Emergency O2 solution for power cuts

[schooncw]

My 120 LPS dominant system is overstocked with fish and coral and in my condo, rarely get a power cut but had one recently and fish were gasping after 2-3 hours.
I am looking at hygger product that ONLY comes on if power cuts.
Any suggestions for emergency air in a power cut? I don't use Ecotech.

I have a UPS for circulation pumps.

If I am home I grab a siphon and a bucket and start moving water around. Probably not what you are thinking about but I wanted to post this here for folks who are looking for solutions during a crisis.

If you want something more multi-purpose, then I think cordless power tool batteries are fantastic. Pick a brand that also has a battery to power socket converter and you have a quick backup for simple devices. Airstone pumps are low energy and cheap.
