Our take
Choose ST-UCPHMXS for a compatible MacBook when its two-port fit and collection of USB4, HDMI, Ethernet, card, data, and audio connections fit the desk setup. Confirm the USB4 power/display revision before relying on its maximum.
A MacBook user with two unobstructed adjacent USB-C ports who wants wired networking, display, card, data, and audio connections and can verify the power-document conflict..
It is not suitable for computers without two adjacent unobstructed USB-C ports, a requirement for USB-A charging, or a purchase that depends on resolving the conflicting USB4 power and display figures without checking the current documentation.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- Satechi identifies the silver model and shows its two-plug connection and port roles.
- USB4 data up to 40Gbps and separate HDMI up to 4K/60Hz are listed, with simultaneous display use described.
- Gigabit Ethernet, SD/microSD, USB-A and USB-C data, and adjustable audio are included in the documented layout.
What to weigh up
- Two adjacent laptop USB-C ports are required for the physical fit.
- The manual and quick-start guide conflict on USB4 power and display maxima.
- The USB-A port is limited to 900mA and is not for charging; historical Amazon mapping is unverified.

Full review: how the features affect your choice
What the features mean for you
Confirm the laptop's two-port fit before buying
This is a MacBook-specific style of hub that attaches through two neighboring USB-C connectors rather than a loose single host cable. That can keep the unit close to the computer and make its audio connector arm line up with the headphone jack, but it requires the intended ports to be side by side and unobstructed. Check the exact MacBook generation, case thickness, and port spacing against the current product manual. A laptop with a single USB-C host port will not fit this connector arrangement as described.
The USB4 output does more than ordinary hub data
Satechi describes the USB4 port as supporting data, pass-through power, and external display output. Both official sources list up to 40Gbps data, but the manual and quick-start guide disagree: one gives 96W and 6K/60Hz, the other 100W and 5K/60Hz. Use the current seller documentation for the exact version rather than assuming either maximum. The separate HDMI port is listed up to 4K/60Hz, and the manufacturer says USB4 plus HDMI can run at once; the computer and monitors must support the chosen modes.
Keep the USB data ports distinct from charging
The manual describes one USB-A data port and one USB-C data port, each up to 5Gbps, while its USB-A limit is 900mA and it does not support charging or Apple SuperDrive. That makes the hub useful for low-power peripherals and data accessories, but it is not a substitute for a USB charging station. For storage, check the host, cable, and shared-bandwidth conditions; the source does not claim independent 5Gbps throughput for all functions at the same time.
Wired networking, cards, and audio round out the MacBook setup
The additional ports include Gigabit Ethernet, SD and microSD card readers, and a 3.5mm audio connection whose arm can be adjusted to the laptop's thickness. This makes the model more workstation-oriented than a basic four-port data expander. Buyers should compare the card types, wired network requirement, and headphone connection they need with the physical diagram. The historical ASIN is not verified on an Amazon page, so use the tagged model search and confirm the silver suffix ST-UCPHMXS.
Separate HDMI from the conflicting USB4 display figures
The listed HDMI mode is up to 4K/60Hz, while the two Satechi documents disagree about the USB4 port's maximum display mode. Treat those as separate outputs when matching a monitor: the guide and manual both describe HDMI, but only their USB4 display figures conflict. The manufacturer also describes USB4 and HDMI working simultaneously, so check the laptop's own display capability and the current revision's instructions if you need two screens. The historical Amazon page did not load, making the silver model code and official documentation important checks on a current result.
Check how the adjustable audio arm meets the laptop
The manual shows a 3.5mm audio connection on an adjustable arm, alongside the two USB-C host plugs. That can help position the jack for a compatible MacBook thickness, but the same physical-fit requirement applies: both adjacent host ports must be available and unobstructed. The saved documents identify the audio connector and adjustable arm, but do not describe detailed microphone, headset-control, or audio behavior. If a particular headset feature is essential, confirm it with the current model documentation rather than assuming that a 3.5mm socket supports every control. This physical check is separate from the display and power question: it helps determine whether the hub can sit correctly on the laptop, not which USB4 maximum is authoritative.
