Power outages don't just stop filtration—they can reduce oxygen levels and, during the warmer months, allow aquarium temperatures to rise.

Pair this backup power bank with compatible USB-powered emergency equipment to help protect your aquarium when every minute counts.

Recommended accessories include:

• USB Aquarium Air Pump – Helps maintain oxygen levels during power outages.

• USB Water Circulation Pump – Maintains water movement and improves gas exchange.

• USB Aquarium Cooling Fan – Helps promote evaporative cooling during hot summer power outages when elevated room temperatures can increase aquarium water temperature.*

Together, these emergency essentials help provide additional peace of mind while waiting for power to be restored.

*Cooling performance depends on room temperature, humidity, aquarium size, and fan placement.
