Aquarium Air Pump Quiet High Output Air Aerator for Fish Tank 4 Air Valves Stones/Tubes Check Valves. (Saltwater)

This is incredible! We are on the road traveling in our RV and our fancy goldfish. They Live in a 20 gallon hexagon acrylic tank. We live off solar power and I charge this with my goalzero yeti battery pack and it takes over when the power source is turned off. Its super simple red light it has power running the pump or green light means it is on the battery. My fish are never without their bubble stones going. This set up allows me enough power off the solar battery to run their filter. Running a normal plug in air pump would drain the main battery so quickly. This pump has been running for a month now 24/7 with zero issues.It has 2 air ports but I am only using 1 of the ports.

Seems to be working properly after a few days use; however time will tell; as with the last purchase of a similar 5 volt usb aerator purchased left plugged in over night as instructions read that it would be ok; just to find it burned out after 24 hrs use; so, I suggest do not! leave charger plugged into wall socket & pump after full charge; unplug when red light flashes!

My husband loves this. He no longer has to worry about batteries and this literally will last all day long. We used it in our aquarium when our power went out and it was still running after 7 hours.The main purpose this was purchased though was bait. You can take a rechargeable battery with for extra coverage but odds are you won't even need it.Not only does it run, you can tell it is very high quality. It is definitely made to hold up.Lastly, a great thing about this, if the power goes out it automatically kicks on. Making it ideal for a backup source if needed.

I bought 3 of these and they work great! Strong dual air producing pumps 2 for the 180 gallon and 1 for the 100 gallon. I love that they work during power outages. It's been months and they are still going strong. Gives me a peace of mind knowing I'll have some to my tanks when our outages hit like clockwork. I did replace the cords with longer cords to reach the power area. I'll be ordering 2 more just as backups.

I used this air pump when I moved halfway across the country with about a dozen corydoras in a 5 gal bucket. I found the pump reasonably quiet, I brought them into the hotel room with me and wasn't bothered by it at all as it ran all night. All my corydoras made it safe and sound along with a few hitchhiker cherry shrimp to their new home.

Yeah. You know I have 4 of these going. I like them. As far as noise level. They’re right in the middle. They’re not loud but they’re not quiet either.I can’t sleep if it’s too quiet, that’s just me. But it gives me piece of mine when I’m away. These will kick in. We don’t get many black outs where I live. The one time the power did go out, it was less than an hour and these pumps kicked in. I have them running with sponge filters too. Always have a back up guys. Your HOB or canister can go out. It’s just a matter of when.I approve of these air pumps. 👍🏼

I bought this portable oxygen pump to sustain my 35 gallon-fish tank during a power outage, and I'm pleased with its performance thus far (we got our power back after an hour). It has two outputs so I was able to put both tubing and aerator on each side of the fish tank and they created ample circulation in the water. I'm grateful to have something that can be charged in multiple ways too. Only time will tell how well this machine will work on longer outages; until then, I'm glad I have a back-up.

used for vacation saltwater fishing and abused it with saltwater and sand. Lasted about 12 hours on a charge. came with everything needed. easy recharge. pretty good bubble flow. Kept bait fish alive in 5 gallon bucket all day. Used electric aquarium bubbler overnight while this recharged and then just plugged this one back in in the morning. ready to go without having to go for bait before going fishing. Excellent product for the week that I needed it. Can't speak to how long it will last but for the money it was good for the week.
