I didn't have much time to give this new Optimus Prime a proper look over, but it's pretty rad as far as I can see. I like that he's not sporting traditional Optimus colors. I sort of don't understand the full scope of the gimmick since in my haste I forgot to take a picture of the back of the box.
Best I can tell the USB plug is to charge the "Allspark" cube, and that powers the figures lights, sounds, and phrases. Although the box has it associated with the recent film, "Transformers: The Last Knight", it doesn't have anything to do with it. The figure itself looks nothing like how Optimus did in the movie. Still though, I may pick this up in the future out of curiosity.
