I was looking at an FAQ for some small appliance that runs or
recharges from an AC adapter, a black box that plugs into the AC and
lowers the voltage to 12 or less, and maybe changes it to DC.

And it said this was safe, and I too have been assuming these were
safe, but...

Has anyone heard of a short in one of these adapters that sent 110
volts to the thing that was supposed to charge or run off the
adapter???

That would be unsafe, if it happens.

I've heard plenty of stories about them catching fire, which is pretty
unsafe.
