you can use a car battery like what has aleady been said your power from your car ciggy lighter is unregulated.
I run my eq6 though on a 240v power supply - 12vdc thing is it runs at 13.8 vdc, so the eq6 is quite capable of handling a bit of over voltage. to give you a idea of what happens with power use ohms law v=I*R. its a balanced equation so as the volts go down, the resistance R doesnt change so the i Amps increase thats where your switchmode psu regulate this.
If you are worried about this, put a alarm on your battery pack that as soon as the voltage drops too low it warns you. the other thing you can do is get a deep cycle baattery that is ment to be deep discharge. you can get a 100 a/h battery for about 350 bucks. now that will run your laptop/mount/dewheater/cameras for 2-3 days. and will last somewhere in the area of 1000 recharges + before capacity starts to dwindle.
