Purpose-built 7-in-1 Type-C dock

The Silicon Power Boost SU20 adds seven ports through one USB 3.2 Gen 1 Type-C connection. It supplies HDMI video, three USB Type-A sockets, a USB-C power-delivery port, plus SD and microSD card readers. The aluminium housing keeps the unit light and helps dissipate heat during extended use.

Suits thin laptops lacking legacy ports

Users who need simultaneous monitor output, multiple USB peripherals and card-reader access from a single Type-C socket will benefit. Buyers whose devices only offer USB 2.0 or lack DisplayPort Alt Mode cannot use the video or 5 Gbps data features. Systems requiring more than 60 W charging should look at higher-power alternatives.

Bundled connectivity expands workflow

The HDMI port drives an external display at 3840x2160 resolution at 30 Hz. Three USB 3.2 Gen 1 Type-A ports and one USB-C PD port allow keyboards, mice, drives and other accessories to run together. SD and microSD slots operate concurrently for direct media ingest. Passthrough charging up to 60 W keeps the host powered while all ports are active.

Questions about this item

Does my laptop need a USB-C port that carries video and data to use the HDMI output on the Boost SU20?

Yes, the single USB-C input must support DisplayPort Alternate Mode so the dock can drive the HDMI port at up to 3840x2160 @ 30Hz.

Can I keep using my older USB 2.0 flash drives and mice with the three Type-A ports on this dock?

The three USB 3.2 Gen 1 Type-A ports are backward compatible, so USB 2.0 devices will work at their native speed while newer drives can reach 5 Gbps.

How do I confirm the 60 W pass-through charging is actually reaching my laptop after I connect everything?

Check your laptop’s battery icon — it should show “plugged in” or the charging indicator, and the dock’s aluminum housing will feel slightly warm as it delivers up to 60 W.
