Power Outage Kit: Complete Emergency Supply List
Build a practical power outage kit with emergency lighting, water, food, backup power, communication, medical supplies, sanitation essentials and home-safety equipment matched to your household.
A Useful Blackout Kit Must Be
What Is a Power Outage Kit?
A power outage kit is the organized collection of supplies you will actually use when electricity, internet service, refrigeration, heating, cooling or well pumps stop working.
The power outage preparedness checklist covers the actions your household should complete before, during and after a blackout. This power outage kit guide focuses on the physical supplies needed to carry out that plan.
A good blackout kit should not be one giant plastic tote buried behind holiday decorations. Put frequently needed items—especially flashlights, headlamps and phone power—where they can be reached immediately. Keep the deeper food, water, sanitation and backup-power supplies in a central, clearly labeled location.
Start With the Problems a Blackout Creates
Electricity loss can affect far more than lights. Depending on your home, it may also disable refrigeration, cooking appliances, heating systems, air conditioning, internet equipment, garage doors, medical devices, security equipment and electric well pumps. Build the kit around the specific systems your family depends on.
Power Outage Kit Supply Calculator
Estimate a basic starting quantity for stored water and meals. Then customize the kit for pets, medical needs, hot weather, well water and longer outages.
Your Household Starting Point
The calculator uses a one-gallon-per-person-per-day water baseline and three meal portions per person per day. It is a planning aid, not a substitute for official instructions or individualized medical guidance.
Build the Kit in Four Levels
Prioritize the supplies that solve immediate safety problems, then expand the kit for longer outages.
Emergency Lighting for a Power Outage Kit
Use several types of lighting so one dead battery or failed device does not leave the entire household in darkness.
Personal Flashlights
Keep a dependable flashlight for each responsible household member. Store one beside each bed and near primary exits.
Headlamps
Hands-free lighting is useful for first aid, cooking, utility checks, carrying children and moving supplies.
Room Lanterns
Use stable LED lanterns for shared rooms, bathrooms and kitchen work areas. Choose models with adjustable brightness to conserve power.
Battery Plan
Standardize battery sizes when practical, label rechargeable cells and keep backup batteries protected from heat and moisture.
Place lights before an outage occurs. Do not rely on finding a single flashlight in a dark garage. The future guide to the best emergency lights for power outages will compare lanterns, headlamps and rechargeable options.
Communication and Information Supplies
Build several ways to receive alerts and contact others when home internet or cellular networks are congested.
Write key information on paper. A phone with a dead battery cannot provide contacts, medication lists or account numbers. See the future emergency radio guide for weather-alert and charging features.
Backup Power Supplies
Choose backup power only after listing the devices that must run, their starting wattage, running wattage and required runtime.
Small Power Banks
Best for phones, USB lights, small radios and low-power electronics. Recharge them on a schedule.
Portable Power Stations
Useful for selected appliances and electronics when capacity, output and surge ratings match the actual load.
Solar Recharging
Can extend runtime when sunlight, panel placement and charging conditions are adequate. Test the complete system in advance.
Fuel-Powered Generators
Can support larger loads, but require safe outdoor placement, fuel planning, maintenance and carbon-monoxide protection.
Keep heavy-duty outdoor-rated extension cords that match the generator load and inspect them before use. Never connect a portable generator directly to household wiring without properly installed transfer equipment and qualified electrical work.
Use the future solar generator sizing guide before buying, then compare options in the future best solar generators for power outages guide.
Food, Water and Cooking Supplies
Build the food and water section around items that require little refrigeration, limited fuel and minimal cleanup.
| Category | What to Store | Why It Matters |
|---|---|---|
| Drinking water | Food-grade bottled or stored water, smaller portable bottles and pet water | Municipal service, well pumps or treatment systems may fail during an outage. |
| No-cook food | Nut butter, crackers, canned meat, beans, fruit, bars and shelf-stable meals | Reduces dependence on electricity and cooking fuel. |
| Opening and serving | Manual can opener, utensils, paper plates, cups and paper towels | Prevents a kit full of food that cannot be opened or served. |
| Cold storage | Appliance thermometers, coolers, frozen gel packs and an ice plan | Helps monitor and preserve food safely during longer outages. |
| Backup cooking | Only approved equipment, correct fuel and required outdoor setup | Improvised indoor combustion can cause fires or carbon-monoxide poisoning. |
Refrigerator and Freezer Tools
Keep appliance thermometers in both units. An unopened refrigerator generally keeps food cold for about four hours. A full freezer can hold its temperature for about 48 hours, while a half-full freezer may hold it for about 24 hours when the door stays closed. The future food safety without power guide will provide the complete timeline and discard chart.
Cooking Equipment
Prioritize no-cook meals first. For longer outages, use only equipment approved for the intended location and follow its directions. The future emergency cooking without electricity guide will cover safe meal options and outdoor cooking setups.
Health, Medical and Sanitation Supplies
A generic blackout kit is incomplete until it covers medication, medical equipment, hygiene and toilet needs.
First Aid
Keep a stocked first aid kit, gloves, wound-care supplies, thermometer and any training-specific equipment you know how to use.
Medication
Maintain an updated medication list, pharmacy contacts and an emergency refill plan developed with healthcare providers.
Medical Devices
Record battery runtime, charging requirements, backup locations and transportation plans for essential powered devices.
Sanitation
Store soap, sanitizer, toilet paper, heavy-duty bags, disinfecting supplies, disposable gloves and a plan for water outages.
Medical continuity should be planned with qualified providers and equipment suppliers. The future medical device power outage guide will include a runtime worksheet. Homes with electric well pumps should also use the future well-water outage guide.
Heating and Cooling Supplies
Blackouts can become medical emergencies when a home becomes dangerously hot or cold.
Do not use outdoor grills, charcoal devices or unapproved heaters indoors. Read the future guide on how to stay warm without electricity for safer cold-weather planning.
Tools, Home Safety and Important Documents
Small support items often determine whether the main equipment can actually be used.
Basic Tools
Work gloves, adjustable wrench, screwdrivers, pliers, utility knife, duct tape, cable ties and spare hardware appropriate for your equipment.
Fire and CO Safety
Working smoke alarms, battery-backup carbon monoxide detectors and suitable fire extinguishers.
Documents
Printed contacts, identification copies, insurance information, medication lists, device instructions and utility account details.
Cash and Access
Small-denomination cash, spare keys, a manual garage-door plan and a safe method to enter or leave the property.

Build a Power Outage Kit on a Budget
Do not delay basic readiness because the ideal kit feels expensive. Build the essential layers first and upgrade over time.
Use What You Own
Gather existing flashlights, blankets, coolers, tools, chargers and shelf-stable food. Test everything and move it into a defined kit.
Add One Category at a Time
Start with lighting and phone power, then water, food, medical supplies, sanitation and finally larger backup-power equipment.

Power Outage Kit FAQ
Answers to common questions about building and maintaining a home blackout kit.
What should be in a power outage kit?
A complete kit should include emergency lighting, batteries, a radio, phone power banks, stored water, shelf-stable food, a manual can opener, first aid supplies, medication, hygiene items, seasonal temperature protection, important documents and supplies for pets or special needs.
How much water should I put in a blackout kit?
A common emergency-planning baseline is one gallon per person per day. Add more for pets, hot weather, illness, food preparation, sanitation and homes that depend on an electric well pump.
How many days should a power outage kit cover?
Begin with at least three days of core supplies and expand based on local outage history, climate, household medical needs, water access, storage space and budget.
Where should a power outage kit be stored?
Keep the main kit in a cool, dry, accessible location. Distribute immediate-use lights near beds, stairs and exits so household members do not need to search for the central kit in darkness.
Should candles be included in a blackout kit?
LED flashlights and lanterns are generally safer because they do not introduce an open flame. When candles are used, they require strict fire-safety precautions and continuous supervision.
Can a portable power station run a refrigerator?
Some models can, but only when their continuous output and surge capacity match the refrigerator and the battery capacity provides acceptable runtime. Test the exact combination before relying on it.
How often should the kit be inspected?
Inspect the kit at least every six months and before major storm seasons. Recharge batteries, rotate food and water, update medications and contacts, test equipment and replace damaged supplies.
What is the difference between a power outage kit and a general emergency kit?
A general emergency kit covers many hazards. A power outage kit adds blackout-specific supplies such as layered lighting, device charging, refrigerator thermometers, backup power, generator safety equipment and heating or cooling plans.
