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
