12 minutes is still a very short charge time.

and EMT, there is a slight error in your calculations. Considering that V in the us is 110, then 1000watts would take 9.09 amperes.

Most house sockets are wired to a 15 amp circuit, which will give you 1650 watts, some are wired 20amps with a special socket which will give 2200 watts.

And you are talking about a capacitor, not a battery. Capacitors can charge as fast as the current is given to them. and most laptop baterries are around 30a/hrs I believe? maybe less? im not sure. so if you are figuring 12 volts at 30 a/hrs, that is 360 watt/hrs of electricity, and if the charge can do 1000 hours, if not more, then it sholud be able to charge in 360/1000=.36 hours = 21.6 minutes.

I am pretty damn sure that my figures are off, because it should be much quicker than that. I'm too tired. capacitors should be able to charge very wuickle. anyway, om to tires to typw anymore.
