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.
