- 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
