Why aren’t car batteries smaller?

140 viewsEngineeringOther

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?

If I understand it right, those external power packs can go “UP TO” the said amount. but that is not the standard power output. Sometimes those power packs can only keep that level of power ina few seconds since they power other smaller things like smartphones.
