I think I'm going to run 50 volts through all my usb cables when I get home.

  Sounds like a great way to fry your lightning and usb-c cables as the former has a mfi chip, and the latter has a pull down resistor.

    I guess the secure solution is to carry around your own X-Ray verified lightning-USB dongle and high voltage fry any dumb cable you find yourself needing.

      Or always buy two and dissect one.

  And why 50? That's so arbitrary. Why not 120? Or 240? Or 9?

    (IANAEE) 120 and 240 are a bit more painful when mistakes happen. And 9 seems too low (normal USB voltage is 5, so 9 might be within safety margins).

      My phone charges at 9v over USB-C so I would imagine it would be just fine.

      It's probably just his DC power supply he has handy. As far as 120/240 thing, if you have a component not meant for that kind of voltage, it might fail open, or it might fail short. If it fails short, high amounts of current might be allowed to flow through other components which would carbonize so even more current would flow. And maybe catch fire.

        Excellent points. Thanks!

      "120 and 240 are a bit more painful when mistakes happen" ... aaah. That sounds like the voice of experience. Man, I love the internet.
