Get the Champion with the remote start feature. Run a dedicated quality extension cord near the electrical outlet that you currently use to plug in your O2 machine. When an outage hits, you just have to hit the remote start button, then unplug the O2 from the wall, and plug into your extension cord. You're good until the power returns. (Or, move to a state that has a better power grid).

Your looking at a $1,100 plus shipping and taxes portable gen..



Not sure if this is for home use, but it seems to sound like it is.

OP will have to drag it out from storage, make sure there is gas and oil in it then start it and then run extension cords all through the home for these random power outages.

For home use and with the health issues the OP seems to have, they are going to be far better off to spend the money on a small whole house gen with auto changeover ATS.

This will provide nearly zero downtime on any priority circuits in the home and it will do this all without every needing to get out of bed in the middle of the night.

Small whole home systems can be typically had for $4K or a bit less fully installed and depending on what you have for available fuel sources you have Natural gas or Propane options to work with in that price range so you don't have worries about stale Ethanol gasoline fouling the carb or if you have gas on hand or if you can get gas.

Best of all, no running of extension cords, no need to switch devices to a extension cord and less hazards of tripping on cords or folks operating gens inside garage or home or to close to home.

Alternately but much much more expensive is a home solar powered backup power system that acts as a UPS (Uninterruptible Power Source). The Cons there are they are insanely expensive when adding up costs of batteries, solar panels, charge controller and decent Inverter with automatic transfer switch.

Grid tie typically is not an option unless you spend more money for a grid tie inverter that has "islanding" capabilities and you would still need batteries for in the middle of the night interruptions. Grid tie inverters are typically designed to shut down in the event of a PoCo interruption and also typically do not have storage batteries.
