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

This is the best, most powerful pump (portable or not) you can buy! For such a compact size, this pump outperforms many larger replacement pumps. You will be surprised! I bought 6 pumps as a last resort because we were upgrading our electrical panel and the power was out for 8 hours. We have (2) 29 gallon and (1) 75 gallon tanks. I ended up only using 4 of the 6 pumps because the 29 gallon tanks only needed 1 pump each due to the incredible pressure the pumps exerted. See how long they last on my 10,000mah USB power bank. Each of the tanks was powered by Anker's own 10,000mAh battery: just 50% less in 24 hours for both tanks. Just great! The icing on the cake, the rather large air stone they supply released tiny air bubbles after 12 hours which oxygenated the tanks causing the oxygen bubbles to form on the leaves of the plants in the tanks. The pumps work so well I decided to replace the old pump on the 4 seat chamber for (2) 3 gallon feed tanks with a portable pump powered by an old 1w iphone usb box is driven; just to see what's going on. I had to bleed some air from one of the valves because the pressure was too high for the small aerostones in the (2) 3 gallon tanks. The small USB pump has been running on a 1 watt Apple device for almost 3 weeks now. I highly recommend this USB pump. It's definitely worth the price and delivers great performance. I'm glad I found this little pump here at Revain.
