Pawfly Aquarium Battery Operated Air Pump 40 GPH for Fish Tanks up to 30 Gallon, Adjustable Oxygen Pump Powerful Outdoor Aerator, Accessories Inside The Pump（Battery Not Included）

Great little aerator - I use it to propagate plants! The flow of oxygen in water allows them to root faster

Don't have a clue. Delivered in reach of dogs. Guess they liked it.

This is a decent little aerator pump. If you want to keep baitfish/minnows alive in a bucket, or don't need a permanent aerator, it will serve you well. It gives about the same amount of air as any other aquarium pump this size. As other reviews have noted, it's not really quiet, but it is portable, which is the big benefit here. It serves the function that you'd expect from a battery powered pump.My review process: 5*- Blew me away, features that are much better than anticipated (rare). 4*- Product is as expected, and good quality. This is a STRONG review. 3* - Product should function, but has minor flaws. (Average product) 2*- Product may work, but won't last long/cheaply made/major flaws/issues, item failure w/ some remediation from seller. 1* - Poor item/failure during use, or before, no remediation from seller.

I've been running this for about two weeks now. It's much quieter than an electric air pump, which is what I was hoping for. I'm turning it off at night to conserve battery and so far it's still going strong.

I recently, accidentally, became a fish breeder. My fish will not stop having babies and I’ve come to love raising them! But my angelfish have babies very frequently and apparently I’m not the only one in the area- I found a shop willing to buy them, but they are an hour away. This keeps my mind at ease while transporting the juvenile fish to the pet shop. Very easy to use. I also like having it as a backup in case there’s a power outage. It’s long lasting- for as long as many batteries you have at home. Don’t have to worry about charging it. Great product!

If you have too many items "plugged in" electrical outlets, this is a good option, as it is battery operated. 2 D batteries. I like this item, but it is super loud.

This works well and the battery part is great for on the go. My husband got this and I had got another one for myself. He uses his for his bait, I use mine for my plants that I propagate.

This pump delivers a fair amount of air, about what a standard low end aquarium pump does, and it does it via battery power—two D batteries to be precise. It even comes with a short length of air tubing and an air stone. The build quality is pretty basic. There are, for instance, no sound absorbing feet to keep the pump from vibrating whatever it’s on. Like some other reviewers I can confirm this thing is loud. Of course, since it’s battery operated I think we can divine that it wasn’t designed for a typical fish hobbyist to aerate their aquarium, but for someone transporting live fish, so making it bedroom or living room quiet wouldn’t have been a priority. It is what it is. If they’d added some sound absorption and an external power supply option it would have been a jack of all trades, but that wasn’t the design intent. I won’t tell you the build quality is extraordinary because it isn’t. It was clearly built to a price point. For instance, the batteries stretch the case when they’re inserted. Also, the air output doesn’t really work with standard vinyl aquarium tubing—it’s too big, but the included tubing is soft rubber and does stretch to fit that larger than normal output. Despite its shortcomings it works. I ran the thing for five hours on one set of batteries and it was pushing as much air at the end (as near as I could tell) as it was at the beginning. Is it extraordinary? No. But if you’re looking for a basic aquarium air pump, and you need battery power, consider this one. Figuring out how many stars to give it was difficult. I was kind of leaning towards three, but I’ll give it four because I can’t take anything off for what it’s not, and despite its basic construction it worked flawlessly for me.
