It seems to me that I've seen a device advertised somewhere that was
an emergency electrical pack for your car. It had a battery -
presumably lead-acid - large enough to start one's car if the car
battery dies. It also had a "power outlet", which is basically a
cigarette lighter socket, from which you could run car accessories. It
had a handy carrying handle and I think even had a built-in light. And
you just plugged it in to charge it. It was consumer grade and not
overly expensive. If you were handy, you could probably even open the
case and insert a small voltage regulating circuit and an additional
power jack for the necessary voltage for your particular equipment.
Seems like this might be a handy power source for recording. I wish I
could remember where I saw it. I'll keep my eyes open...
