Petbank Aquarium Air Pump with Dual Outlet - Portable Fish Tank Air Pump with Air Stones, Quiet Aquarium Bubbler 1.5-2L/min²Two Power Supply Modes, Ideal for Aquarium, Fishing and Power Outage

I bought this for my Fluval 13.5 gal. It's perfect. I don't have to worry about storms coming and knocking out power when I am at work. This product delivers oxygen automatically when the power is cut off. The battery range is pretty impressive. I will say it's noisy but simply moving it around to find the sweet spot helps with that.

The media could not be loaded.  These air pumps are the best air pumps i have ever owned.. you can use it plugged in and if the power goes out, it'll automatically kick the battery power on and keep your fish oxygenated! This has saved everyone of my fish tanks from suffocation, I have had the power go out 2 times since I got them a few weeks back. The charge lasted 8 hours with 2 bars left so it realistically could have lasted a 3+ hours longer without another charge. Don think about it, just order it. My husband hates me spending money on fish tank stuff but he was very insistent about getting one for every fish tank we own after we received the first one. Now we have 3 and have had absolutely no issues with it. I just got some shrimps in the mail and they are drip acclimating right now using the air pump, I love it! Just hit that add to cart button and send it, you won't regret it 😉

If you're looking at air pumps for your aquarium, definitely buy the pumps that will switch over when the power goes out like this one does. It will save your fish if you loose power for any length of time. It has two modes - one where it pulses and turns on and off to save battery power, and one where it runs continually. On the continual mode, it will easily run 24 hours without being plugged in which is far better than any other I tried. It isn't the quietest, but it isn't annoyingly loud either.

Works great for my minnow bucket . Best part is , no more damn d-batteries

Used for keeping rock crabs alive. It works. Easily keeps two 5 gallon buckets aerated, confident that it will aerate a medium or large cooler. I liked not having to purchase batteries and not having it constantly plugged in. Run time on batteries alone is greater than 20 hours. Love the included check valves. Would have preferred the valves be internally mounted instead of externally inline, but they work fine. With the check valves in place, aerators lifespan should be equivalent to the lithium ion batteries.

I bought this becasue we have been having power outages recently and I will be out of the country so I wanted to make sure my 29 Gallon aquarium has enough power to run my sponge filter. This little pump fit the budget and it is super powerful, much more powerful than my older pump. The hose that came with it feels cheap but for a decent battery powered aquarium pump under 50.00 what can you expect. My only complaint is the clip on the back vibrates on the table so you might have to bend it back so that way it does not vibrate, very impressed with this pump.

No hace un ruido insoportable y cuando hay cortes de energía eléctrica sigue funcionando por un largo tiempo 🥰

Well, power finally went out unfortunately and this pump kicked right on. I can not comment on the long term as that was a short-lived outage. I will say that I had bought another brand for my other tank and it did not do a thing, and it was tested several times and worked, just not when I needed it. Ordering another Petland today.

Fabrication soignée, tient facilement une journée de pêche une fois rechargé et les leds indiquent en permanence l'état de charge de la batterie. Le fonctionnement en intermittence permet aussi d'économiser la batterie.

Rien a redire. Autonomie correct (+/- 20h) mais peut être utilisé branché sur secteur et en même temps elle se recharge parfaitement, donc le top.

Tout simplement parfait, je conseil au top, fait un peut de bruits, mais raisonnable, fonctionne très bien.

Ran throughout a planned power cut. My only con is the only pressure control is a needle valve and intermittent mode. Power control would have been nice.

Been running for three months now. It’s done better than a lot of other 12 volt usb air pumps I’ve had.
