AquaMiracle Lithium Battery Powered Portable Aquarium Air Pump for Fish Tank, USB Rechargeable Aquarium Bubbler Aerator for Outdoor Fishing, Power Outages and Emergency

This review is unique in the fact that it's not based on immediate experience. I have had my pump for I think about 2 years now. I bought it for fishing, to keep my minnows aerated. I was just out ice fishing, so even in the cold, this pump ran for approximately 8 hours and only used half it's battery life! Plenty of power to run one stone, charges quickly, and last all day on one charge! WELL WORTH THE MONEY!

The media could not be loaded. I purchased three of these AquaMiracle USB battery backup bubblers for my reef tanks about a week before Hurricane Milton hit last fall. I was within 10 miles of the eyewall and lost power for over a week. These bubblers stayed plugged in and running, and when the power went out, they automatically switched to battery mode, lasting around two days.I had my generator up and running within 18 hours, but these bubblers kept everything alive until I could safely power my tanks. I didn’t lose a single fish, invert, or coral. Since then, I’ve left them running full-time as an extra layer of protection.Highly recommend this as a failsafe for any power outage!

Update 2024:After seeing my original review the manufacturer contacted me offering a replacement in 2023 . I did not see their Amazon message followup to me right away so the late update.The replacement arrived super fast. Which was very good customer service .The replacement seems to be charging and so far the tubes are staying attached . So i bumped up the stars.————————————————————-I bought this exact model several months ago.It still is running great. So i decided it would be nice to have one to swap out while the other one charges.I setup this one up exactly the same way with the tubing , stones, and check valves.Within a few hours of use, both tubes fell off the main body. I put them back on and than tubes kept falling off of the stones, check valves on both its ends no matter if the tubing was shoved up as high as they would go.It has been a battle trying to keep the tubes attached to the main body , check valves or stones . Something that never and still has never happened with the first one I bought.The little black main body stems even left black on the clear tubing when they fell off . The main body stems are black and very short . See picture.Besides gluing them on, I have no idea how to keep these working like my first one.If you get one like my first one it is 5 stars but if you get one like my recent purchase it is a zero for being able to aerate your fish with confidence. .Update: 10/11/23.I ended up zip tying all the plastic tubing and check valves on even than they would slowly walk off the check valves and stones…Well this lemon finally refused to recharge. The battery life got worse and worse from day one. Even leaving it plugged in to a USB powerbank , it just will not run. Really sad how this newer purchase was a total ZERO in quality vs the one i bought over a year ago is still working great. Sad that i paid way more for this one than the older one. I keep seeing it being offered for 50% of what I paid for my lemon , but I Wont be buying this brand again.

Works great, very quite and lots of bubbles.

Bubbler works great, hard to tell what setting it’s on but honestly it works awesome. Works while connected to a battery pack, on a full charge will run for most of the day. Lasted over night for me when I had a bunch of left over shiners. Nice and quiet. Definitely a better choice than all the other bubblers I have ran through.

About every 3-4 months, this pump would just randomly stop working. I have mostly kept it plugged in, and only used it on battery mode once or twice, but every few months I would come into my fish room and find the pump off. I would push the power button and it would start right up, but then it would do it again then next day. Then, it would work flawlessly for another few months until it would shut itself off again.Then a few days ago it did again, only now it can’t stay on longer than a few hours, and if I unplug it and try to run it on battery it won’t work at all. The charge meter shows the battery is full, but nothing happens when it isn’t plugged in. Totally dead.Sorry, can’t recommend this pump to anyone.

Keeps bubbles so fish will live during outage use one and charge the otherkerp switching

This thing is awesome. I have three of them. The charge lasts about 6 hours on high. It is super light and it will still run while charging. I use them to keep bait alive while I am fishing. They are also more reliable and durable than the old D battery aerators.
