Short answer: A resilient household outage plan protects people first, then water, food safety, information and only the electrical loads that are genuinely essential. Backup power is one layer of the plan, not the plan itself.
Generator locationCDC says portable generators should be outdoors at least 20 feet from doors, windows and vents.
RefrigeratorUSDA says an unopened refrigerator keeps food cold for about 4 hours.
Full freezerAbout 48 hours if kept closed; about 24 hours when half full.

Add household-specific items

Prescription medicines, infant supplies, pet needs, mobility aids, hearing-device batteries and electrically powered medical equipment can matter more than generic emergency gear. Build the kit around the people who will actually use it.

Store the kit where an outage actually happens

Flashlights buried in a garage cabinet are less useful when the lights fail at night. Keep immediate-use lighting accessible in bedrooms and common areas, then maintain a larger household kit in a known location. Avoid relying on a phone flashlight as the only light source because the phone may also be needed for alerts and communication.

Label batteries, cables and adapters so anyone in the household can use them. Test rechargeable items periodically and replace damaged or swollen batteries according to manufacturer and local disposal guidance.
