What matters in which emergency

Prep isn't one list. Pick an emergency to see what's critical, what helps and what can wait.

Power outage, 1 to 3 days. Storm, heat wave or grid failure knocks out power. Water and stores mostly still work.

Critical

  • Phone power banksYour phone is your map, flashlight, radio and alert system. A charged bank keeps it alive for days.Power stations and generators
  • Headlamps and batteriesHands-free light is the difference between handling a dark house and tripping through it.Lighting and staying warm
  • Battery CO alarmGenerators, heaters and stoves used during outages are a leading cause of carbon monoxide deaths.Power stations and generators

Important

  • Stored drinking waterYou can last weeks without food but about three days without water. Mains break in quakes and pumps stop in outages.Water storage and filters
  • No-cook shelf-stable foodGrocery shelves empty within a day of a big warning. Food you can eat cold works in every scenario.Emergency food and cooking
  • Power station or generatorKeeps a fridge, CPAP, router or medical device running. Most valuable for long outages.Power stations and generators
  • NOAA weather / crank radioWorks when cell towers and internet fail. Official alerts and evacuation orders still reach you.Radios and communication

  • Stocked first-aid kitWhen 911 is overloaded, minor cuts and burns become your problem to handle well.First aid and medical
  • Prescription reservePharmacies close or run out. A two-week buffer of essential meds is one of the highest-value preps there is.First aid and medical
