A power outage kit has one job: make the first hours safer and less chaotic. It should help you see, drink, eat, stay informed, protect health needs, and decide whether home remains a safe place to stay. Start with those jobs, then build around the people and systems in your own home.
Start here
Build the kit in this order.
- Water and food. Store what you can use without electricity or frequent trips to the store.
- Safe light and phone power. Make it easy to move, get alerts, and contact people.
- Health and temperature needs. Plan for medicine, medical equipment, infants, pets, and weather.
- Information and household decisions. Keep a radio, contacts, and a simple plan where everyone can find them.
Start with the problems an outage actually creates.
Before buying anything, walk through one ordinary evening with the electricity off. Which rooms become unsafe to cross? Does the water still run if a pump loses power? Can anyone take needed medicine, keep it cold, or use essential equipment? Can you open the garage, cook safely, hear alerts, and contact the person who should know you are okay?
This makes the kit personal without making it complicated. A small apartment may need portable light, water, a power bank, food that needs no cooking, and a way to leave if indoor conditions become unsafe. A house with a well, garage door, sump pump, or refrigerated medicine has more dependencies to think through. The CDC’s power-source checklist is useful because it includes the less-obvious items: appliance thermometers, battery-backed alarms, backup power for medical needs, and warm layers.
Put the first group of supplies in one known place. A kit that is spread between a closet, a drawer, and the trunk is harder to use at 2 a.m. than a simpler kit you can reach in the dark. You do not need matching bins or survival-themed packaging. A sturdy tote, cupboard shelf, or labeled spot near the exit is enough.
Keep water and food that do not depend on the grid.
Water deserves the first space in the kit. Ready.gov recommends at least one gallon per person per day, with a basic supply intended to last several days. That is a starting point, not a promise that every home has identical needs. Add water for pets, hot weather, sanitation, or a household where a loss of electricity also means a loss of running water.
Choose shelf-stable food that your household already eats. Canned beans, soups, fish, fruit, nut butter, crackers, shelf-stable milk, and familiar snacks are more useful than a drawer of expensive food no one wants. Keep a manual can opener beside the food, not somewhere you will be searching for it. Rotate supplies into normal meals before they expire, then replace them. The goal is a quiet routine, not a museum of untouched cans.
Include a cooler, ice packs, and refrigerator and freezer thermometers. They give you options if the outage lasts and food or medicine needs careful attention. During an outage, keep refrigerator and freezer doors closed as much as possible. For the decision after the power returns, use FoodSafety.gov’s food-safety chart instead of tasting food or trusting how it looks.

Make light, power, and information easy to reach.
Put a flashlight or battery lantern where you can reach it from bed, another near the main living space, and one near the kit. Headlamps are useful when you need both hands. Keep the batteries with the light, and test both before you need them. The Red Cross recommends flashlights rather than candles during an outage because an open flame becomes one more risk in a dark, distracted household.
A charged power bank, phone cables, and a car charger can keep a phone useful for alerts, messages, maps, and emergency calls. Keep a battery-powered or hand-crank radio for weather information when cellular service is strained. Write down the utility number, a local contact, medical providers, and one person outside the immediate area. A paper list still works after a dead battery, a lost password, or an overloaded network.
Also check smoke and carbon monoxide alarms. If the power is out, people often reach for fuel-burning equipment or alternative heat. A battery-powered or battery-backup carbon monoxide alarm matters because carbon monoxide cannot be seen or smelled. Generators, charcoal grills, camp stoves, and gasoline-powered engines belong outdoors and far away from doors, windows, and vents. Never use a stove or oven to heat the home.

Add the things your household cannot simply do without.
The basic kit is only the baseline. If someone uses powered medical equipment, depends on refrigerated medicine, has mobility needs, or needs assistive technology, make a specific backup plan before an outage. Ask the care provider, pharmacist, equipment supplier, or local utility what applies to that need. Do not wait until the power is already off to discover whether a device battery holds four hours or two days.
Families with infants may need formula, bottles, diapers, wipes, and a way to clean them safely. Pet supplies belong in the plan too: food, water, medication, a leash or carrier, and a current photo. For cold weather, add layers, blankets, sleeping bags, and a clear decision about when the house is too cold to stay in. For heat, add extra water, cooling options, and a place to go before a vulnerable person becomes overheated.
Keep a basic first-aid kit and an extra supply of regularly used items when practical. The American Red Cross power-outage checklist calls out a seven-day supply of medications, but the right amount depends on your prescriptions, storage requirements, and clinician’s advice. What matters is having a real plan for the items you cannot replace quickly.
Write a short plan next to the supplies.
A kit works better when it includes a few decisions already made. Keep a one-page note with the address, utility contact, nearest safe place to go, emergency contacts, and the location of the electrical panel, water shutoff, and manual garage release. Add a note about who checks on whom. If the outage happens while people are in different places, this turns a string of worried calls into a simple check-in plan.
Choose the moments that change your response: an extreme heat or cold warning, a powered medical need, a damaged home, a local evacuation order, or an outage that looks likely to last through the night. You do not need to predict every scenario. You need to recognize when staying home is no longer the best option. The first-24-hours outage guide can help when that moment arrives.
Review the kit twice a year and ahead of the season when outages are most likely in your area. Check dates, test lights, charge power banks, update contacts, and replace what you used. A twenty-minute reset is much easier than a frantic shopping trip after a storm forecast appears.
Keep the kit simple enough to use.
It is easy to turn outage preparation into a shopping list with no end. Resist that. A useful kit should make the first few decisions easier, not require you to learn a new hobby. Avoid relying on one expensive gadget, one app, or one piece of equipment that only works under ideal conditions. Redundancy can be modest: a second flashlight, a paper contact list, a manual can opener, or a charged power bank is often more useful than a complicated system that nobody maintains.
Generators and large battery systems can be valuable for a household with a specific need, but they are separate safety projects, not a substitute for the basics. Know which equipment you need to keep running, how long it must run, where it can operate safely, and who can use it. Never run a generator indoors, in a garage, or near doors, windows, or vents. If backup power is part of your plan, read the manufacturer’s instructions and follow local electrical guidance before an outage, not during one.
Finally, leave room for ordinary comfort. A familiar game, books, a deck of cards, a pet’s blanket, or a favorite shelf-stable snack will not solve a safety problem, but they can make a long evening feel more manageable. Preparedness is not about making a house look dramatic. It is about keeping people steady enough to make good choices.

Frequently asked questions
Power outage kit questions.
What should be in a power outage emergency kit?
Start with water, shelf-stable food, safe lighting, batteries, a way to charge a phone, a radio, first-aid supplies, needed medicines, a manual can opener, a cooler and ice packs, and a written contact list. Then add what your household specifically needs for temperature, mobility, pets, infants, or medical equipment.
How much water should I keep for a power outage?
A common starting point is one gallon per person per day. Keep more when heat, a well pump, pets, sanitation needs, or a longer disruption could make water harder to get. Store it where you can reach it without moving a crowded pantry in the dark.
Should I buy a generator for a power outage?
A generator is not the starting point for every household. First cover water, light, food, communication, and medicine. If you do use a generator, follow its instructions exactly, keep it outdoors and far from openings, and make a plan for the equipment that truly needs power.
How often should I check a power outage kit?
Check it at least twice a year and before a season when outages are more likely where you live. Replace expired food, refresh water, test lights and power banks, update contacts, and make sure seasonal clothing still fits the people who may need it.
