My wife's car is dead. It's in the garage, a hard push uphill to get
it out to jump-start, so I figured I'd build a battery charger. We
still have our old DSL modem, and it has a huge 21-volt, 1.1 amp
wall-wart, so I hooked that up. 3.1 amps... if I left that on all
night, it would probably die... seems to be a 60 Hz xfmr-type, so
probably has a thermal fuse. Adding my Makita belt sander in series,
tie-wrap on the trigger, gets down to 1.3 amps, good enough in a cool
garage. Maybe it will start in the morning.

So I should buy a real battery charger some day soon. Are they still
big klunky transformer-rectifier things? I'd think that some nice
small switcher could manage a few amps at least.

I bought one from this company to charge my 48v gokart. It's switching
style,
3 stage charger. The smallest 12 volt charger they have is a 12 amp.
Might be overkill for you but I wanted the 3 stage to better care for my
gokart batteries.
