Charging the car battery and jump starting are two different things. If you tried to jump start through the lighter (or aux power in my car), that 15 amp fuse would blow immediately.
It'd be like trying to jump start the car with a 10-15 amp trickle changer. But something like that would be useful for a hybrid, like my Insight, where if the 12-volt battery goes dead, you can't get power from the IMA battery.
