Review on 🐠 Mylivell Quiet USB Air Pump for Fish Tank - Ultra Silent, High Energy Saving Oxygen Air Pump with Air Stone and Silicone Tube by Angela Stephenson

Absolutely cool baited bubbler. Compact, rubber coated, USB powered. Plug it into a power adapter or flash drive and you're done. This setup also fits an 8 inch hole to keep it cool. The hose is not the biggest and breaks. But if you bend it too sharply, it's workable. Also comes with a nice stone and a check valve and is much quieter than standard Dcell bubblers. The included plastic mount and suction cup didn't work for my application, but I think they will work for a small aquarium. But it is by no means a large volume. I would say 10 gallons max. But in terms of portability, this is the best option. It's best to stop buying D-cell batteries.
