    Even in the early 00s it was already hard to grasp for some folks. I had friends who called me a liar for claiming that I could charge my mp3 music player by slotting it in the USB port of my tower as opposed to swapping out AAA batteries

        I’m not sure about the timeline on portable mp3 player development and popularity, but this was 2002 or 2003 and I was the only one in my friend group who had one with a li-ion battery as opposed to AAA-batteries.

        “USB doesn’t deliver power, it’s for file transfer!” I was told. Some of my friends were also really stupid, though. That could have contributed to this wonder of technology.
