I ended up buying the 13.5V unit, since it can be adjusted upward to
simulate battery charging voltage, or down to 12V if I wish. The
adjustment is easily accessed without opening the case, tucked in
with the terminal strip. Looks like a pretty decent product at a
very attractive price.

I used about a half dozen of various models in projects
over the last two years. Got two of them on the bench right
now. Just be careful when hooking these guys across batteries.
Some of these products don't like to be reverse powered when
their ac input power is removed. I use a fat schottky in
series with the output to prevent tug-o-war issues. This
means you might want to order the next higher voltage
next time . . . but there's one resistor you can change
inside that will boost the output if necessary.
