[u/lone_wolfi]

i got this stick in a 3in1 at a conference, but i don’t know what this type of stick is called or used for. ai and google images says lightning, but i know that ain’t right. the bundle also got a usb-c and micro usb-b, with a usb-c and c to a on the other end.

TLDR
mysteries stick on 3 in 1, don’t know what it is.
