Good advice. To add to it, one of the best chargers out there right now is
the Ray-O-Vac 1 hour charger available at WallyWorld, etc. It's $29.95 and,
depending on the particular package, comes with either 4 1800 mah batteries or
a car cigarette cord. This charger contains 4 individual charging circuits so
you can put 4 batteries in, regardless of the individual state-of-charge, and
have them all charge properly. On 2300 mah batteries it takes about an hour
and a half to charge.
For external power, if you don't mind connecting some wires (or getting
someone to do so for you), a very cheap option is a small lead-acid battery.
You can buy a 4 ah 6 volt battery at Lowe's, etc, intended for emergency EXIT
signs, for about $15. It's about the size of a cigarette pack only twice as
thick. From radio shack you'd get a barrel connector cord (like the one on
your charger) and an appropriate wall wart to charge the battery with. Just
connect 'em up and plug it in to the Jukebox. 4 ah is about twice what the
internal batteries have. The combination of internal and external is 3 times.
The battery and the Jukebox will fit in a small camera case that you can wear
on your belt or carry around. The battery is about the same weight as the
Jukebox.
I'm about to write up an article on how to do this, complete with 8 X 10 color
glossy photographs (or the web equiv :-), so it will be a cookbook type job.
