Uniclife Battery Operated Air Pump 40 GPH Aquarium Portable Outdoor Aerator for Fish Tanks up to 30 Gallon – Battery Not Included (with Air Stone and Airline Tubing Accessories Inside The Pump Body)

I needed an emergency fix because I lost power during Hurricane Helene and my fish were in jeopardy. I ordered on line via Amazon.com because I wasn't certain it would be available locally since many stores were without power. It really works great, my fish immediately went to the bubbles that it was creating. My only problem was that it needs 2 D-cell batteries and they do not last long, that would be a welcome change but this little pump does its job very well.

I ordered 4 of these to get my 4 medium sized goldfish from my old apartment to my new house. I bought a blue 5g bucket with a lid from Lowe's. One pump was enough for the job, but I'm happy to have extras on hand. One stone puts out an impressive spread of bubbles, and the batteries in the pump last all day. Operation is simple, and the clip on the pump made it possible for me to attach it to the side of the bucket for easy transport. If you use a bucket like me I would suggest drilling a hole through the top of the lid for the air tube to run through, and clip the pump to the bucket handle or attach it in some other way.The noise is as expected. Most air pumps are fairly loud by nature and this is no different. For my purpose I didn't care, but if you need a quiet unit I recommend you look elsewhere.Someone answered a question saying that these can be used as a primary aquarium air pump because they can be plugged into the wall and then the batteries will only kick on if the power shuts off. That sounds too good to be true, and it is. There is no way to connect the pump to an external power source, so these pumps are ONLY battery powered.

I bought this battery operated air pump as a backup for my aquariums. I have two of these and the airflow is good. Lots of bubbles. It is a good quality product. The only thing negative comment I have is it’s a little louder, but still gets the job done. I have them on a 29 and 40 gallon tanks when needed.

I originally bought a few of these to help me on a move 700 mile move. They worked perfect and kept my fish alive. I have since had to bring them out when the power goes out due to bad weather here now and again they work flawlessly. My only complaint really is that they are loud; much louder than a normal air pump in fact.

Reasonably priced!! I have used this product when electricity is out, also when moving, I have brought my clown fishes from port Richey Florida to Arkansas, then from Arkansas to Jacksonville, then from Jacksonville to St.Augustine … winner of a product my clowns are happy at there new homes 😊

I bought this to use during power outages. I tested it briefly when it first arrived and it worked fine. Now that we have had an actual outage and I needed it to work for more than 20 seconds, it does not work, but rather sputters for a minute or two and then stops working. It is new, but outside of the return window so I am stuck with a defective air pump and need to buy another.

The media could not be loaded.

I bought this pump to avoid the death of my fish when the power goes out. The pump is small and easy to use. Our power was out for 20 hours and the air pump was still running when I woke up. I have a 30 gallon tank with some huge goldfish. The water was expectedly nasty because I don’t have a battery operated filter but the fish survived because they had plenty of air. The noise isn’t any louder than my electric air pump. The price was right!
