As a general rule how often do jump starters need to be recharged especially the small ones that just jump start?

So would have to compensate to compare to 12v. Point is a tiny battery today can start a large diesel engine no problem.
Do those things actually work?

Customer hooked up his little jump box thing and it did nothing, just made a little clicking noise and whined a bit....
