Automatically switches to battery use during a power outage
Powerful air flow with 5 adjustable levels
1-year hassle-free warranty
The air pump you've always needed is here. Keep your aquarium water well-oxygenated and your fish healthy in absolutely any scenario — even when the power is out. To give you peace of mind, the Aquarium Co-Op air pump utilizes a rechargeable lithium-ion battery that automatically switches to battery use if it loses power. It can be run continuously for approximately 20 hours on a single charge and can run in Power Save mode (where the air cycles between 15 seconds on and 15 seconds off to conserve battery) for 40 hours or more. Note: the printed manual has not been updated yet and incorrectly states that the battery runs for 8 and 16 hours.
Quiet Operation
Designed to run quietly, barely above the sound of a quiet library. Its sound levels are lower than a normal household room with everything turned off. In fact, the bubbles from the air in the water are louder than the pump itself.
Storm Ready
Our air pumps have a built-in lithium-ion battery. When the power goes out, the air pump continues to run automatically. Works as normal when plugged in via USB Type C and then continues to run when the power is out. If anything happens, you can trust in our 1-year, hassle-free warranty.
Up to 40 Hours of Battery Power
Our air pump has a nifty Power Save mode. By turning on this feature, the air pump will turn on for 15 seconds, then off for 15 seconds in a cycle. This extends the battery life up to 40 hours, keeping your fish oxygenated during a power outage.
Adjustable Air Flow
Push the arrows button on the pump to set the amount of air flow. The 5 flow levels can be adjusted to create a nice, slow flow for fish like bettas or reduce the bubble noise if needed.
Delivers Air to Both Shallow and Deep Tanks
We built this air pump to be used with both nano tanks and large, deep tanks. It is powerful enough to run a sponge filter in Cory's 800-gallon aquarium, which is 40 inches in height.
Powerful, quiet, compact, 5 level output, battery backup with a power save mode and for a good price. This little air pump checks all the boxes.
Thanks Aquarium Co-op!

Great Pump
Very happy with the air pump. I like the fact that the air pump is adjustable and has several settings for flow. The pump is pretty quiet and has a small footprint. Great pump to have handy when the power goes out to provide surface air movement.

Air pump with battery back up.
Installed yesterday on my five gallon Betta tank. Quiet with perfect, gentle flow just as promised from the Co-op. Cory delivers and never disappoints.

The Best Air Pump for Peace of Mind
We have experienced enough power outages due to bad weather in our area for me to feel uneasy running air pumps other than the Aquarium Co-Op Air Pump with Battery Backup. It’s reliable, super quiet, and simple to operate. This ACO air pump is a total game changer for me while I’m doing large weekly water changes breeding different species of fishes and invertebrates. I can have peace of mind knowing that my air pumps will continue to run if the power goes out during a bad storm, or if I’m taking on 50-80% water changes on 7 tanks in one afternoon. Water changes sometimes don’t go as planned in this house with a baby, so having this AWESOME air pump is essential in my slice of nature :)
