USB Aquarium Air Pump, Ultra Durable & Quiet USB Nano Air Pump, Small Air Bubbler for Aquarium Fish Tank with Air Stone and Silicone Tube

Little work horses! You need some quick, compact, easy, quiet air? This is for you. It's not a monster, but it's a solid performer. I use these to keep premix topoff jugs aerated/mixed. They conveniently hang right from the handle on the jugs. They work great for auxiliary stones anywere you need something quick and easy. Feeder tanks, quarantines, mixing, etc..

Pros- small but works very well. Cons- I put in my fry tank and had to get a control valve since it’s too strong and it gets HOT. Like I can’t keep it on all day because it gets very hot and I’m nervous about it causing a fire. (I think it’s because I have to turn down the pressure that it gets hot) Definitely recommend for larger tanks!

I purchased this a while back but didn't use it right away for various reasons, so it sat in it's box unopened for a year. When I did go to use it, it did not work. It made a bit of noise but that is all. I can't see why it would die over a year of being unused. It's not milk that has be left out on the counter. Of course I'm way past the date where I could return it for another one. I'll just have to buy another from elsewhere.

UPDATE: I bought a "USB LED strip light dimmer switch" on Amazon in hopes I could use it instead of a tubing flow restrictor, and it works great! I was able to finely and easily tune the bubbling amount. The pump is now entirely silent and all I can hear is the bubbles. My USB tester says it uses only ~0.15 Watts on average, 1/10 the original amount out of the box, and it runs on maybe 1.5 Volts as opposed to the original 5 Volts. I totally recommend buying a USB dimmer switch for use with this pump to reduce noise, airflow, and power consumption if the pump is too strong for you, out of the box. The voltage adjuster I bought has a dial on it as opposed to +/- buttons, and I suspect the dial is better in that it has a more fluid/analog, mechanical, simple voltage adjusting mechanism. One of the other tiny air pumps on Amazon has a built-in voltage dial, but I like how having a separate dial can allow me to replace one part without the other. Someone should start selling these pumps as a combo with dials. Original review: This pump is so strong, I was skeptical of the 0.2 Watt claim. I think the vendor meant to say it's 0.2 Amps, not 0.2 Watts. At 5 Volts, it's actually 1 Watt (as can be seen in the photo as well). I was looking for the lowest airflow pump on Amazon because I got this for my tiny ~5 cup (~1 liter) Sea Monkey tank. My Sea Monkey tank is so small that I initially elected to use a flow restrictor on the pump tubing, and it seemed to work well with the flow restrictor.

I use this pump to aerate a small hydroponic system. It does a good job pushing the air, but the airline pops off every few days, even after securing it as best I can. It is super quiet, and relatively inexpensive, so as long as the line stays on, this is a good deal.

This pump is genuinely silent. The only noise from it is the sound of the air coming through the stone. It's very impressive. I used it to help my aquatic pet as I moved across the country, and it let me keep her aerated using the usb plug in my car as well as the ability to use a portable charger when I needed to. It worked out great! She made it, and it was definitely largely due to this stone. Would be great for fishing as well, but I use it now as my tank's main air pump because the big one is so loud! This one is so quiet. It's amazing. 10/10 from me.

This is the best, most powerful (portable or not) pump you can buy! For such a compact size, this pump will outperform many larger plug-in pumps out there. You will be surprised! I purchased 6 pumps in a pinch because we upgraded our electrical panel and power was out for 8 hours. We have (2) 29gallon and (1) 75 gallon tanks. I ended-up using only 4 of the 6 pumps because the 29 gallon tanks only needed 1 pump each because of the incredible pressure the pumps produce. I decided to stress test 2 of the pumps on the 29 gal tanks after power was restored just to see how long they would last on my 10000mah usb power bricks. Each of the tanks were powered by their own Anker 10k-mah power brick: only down 50% in 24hrs for both tanks. Simply Amazing!!! Icing on the cake: the pretty good-sized air stone they come with put out the finest air bubbles that saturated the tanks with oxygen after 12hrs, so oxygen bubbles were forming on the leaves of the plants in the tanks. The pumps work so well I decided to replace an old pump on a 4 gang plenum for (2) 3gal nurse tanks with the portable powered by an old 1watt iPhone usb block; just to see what happens. I had to release some air out of one of the valves because the pressure is too strong for tge little airstones in the (2) 3gal tanks. The little usb pump has been running strong for almost 3 weeks now on the Apple 1watt block. I highly recommend this usb pump. It's definitely worth the price and delivers with excellent performance. I'm glad I found this little pump here on Amazon.

The air pump is great, I have it running a bubbler in my .5 gallon sea monkey tank. The tubing was not great and kept popping off - the pump is not adjustable so I have to use an air control valve to make the bubbler not too strong for the sea monkeys, so the pressure kept eventually popping the tubing off the pump. I replaced it with some stiffer tubing I already had and it is fine now. Been using it about 2 and a half weeks now, and everything has been fine. UPDATE: After about 4 months it would randomly stop working, I would have to shake it to get it to work again. Replaced with a different air pump.

Amazing little air pump. Super quiet and affordable. I guess the quality control is bit hit and miss based on the reviews. I must have gotten lucky because mine finally died after being plugged in for 5 years 24/7.

I could sleep peacefully now.

Been running like a champ for almost a month now with no issues so far.

A tiny bit noisy but works fine. If you want to lower the air pressure get an air control valve.

Value for money Working fine
