A power outage that lasts a few hours is an inconvenience. One that lasts days — after a hurricane, ice storm, or grid failure — is a different situation that calls for a plan. The households that come through an extended outage comfortably are not the ones with the most gear; they are the ones who act calmly in the right order. Here is a practical, step‑by‑step guide to what to do when the power stays off.

First hour: assess and stabilize

When the power goes out, first find out how big the problem is. Check whether your neighbors have power — if they do, the issue may be your own breaker. If the whole area is dark, report the outage to your utility and check their map for an estimated restoration time. Then stabilize: gather everyone, get out your lights, and silence any panic. A good lantern or headlamp in each room turns a stressful dark house into a manageable one. Note the time so you can track how long food has been without cooling.

Protect your food and water

Immediately shift into food‑protection mode: keep the refrigerator and freezer closed (a closed fridge holds safe temperatures for about four hours, a full freezer for up to two days), and move only what you need. Our guide on keeping your refrigerator running during an outage covers the details. If the outage follows a disaster that may have affected water service, fill containers and the bathtub while pressure holds, and treat tap water as suspect until officials say otherwise — see our water storage and purification guide.

Manage heat and cold

Temperature is the hidden danger of a long outage. In winter, close off unused rooms, hang blankets over windows, and gather the household into one room to share body heat; dress in layers and use cold-rated sleeping bags. Never heat a home with a gas stove, oven, or charcoal grill — they produce deadly carbon monoxide. In summer, do the opposite: shade windows during the day, open up at night, hydrate constantly, and move to the lowest, coolest level of your home. For a winter‑specific plan, see our winter power outage survival guide.

Stay informed without your phone

In an extended outage your phone is both a lifeline and a liability — you need its information but must protect its battery. Switch it to low‑power mode, dim the screen, and stop using it for entertainment. Get your emergency information instead from a battery or hand‑crank NOAA weather radio, which broadcasts official updates without draining your phone. Keep a couple of charged power banks in reserve for phones, and ration their use for genuine communication, not scrolling.

Power the essentials

Decide deliberately what truly needs electricity: medical devices like a CPAP or anything refrigerated such as insulin, then phones and lights. A battery power station runs these quietly and safely indoors; a generator runs larger loads but must always be operated outdoors, far from windows, because of carbon monoxide. For how to choose and size backup power, see our backup power comparison, plus the reviews at HomePowerVault and GeneratorAdvice. Run backup power for the essentials, not the whole house.

Safety through the days

Long outages bring their own hazards. Put a working battery carbon-monoxide detector on every level if you are using any fuel‑burning device. Unplug sensitive electronics to protect them from the surge when power returns, but leave one light switched on so you know the moment it does. Check on elderly neighbors and anyone who depends on powered medical equipment. And keep some cash on hand — ATMs and card readers fail when the power and networks are down.

When it stretches on

If an outage lasts beyond a couple of days, shift from riding it out to sustaining your household: cook from your pantry using off‑grid methods, conserve water, and maintain a simple daily routine for meals, light, and rest. If your home becomes unsafe — too cold, too hot, or out of essential supplies — know where to go, whether a relative’s home or a community warming or cooling center. Preparedness is what turns a multi‑day outage from an emergency into an inconvenience; our emergency preparedness guide covers building that foundation before you ever need it.

When the power comes back

Restoration has its own short checklist. Power often returns in surges, so turn major appliances and electronics back on gradually over several minutes rather than all at once, which protects them and eases the load on a recovering grid. Check your refrigerator and freezer temperatures before trusting the food inside, and throw out anything that climbed above 40°F for more than two hours. Refill and refreeze your water jugs and ice packs, recharge every power bank and power station, and restock anything you used so you are ready for the next event. Take a few minutes to note what worked and what you wished you had — the gap you felt at hour forty of this outage is the most honest shopping list you will ever get for the next one.

Key takeaways

• Assess first: check whether it is just your home, report the outage, and note the time.
• Keep the fridge and freezer closed and protect your water supply early.
• Manage temperature safely — never use a stove, oven, or grill to heat a home.
• Protect phone batteries; get official updates from a weather radio.
• Run backup power for essentials only, and keep a CO detector wherever fuel is burned.

Frequently asked questions

How long can a power outage safely last at home? With preparation, most households can stay safe for days; the limiting factors are temperature, water, medication, and food safety rather than a fixed number.

What should I do first when the power goes out? Check whether neighbors are affected, report the outage, get out your lights, and note the time so you can track food safety.

How do I keep my phone working in a long outage? Use low-power mode, get news from a weather radio instead, and recharge from power banks, your car, or a power station.
