Yes no problem

The PowerGuard Mini USB-C MicroSD Adapter works with devices that have USB-C and Mass Storage Device support, which includes most modern Android devices, including those running Android 10. It requires no additional drivers and shows up as a standard 'Mass Storage' device under the operating system.

The SD card appears in the "Files" app. (at least this is the case on the iPad)

I use this adapter... it is certainly 3.x (but unsure what version); and can handle my 512 GB cards

Yes, if you have an iPad with a USB-C port.
