Penn-plax makes a bubbler that cuts on when the power goes out.
Most tanks have an 8 hour grace before they need a water turnover.
It is possible to aerate a tank by dipping up water in a pitcher and pouring it back in from as high up as you can: to do a full job, do as many gallons as you have in the tank. Then you can relax for a number of hours. If cold becomes a problem, know that a tank can go down as low as 63 degrees and survive. But you can slow heat-loss down by wrapping insulation or a blanket or slabs of styrofoam AROUND your tank, while NOT covering the top (aeration.) Hopefully your blackout will not as long as ours was (8 days) and all will be well.
