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)

I used this product for my mad scientist halloween display. It was worth the money and did it's purpose. After halloween I placed it in ma aquarium where I run it a couple of minutes every other day. It's sturdy, durable, easy to use. Battery lasts long enough, it's pretty quiet with pretty decent airflow.

I have four tanks. When we lost power for four days during the last blizzard I chose to use this pump on my largest tank. It saved a lot of fish. I will definitely be prepared next winter by ordering more of these pumps. Well worth the investment.

Works perfect! Pump creates lots of bubbles keeping my bait alive and feisty

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.

Great little bubbler! I particularly like that it uses D batteries. I run it twice a day for a tank with a dozen small freshwater minnows and they enjoy their “oxygen therapy” sessions. I did have to weigh it down with a rock because it kept floating to the top and I wanted the bubbles to come from the bottom. Problem solved.

Worked great for a cross country move, kept my shrimp happy with a working air stone for the drive. Used my wall powered one at night in the hotels, ran this during the day. Only had to change the batteries once in 3 days. A little noisy but not bad, just threw a towel over it to muffle it a bit.

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

Works great a little nosey 😞

Worked great to be able to move fish across the country.

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.

Does the job although quite noisy.

Reallh loud but will do as backup for power outages

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.
