4.0 out of 5 stars
good idea not supported by technology, August 24, 2005
This review is from: Coleman PMJ8960 10 Amp/Hour Jumpstart System With Work Light (Tools & Home Improvement)
This is a great idea - a portable jump starter. Unfortunately, current-day battery technology doesn't make it very practical. If, like me, you live in an area where you get cold weather your car is either sitting in cold temperatures or in the blazing sun. Neither condition is conducive to long battery life, so the Powermate is not likely to be fully charged for long if left where it makes the most sense - in your car. Mine spends most of its time in the house where it's only useful for those rare times when the car's battery has died in my driveway. Ideally, it needs some kind of system to keep itself fully charged while sitting in the car - you can hook it up to your car's cigarette lighter to charge it but I do not get the impression from the instructions that this is a recommended procedure - it's just not designed to be kept connected to a charging system 24/7. Power and battery management is expensive and Coleman left it out of this product. If you're thinking this will make you a self-contained AAA service, probably not. After long exposure to temperature extremes in your car you'll likely find yourself stranded with both a dead car battery and a discharged jump starter and you'll need a tow truck anyway. All told, this is a good idea that's poorly executed. It needs to be kept at home and in the house to be fully charged and to keep the charge well enough to be of any use. There are other jump starters of a similar idea that run on D-cell batteries. Possibly a better idea - at least you'd be more likely to breakdown near a convenience store where you could buy a few packs of fresh batteries - when this thing is dead, so are you - right in your tracks. If your battery is dead you can't charge this thing up from a dead car battery. It seemed like a good idea when I bought it - now I realize it was a waste of money - it's just not functional in the "real" world.

Agree w/ other reviewer -- good idea, but this one's a waste of money!, June 23, 2006
This review is from: Coleman PMJ8960 10 Amp/Hour Jumpstart System With Work Light (Tools & Home Improvement)
I agree with the other reviewer, but I'm angrier about having wasted my money on this product! In the 2 years that this product actually worked, just like the other person said, it was constantly losing its charge in the extreme heat and cold conditions that you find in the trunk of a normal car (particularly if you do not have your own garage...). I was able to use it successfully just ONCE. Of the other two times I needed to use it, one time it couldn't do the jump because it wasn't fully charged, and the other time it couldn't do the jump because it wasn't fully charged *and* I accidentally left the radio on when I tried to do the jump. (Warning: if you do use this product, make *absoutely* sure that *everything* electrical in the car is turned off before trying to jumpstart your car, otherwise the wipers, heater/AC, radio, lights or whatever will drain too much juice and you will not be able to jumpstart your car.) Now, 2 years later, the product won't hold a charge at all and I have just had to dump it in the trash. It is a good-sized chunk of plastic, metal etc. and it seems a terrible waste not to be able to recycle or reuse it somehow. I just complained to Coleman and they said it was a licensed product and they took no responsibility for it and referred me to the actual mfr, Team Products International. When I complained to them, they sent back a form email saying it was under 2 year warranty and that was it. I am totally disgusted with this. Bottom line, in my opinion towing insurance from your auto insurance co. or roadside assistance from your cellphone co. would be money better spent. And of course it's a good idea to carry regular (LONG) jumper cables, a blanket, etc. in case of wintertime emergency.
