a long while back we used an inverter to run a PS2, before the days of the slimeline PS2, it was a 500w inverter, and it just made the transit drink the fuel, back then the invertors where not very economical, the large ones anyway. After about 6 hours the invertor fried its self. But if you want your invertor to last longer, I suggest you get an inverter double of what the appliance uses power.
I now use my macbook in our own 17 seater, so no more heavy invertors dont wana f*** the alternator, I bought a 120w invertor from maplin a year ago my macbook only uses 65w and its lastes since. Its very small and portable, and its the only inverter i have bought which has lasted.
I use a dc power converted to run my laptop in my transit 12vdc to 19vdc. (again from maplins) If possiable, i would suggest you use a dc dc converter than a dc ac inverter.
I also strongly suggest using a dc to dc convertor, as its much more economical in terms of power.
If only i could get one for my macbook
