Clip-shaped 9-in-1 USB-C Hub

The TOPWOLF SS-ST901A is a clip-shaped USB-C docking station that expands a single USB-C port into nine connections. It adds a 4K@60Hz HDMI output, Gigabit Ethernet, three USB 3.0 ports, SD and TF card slots, a USB-C PD charging port, and a 3.5 mm audio jack. The gray hub folds for storage and rotates 360 degrees for flexible positioning. It works with Windows, macOS and Linux devices that have a USB 3.1 Type-C interface.

For mobile users needing one video port

This hub suits iPad Pro, MacBook, notebook, tablet and phone owners who want a compact, foldable adapter for a single 4K display, wired internet, peripherals, card access and audio while charging through USB-C PD. It is not for buyers who need more than one video output, who require video bandwidth beyond 4K@60Hz, or who need a stationary dock with a fixed stand and cable management.

Single 4K@60Hz HDMI output decides fit

The defining specification is the single HDMI port limited to 4K resolution at 60 Hz. If your workflow demands dual monitors, higher refresh rates at 4K, or a different video interface, this hub will not meet that requirement.

Questions about this item

How do I attach the clip-shaped hub to my 12.9 inch iPad Pro?

Align the clip over the iPad's USB-C edge, press firmly until it clicks, then rotate the 360° hinge to your viewing angle; the step users miss is seating the clip fully before rotating.

Will the SD and TF card slots or the 3.5 mm audio jack wear out and need replacement?

The slots and jack are solid-state with no moving mechanism; only the folding hinge sees repeated motion, so under normal use no component requires scheduled replacement.

What limits 4K 60 Hz output when I keep HDMI, Ethernet and three USB 3.0 drives active for hours?

Sustained 4K 60 Hz, Gigabit Ethernet and 5 Gbps USB 3.0 traffic share the single USB 3.1 Type-C uplink, so total bandwidth is the first bottleneck under heavy load.
