I have a nice stereo and i want to be able to turn my car off and run the stereo for a long time. The battery dies after about 30 minutes so i wanted a way to plug the car accessory into a household outlet. The car draws about 960watts. Thats 60amps on a 12Vdc. Some ideas i had were… 1: plug the 120Vac into the alternator that then converts the alternating current into direct current. 2: put a computer power supply in my car that has a 60amp 12Vdc rail. 3: Buy a very expensive (i cant actually afford it) 12Vdc power supply. 4: use a jump start system that can be plugged into the house outlet and the car at the same time. (would that draw the power off the house?)
