Your needs, this model
Does it fit your priorities?
Can my base M2 MacBook use one HDMI screen and two fast USB-A peripherals?
Yes, on the documented one-screen route. Two USB-A sockets are rated up to 10 Gbps and HDMI up to 4K 60 Hz. This does not create a second independent screen on base M2.

Yes. The exact page and original guide explicitly support simultaneous use of both card slots.
Explore this need in the finder →Can a base M3 MacBook run two independent screens with its lid open?
The maker’s dual-display condition for M3 is clamshell mode. This open-lid request does not match that documented arrangement.
Explore this need in the finder →A fitted MacBook hub with two very different USB-C outputs
The silver ST-HUCPHSS Pro Hub Slim is useful when a compatible MacBook needs an HDMI screen, fast data connections and card access without a separate desktop dock. It connects through two adjacent USB-C ports on the computer. That fitted arrangement is the first buying decision: check the actual side-port layout and any protective case before comparing the sockets.
The most important distinction is between the hub’s two downstream USB-C roles. One is a full-function USB4 pass-through connection. The other is a 10 Gbps data-only socket. Only the USB4 connection supplies the documented display and charging functions; the ordinary data socket cannot take over those jobs.
Start with the computer and the number of independent screens
The exact product page limits base M1 and M2 Macs to one external display through this arrangement. Two physical video connections do not remove that restriction. If two independent desktops are essential, selecting this hub by output count alone gives the wrong answer.
The maker separately permits extended dual-display use on M3-based Macs in clamshell mode. That means the lid condition is part of the configuration. The page does not give one common resolution-and-refresh table for both displays together, so its individual output maxima should not be joined into a promise of two identical high-resolution screens.
One HDMI screen is the simpler documented route
The HDMI output is rated up to 4K at 60 Hz. The original guide calls for the HDMI connection as a distinct output, while the USB4 port can support a compatible USB-C display. Check the monitor’s actual input and use a suitable connection for that route.
If you only need one HDMI screen, the USB4 port remains available for another supported role. It can accept the appropriate charging connection, while the separate USB-C data socket remains available for a peripheral. If USB4 instead serves a data device, do not count that same physical socket as an independent charger input.
Count fast data sockets within the selected arrangement
There are two USB-A data sockets advertised up to 10 Gbps and one separate USB-C data socket at the same advertised rate. The USB4 pass-through connection is listed up to 40 Gbps for its data role. These are interface capabilities, not measured storage results or independent full-speed channels for every device at once.
The distinction matters for a two-USB-C-drive setup. You may use the USB4 connection for data alongside the separate data socket, but that is a different arrangement from using USB4 for charging or a display. Count the roles that remain available together rather than adding every advertised function into one fictional port map.
Both card slots can work together
Satechi explicitly says the SD and microSD readers can be used simultaneously. Both are described as UHS-I, with a listed ceiling up to 104 MB/s and support for the documented card types up to 2 TB. This is stronger evidence for a two-card workflow than simply seeing two slots in a photograph.
Actual copying still depends on the cards, files and shared host connection. The card-reader specification should not become a claim that every card reaches the listed maximum, particularly while other storage is busy.
Charging is a supported role, not a supplied charger
The USB4 pass-through connection is described as supporting charging up to 100 W. The package lists the hub and guide rather than an external charger. Check the appropriate power source and the computer’s requirements; the separate 10 Gbps USB-C data socket does not support charging pass-through.
The maker also excludes iPad charging from the USB-A data ports. Shortlist the Pro Hub Slim for its documented MacBook fit, one-screen route, fast data mix and simultaneous card access. Choose another arrangement when two-screen behavior for your exact Mac, a supplied power kit or independent downstream USB-C roles is the deciding requirement.
Satechi’s exact Pro Hub Slim page and the linked original quick guide establish the roles and computer restrictions discussed here.

| USB-A downstream data ports | 2 |
|---|---|
| USB-C downstream data ports | 2 |
| HDMI outputs | 1 |
| Full-size DisplayPort outputs | 0 |
| USB-C video outputs | 1 |
| Full-size SD slots | 1 |

| Simultaneous card slots | Yes |
| Power adapter included | No |
| Host requirements | Two adjacent USB-C host plugs fit a named MacBook configuration. Check side-port spacing and case clearance. |
| Screen arrangement | HDMI is advertised up to 4K 60 Hz, and USB4 video up to 6K 60 Hz separately. Base M1/M2 are limited to one external display; M3 dual extended displays require the lid closed. A uniform dual-screen timing is not established. |
| Power and charging | The full-function USB4 connection supports charging; the separate USB-C data socket does not. An external charger is not included. No guaranteed delivered-host wattage is certified here. |
| Data and device limits | Two USB-A data sockets and one separate USB-C data socket are advertised at 10 Gbps. USB4 supports a separate 40 Gbps data role, but that same socket cannot simultaneously be counted as an independent charger input and another direct data connection. The USB4 40 Gbps link headline does not certify an ordinary USB 3.x data rate for that socket. |
| Installation | Silver ST-HUCPHSS is explicitly listed alongside space-gray and midnight color codes. Both SD and microSD readers support simultaneous use at their advertised UHS-I capability. |
