Usually, the charger consists of a battery holder and a power brick
that goes into your 115/230v outlet. You could bypass the powerbrick
if you have a DC-DC converter (unstabilized, for this purpose) that
supplies the correct voltage. They're a few bucks if you need
something = 12v. 12v is easy ;-) Unfortunately, 19.2 v 12v ... So
maybe get a 7 to 9 v drill is cheaper!

I use this to charge DC-powered non-12v small appliances that don't
come with their own "car adapter".

I have a laptop 12v power supply with varyable output voltage up to 24v.
These should be as readily available in the US as they are here in UK. Try
an electronics shop such as Radio Shack.
