If only everyone organized a backup for everything that can fail. IT doesn't matter so much if you are not disabled. But its pretty much essential if you are. Not had a power-cut here for years. A few brownouts while someone fried but nothing that puts the lights out. But it can still happen. Even large parts of towns go black every 10 years or so for a hour or more on average. Shit happens.
Did have a trip go, that powered my room, but lights still worked. So I reached for my beds power socket (converted to Anderson from its wall brick,) and plugged my leccy bed into my chair. Cant manage without that working. And when a carer came she flipped the AC trip switch back on. After about 10 goes and a lot of trying to describe what to do! Having Anderson on everything helps. I could have got AC too from the chair(s) from an inverter for anything else needed.
And if long term out, I can connect the house to my vans output, via an inverter too. And extension cable. Leave it idling, and everything works back fed through a wall socket. Turn off at mains. You dont want to feed the grid!
