Storm-Season Power-Prep Checklist: How to Stay Powered Through an Outage (2026)
A storm-season power-prep checklist comes down to four things: know what you must keep running, size backup power to match those loads, protect food and medications, and operate any generator safely outdoors. Do those four well before a storm is in the forecast and a multi-day outage becomes an inconvenience instead of an emergency. You do not need the biggest battery or generator on the shelf — you need the right one for your home.
Why prep even in a quiet forecast year
NOAA’s 2026 Atlantic outlook calls for a below-normal season, with roughly 8 to 14 named storms and one to three major hurricanes expected. But a seasonal outlook is not a landfall forecast, and it only takes one storm — or one downed line in a summer thunderstorm — to knock out power for days. Preparation is about the outage you actually experience, not the regional average.
Step 1: List what you actually need to run
Before buying anything, write down the loads that matter during an outage. Most households fall into three tiers:
Critical: medical devices (CPAP, oxygen concentrator, medication refrigeration), phones, a few lights, and your internet router.
Comfort: refrigerator, a fan or small AC unit, laptop, and kitchen counter appliances.
Whole-home: well pump, central HVAC, electric range. These draw far more and usually call for a larger system or a vetted installer.
Add up the watts for the tier you want to cover. This single list is what right-sizes everything that follows. Our How It Works page (thefortify.co/how-it-works) walks through the same load math step by step.
Step 2: Match backup power to the loads
There is no single best backup product. There is the one that fits your list, your space, and your budget.
Portable power stations
Lithium battery units that recharge from a wall outlet or solar. They are quiet, produce no exhaust, and are safe to run indoors, which makes them ideal for renters and for keeping phones, medical devices, a router, and small appliances going. Match the unit’s watt-hours to how long you need to run your critical tier.
Home backup batteries
Larger fixed or semi-fixed batteries that cover more of the house for longer, often paired with solar. A good fit when you want the refrigerator and several circuits to ride through a multi-day outage without refueling.
Portable generators
High output and good for whole-home or heavy loads, but they burn fuel and produce carbon monoxide, so placement matters (see Step 4). Many households pair a generator for big loads with a battery for quiet, indoor-safe overnight power.
Browse vendor-neutral options sized to each tier in the Fortify Shop (shop.thefortify.co).
Step 3: Protect food, medication, and devices
Refrigerator and freezer: keep the doors closed. A closed fridge holds safe temperatures about 4 hours, and a full freezer holds roughly 48 hours, per Ready.gov. Discard food held above 40 degrees F for two hours or more.
Medication: ask your provider now how long refrigerated medicines can sit warm, and have a plan to keep them cold. If the power is out more than a day, follow your pharmacist’s guidance on refrigerated drugs.
Devices and data: keep phones and battery banks topped off before the storm, and know which outlets on your power station are reserved for critical gear.
Kit basics: nonperishable food, water, a manual can opener, flashlights, and a battery or hand-crank radio. See the standard Ready.gov build-a-kit list (ready.gov/kit).
Step 4: Run backup power safely
Carbon monoxide from portable generators kills about 100 people in the U.S. each year, according to the Consumer Product Safety Commission. The rules are simple and non-negotiable:
Never run a generator indoors, in a garage, basement, crawlspace, or on a porch or carport. Opening windows does not provide enough ventilation.
Run it outside only, at least 20 feet from the house, with exhaust pointed away from doors, windows, and vents.
Choose models certified to the latest UL 2201 / PGMA G300 standards with an automatic CO shut-off feature.
Install battery-powered carbon monoxide alarms on every level of the home and outside sleeping areas.
Battery power stations and home batteries produce no exhaust, which is why they are the safe choice for indoor and overnight use.
The 10-minute pre-storm checklist
When a storm enters the forecast, run through this:
Charge every battery, power station, and phone to full.
Fill the freezer (it holds cold longer when full) and group critical items together.
Set the fridge and freezer to their coldest settings.
Confirm the fuel supply and placement plan for any generator.
Test carbon monoxide and smoke alarms.
Stage flashlights, water, and your medication-cooling plan where you can reach them in the dark.
Frequently asked questions
How big a power station do I need to keep my essentials running?
Add up the wattage of your critical loads (lights, phone, router, a medical device) and multiply by the hours you want to cover. That watt-hour figure is your target battery capacity. A modest unit often covers a critical tier for a day; the load walkthrough on our How It Works page (thefortify.co/how-it-works) shows how.
Can I run a portable power station indoors?
Yes. Lithium power stations and home batteries produce no exhaust or carbon monoxide, so they are safe to use indoors and overnight, unlike fuel-burning generators, which must always run outdoors and well away from the house.
How long will food stay safe in my fridge during an outage?
About 4 hours in a closed refrigerator and roughly 48 hours in a full, closed freezer, per Ready.gov. Keep the doors shut, and discard anything held above 40 degrees F for two hours or more.
Do I need a whole-home system to be prepared?
No. Most households start by backing up only critical and comfort loads, which a power station or home battery handles well. Whole-home coverage of HVAC, well pumps, or electric ranges is a larger project best scoped with a vetted installer.
