Dual-slot operation with 5 Gbps transfer

Two card slots can be read at the same time, removing the need to swap cards repeatedly. The USB 3.0 interface delivers up to 5 Gbps and remains compatible with USB 2.0 and USB 1.1 hosts. Power is drawn directly from the host port with no external supply needed.

Beige finish and broad OS support

The beige housing matches light-coloured setups and adds no software overhead. Compatibility spans Windows 10, 7 and XP, Mac OS, Linux and Android devices such as MacBook Pro, MacBook Air, iPad Pro and Galaxy S21. The plug-and-play design means files are accessible the moment the adapter is connected.

Questions about this item

How do I connect the reader to a USB-C phone and which slot do I use first?

Insert the USB-C plug into the phone's port, then insert an SD or microSD card into the matching slot; the reader works immediately with no driver installation.

Will the card slots wear out or need cleaning after heavy use?

The spring-loaded slots are rated for thousands of insertions; occasional compressed-air cleaning keeps contacts reliable.

What limits transfer speed when I copy large video files continuously?

The USB 3.0 interface caps the link at 5 Gbps, so sustained throughput cannot exceed that ceiling.
