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,

Greg Potts Toronto, Ontario, Canada
