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).

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

It's for devices that require more power usually, many external harddrive/ssd cases still use them.

Yea, and since usb-c there’s no reason why. Micro b 3 is worse in every way
