Please note that wealthy celebrities, dem donors, and super-rich politicians likely all have standby generators which keep the whole house running fine during power outages and are not considered portable. Portables are just for the unwashed rabble, you see.
I’m not wealthy but just the same, been thinking about having a Generac installed. House is already plumbed for natural gas. Live in Texas and don’t need another one of those supposedly 100 year deep freeze ice storms. Last one cost me a butt load for reconstruction.
