Just a couple of weeks ago I ordered the charger you pointed to, tried it
and immediately returned it.  The batteries (AA and AAA and D) got so hot I
couldn't hold on to them.  Larry Chase had the same experience with that
one.  I then ordered this one:

on Larry's suggestion and it seems perfect, have charged all sizes in it
without problem.  And it let me know that one D cell I had was bad.
As for 12v charging the one I have now does not come with a 12v adapter BUT
it actually uses 12v DC out of the wall wart so I will cut the cord and put
a connector on the plug that mates with a 12v plug and cord and be able to
charge on either 110v AC or 12v DC.
BTW, the AA/AAA smart charger that sells for about $59

 is
probably the best on the market and as I use up my current supply of AA and
AAA alkaline batteries and switch to all rechargeable I'll probably go to
one of those.
