Every aquarist should have one of these!
Somebody out on the highway hit a power pole about 45 minutes ago. They had to de-energize it for awhile, which meant our power went out. My Azoo non-stop pump battery, which I have on the low setting, took over and powered my airstone in the absence of electricity.
Every aquarist should have one of these. They can be a lifesaver during a power outage, if it doesn't last too long. The battery on the low setting will continue to power the tank for up to 20 hours on a full charge, and on the high setting about half that long. As soon as the electricity returns, the battery recharges.
Sure beats having to gas up a generator (which we don't have, anyway)!
