Battery backup or UPS?

[Myka]

Just get a quiet generator with a good muffler and put it in a detached garage or shed and your neighbors won't hear it. Those bylaws only count if it's a disturbance.

we have a battery backup from crappytire that can also charge your car, picked up a decent generator after that last outage where people were out for days, and some battery airpumps.
But I have my family looking out for UPS backups on boxing day. It will be my luck that the power will go out the moment everyone leaves for work so there wont be anyone home to plug stuff into the our battery.
I want something to plug my powerhead or return pump into that will keep it going on its own until somebody gets home. My sump wont overflow either, and I have no idea what wattage my return pump is, but my main powerhead is only like 4w....

I use a Marina battery powered air pump, works awesome to keep the aeration in the tank, when we have short outages other than that I have a backup generator that powers up all the fridges, freezers etc. as well as my entire tank.
I have a BNIB spare Marina air pump if anyone is interested $15.

Don't even need a battery powered air pump, all you need is a potato and hydrogen peroxide and a plastic bottle

You chop the potato into small cubes, place in plastic bottle.
Then add enough hydrogen peroxide to cover the potato cubes.
The lid needs to be drilled so an air tube can be run through it,
Seal bottle and place tube with or without an airstone in the tank.

Hydrogen peroxide naturally breaks down into 2 components over time, water and oxygen, the addition of the enzymes from the potato speed this up 100x
The escaping oxygen gas will travel up the air tube into your tank, providing pure oxygen to the water.
