Most Homes Are Not Ready for a Serious Outage
The average U.S. household experiences more than 8 hours of power outage per year — and in storm-prone regions, multi-day outages are an increasingly common reality. Most homeowners have a flashlight somewhere and maybe some candles, but a real outage preparation plan covers food safety, water, medical equipment, communication, heating and cooling, and backup power well before the lights go out.
This guide gives you a complete, actionable checklist — organized by priority — so you can prepare systematically rather than scrambling the night before a storm.
Tier 1: Essential Preparation (Every Home Needs This)
Backup Lighting
Have at least three independent lighting sources that do not depend on the grid:
- LED headlamps for each family member — hands-free lighting is far more practical than handheld flashlights during extended outages
- Battery-powered LED lanterns for common areas — provide ambient lighting without fire risk
- Rechargeable power banks charged before an outage to keep phones and small devices running
Avoid candles as a primary light source — they are a significant fire risk during extended outages when people are tired and distracted.
Water Supply
FEMA recommends storing at least one gallon of water per person per day for a minimum of three days. For a family of four, that means 12 gallons minimum — 30 gallons covers a week. If your home uses a well with an electric pump, your water supply is directly dependent on grid power. A portable power station or generator that can run your well pump becomes a water supply issue, not just a convenience.
- Store water in food-grade containers — commercially available water storage containers or clean 2-liter bottles
- Fill your bathtub using a WaterBOB bladder insert if a storm is approaching — provides 100 gallons of emergency drinking water storage
- Know where your water shutoff is located in case of pipe damage
Food Safety and Non-Perishable Supplies
- Keep a 72-hour supply of non-perishable food that requires no cooking — canned goods, nuts, dried fruit, crackers, peanut butter
- A refrigerator maintains safe food temperature for approximately 4 hours when closed. A full freezer stays safe for 48 hours, a half-full freezer for 24 hours
- Keep a manual can opener in your emergency kit — electric can openers are useless during an outage
- Fill a cooler with ice when an outage is anticipated for refrigerator overflow items
Communication and Information
- A battery-powered or hand-crank NOAA weather radio — receives emergency broadcasts when cell networks are overwhelmed
- Keep all phones charged before anticipated storms. A 20,000 mAh power bank fully charged can recharge most smartphones 4 to 6 times
- Know your local emergency notification system — sign up for county alerts via text
- Keep a written list of emergency contact numbers — do not rely solely on your phone’s contact list
Tier 2: Comfort and Extended Outage Preparation
Backup Power
The right backup power solution depends on your outage history, home size, and budget. Three practical options for most homeowners:
- Portable power station (1,000 to 2,000 Wh): Covers essential electronics, refrigerator cycling, phone charging, and CPAP without noise, fuel, or outdoor placement. Best for most suburban homeowners with typical 12 to 24 hour outages. See our guide to the best portable power stations for home backup.
- Portable gas generator (5,000 to 7,500W): Higher output for running AC, well pumps, and multiple appliances simultaneously. Requires outdoor placement 20+ feet from the home and a fuel supply. Best for areas with frequent multi-day outages.
- Whole-home standby generator: Automatic, runs on natural gas or propane, covers all circuits. Best-in-class convenience at significant installation cost.
Whatever backup power you choose, buy it before storm season — availability disappears and prices spike when a major storm is approaching.

Heating and Cooling
Temperature extremes during extended outages cause more serious medical emergencies than almost any other outage factor. Plan specifically for your climate:
- Cold weather: Identify a warm room in your home and plan to heat only that space. A properly sized propane or kerosene heater with adequate ventilation can maintain one room safely. Sleeping bags rated to 0°F are excellent insurance.
- Hot weather: A window AC unit drawing 1,000 to 1,200W is manageable with a mid-size portable power station. Keep blinds closed during the day to reduce heat load. Battery-powered fans buy significant cooling time at much lower power draw.
- Know the location of your nearest emergency cooling center or warming shelter — communities open these during extended extreme weather events.
Medical Equipment
If anyone in your household uses medical equipment that requires electricity — CPAP, home oxygen concentrator, nebulizer, refrigerated medication, powered wheelchair — outage preparation is a medical necessity, not a comfort issue. Steps to take before any outage:
- Register with your utility as a life-safety customer — most utilities maintain priority restoration lists for medical need households
- Ensure your backup power solution can run your equipment for at least 24 hours
- Keep medications that require refrigeration in a backup cooler plan — most insulin can be stored at room temperature for 28 days once opened
- Identify the nearest hospital or medical facility if power-dependent equipment cannot be backed up adequately
Tier 3: Whole-Home Protection Before Outages Occur
Whole Home Surge Protector
When power returns after an outage it often returns with a voltage spike. Appliances across the house can be damaged in the restoration event itself. A whole home surge protector installed at your electrical panel is the single most effective protection against this. See our guide to whole home surge protectors for specific product recommendations.
Generator Transfer Switch or Interlock
If you plan to connect a generator to your home\’s electrical system, a proper transfer switch or interlock kit is a legal requirement in most jurisdictions and a safety necessity. Never plug a generator into a wall outlet — this creates a potentially fatal backfeed hazard for utility workers.
The Complete Power Outage Preparation Checklist
- LED headlamps for each family member
- Battery-powered LED lanterns (2 minimum)
- Charged power banks for phones
- NOAA weather radio
- 72-hour minimum water storage (1 gallon/person/day)
- 72-hour non-perishable food supply
- Manual can opener
- First aid kit checked and restocked
- Backup power solution (power station or generator) purchased and tested
- Fuel or battery stored and maintained for backup power
- Whole home surge protector installed
- Generator transfer switch or interlock installed (if using generator)
- Medical equipment backup power verified
- Utility life-safety registration completed (if applicable)
- Emergency contacts list printed and stored physically
- County emergency alert notifications enabled on your phone
Bottom Line
Outage preparation is not about paranoia — it is about making a series of small decisions and purchases in advance so that when the power goes out, your household continues functioning safely and comfortably rather than scrambling. Work through the tiers above and address the most critical items first. Most of the essential preparation can be completed for under $200 and takes a single afternoon.
