Hi Joy,

Have you looked at high-end laptops recently?  Extra-bright 17"
monitors are common. DVD-burners are standard equipmment, and
powerful speakers to go with them. They throw off a ton of heat, and
to do that they draw a lot of watts. That means that they're built
with large-capacity batteries, and if you want to RUN the laptop and
charge it at the same time you're drawing twice as much power.

And as I mentioned in an earlier post, the ratings on inverters
recently has little or nothing to do with what they actually produce.
True output is more like a third of rated output.

If someone wants to try to run and charge an "executive class" laptop
I wouldn't recommend purchassing anything less than a 300W  rated
inverter.

Happy trails,
