A:AnswerThis one got an android adapter, so can only use it to transfer files from the phone to the sd card. Then use the sd card to the computer. Hope I helped you with the info.
A:AnswerYou may need a converter I did I have a Galaxy j7 there's an app called video converter and it converted the video to the format that the Galaxy can read
A:AnswerIt will read any brand and/or class or SD cards. As for Galaxy S9+ phone, no, it won't work. S9+ has USB type C charging port, not Micro-USB. You need to look for the adapter with USB type C to connect to your phone. Insignia brand has one too.
A:AnswerYes But this version looks like its a micro usb. To upload you photos and videos to a computer you need a regular usb version, this one in the picture looks like a micro usb cable it would not fit into any laptop or desktop computer without an adapter.
