I don't know what SmallRig was thinking when they posted this. This does not work on Pocket 4K or 6K. I ordered one and replaced it thinking it might be defective, but after some testing with various cameras (mine and a few of my buddies) and various T5 and Juggler drives, the USB-C port on this thing isn't working . Work. SmallRig needs to go back to the drawing board with this one. It was the intention, but implementation suffered a major setback.
