If all you're planning to do is drive on and off a trailer at a car show, that PowerGen alternator might be a good choice. Don't count on it to do a good job of keeping the battery charged or lasting a long time in a daily driver situation. The physical shape of a generator-looking alternator is all wrong for doing a good job of battery charging and/or powering high current draw accessories.

Friends of mine who have been drawn into (I could have said tricked into) buying this tell me: (a) they don't cool well at all so (b) in a few months they burn up and leave you stranded and (c) they're incredibly overpriced. In the process of burning up they sound like a you-rent-it cement mixer. Aside from that, they're just fine. Yet another product that was underthought, undertested and overmarketed. Pertronix as a make-believe alternator.
