I know some of you avtards haul generators out into the backcountry for that back-to-nature camping experience. Here's a great watt meter that will let you know exactly what your various appliances are drawing:

I used to measure the electrical draw of various appliances around the place with a $5 multimeter. Always one for safety, I carefully held a small screwdriver by the insulated handle and jammed it into one side of the outlet, held one prong of the plug for the appliance against the screwdriver with one hand, held both leads of the meter in the other hand, pressing one of them into the other side of the outlet and the other lead against the other prong of the plug. Multiply volts times amps to get watts. Needless to say, it worked great if you discount the fact that I got bit every single time I did it. I like my new meter!
