A standby generator for a home or business provides a near-automatic source of power in the event of a blackout. As soon as the generator senses that power to the home/business has been lost, it will power on, allowing you to run the lights, charge your phone or computer, and even run some appliances, like a refrigerator. At the very least, a standby generator provides a heightened sense of comfort and security; and the very most, a standby generator could be life-saving.
