Thread: Portable jump starters, any good

we have jump packs at work....about size of kids school bag...12 or 24 volts we start large trucks with them ,utes n cars piece of piss....small 5-10hp motors no worries...the buzzer alarm if hooked up wrong is AWESOME.... it clicks if not connected well enough too.
small led picture screen even better for techtards...tells you whats wrong if you have done it wrong....
