A case for portable generators
The convenience and benefits of a standby generator are solid, even if they require a little more attention during a once-in-a-generation storm. However, considering the imperfect nature of standby generators, portable generators are worth considering.
The first, and most obvious point, is price. The unit plus labour costs about one-third of the price of a standby generator setup. It can also come with you if you move instead of being a permanent fixture of the house.
Another benefit is mobility. Since you decide where to run the generator, you can avoid areas with intense wind or snow. It's even possible to run a generator in your garage if you have the doors open for proper ventilation. Assuming you keep the portable generator in a protected place and pull it out when needed, it won't be covered with ice either. With proper maintenance, it will be ready when you need it.
