Reply to comment by TehWildMan_ in ELI5 North American USB power in Europe by historyguy2

So USB has its own voltage and the 120/230 v doesn’t matter so much with USB?

Yes, the USB cable is carrying 5 (or 9/12/15/20) volts direct current. Thr job of the charging brick plugged between the USB cable and the wall is to regulate AC power down to direct current for USB
