How to Prepare Your Home for a Power Outage

Most households don't think about power outages until they're sitting in the dark. By then, the flashlight batteries are dead, the phone is at 12%, and nobody knows where the candles are. A little preparation changes everything.

The good news: you don't need a bunker or a $10,000 generator. You need a realistic plan for the first 72 hours - the window most outages fall within, and the window where your household is on its own before utility crews restore service.

Start with the essentials: power, light, communication

Your phone is your lifeline during an outage. It's your flashlight, your weather radio, your contact with family, and your connection to utility updates. A dead phone means you're blind. Priority one is keeping it charged.

A portable power station with LFP (lithium iron phosphate) chemistry is the safest option for indoor use. Unlike gas generators, there's no carbon monoxide risk. Unlike lead-acid batteries, LFP is stable, lightweight, and lasts thousands of cycles. A 1-1.5 kWh unit can keep phones, a Wi-Fi router, LED lights, and a weather radio running for up to three days depending on usage.

LED lanterns or a lighting kit eliminates the candle risk (house fires spike during outages) and makes your home livable after dark. A NOAA weather radio gives you real-time storm updates even when cell towers are overloaded.

Food and water: the 72-hour window

Your fridge keeps food safe for about 4 hours without power if the doors stay closed. A full freezer holds temperature for roughly 48 hours. After that, you're making judgment calls about what's safe to eat.

A battery backup that can cycle a fridge on and off - running the compressor for 15 minutes every hour - can stretch food safety well beyond 72 hours. This isn't about running the fridge normally; it's about keeping the internal temperature below 40°F.

For water, most municipal systems maintain pressure during outages, but boil-water advisories are common after storms. A compact water filter handles both scenarios. Fill containers while you still have pressure, and filter if the advisory comes.

Medical devices and essential equipment

If anyone in your household uses a CPAP, nebulizer, or other powered medical device, backup power is a priority. Most modern CPAP machines draw 30-60W depending on humidifier and heated tube settings. A 1 kWh battery can run a typical CPAP for roughly 15-30 hours depending on those settings. Check your specific model's wattage.

Make a list of every device in your home that someone depends on. Check the wattage. Do the math. Your backup battery needs to cover the essentials for 72 hours, not everything in the house.

The checklist

Don't wait for the warning

The worst time to prepare is when a storm is already in the forecast. Stores sell out, shipping slows down, and you're making compromises instead of choices. The Ladegrid Family 72 kit includes everything on this checklist except the food and water - 1.5 kWh battery, lights, radio, water filter, first aid, cables, and a printed outage plan, all in one case. Store it in a closet and forget about it until you need it.
