Review on KEDSUM Battery Aquarium Air Pump: Ultra-Quiet Rechargeable Fish Aerator with Dual Outlets - Ideal for Fish Tanks, Outdoor Fishing, Fish Transportation, and Power Outages by Damon Murray

Ordered one of these bad boys last week, and let me tell you, it is worth every penny. It's super useful if you're power goes out and need aeration to your tanks. The main reason why I bought this was for my mini 15 gallon outdoor pond. The summer heat has been pretty bad, so I thought my babes in the pond could use the extra oxygen. Super easy to use, 2 second press turns it on continuously, another short press turns it off and on every 10 seconds ( this is how it could last for up to 20 hours ) and third press turns it off. The charging takes about 5 or 6 hours, so I charge it when I'm asleep, then start it up when I wake up. It's not loud at all and it produces a great amount of bubbles, but not to the point where it's too much. Definitely a great buy and I will be buying another one once I start building another pond.
