6-in-1 SD Card Reader USB Type-C/A/MicroUSB Compatible This is a multi-card reader that supports six types of connections: USB 2.0, USB 3.0, Type-C, Micro USB, SD card, and microSD card, all in one device. You can easily read and write SD cards and microSD cards not only on your computer but also on Android smartphones and tablets that support the OTG function. It has a convenient structure where a Micro USB terminal appears when you flip up the USB Type-A terminal, allowing you to carry all six terminals compactly. I purchased it from an overseas website, but it was different from what I wanted, so I have never used it. I have not checked the operation either.
