Pawfly Aquarium Battery Air Pump 40 GPH Oxygen Pump for 5 to 30 Gallon Fish Tank Portable Aerator Pump for Outdoor Fishing and Fish Transportation, Battery Not Included (Accessories Inside The Pump)

Works really well. We’ve lost power a couple of times and this came handy for our saltwater tank with corals. I guess the battery life is pretty good so far, haven’t had to replace yet. Priced fairly well. The noise level is what you would expect from these battery operated air pump which doesn’t bother me. Highly recommended.

I recently purchased this bubbler, and I couldn't be happier with its performance. In a real test of endurance, it ran continuously for over 55 hours, and the results were astounding. I needed to keep a dozen shrimp alive in a 5-gallon bucket, and this little device proved to be a true lifesaver. Pros: Exceptional durability: The fact that it ran non-stop for more than two days without any hiccups speaks volumes about its build quality. Efficient oxygenation: My shrimp were as lively as ever, thanks to the steady supply of oxygen provided by this bubbler. Easy to use: Setting it up was a breeze, and it worked flawlessly from the get-go. Compact design: It doesn't take up much space, making it ideal for smaller containers like my 5-gallon bucket. If you're looking for a reliable bubbler to ensure the well-being of your aquatic pets, this is the one to go for. It passed a critical test with flying colors, and I have no doubt it will continue to perform admirably. Highly recommended

I keep guppies. Every few weeks I need to offload some guppies at my local fish store. I pop batteries into this bad boy and hang it on the side of my 5 gallon bucket and we’re off to the races. It works, it’s noisy, but it works. Have used it multiple times and still does fine.

Nice air pump.. bought this for emergency when have power outages. It worked perfect. Fish were very happy. Battery life was really good and hardly any sound. Good value for money.

This was amazing! I bought this to move my 4 fish from Oklahoma to Texas, a 10+ hour drive. I popped the fish in a cooler and placed this in there with them. It worked! It kept them alive. I even used it for about another month before I could get an actual tank set up for them. I highly recommend this. The only downside is you will go through batteries, so make sure you stock up if you plan to use this in an emergency or for moving.

It works very well but it’s so loud that it scares my dog, so I can’t really use it lol.

It has worked for multiple days without changing the battery. I used it for a 5gal bucket overnight and traveling all day while fishing, then most of a day during a power outage and it's still ready to go. It has enough power to keep my 20, 10, 1, and 2 gal alive all at the same time. I just disconnected my existing tubing from my usual bubbler, connected this one, and adjusted the valves a bit. The bubbling wasn't crazy but it would have kept the tanks alive for a good while.

Battery powered, bought to keep my axolotl alive on a 12hr drive/move. It did its job! It's a bit loud, the humming vibration, but not enough to be a bother. It makes a lot of air bubbles into the water for your aquatics. Batteries kept going for over a week while I got his new tank set up.

Bought to use in a power outage, which happened here today. Pleased to say this air pump works really well, although it is VERY noisy. Not an issue for me as I don't have any of my aquariums in any bedrooms. Have bought a couple more, for the same reason, for my other tanks. Update: Yet another power cut. This one lasting 36 hours and I can confirm that this air pump is amazing. The batteries lasted the whole time and I was able to set one up so it worked on three tanks at the same time. Another covered two. Great product to have as a back up. Would highly recommend.

Exceeded my expectations. Works well for a short term thing in smaller tanks. Love my bubbler. Very powerful.

Great little product! Purchased for our little goldfish pond. Came the day after ordering, well packaged and simple set up. When you take it out of the box, everything you need is located in the battery compartment - Nice thick but malleable air pipe and a little air stone. The air stone produces loads of little bubbles and my two little fish seems to enjoy it. Not silent but not really loud. Really good value for money. So far I've ordered two - Will be ordering again. Highly recommend.

Works as it should. Doesn’t eat batteries like others I’ve tried

Does the job although quite noisy.
