Having an elder living with me and do to some health issues it would be nice to have power given any circumstance. Is anyone generator better than the next? Looking at a unit that would allow for heating in the winter, AC in the summer, lights, charge batteries for night time lighting and not having to run the generator, Things to consider would be noise and fuel consumption. Thinking portable but not ruling out an automatic gas back up system. Any personal experiences with either? Thanks for your input.
