Scheduled Power outage worries

There will be a scheduled power outage where I live for about 3 hrs. Will my tank be ok as far as oxygenation and temperature goes? The tank is 30 gallons with a single fish so I hoping oxygen does not get depleted too fast.

Get a backup battery bubbler.
It been a life saver to many.

How many should I use? Will just one suffice for a short outage?

Yes.
One is enough but get plenty of batteries for it.
