Our take
The gold Satechi ST-CMBPG attaches to two adjacent MacBook USB-C ports and adds HDMI, USB data, Thunderbolt pass-through and SD/MicroSD readers. Its charging documents conflict and the old Amazon ASIN is unmapped.
A MacBook owner with two adjacent USB-C/Thunderbolt ports who wants an attached hub and can verify case clearance..
A computer with one USB-C port, a case that blocks the plugs, 4K/60Hz HDMI, or a buyer needing a single confirmed charging ceiling.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- KTC identifies the gold ST-CMBPG model.
- The manual describes HDMI, USB-A, USB-C data, Thunderbolt and card readers.
- A direct-attach layout can reduce cable clutter on a compatible MacBook.
What to weigh up
- Two suitably placed host ports are required and a case may obstruct the fit.
- HDMI is listed only up to 4K/30Hz.
- Manufacturer guides differ on pass-through power; B07KRQ6BCB is not mapped.

Full review: how the features affect your choice
What the features mean for you
Check two-port spacing and case clearance first
The ST-CMBPG is a direct-attach hub made for compatible MacBook Pro and Air models with two neighboring USB-C or Thunderbolt ports. Its two plugs can keep the hub close to the computer, but that same shape limits where it fits. A laptop with only one port, different spacing or a protective case around the edge may not accept the attachment cleanly. Compare the exact computer generation and case with the manufacturer's compatibility notes before choosing this form instead of a cabled hub.
Set the HDMI expectation at 4K/30Hz
Satechi's user manual lists the HDMI output up to 4K at 30Hz. That can suit ordinary office display use but does not meet a 4K/60Hz requirement through the HDMI socket. The manual also describes a separate Thunderbolt path, but that should not be counted as another HDMI port or assumed to work in every display arrangement. Check the Mac model, monitor and intended resolution and refresh together. The 4K/30Hz value comes from the manual, not a test of this unit.
Keep the USB-C data port separate from charging and video
The documented arrangement includes two USB-A 3.0 data ports and a separate USB-C data-only socket. Satechi says that the USB-C data port does not charge a computer or send video; the Thunderbolt connection has a different role. This matters when choosing where to attach an SSD or charger. The listing also includes card readers, so its advertised function count mixes several connector roles rather than providing a bank of interchangeable USB-C ports. Check the manual's port labels before planning a desk layout.
Use the card slots for SD and MicroSD workflows
Satechi's manual lists both SD and MicroSD slots. That is useful for a MacBook user who imports files from either card format without carrying a separate reader. The cited documents do not establish a card speed or promise a particular camera workflow, so avoid treating the presence of two slots as a performance rating. Check the cards and transfer needs that matter to you, and distinguish those reader connections from the hub's USB data ports. The stored model review does not claim hands-on transfer testing.
Resolve the 60W versus 87W charging difference
The Satechi user manual describes up to 60W pass-through charging, while the getting-started guide gives up to 87W. The available manufacturer documentation does not settle which ceiling applies across revisions or configurations. It would be misleading to select one number as the universal laptop output. Confirm the exact gold model, current instructions and charger path if the computer's power requirement is a hard condition. This entry leaves numeric charging capacity unresolved and does not use the conflicting values to rank the hub.
Search by ST-CMBPG rather than relying on the old ASIN
KTC identifies the gold ST-CMBPG model, while Satechi's manual documents the Type-C Pro Hub layout. The historical Amazon detail page for B07KRQ6BCB was unreadable and no saved source maps that ASIN to the gold model. Keep ST-CMBPG distinct from the space-gray ST-CMBPM with a different suffix. Use the tagged model search and compare the finish, model code and two-plug panel on the selected offer. This review does not claim current price, availability or a verified Amazon listing.
Check the separate Thunderbolt path before adding another display
The manual describes a Thunderbolt 3 pass-through connection in addition to HDMI and a USB-C data-only port. These sockets have different roles: the USB-C data connection is not a display output, and the Thunderbolt path depends on the host and attached device. If you plan to use the hub for more than one display connection, verify the exact Mac model and the manufacturer's supported arrangement rather than treating both connections as interchangeable video ports. This keeps the hub's compact port map distinct from a general desktop dock.
