You can hide a few air lines within your rock work. When the power goes off, the ac plug switches the battery operated air pump on. You will get many hours out of the battery. The B10 model is just an air pump, while the B11 model has the auto-activation when the power goes out.

Has anybody tested how long these puppies last before the batteries die?
