Find the wattage and power requirements of each appliance on the faceplate or in the owner’s manual. Generators can operate several items at once, or just one item at a time.

Generators come in various sizes and portability options. A small portable generator powers the basic home appliances, small stationary and midsized portable generators power more items, including a computer and more lights. As the sizes get bigger, the more they can power, and the more they cost. Stationary generators are always ready to turn on if needed and they stay in one spot.
