KEDSUMAquarium Air Pump, USB Rechargeable Fish Aerator Pump with Accessories for 5-120 Gallons, Portable Fish Tank Bubbler, Used for Outdoor-Fishing, Power Outages and Emergency

I am new to the fish tank game, but this pump is great! It is super quiet, small and sleek, and so far has been better than I was expecting. Fish seem to love it, super easy installation and set up. I highly recommend.

Very strong with plenty of tubing and nice air stones that I decided to keep in my tank after I moved to another state.It kept my fish & aquatic plants safe and alive in a 5 gallon bucket for 3 days, being charged once during the second day. It's not noisy and has a clip to attach to the side of a bucket. It works great and will come in handy if the power goes out. Worth it!

Works great and has a long lasting charge.

Seems to work great for me. I left it plugged into the charger all night and it kept my bait alive nd still had a full charge the next morning, ready to go fishing. Unit is NOT well sealed from water intrusion. I had it out on the pier for 6+ hours and it still was going well. You can see the green light on the front, even in daylight pretty well, so you know it is working. You can barely hear this thing in a quiet environment, it is almost silent. On another day, when it got low on charge, it went into some intermittent mode where it would run for a few seconds, than stay off for 10 seconds or so, at least until it finally died later. Seems useful, and will save me money on D batteries for my bait pump. Edit: not great for saltwater bait pump use. I was relatively careful with it, then it gave up the ghost within a few days. NOT sealed at all, so any drop of salt water will get into it and ruin the electronics. Tried to clean and dry it out, then the charging port quit working. Great for clean and dry environments only.

Works great

Barely used it 3 or 4 times and it’s starting to malfunction. It turns itself on after unplugging from the charger, which is not a big deal, but then I can’t turn it off. Despite the button audibly being clicked repeatedly, the aerator does not respond and will continue operating until the battery dies.

If you keep aquariums this is a must have for each tank to keep your fish safe in the event of a power outage. These are recharable and have a considerable battery life. I can't count how many times I've used these when the power has gone out to keep the oxygen flowing for my fish. The best thing is these stay on automatically if they're already in use and plugged in. They will stay on when power goes out. These are also great to have when transporting fish to keep them oxygenated in the car or just out of their tank during maintenance.

I am glad I bought two as the charges didn't last nearly long enough as described.... We were in a hurricane and lost power. Even in intermittent bubbles stage they went through the batteries in about six hours each. Had to keep charging them, but they took forever to charge and thus there were periods when my aquarium had no movement. One fish died, but the others made it. I think I need to get 2 more jn order to ensure a steady supply of bubbles. (And a generator.....) Thinking these would be great in a bait bucket for fishing though!I had no problems with the functionality and sturdiness of the pump. Kept changing the pumps out and used the same air tubes.... and the connections remain intact. I also have no issues with noise? Even the sound of engagement on the intermittent level was muted.... and the aquarium is in our bedroom. Not a heavy device and the air flow produces lots of bubbles and I like the appearance much better than my electric powered sponge bubbler.All in all.... I recommend.
