Go to Target and buy an inverter for your car that will convert the 12v power
to 120volt. Their price varies from $30 to $50. Its better to get a larger
than a smaller one (i.e. avoid the 100 watt one, go for a 200 or 400w one).
One must be careful with those inverters. The cheap units produce quite
"dirty" AC (i.e. the signal is not sinus but contains lots of higher
frequencies too). Impulse PSU-s (like those found in mobile phone or
laptop chargers) can live with that. But if you have a PSU that contains
large transformer it might cause problems because it overheats. I damaged
the transformer of my charger using the cheap inverter. The transformer
made chirping noices but I did not understood what's the problem before it
went off. It took me more than 10 minutes to open the charger and the
transformer was still too hot to touch. Fortunately only the thermo fuse
inside the transformer needed replacment.
Since the LiPo charging is much simpler process than NiMH charging, there
is not much difference between cheap and expensive chargers. So, I would
get an entry level 12V dedicated LiPo charger.

OK, hypothetically here.
Say I'm at the slope but my Lithium charger uses only 120V AC.
So, if I wanted to be reckless (go with me here), what can be done with a
Nicad charger and how?
