the physical pairing controls this configuration. |
| Screen arrangement | HDMI up to 4K 30 Hz uses the accompanying Surface Mini DisplayPort route. An ordinary USB-A data port alone does not supply that video function. |
| Power and charging | No laptop charging path appears in the complete CS32 map. A supplied mains adapter and detailed shared peripheral-power budget are not established. |
| Data and device limits | Two downstream USB-A 3.0 sockets are advertised up to 5 Gbps, plus Gigabit Ethernet and simultaneous SD/microSD use. The computer-side USB-A plug is not a third downstream data port. |
| Installation | Check the named Surface generation, both side ports, physical spacing and case clearance. This is a fitted side accessory, not an interchangeable USB-C laptop dongle. |
