Portable Backup Generator Sizing

A small portable gasoline generator in the 1,000-watt range and an extension cord can operate a microwave oven, a TV and a few lights. You MUST put the generator outside in a well-ventilated area and pass the extension cord into the house directly to the appliances. If you want to keep the refrigerator running, a number of small appliances, and more lights, upgrade to a 2,000-5,000-watt generator.
