Our take
Consider the ST-TCMPHM when a compatible USB-C tablet setup needs a small combination of HDMI, wired audio, one USB connection, and a charging path. The guide gives a specific use case rather than describing a general desk dock. Its limits are equally specific: 30Hz HDMI, no case clearance, a restricted USB-port use description, and no verified wattage for the row's charging claim.
A compatible USB-C tablet or mobile-device owner who can use a case-free connection, one photo-transfer USB port, 30Hz HDMI, and an unverified PD wattage..
It is not a good fit for a case-covered tablet, several general-purpose USB peripherals, a required 4K/60Hz display mode, or a charging setup that needs a confirmed wattage.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- Satechi identifies ST-TCMPHM in its official documentation and describes its port layout.
- The guide lists HDMI, one USB 3.0 port, a USB-C PD input, and a 3.5mm audio jack.
- The maker provides a concrete iPad example and explains case and USB-use limits.
What to weigh up
- The guide lists HDMI at 30Hz rather than confirming the row title's broader display implication.
- Satechi says the hub is not compatible with cases and narrows the USB port guidance to photographic-device transfer.
- The row's 60W/3A wording and current Amazon offer are not confirmed by the saved sources.

Full review: how the features affect your choice
What the features mean for you
Does this port mix fit a mobile setup?
Satechi's quick-start guide describes a Type-C Mobile Pro Hub with HDMI, one USB 3.0 port, a USB-C PD connection, and a 3.5mm headphone jack. This is a small, selective arrangement for someone who wants a wired screen and audio plus one additional connection from a USB-C tablet or mobile device. It does not replace a multiport desktop dock with several USB sockets, network access, and card readers. The guide uses a 2018 iPad Pro as an example, so verify the exact host model and its capabilities before relying on that example as compatibility for another device. The connector shape alone does not prove that every USB-C host can drive HDMI or charge through this adapter.
How should I read the 30Hz HDMI listing?
The guide specifies HDMI at 30Hz. That limit matters for a buyer who plans to use a monitor for long desktop sessions, video, or fast-moving content, because a title that mentions 4K does not guarantee a 60Hz mode. Confirm the display resolution and refresh combination supported by both the hub and the host, especially when the tablet's USB-C video support is not documented for the selected setup. The sources do not establish a 4K/60Hz capability or multiple-display operation. Choose this adapter only when its published mode is acceptable, and compare an alternative with a verified output table if a higher refresh rate is a hard requirement.
Will the hub work with a tablet case and ordinary USB devices?
Satechi says the adapter is not compatible with cases, so a protective shell can prevent the hub from seating correctly. Measure the connector clearance or remove the case when using it; do not assume that an opening around the tablet port will be enough. The same guide describes the USB 3.0 socket for photographic-device transfer and notes that it is not compatible with Apple SuperDrive. That is narrower guidance than a promise to support every external drive or accessory. Buyers who need general storage, a keyboard, and several other peripherals should confirm their exact workflow or choose a hub with a broader documented USB-use statement.
What does the PD connection establish?
The guide instructs the user to connect a USB-C charging cable to the PD port to charge the example iPad. It does not verify the historical title's 60W or 3A figure, identify a guaranteed wattage reaching the host, or describe how output changes while HDMI and USB are in use. Treat the port as a documented charging path, not a known power budget. If charging speed matters, check a model-specific specification for the input ceiling, required adapter, and host-delivered power. A separate hub power supply is not listed in the saved guide, and the PD input should not be confused with a downstream data port.
Is the current Amazon offer the same model?
Satechi's documentation index names ST-TCMPHM alongside ST-TCMPHS, and the guide describes the Type-C Mobile Pro Hub family. A reseller record pairs the historical B0BW28STRP clue with ST-TCMPHM, but the Amazon detail page was not readable in the saved research and the maker documentation does not establish a current exact offer. The affiliate link therefore searches by the model rather than claiming that the old ASIN is live. Compare the selected result's model code, HDMI mode, one-port USB layout, headphone jack, and connector shape with the guide. This review summarizes published material; it does not claim hands-on testing, buyer sentiment, price, or stock.
