Ok, let's say I'm totally wrong in my original comment ... Devices do in fact accept current and chargers push current, or electricity or however you choose to say it. It's one way or the other ... no middle ground.
Most service drops into homes that are not "mansion" in size are usually 200 Amps or thereabouts. IF electricity is pushed, that would mean every device in your house or apartment is exposed to 200 Amps and 110 or 220 volts. You'd have some more pretty tough Macs there. Not talking about step-down transformers, or any other kind of intermediary devices, strictly the "draw/push" proposition.
Typically, appliances, to include Mac chargers (and we're still strictly talking "draw/push"), are NOT exposed to full 200 Amp service because it's not pushed, it's drawn. But if they were to have "full power" pushed onto them, and the voltage and phase matched, they'd be enormous! You'd have to have a forklift to move your charger around.
You guys can continue on if you wish, I got a MacBook to charge and I got to move the charger.
