I have powered my laptop all night with a 150watt PURE SINE WAVE inverter and just plug the normal 240v plug into that.
(Don't get a cheaper modified sine wave inverter for sensitive electronics)

But if you can get a specific DC - DC power converter (to change from 12 volt to whatever voltage your laptop requires, with its correct plug type), that sounds like a cheaper option than PS Inverter.
Thanks Guys

I have seen the Waeco units used to power a big Dob with heaters, fans and Argo Navis for several nights before. One of these units is on my hit list. What brand of inverter as you using Allan?
A netbook wont pull as much power as a full laptop so 33AH should be adequate (I think)
