I’ve been shopping around for an emergency jump starter to carry around in the car. I’ve found jump packs that are roughly a little larger than a cell phone, and produce 1000 amps or more. What is keeping them from being a main car battery?

You can crank your car with a normal battery like 50 to 100 times before it goes flat. The small emergency jump starters can crank a car from zero to five times depending on the size of the battery and the size of the engine.
