 I bought one of the lithium  emergency power jump starter battery.
Those things amaze me.  Got one off Tumu for about $ 25 and unhooked the
battery on my Toyota 4 cylinder truck.  It started the truck 3 times and
I quit at that .  It may have started it even more.  For my truck and
car I did buy a better one off Amazon for around $ 50 or maybe more.
Have not had to use them yet. The better ones will not send out any
power if the car battery voltage is below about 10 volts or you try to
hook it up reversed.  There is an over ride button that will send out
power to a totally dead battery or probably evenif hoked in reverse.
The cheap ones do not have this feature.
They even have phone charging sockes.

Those features are nice, but why would a normal person buy it?
I made myself a pair of jump start cables from cables that were surplus from a telephone exchange. Very good cables, thick. That would be 1999. I carry them in my car, but I don't remember having ever used them. Maybe once?
A nice kit like you describe would probably have the battery die of old age in that time. For a garage or parking lot to have, yes, but a normal person?
