There is a need for caution with portable generators, however, and its important that you only use them for their intended purpose. For example, if you are using it for a power outage, make sure you do not overload it. You will not be able to keep every appliance running as normal but should only use it for the essential appliances. It is only designed for corded electrical appliances and should not be used for appliances that are hard-wired to your home. Keep this in mind if you use these for health reasons.
Never run a portable generator inside the home. They produce carbon monoxide which could be very dangerous. Another thing to have in mind is that the generator will become hot as it is running so be very cautious when adding gasoline.
Yes, owning a portable generator has many advantages but, as is the case with all types of machinery and appliances, care should be taken when using one.
