It will automatically detect a power outage and turn itself on, so you don't need to be there to activate it (just make sure the power switch is always set to "on"). You plug its power cord into an outlet and that is how it detects a loss of power. But the power cord neither powers the unit, nor can it charge the batteries. This is strictly a battery-operated back-up system and is not intended to be an everyday air pump. The supplied air line is absurdly short for most applications, so be sure to pick up your own. Also be sure to purchase and insert a back flow preventer (not included) into the air line to prevent water from flowing back into the pump, which will destroy it. I gave this product 4 stars instead of 5 because it is absurdly loud, which is unacceptable in an era where most manufacturers have found a way to make these things whisper quiet. How loud is it? Even if you put this thing in a cabinet, if your aquarium is in your bedroom you would never be able to sleep. Despite that one complaint, every aquarium owner should have one of these. I consider it as essential as having a heater and filter.
EDIT: I was without power for a week after Hurricane Sandy. I can now confrim that it lasted 6 straight days on the same set of batteries I mentioned earlier in this review that ran 8 hours a year ago. A fresh set should give you at least 7 days. Outstanding.
Pros: small, uses D batteries, last a long time, works when power is out and delivers what it is supposed to do.
Cons: Loud. this thing is loud but I have an aquarium cabinet and I put it under there on the shelf and I never heard it when the power went off. So if you have it out in the open, it will be loud. Suggest placing a cloth or something underneath it so it will cut down on the noise.
Overall, I love it and will not be without one. I only gave it 4 stars because it is so loud. The rest is definitely a 5 star.
Note: I don't think you need an air stone. You can just tie the air line to your mag float and drag it down near the bottom of the aquarium. Make sure you test it to make sure you get good surface agitation though.
I have no idea how long it runs but I imagine you could tie in an extra battery bank very easily and it would run for a week. 48 hours seems to be the average after doing research. You need extra air line to run this thing as well as a check valve.

Bought 2 and they have worked great in tests. One is in a 10 gallon and one in a 30 tall. Has no problem making plenty of bubbles in the 30 despite fairly high water pressure.Published 4 months ago by George
