No one likes when a power outage hits their neighborhood, especially if the power is out for a prolonged period of time. While a power outage can be a nuisance, it's barely disruptive if you have a generator. A generator is a simple, gas-powered device that you should think about owning. You can buy generators of all sizes at hardware stores. A visit to the store in your area will give you a chance to check out some models, talk to a salesperson, and find a generator that will suit your needs.
