From Pathfinder Wiki
Making fire from an electric spark can be dangerous and should only be used in an emergency. You will need to set up some tinder ahead of time and then prepare to throw an electrical spark. This can be done with jumper cables from an automobile by connecting one end of the terminals to the battery, and then quickly touch the other ends together next to the tinder. Do not hold the terminals together for more than an instant or you will drain the battery.
