Frank,
One product that might fit your criteria is the www.mahaenergy.com/store/viewItem.asp?idProduct=185 (sorry, I'm not at my reqular computer so can't do the web link this time). You'll note that it "Includes a light weight travel autoswitching AC adapter (80V to 240V AC)", as well as a car kit.
I have used the previous model of this Charger for Amateur Radio batteries (the older Charger model didn't include Li-Ion battery capability, or the display on the front).
The product seemed to work well, although at times it was a bit cumbersome to match the terminals on various batteries (the terminals are adjustable for both width and height, in order to match the spacing on various batteries). There's also a thermal sensor that has to be placed on the battery when charging, in order to ensure that no overheating occurs.
Some proprietary batteries are equipped with not only the "+" and "-" terminals, but also one or more extra terminals for voltage sensing or whatever (as determined by the manufacturer). You may need to keep a small voltmeter on hand in order to determine which terminals to attach to the Charger (some batteries aren't marked).
If you'll be using this with NiMH "AA" or "AAA" batteries, you'll need to visit your local Radio Shack store to purchase appropriate battery holders.
Hope this helps.
Cheers!
