That is micro-USB 3.0 and it’s an annoying connector that now is just as obsolete as micro-USB 2.0 and for some reason, around 2014, sone smartphone manufacturers thought it was a good idea adding it on their phones. Didn’t last long and got replaced by normal micro-USB again (which is much worse than lightning imo).
That is for external hard drives, the same ones that plug into Macs…

My Samsung S5 had one of those. You could just put a normal micro USB cable in them to charge.
