Here's a cheaper one. BTW they are small enough to fit in your coat pocket.

I have an SLA based booster for each of my vehicles and, having already replaced two with worn out batteries, I'm tempted to give this a try. Being smaller makes it more convenient to share; but I'm a little suspicious of the current capacity of the jumper cable. Seems too small to carry 200-400 amps; even for the time it takes to start...I have one of these.
Just a little tip for those boosting other vehicles with your own or vice versa. When you connect the jumpers, make sure good vehicle is shut off. Attempt to start the dead vehicle. If it does not start, oh well. If you want to run the good vehicle for a while to charge the dead behicles battery somewhat, you run the risk of overworking your alternator. If you start the dead vehicle while good vehicle is running, now you are placing the demand of two vehicles on one alternator. Say goodbye to it and thank it for its service. Any time you start z vehicle on a dead battery, you will overwork the alternator.
First of all, I don't drive crappy vehicles. Secondly, why do you feel the need to belittle people? Does it make you feel better about yourself? Thirdly, having been an alternator and starter rebuilder for a number of years and over 37 years as an auto electrician, I think I may be a little more qualified than you to comment on alternator behaviour. Alternators are very well designed and built, but they are nor made to be battery chargers. When you max out an alternator, they overheat and diode and stator failure occcur. I have heard and seen countless stories about this very incident.What kind of crappy vehicles do you drive?
All mine have properly designed and built alternators that have survived that sort of direct abuse for years.
Well, I've been rebuilding and modifying them to custom applications for ~25 years and have no reason to feel that any decent properly made ones can't handle that sort of service work being I have personally seen many put in applications where they were running flat out non stop at 100% of their capacity, many putting out above their actual stock ratings too, for days at a time.having been an alternator and starter rebuilder for a number of years and over 37 years as an auto electrician, I think I may be a little more qualified than you to comment on alternator behaviour.
Disagreement does equate to belittling\bullying.
Playing the victim card is not a rebuttal.
