I’ve been asking this question for a couple of years, and a few times even got ready to pull the trigger on a buy. I start reading the reviews, and they all have problems. This includes the antigravity brand, which from the reviews I’ve read, may be the best but watch for counterfeits. They all have the high temp problems, and the low temp problem. Overcharge problem, undercharge problem. They tend to die after a couple years. The real problem is you can’t keep them safely in your vehicle, which is the whole point of having the paperback book small size.
I’ve come to this conclusion:
The Best one is NONE of them. Get the super capacitor type. This design appears to solve all the problems, including the long-life problem.
Right now the prices are a bit high, not prohibitively so, but high. I think I can stick with my old lead-acid jumper for a little while longer till the prices comes down.
