I've recently bought an air compressor with a cigarette lighter socket cord. It plugs into your car.
The specs say that it takes 12V dc at 14A but I want to power it with small batteries (AA, AAA, 9V) so I can carry it on the go. I know that there are heavy car batteries that would work, but I want a light solution.
I tried using 2AA's and a 9V, only to realise that the current was too low.
Without putting 105 batteries in parallel, is there any way to amp up the current of a battery?
