I have a 12v Model CFV Type 1 Black & Decker Cordless Floor Vac which
uses a 12v transformer which I have temporarily misplaced. In the

either of these two settings work OK?

Thanks

Even with a 12v battery operated device there is no guarantee that
the charging brick is DC. I have seen Black & Decker cordless Ni-Cad
devices that will use AC bricks and have the rectifiers on board the
device instead of being in the charging brick.

If you don't know if the brick is AC or DC then purchase a new one:

Why not buy a volt-ohmeter (multi-meter) for 5 to 20 dollars and find
out if the transformer-device is AC or DC? Then he'll have a meter,
if he doesn't have one already.
