Power Station Runtime Calculator
Select the devices you need to run, pick a duration, and get a recommended battery size — computed live from this project's 20-entity verified dataset.
1. Select Your Devices
2. How Long Do You Need Power?
This is a general power-math guide, not medical advice. Confirm exact power requirements with your device manufacturer or DME provider before relying on any backup power plan.
3. Matching Power Stations
Select at least one device and a duration to see results.
Methodology: total wattage × hours ÷ 0.75 AC-inverter efficiency factor × 1.10 safety margin = recommended Wh. Devices marked ⚕️ require a confirmed pure sine wave inverter — units with an unconfirmed or non-pure-sine-wave inverter are excluded automatically, not just deprioritized.
