Actually, the unit I had in mind was a solar trickle charger, not
110v, and that was more what I was asking about than the AC type
units.  Does any one use one?  How much would it put back into a
battery given a moderate day of sunlight to charge, given that most
of the time I would be using 12v would probably be evening stuff
(lights, maybe evening movie in a laptop, something like that.)

Any thoughts?

David.
