I am researching portable jump starters and find a wide variety of current they provide to the dead battery. Currents range from 500A to 3000A plus. Manufacturers rate them for ICE engines, such at 6 liters gas or 5 liters Diesel. Since an EV only has to worry about the battery itself and not the size of an engine, what is enough current to get an EV6 going? There are some other features you get as you go up in amps but the glaring one is the price of the unit. Would 1000A be a good amount?
