Dual Output | Battery Powered | Silent

Cobalt USB Powered air pumps use a 5V DC powered motor that also has an onboard battery that can last up to 24 hours without a direct connection to a power supply. It can run continuously or with a 10-second on/off cycle in the battery powered mode to make the pump last as long as possible. Power outages will usually last just a couple hours, but you never know when disaster could strike and have an outage for a few days. When your aquarium water goes without flow, O2 levels will start to drop and after a few hours, the lack of oxygen could start to cause serious issues for your fish. By just dropping an airline with a diffusion stone into your display tank creating some surface movement will help promote gas exchange, keeping the oxygen levels from depleting.

Product Questions

I like the sound of these devices from cobalt aquatics, and this one in particular because of the dual output. Being able to extend the range by connecting it to a usb power brick is fantastic (and brilliant on their part). How does one go about determining how many of these should be used for their size tank and bioload? If I have a 160g tank that is heavily stocked. Will this provide adequate oxygen for the 24 hours it says it can run for or should I have more than one unit? and if so how many?

I talked to the guys here and we think you will need at least two of these to get the proper surface movement in this tank.
