Anonymous: I'm not sure what you're trying to do for your science fair project but this sounds like a hard way to get DC voltage. Coiling a black and red wire around the charger isn't going to work. You could maybe feed 150-300V DC into the charger instead of AC (since the AC gets converted to DC internally), but that's dangerous voltage to be messing around with. The inverter would be an easy and relatively safe approach. Or you could get a car adapter charger and feed it 12V, which would be another easy approach.
