We had a two week outage after Hurricane Wilma, and several homes on our block had gasoline generators (which were as rare as hen's teeth at the Home Depot and Lowes stores--they basically sold out every shipment before it even arrived). The neighborhood sounded like a bus depot with all those motors idling. Basically, yes, you roll your portable generator out into the yard start it up and run one or more heavy duty extension cords back into the house. A gallon of gas will usually get you 10 hours or so of power. The oil needs to be changed every 12 hours or so. Of course, every hurricane season we have at least one tragedy when somebody who doesn't read the manual tries to run one indoors or in the garage and wipes out his whole family with carbon monoxide fumes (this year there were two). Best bet is to get a carbon monoxide detector at the same time you buy the generator--looks like a smoke detector, costs about the same. As for capacity, the itty bitty ones are really just for running a few power tools out at a job site. Make sure you get one that can handle at least the refrigerator, a lamp or two and the TV. These will also have 220 outlets as well as 110 on the outside, so you can run the washer or dryer from time to time. The big natural gas powered ones are ideal, of course, but they start at 4 grand before installation. Gerald Owens
