As to runtime, buy a 120 watt inverter built right into the cigarette
lighter plug for it. Plugged into the house battery, it should run it
down
in a week or so. You won't notice it as a load.


I have a slightly larger inverter on the boat so battery life isn't an issue
there. I have found that the ASUS battery life is pretty minimal, about 45
minutes on a full charge. That's enough for a quick email or weather check
during an air travel connection but not enough to get through a short
flight. I expect my use away from a power plug to be pretty minimal though.

I had one of those little direct plug in inverters and it burned up while
running a laptop.
