    the non grounded plugs are usually only used on double isolated devices, like your phone charger.

    double isolated basically means all the outputs are only referenced to each other and not to ground, so you won’t get a shock by touching a usb plug, where you absolutely would if you touched live wire, where the reference is earth

      my pc case shocked me when I touched it, not a huge shock like live wires but enough for you to feel a little pain (like static shock on winter day). My phone charger also shocked me the same way when i touched the metal part of the USB head.
