The Breza Battery Powered Air Pump is great for transporting fish over long distances or for use during power outages. It comes with a sensor, that you can plug into a wall socket, that detects when there is a loss of power. When there is a loss of power the pump turns on. It requires two D size batteries that are not included. It includes an air stone and about 20 inches of air line.
Rivers to Reef says: Please remember these DO NOT run off of the plug. The plug is just a sensor to detect if there is power. When it detects a loss of power then it turns on. If you have a sponge filter running in your tank, you can transfer this onto it when the power is out to have both aeration and filtration during the outage.
