Plan Emergency Backup System
How long do you need backup power? (24h = 1 day, 72h = 3 days)
Select Critical Devices
Choose devices you need to keep running during a power outage
How Emergency Backup is Calculated
Total Wh Formula: Sum of (Device Watts × Hours × Quantity)
Recommended Capacity: Total Wh × 1.25 (25% safety margin)
Output Wattage: Sum of all devices running simultaneously
The 25% buffer ensures you have enough power even with efficiency losses and ensures the battery isn't fully depleted (which shortens battery life).
Important Safety Notes
- Medical devices: If you depend on life-critical medical equipment, consult with your doctor and power company about backup solutions
- Carbon monoxide: NEVER run gas generators indoors or in garages - they produce deadly carbon monoxide
- Refrigerated medicine: Ensure critical medications stay at proper temperature
- Water supply: If you have a well pump, factor in its power requirements
- Heating/cooling: Space heaters and AC units use significant power - consider alternatives
- Battery maintenance: Keep your backup system charged and test it quarterly
Emergency Preparedness Tips
- Keep it charged: Maintain your power station at 50-80% charge when not in use
- Solar backup: Pair with solar panels to recharge during extended outages
- Prioritize devices: Start with most critical (medical, fridge) and add others as capacity allows
- LED lights only: Use LED bulbs (10W) instead of incandescent (60W+)
- Minimize fridge opening: A closed fridge stays cold for 4 hours, freezer for 24-48 hours
- Have a plan: Know which devices to power first and practice using your system
