Review on 🐠 Mini Aquarium Air Pump USB 5V by Useekoo - Ideal for Aquarium, Fish Tank, Fishing with Air Stone and Silicone Tube by Dominic Maxwell

As soon as I saw them on YouTube I knew I had to buy them but I kept putting it off because I really didn't need them until a small tornado in my area cut off our power for a week interrupted. Keeping the water moving and filtering is very important when you have a power outage or are transporting fish. They work great with these USB batteries, I have several of these and they had enough power to hurl an air stone at the bottom of my 75 gallons which really impressed me, these things barely vibrate when you plug them in but they do vibrate . Great job, you could even use it as your main pump if you don't make a mistake with it.
