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

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.

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.

Only lasted 7 months before dying. Which is disappointing since the one I bought previously lasted longer.

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.

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.

Great for on the go if you have a power bank and temporary installation. I would not suggest it for a large aquarium or anything over a 7 gallon bucket. Low power for air flow so you may need more than one if there is a lot of bait. Almost no noticeable noise.

I used this to transport my goldfish in a gallon of water for a 6 hour car ride. It is an excellent pump, could definitely be used in a larger volume of water.

I have three small tanks that I use these with and they work great. I bought the first one three years ago and it just a few days ago wore out. Three years for a mini pump that worked every single day 24-7 is not bad. They work great and they last a long time. And their very small size makes them very convenient and unobtrusive.

Have many tanks and air bubblers, most rattle/vibrate off there position without securing and buzz all night. Bought this one for a quick start brine shrimp hatchery… was expecting a sub par week air flow, not so. It’s as powerful as my +$50 models managing balanced, and silent air flow. The included carabiner is quite handy as well keeping it off a surface. Air stone works perfectly with included 4’ of flexible line. Usb power availability does affect performance… mine was plugged into a 2.1 amp 5v (12 watts) represented in video, but was too much, so replaced 1 amp (5 watts) and halfs the output to what I needed; may last longer too. Still has to pinch air line to slow a bit. It’s an all in one high performing unit at a fraction of the price, new go to. (Has been running 7 days before review, no issues)

Great product specially for smaller aquarium or bowl type aquarium.

コスパ最高 静音性が特に良い

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.
