Had to jump my daughters car today, and was thinking maybe a portable jump starter might be more handy than jumper cables. The up side would be not having to worry about damaging the electrical system on the vehicle supplying the power (or possibly both vehicles) if using jumper cables. So far, I have never had a problem, but it does cross my mind once in awhile. Especially with the complicated electrical systems on the newer vehicles.
What is the consensus, anybody have one and if so, are you happy with it?
Short answer, great to have. But... be sure it's adequately sized, and not used on something with a very heavy draw. Friend melted the cables off his trying to jump a diesel with twin DEAD (bad) batteries.
We've had everything from the small pocket sized deal to a truck cross box sized deal. For heavy trucks, I use the big box all day. For passenger cars, We've used the pocket size until we melted it trying to work on a medium sized diesel. For the most part, we use the small carry boxes.
I have used them and they work. I left my headlights on in my '69 1/2 ton for 8 hours. I hooked up the magic box and left it on for about 5 minutes I guess and it started! I have found that you need to leave them on for a while before you try to start the engine. They are kind of like chiropractic care and acupuncture. Don't ask how they work. They just do. Carl
some small portable generators feature a battery charging capability (and cables for it). This Yamaha 2KW portable can charge 12V at 8 amps. Maybe not great for a quick jump start, but still a pretty cool feature.

I don't recall the part number. I don't have it any longer. The battery was so dead that the headlights would not shine. I drove home once it started (30 minutes) and shut it off, then started it right back up.Work fine, last long time.
I got a small cheap one from NAPA that's adequate for boosting a Corolla, a RAV, and even a Chevy V6. About 9" long, 3" wide, and 7 or 8" high. For a truck - a bigger and heavier one, weight-wise and amp-wise, with a lot more oomph.
BTW, don't try and boost a completely dead battery, you're askin for trouble. Leave a charger or booster pack on it for half an hour or so, then check it with a meter. If it shows even a little its OK to boost. If it still shows "0" the battery's toast just like a frozen one, so chuck it....uh....I mean take it to the recyclers.
I sure like tc's idea so I'll check the prices.
