Hi Criss,
I have Powertech Power Inverter bought from Jaycar a while ago for about $50 dollars. I explained to Jaycar guy that I intend to use car battery for powering my laptop and he recommended this Power Inverter.
My Asus Eee PC uses 19V 2.1 A. So according to Jaycar guy this Inverter is the best solution since it converts from 10-15 V input to 240 V and I simply plug in laptop power cord in it as in the wall power outlet.
But car battery is not designed for this kind of use and can't last more than a few hours. I visited SuperCheapAuto today and saw Century 12V 26 Ah Deep cycle battery for $129 dollars but they dont have it in stock here, maybe next week.
Similar one Jaycar got for around the same price.
