AC Input to DC Chargers

[wgalligan]

Ditto on the car battery.  I had a 10 amp battery charger laying around and
since I am in the car business a cheap battery has proven to be very useful.
Makes a good weight when sheeting stabs and wings too.  And it has other
uses... like when the kids leave the lights on in the car and there is no
one around to get you jump started.

I purchases an AC Delco "discontinued" car battery from a local battery
store for $22. (65-84, 850CCA).
I keep it well maintained with a 2amp charger.
It's easy to store, and it satisfies my bench charging needs...croz
