12v or 240v Inverter?
I've had no problems whatsoever running the laptop (19v) via it's mains PSU and a cheap (£24.99 from NETTO) 150W inverter. This will most certainly not be 'pure-sine-wave'!
I've also used DC-DC converters (technically these are inverters also, but they change the output back to DC) with mixed results. I've had two of the very common cheap ones -(about 2inx3in, curved at top and straight at bottom) which both failed after a couple of hours.
I have another, smaller and rectangular, which has had extensive use over last year and works perfectly (this one has assortment of funny little plastic plugs which select the output voltage).
The DC-DC is more efficient, and has lower idle current that the 240v inverter, so generally use it for the computer. However, it creates a lot of interference if listening to internet radio relayed to the car radio! .....so have to change back to the 240v. Oh! Well.
