288 amps x 13v = 3744 watts to start a small car

I seriously doubt a 6 amp hour battery will put out 3744 watts worth of energy, that would equal 37 minutes of a 100w drain (3744 divided by 100)

I may well be missing some figures in my simple math above so if you know why this jump starter stores more power then I have denoted please post your math or hypothesis.
