Essential mode saves power
During an outage, circulation and aeration may be prioritized over lights or heaters depending on the tank.
Specialized runtime calculator
Aquarium Power Station Runtime Calculator
Estimate aquarium backup runtime for all equipment or essential circulation and aeration only.
Aquarium backup is outage-oriented. This calculator compares all equipment with an essential-only setup, but it does not guarantee animal safety.

Aquarium Power Station Runtime Calculator FAQ
Should I power aquarium lights during an outage?
Usually lights are less important than circulation, aeration, and temperature, but needs vary by aquarium.
Why include essential-only runtime?
It shows how much longer a battery may last if you run only the most important equipment.
Accuracy notes
This calculator estimates electrical runtime and sizing. Actual results can change with device model, load variation, battery age, temperature, inverter idle draw, charge level, reserve settings, and manufacturer limits. Verify safety-critical loads with the device and power station documentation.
