Here’s the way: look at the little “crack” on the middle of the plug on one side (the vast vast vast majority have one) – that should be facing down. I haven’t used a vertical plug in a while but I think it faces left there.
For the forsaken anguish of God, microUSB, it’s reversed, so crack up.
This is flipping amazing. UX beats big corps hands down, recommendations are greatly innovative. One little thing: can we have a back button? It’s a bit clunky when I have to go to the top of my browser every time I go back from a post. Other than that, it looks great!
