What to Do When the Power Goes Out: A No-Panic Preparedness Guide

The Deadline That Didn't Slip

I'm three layout revisions into a client's rebrand when I notice the WiFi icon on my laptop still shows full bars, even though the storm alert on my phone says the worst of it passed an hour ago. Somewhere behind the garage, our backup system did exactly what it's supposed to do: it kept running without anyone in the house noticing it had switched on. That's what real family safety looks like during Houston power outages: nobody scrambling, nobody hunting for a flashlight app while the hallway goes black. After two outages in the same year, we stopped treating backup power like an afterthought and started treating emergency preparedness like a system you test, not a drawer you forget about.

We get some version of the same questions from neighbors, from the parents on my husband's little league team, and lately from strangers who found this site after their own rough week. So instead of another origin story, here's what we actually tell people, roughly in the order the questions come.

Is It Just Us, or the Whole Block?

She says: My part of the assessment is digital. I open the utility's outage map and the neighborhood app within the first minute, because knowing whether it's one tripped line or a grid-wide failure changes everything that happens next. If it's just our stretch of the cul-de-sac in Pearland, a repair truck might already be rolling. If the whole south side of the region has gone quiet at once, we're settling in for hours.

He says: My part is physical. I go straight to the breaker box and check for a tripped main before assuming the whole neighborhood is out. If it really is the grid, the main breaker gets shut off before anything else happens, full stop: this prevents a home generator from backfeeding power into lines a utility crew thinks are dead. It takes ten seconds, and it's the one step people skip when they're rattled.

The rule we go by is simple: don't touch a generator or a power station until you actually know which kind of outage you're dealing with.

Deciding What Gets Plugged In First

A reader named Dwight, who lives a few streets over and found us after the last big outage, asked us something blunt: how do you decide what gets power first when everything feels urgent? For his family, it's a home oxygen concentrator for his son. For ours, it's insulin that can't sit above 46 degrees in the kitchen fridge. Neither of those loads negotiates, so they get power before the WiFi, before the TV, before anything merely convenient.

He asked exactly the right follow-up questions, too, then went quiet for a few weeks before circling back to say the math finally clicked. We've written elsewhere about sizing a generator specifically around a medical device like his concentrator, because that deserves its own page rather than a paragraph tucked into a general guide.

This part of our list didn't exist from day one. Before we'd built any real priority order, an outage caught us mid-afternoon with no plan beyond hoping the fridge held its temperature long enough on its own. It didn't. By the time we'd found a cooler and enough ice, the insulin had sat above its safe range for longer than either of us was comfortable admitting. Nothing happened to our son that day, but it scared us into building an actual list instead of improvising one every time the lights dropped.

If you only rank one thing correctly, rank the medical equipment first. Everything else can wait an hour. That can't.

How Much Backup Power Do You Actually Have?

Think of a battery or a generator as a checking account with a fixed balance in watt-hours, and every appliance you plug in writes a check against it. Our design setup — laptop, two monitors, a router — draws around 160 watts while it's running. A motor-driven appliance like a refrigerator is trickier, because it needs a much bigger burst just to start turning than it does once it's already spinning, which is the difference between running watts and starting watts. That gap is exactly why a battery rated for 1,800 watts can still stall out on a fridge that only draws 700 watts to run but spikes well past that the instant it starts.

You'll find these numbers on the appliance label itself, usually listed in watts or in amps, and if you only see amps, multiplying by 120 gets you the watt figure everything else in this math depends on. We've broken that math down appliance by appliance in our wattage worksheet built for hurricane season, so we won't repeat all of it here.

Our neighbor Cheryl, two doors down, didn't believe any of these numbers until she watched us test them. She wants the math shown, not just claimed, so during one of our quarterly dry runs she stood behind the garage on the slab we use for gear testing, timing how long a fully charged power station actually kept the router and both monitors alive against what the spec sheet promised. She still shows up with a calculator when she asks us about her own setup, and honestly, we respect it.

We've made the budgeting mistake ourselves. During an early outage, before we understood cord limits, we ran a space heater, a lamp, and a phone charger off the same extension cord because it was the only one long enough to reach the living room. The cord got hot enough to smell like melting plastic before we caught it and unplugged everything. Extension cords carry their own wattage limit printed right on the packaging, and we'd never once bothered to check it.

Know two numbers before a storm ever shows up: what your must-haves draw to run, and what your cord and your battery can actually carry. Guessing is how cords melt and batteries disappoint.

Generator or Battery Comes First

People assume the answer is always a generator, and for raw power it often is, but that's not where we'd point a new family to start. A portable power station runs silently and can sit close to the fridge or a medical device, while a gas generator has to stay outside no matter what. We lean on the battery first for anything that can't tolerate noise or exhaust, and bring in gas power only once the battery's watt-hours run out.

There's a longer comparison elsewhere on which of the two actually fits a given household budget, because that question alone fills its own page. Even once you've picked battery over gas, there's a separate trade-off buried inside that choice, between how quietly a source runs and how much raw output it can deliver, and we'd rather point you toward that breakdown than compress it into a sentence here.

Our first attempt at 'quiet' backup was a cheap inverter generator bought off a listing that promised library-level noise. It didn't deliver. Running it anywhere close to the house sounded like a leaf blower parked on the patio, loud enough that we gave up and pushed it back to where the fumes needed to go anyway. At that distance the noise mattered less, but the entire point of a quiet, night-friendly setup was gone.

That's part of why we eventually moved beyond gas cans as our main plan and let a battery carry the quiet, indoor-adjacent loads instead. Gas still earns its place for raw runtime, but it's high-maintenance: fuel needs rotating every few months or it goes stale, refueling in August humidity leaves a gas smell on your hands that doesn't rinse off in one wash, and during a real power outage the pumps at our nearest gas station usually need electricity too, so getting more fuel isn't guaranteed.

When quiet matters, whether for sleeping kids, close neighbors, or a medical device that needs to stay indoors, battery goes first and gas stays backup, not the other way around.

Twenty Feet Is Not a Suggestion

Gas generators produce carbon monoxide, and the rule around that isn't flexible: at least twenty feet from any window, door, or vent, every single time, regardless of the weather. Running one in a garage, even with the door propped wide open, can build a fatal concentration of CO within minutes, because the gas doesn't need much enclosed space to turn dangerous. Roughly one hundred people in the United States die every year from generator-related carbon monoxide poisoning, and most of those deaths trace back to a generator sitting closer to the house than it should have been.

We learned to respect that number the hard way. During one storm, trying to keep the extension cord short, we ran our generator just inside the garage with the door cracked for ventilation, convinced that counted as outside enough. Our CO detector disagreed, loudly, in the middle of the night, and we spent the rest of that night moving the generator, airing out the garage, and feeling genuinely lucky the alarm had actually worked. We measure the twenty feet with a tape measure now instead of eyeballing it.

Twenty feet isn't a distance you round down because you're tired or the cord's too short. It's the line between annoying and fatal, and we don't treat it as negotiable anymore.

What Hasn't Worked For Us

Four years into doing this, the failure we still wince about wasn't a generator or a wiring mistake. It was a portable power station we'd fully charged after our last dry run, then let sit untouched for months. When the next storm actually arrived, the unit powered on, showed a full battery icon briefly, and then died completely, drained by some background parasitic pull neither of us had thought to check beforehand. We pay closer attention now to the weather sensor mounted along our back fence line, watching pressure trends days out, just so we have enough lead time to retest everything before landfall instead of after.

We also steer clear of homemade battery banks or any wiring hack pulled from a forum thread, not because we're squeamish, but because a mistake in that territory tends to be electrical or chemical, not just inconvenient. Stick to plug-and-play systems rated for indoor use, and leave anything touching your home's actual wiring to a licensed electrician. There's a lot beyond the obvious basics that two blackouts taught us about real power, and most of it comes down to restraint, not gear.

Charged once isn't the same as ready. If you don't recheck a stored power station on some kind of schedule, assume it's dead until you've proven otherwise.

Whole-Home System or Just the Basics?

Not every family needs a system sized to run the entire house. Ours doesn't, and most of the families we hear from don't either — the goal is covering your actual critical loads, not chasing total independence from the grid for its own sake. There's a much wider spectrum between 'battery for the router' and 'whole-home standby generator wired into the panel' than most people assume, and we've mapped where different budgets and needs land on that spectrum in a separate piece, because answering it properly here would take over the whole guide.

Start with your critical loads, not with the biggest generator you can afford. Most families end up somewhere in the middle of that spectrum, not at either end.

Installing Without Calling an Electrician

People ask fairly often whether they can set any of this up themselves, and the honest answer depends entirely on what 'this' means. Plugging a power station into a wall outlet and running extension cords to a fridge and a router takes no special skill. Wiring a transfer switch into your home's panel is a different category of job entirely, and it's the line where we stop and call someone licensed, every time. We keep the transfer switch hardware, labeled and ready, in a bin on the garage shelf, but the actual wiring into the panel was never a project either of us touched ourselves.

We've gone deeper elsewhere on exactly which parts of a setup are safe to do yourself and which aren't, since that line matters more than most of the marketing around these systems lets on.

If a step touches your home's permanent wiring, that's the electrician's job, not a weekend project.

The After-Storm Checklist, Minus the Bullet Points

Once the power's back and the fridge is humming at its normal pitch again, we still sit down and run what amounts to a road-trip debrief for the whole event — what worked, what didn't, what needs replacing before the next one. Did we have enough extension cords? The answer is always no. Did the kids have enough light to read by without turning the living room into a candle hazard? Usually. Half the time the real test of all this happens nowhere near our own kitchen table — plenty of storm watches have caught us walking Seawall Boulevard in Galveston with the kids, phones buzzing with alerts, while the backup system at home does its job without either of us standing there watching it.

If there's one thing four years of doing this has actually taught us, it's that the gear matters less than the habit of checking it. A generator or a battery you've never test-run is just an expensive guess about what happens during the next storm. Test it now, before you need the answer.
