Permanent generators are more convenient, and because they run on natural gas, the switch is made almost instantly after a power cut is detected. It is beneficial if you are not home when the power goes down, as the sensors will pick up the loss and automatically start the machinery.
While portable models will cost you a couple of hundred dollars, the permanent ones are more expensive and can range between $2,000 to $6,000, depending on their performance.
