Perry, I've been pondering doing that. Not to sound cheap, but I've been spending a ton of money lately, and I keep thinking two things. One is, this is a very compact little box. It was only $32 on sale. It'll get there, it'll get there. And besides I don't know whether the number of iron pieces I'll buy will warrant a further expense.
The second is, well, if I ever sell this huge house (which I will) and move to a smaller one (which I will) then yeah, space will be an issue, BUT the bigger charger on wheels wouldn't be THAT hard to store in a garage. Besides, it would make me give something else up that I don't use. And the little 10-amp ain't good for nothin much other than this. Maybe slow-charging my lawn tractor. Pfffft. Can't jump start my car with it. And if just one time more I haven't learned to manually shut off the lights because this car will NOT turn them off if you leave the keys in it (which I always do) then, just think. If I have a larger charger, I wouldn't have to wait up to 45 minutes for Triple A. And also, I figure it's quite possible I'll buy rustier iron as I go, because now I'm getting tired of eBay's shipping, and having much more fun rummaging in antique stores. So that all counts for something, right??? So in the long run, the saved shipping will pay for it. In fact, under some totally odd, weird circumstance, maybe a bigger battery charger will save someone's life someday. I don't know how, but I'll think of something.
See how the female mind works??
