How do car alternators work? Answered
I am working on way to charge electronics at long festivals. There is no electricity and then my camera dies. My solution is to bring a car battery and charge USB devices using car power/usb power adapter.
My questions is about charging car batteries. I noticed that the highest charge setting on my wall-power car charger is 6 amps. A car alternator on the other hand supplies 65 amps. Why such a huge difference? When you jump start dead car battery and then charge the battery with the car running the alternator is the battery really charging at 65 amps? That is 10 times more current than from a wall charger.
