Power Outage
Take a breath. Most outages are back within a few hours. Here's how to keep your food safe, your phone alive, and everyone comfortable while you wait.
The moment the power drops, your fridge begins warming up. Kept shut, it holds food safely for about four hours, and a full freezer can last up to two days. The catch is that every time you open the door to check, you let the cold out and shorten that window. Treat it like a cooler you are rationing — not a cabinet you keep opening.
With nothing to plug into, your battery quietly becomes your most important supply. It is your flashlight, your weather updates, and your way to reach family, all at once. Most people burn through it fast out of nervous habit — checking, refreshing, scrolling. Protecting that charge in the first hour matters far more than it feels like it should.
Anything that plugs in to keep someone well — a CPAP, an oxygen concentrator, a fridge full of insulin — goes quiet the instant the grid does. For a lot of families, this is the part that turns an inconvenience into something serious. If someone at home depends on a device, it needs a backup plan before the next outage, not during one. There's a whole section on this below.
Your furnace and air conditioner both run on power, so they stop right away. After that, your home slowly drifts toward whatever it is outside — cooling down in winter, heating up in summer. A well-sealed house buys you hours, but not forever. In a hard freeze or a heat wave, the indoor temperature becomes the thing to watch most closely.
You can do every one of these right now, with what's already in your home.

If someone uses a CPAP or home oxygen. These machines need steady power, and a night without apnea support or oxygen is not something to gamble on. A battery power station sized to the device is the real fix — set it up and test it before you ever need it. Many CPAP users can get through one night by sleeping propped up, but check with your doctor first, and if someone is on home oxygen, call your supplier now about backup tanks.
If someone depends on insulin. Insulin lives in the fridge, but it doesn't go bad the instant the power dies. Most types stay usable at room temperature for a stretch — often around 28 days — so don't panic, and don't pack it against ice, which can freeze and ruin it. Keep it in the warm part of a cooler, and call your pharmacy or the manufacturer's line if you're unsure about your specific insulin.
If you have a baby or young kids. Formula-fed babies need clean water for bottles, so boil and cool tap water if there is any advisory, and warm bottles in a bowl of hot water rather than guessing. Little kids lose and gain heat faster than adults — layer them up in the cold, keep them shaded and sipping water in the heat. A familiar toy and a flashlight go a long way; calm parents make calm kids.
If an older adult lives with you. Older bodies handle temperature swings poorly and can get into trouble before they think to mention it. Check on them often, dress them for the room's real temperature, and make sure they keep drinking water. If they take medications that affect heat or hydration, an outage is a good reason to move them somewhere climate-controlled sooner rather than later.
Even with the door open, carbon monoxide builds in minutes. Outside only, at least 20 feet from windows and doors — per the CDC.
Every open costs you cold. Kept shut, a fridge holds safe temps for about 4 hours and a full freezer 24–48 hours — per USDA.
Ovens aren't vented for that, and the CO risk is real — per the CDC. Layers, one warm room, and closed doors work better than you'd think.
Put one phone on low-power mode and make it the household's lifeline. Texts get through when calls won't, and they sip battery.
If outages are common where you live, a battery power station keeps your fridge, phones, and a light running — quietly, indoors, with no fumes.

About four hours in the fridge if you keep the door shut, and up to 48 hours in a full freezer. The rule that matters is temperature, not time — anything that has sat above 40°F for more than two hours should go. A cheap fridge thermometer takes the guesswork out before you eat something questionable.
If it's a gas stove you light with a match or igniter, it works fine for cooking. What's not safe is using that stove or oven to heat your home — it can build up carbon monoxide indoors. Cook with a window cracked, and never leave a burner running for warmth.
No — not even with the door open. A portable generator gives off carbon monoxide that can kill within minutes, and a garage traps it fast. Run it outside, at least 20 feet from the house, pointed away from windows and doors. Indoors, a battery power station is the safe alternative.
For a single night, many people can sleep without it by propping themselves upright — but confirm that with their doctor ahead of time. The dependable fix is a battery power station rated for the machine's wattage, charged and tested before an outage. If they also use oxygen, call the supplier now about backup tanks.
Close blinds and curtains on the sunny side, and keep windows shut through the hottest hours so you are not letting heat in. Open them at night when the air is cooler to flush the warmth out. Move to the lowest floor, drink water steadily, and put a damp cloth on your neck and wrists.
Only for a real emergency — a medical crisis, a fire, or someone in danger. Don't call 911 to report the outage or ask when power's coming back; that ties up lines other people need. Use your utility's outage number or app for updates, and a battery weather radio if your phone is dead.
A standard sump pump runs on house power, so it stops the moment the grid does — and in a storm, water can rise in the pit within hours. A battery backup pump or a power station keeps it running. Short of that, a manual pump or a shop vac can buy you time.
Same rules apply, but a garage fridge struggles more because the air around it swings hot and cold. In summer it warms faster than one inside the house. Keep it shut, check the temperature, and move anything truly perishable into a cooler with ice if the outage runs past a few hours.
The calmest households aren't the most worried ones — they just have a plan. Once this passes, a few quiet minutes now saves a lot of stress next time.
