Compact 5-in-1 USB-C hub for MacBook

The LUOM PB-9577 adds two USB 3.0 Type-A ports, an SD card slot and a microSD card slot through a single USB-C connection. It suits MacBook Pro 13-inch and 15-inch models from 2016 through 2018 as well as other USB-C laptops running Windows, macOS, Linux or Chrome OS. The aluminium body matches the Space Gray finish of those notebooks.

Pass-through charging up to 87 W

A Thunderbolt 3 port delivers up to 87 W Power Delivery at 20 V and 3 A while the hub is in use, so the host laptop charges during data transfers. The two USB 3.0 ports operate at 5 Gb/s, and each card slot reaches up to 104 MB/s. No fan or active cooling is required, keeping operation silent.

Travel pouch protects the aluminium shell

A supplied carry pouch prevents scratches when the hub is slipped into a pocket or bag alongside the MacBook. The package contains no software or drivers; all functions are plug-and-play across the supported operating systems. Memory cards are not included.

Questions about this item

How do I connect the LUOM PB-9577 hub to my MacBook and what step is often missed?

Plug the USB-C male connector directly into the MacBook's USB-C port; the step often missed is ensuring the host port supports Thunderbolt 3 and 87W Power Delivery so charging works while data transfers.

What maintenance or replacement will the LUOM PB-9577 need over time?

The aluminium casing and fixed cable require no scheduled maintenance; if the USB-C plug or the Thunderbolt 3 port wears out from repeated insertion, the whole hub must be replaced.

What limit appears first when I keep all ports busy on the LUOM PB-9577?

The Thunderbolt 3 port caps Power Delivery at 87W, so sustained high-power charging alongside two USB 3.0 devices and both card slots will hit that 87W ceiling first.
