AQQA Aquarium Rechargeable Air Pump,Multifunctional Portable Energy Saving Power Quiet Oxygen Pump, One/Dual Outlets with Air Stone,Suitable for Indoors Power Outages Fishing

I bought 3 of the mid power pumps a little over a year ago to use in my 3 tanks. I have a 55g, 120g and a 125 gallon. I use them all as daily pumps and they have worked well during a couple of power outages to keep oxygen flowing in the tanking. They just work like regular pumps and are very quiet, and when an outage happens they switch to battery mode automatically. The pump on my 125g went out shortly after the 1 year warranty, so I replaced it with the most powerful unit. The first one I received was extremely loud and I thought it might have been because of the power, but I exchanged it for a new one and it was just a bad unit. The new unit is very quiet and quite powerful. Hopefully it lasts longer than 1 year, but if not, they are priced affordably.

This was a lifesaver, literally, on the long (2+hrs) move to our new home. I would move it back and forth between the large buckets that my fish were in during transporting, and it worked wonderfully! I was very worried about how the fish would handle the long move, but this really helped a lot. And now that we are done with moving, I have it if I need a battery back-up in case of a power outage, which again would be a life saving event. I have freshwater angel fish that I've raised since they were very young and I am very attached to them, as I am all of my babies. I always get comments on how large they are and people always seem shocked by their size, so I take some pride in knowing that I've done well with raising them. The pump is small enough that it won't be in the way, or be unsightly while using, and it's powerful enough that it will help keep your fish alive over long periods without electricity. I am very thankful that it worked so well for our move. And I still have it to use as a failsafe in case of power outages. If you really care about your fish, as I do, I would definitely recommend having at least one, probably a couple depending on tank size and how many fish and their size. I am planning on getting at least 2 more to use as backups for my 55 gallon tank. I highly recommend this pump for anyone needing to have a battery backup pump for their tanks.

The media could not be loaded. The device is super quiet. If you use the setup that comes with the device, you’ll see that it is highly efficient. At the time of video recording, the device had been running for about 10 hours on battery, and the battery level was still in the 90-100% range. I would highly recommend this to anyone planning to use it with the setup shown in the video

I would rate this a 5, but a few, very minor things.Pros:Battery life so far is excellent and is easy to charge or leave plugged inPlenty of surface agitation for a 10 gallon tankPlenty of tubing is included and the air stone included is perfect for what I need it forCons:The Amazon site has the same description for 3 different sizes.The smallest one only operates1 stone but the description says 2.It is not loud but vibrates heavily, my fish freaked out if it was placed on the same table or attached to the tankThere is no included check valve with the smallest pump. So if the pump will be below the water level make sure to buy one.I know the information is there if you dig below the surface, so I can't fault the company on my lack of research, but this is to help anyone else that needs some clarification.

I really like this air pump! My 2.5 gal shrimp tank wasn't getting enough surface agitation therefore had low oxygen levels which I needed to fix. I had a dilemma though since is the tank is on my bedroom dresser where there’s zero actual outlets so I’ve got a surge protector run from another wall but all the real outlets in it were already in use. It did however have a usb port open so I hit the jackpot when I found this rechargeable pump!It took mere minutes to setup, is small enough to fit in limited space & really quiet. I can’t even hear it versus the actual air stone bubbling & my floor fan. I normally can’t stand any light source while sleeping but the blue light faces up at my ceiling slightly lighting up the pitch black. I oddly found it soothing & had zero negative effects on my sleep, although I may tape over the lights no big deal to do.I used a different air stone then the one it came with just because my shrimp playground has little available floor space so I got one that suctions to the tank wall but the one it came with would work perfectly fine! This kit could use a backflow valve & flow adjuster but my other one came with that so worked for me but something to consider.I’m in Florida so should we have a bad storm I feel at ease knowing my shrimps will have air to get through it. Honestly I’m so impressed with it I’ve ordered two more units for my 5 gal betta tanks :)

Been having trouble keeping the air pump continuously running. LESS than 6 months since I purchased and started using the air pump, and now I will likely NEED to get a better REPLACEMENT.I would have the air pump plugged in during the morning with all the charging bars full. Later in the evening or night the bars would be at 1 or 2 bars while the charging cable still plugged in. I then have to remove the cable and plug it back into the air pump charging port for the charging bar to show the “charging in progress” status.Many times my tank would be out of oxygen created by the air pump, throughout a portion of the day and other times the entire night while I’m asleep. This is VERY CONCERNING.The battery power seems to be reduced, but not significantly to me. The battery doesn’t last after being plugged in and charging while turned on at the same time. Not sure if the battery will last if I charge the pump without using it, but either way that will defeat the purpose of having an ongoing pump.Although the air pump is pretty quiet compared to many others I’ve tried with the similar power, it still makes a good amount of noise unless it’s placed about at least 3 feet away in another room at night when everything else is quiet.At first the pump was the best value for money, design, meets the needs for the amount of air flow I need.
