Aquarium Air Pump with 35-Hour Battery Backup

Dual Outlet USB Rechargeable Aquarium Air Pump – With Battery Backup

This dual outlet aquarium air pump delivers dependable aeration for small to medium tanks and serves as a critical backup during power outages. With a flow rate of 3.0 L/min and two independent outlets, it easily runs multiple tanks or split air lines.

We use these extensively in our nursery. They have been reliable and they are very quiet. The built-in rechargeable battery provides up to 35 hours of runtime and switches automatically to battery mode when power is lost. Choose between constant or intermittent (10s on / 10s off) modes for extended use.
