Mini Aquarium Air Pump Outdoor Quietest USB Air Pump for Fish Tank with Air Stone & Silicone Tube Small No-Charger Oxygen Pump for Aquarium Silent Aquarium Air Pump, Blue

Super convenient for outside fishing. Before I bought this mini aquarium air pump, I was a little worried about the air flow and the sound when it works. To my great surprise, this usb air pump does a really great job. It adds much oxygen to my fish tank. You can see many mini water bubbles, the little fishes swim so happily. Besides, I am interested in fishing outside, in order to make the fish that i had caught alive, I need a oxygen pump to bring outside, but traditionally, many air pump just can be used for fish tank inside. But this usb aquarium air pump has a MICRO USB power line and can be brought outside, you can just take a Portable source. And the air pump is very mini, so it can be brought conveniently. I really like this mini aquarium air pump. the price is good. Anyway, I like it so much, I just want to share this good product with those who love keeping fish or fishing outside. It is worthy.

This little pump was amazing for my fishy friend! The instructions were in a different language ,but it's self explanatory. This is amazing for a one to two fish tank to provide a little extra oxygen for them. It's very quiet and small it comes with a long tube so I ended up cutting mine in half. I wouldn't recommend keeping it on constantly ,but rather turning it on a few times a day for an hour or so.

Before buying this fishing air pump, I have scanned many other pumps and reviews. I must find a perfect oxygen pump for my little fishes which were sent from my best friend as birthday gift. honestly speaking, I was a little worried about this mini aquarium air pump. But to my surprise, it was really effective and did a great work. the flow of water was amazing, you can see many bubbles in the fish tank. everyday, I can see my fishes swim in the water happily, it so cool. Also it is very quiet, I can do my own thing without noise. It's definitely worthy of purchasing, good price, high quality. Bringing a portable source, I can also use it when fishing outside.

I'm using this to power a tiny air filter in my 2 gallon desk bowl at work. It's quiet enough that my coworkers don't notice it, though it does create a little hum (to be expected). I also dig the shape, it doesn't look out of place sitting next to the tank on my desk. Check plus.

This is a great little emergency aerator, uses a USB port so can be used on several battery types if electric goes out.

The particular unit I received did not seem to have a solid connection at the pump (micro-USB; the other end seemed fine). It required you to push hard and wiggle around to get the pump to turn on, and the output and noise varied depending on how you wiggled. It would usually lose the connection after being placed on a surface. It was also surprisingly loud considering it's small size and being advertised as the "Quietest USB Air Pump". Returned immediately.

Worked loudly for a day. Messed around with different surfaces to place on. Was fine. Stone stopped working within a week.

Good
