USB-C 3-in-1 Card Reader with USB 3.0 Port

This compact adapter lets laptop and tablet users read SD and microSD cards while adding a USB-A port for peripherals. It suits photographers, students and mobile professionals who need quick access to media files on devices that lack built-in card slots.

5 Gbps transfer speed over USB 3.0 and USB-C

Both the card reader and the extra USB-A port operate at up to 5 Gbps, so large photo and video libraries move quickly between card, computer and external storage. The single bandwidth figure determines whether the adapter keeps pace with your workflow.

Passive design runs silently without extra power

The unit draws all power from the host USB-C port, adding no fan noise or measurable heat during normal file transfers. It stays cool to the touch even during extended copy sessions.

Questions about this item

What does the 5 Gbps transfer speed mean when I copy files to my laptop?

The USB 3.0 and Type-C ports each support up to 5 Gbps, so large photo or video batches move at the full bus rate instead of bottlenecking at USB 2.0 speeds.

How does the USB 3.0 Type-A port limit what I can plug in?

The female USB-A port is a USB 3.0 connection, so flash drives, mice, keyboards or wireless receivers run at up to 5 Gbps; slower devices simply fall back to their own maximum.

What physical space does the adapter need beside my device’s port?

The reader plugs directly into a USB-C socket and adds a short stub with SD and microSD slots plus a USB-A socket, so it sits flush without a cable or extra clearance.
