I saw a car battery recharger for $60 in the Rand McNally map catalog.
If your battery is dead, you plug this into your cigarette lighter, and
it recharges the battery (enough to start) from a D battery.  It seems
like a neat idea.  I have a few questions:

1. Has anyone used one of these?  Any comments?

2. Can I build one of these myself?  I've built computers, etc.,
before, and I have access to lab equipment.  Anyone know where I could
get plans?  

Thanks.  Please direct follow-ups to the appropriate group or email
me.
