No, you've got exactly what you need if you got a supply specifically intended to run a laptop from a vehicle supply.
I probably wasn't very clear. What I meant was that you couldn't just get a piece of cable and a plug and run a 19 Volt laptop directly from a 12 Volt battery.
Regarding my remarks about chewing through batteries.
How long it will last will depend on how much current your laptop is drawing, how much the other equipment is drawing and the capacity of your deep-cycle battery.
While Mark's laptop might draw 0.9 Amps with a peak of 2 Amps, yours might be different. As I said, if you're only getting around 1.5 hours from your laptop battery it could be a reasonably hungry beast.
