I moved from California to Ohio with a betta, 2 albino bristlenose plecos, and 4 bumblebee gobies. They all hung out in a plastic storage tote with a lid for 4 days. I had both airstones going inside the tote the entire time and I did large water changes with prime every night.This pump has a usb type charger so at night it would be plugged into the wall to charge up but in the car, it ran on battery. I drove for minimum 12 hours a day and the pump would get to one green circle after about 8 hours. At that point, I would just plug the usb into my adapter in the car so it wouldn't die.This is the quietest pump I have ever seen! I would often check it in the car because I just couldn't hear it and worried it had cut off. The only time it made noise was when my dog's metal food bowl got pushed against it.Now that I am at my new home, as you can see in the video, I continue to use it for both 5g tanks. One airstone for each tank. My fish are super happy.If there is ever a power outage, I know that they'll be good for awhile because it will automatically switch to battery mode.I plan to purchase another pump when I get my 40g tank set up. The price is also extremely reasonable for how amazing this product is.All in all-- HIGHLY recommend

This is a decent air pump for your aquarium or however you would like to use it. I never ran it until the battery was completely dead, however it did last for a few hours when I was testing it. I damaged one after about a year and a half of service because my one-way valve malfunctioned with a new tank I set up and water got into the pump/motor. So it was completely my fault just be sure to use a one way valve/ backflow preventer. I also like that is a low-voltage device I also like that as a low-voltage device with a USB plug whereas you could use a phone just pack to power in the event you have extended power outage. Are use mine one time to travel about an hour and a half away to buy some fish from someone online and I was able to plug it into a USB adapter in my car.

I was very leery of ordering this inexpensive device; because my husband and I needed to transport Koi ! We needed to move them 40 miles.This little gem did the trick! We were so confident after the first use that we moved multiple Koi over several days in a row and did not lose any fish!So easy and quick to set up and use. We did charge the unit overnight before the first use.

Works great. I was able to drop one airstone in each of my two containers when moving. Plug into your auto usb port. I didnt realize at first that the pump is actually rechargable so you don't need to kerp it plugged into the power source.

I haven’t gotten much use out of it. I was disappointed at first because I thought one of the air hoses wasn’t working. It turned out to be the bubbler on the end. I just need a bubbler that isn’t plugged. I did contact the seller. They wanted a video of it. I don’t know how to do that. I’m glad it is working!! I wanted to wait to write a review. It is doing a good job now that I figured out what was wrong.

This thing works great! Use it for ice fishing and keeping my 5 gal pail bait bucket aerated. Very powerful and lasted all day on constant aeration even at 10 degrees! Very impressed for the money. On the bait bucket it doesn’t matter but if you were using inside or something it is a bit loud. Would buy again!

went to use it for its intended use and DOA. got some new fish in and wanted to hold them for a day before placing in community aquarium. nod'da; nothin'; no AIR. PAST RETURN DATE (8/26/2020) NOW 9/2/2020. OH WELL!!!!

Had a scheduled 9 hour power outage and these pumps worked the whole time. I charged them the night before, and they lasted the whole nine hours with charge to spare.
