Keep a NOAA Weather Radio programmed with your county's SAME code so it sounds an alarm only for warnings in your area, even overnight while your phone is on silent. Choose one that runs on AA batteries as well as wall power, and press its test button once a month to make sure it still works.

Run a portable generator only outdoors, at least 20 feet from the house with the exhaust pointed away from doors and windows, since carbon monoxide can build up indoors fast. Put battery-powered CO alarms near bedrooms, and use heavy-duty outdoor extension cords rated for the load instead of plugging into a wall outlet.

Power banks slowly lose charge in a drawer, so put a strip of tape on each with the date you last charged it and top it off every three months. Expect about two-thirds of the rated capacity: a 10,000 mAh bank refills a typical phone about twice, so size your kit to the days you might be without power.

When the power goes out, make your phone battery last: turn on low power mode, dim the screen, and close apps running in the background. With a weak signal, a phone drains fast searching for towers, so use airplane mode between check-ins and turn it back on at times your family agrees on ahead of time.

A small UPS can keep your modem and router online for hours in a blackout, and your internet provider's network often stays up longer than your home power does. Plug only those two devices into the battery side, and check the watts on each power adapter so the UPS rating covers both with room to spare.

Your car can be a backup charger: keep a 12V USB adapter and cable in the glovebox to refill phones and power banks during an outage. Run the engine only outdoors, never in a garage, and start it for about 15 minutes every hour or so of charging so you don't drain the battery you'll need to drive away.

Write key phone numbers on a paper card for every wallet and kit, since a dead phone takes its contact list with it. Pick one out-of-area relative as the family check-in point, because long-distance calls often connect when local lines are jammed. Texts use less network capacity than calls, so text first.

Get a pair of FRS walkie-talkies and agree in advance on a family channel and privacy code, plus a backup channel in case the first is busy. They need no license and work when phones don't, but in town their range is often a mile or less, so test them between your meeting spots before you count on them.

Keep a NOAA Weather Radio with a hand crank or solar panel in your kit, since it gets official alerts even when cell and internet service are down. Program it with your county's SAME code so it only sounds for warnings that affect you. Check it once a month so you know it works before you need it.

Run a portable generator outdoors only, at least 20 feet from your home, with the exhaust pointed away from doors and windows. Never run it in a garage, even with the door open. Carbon monoxide has no smell, so put fresh batteries in a CO alarm near where people sleep before outage season.

Power banks slowly lose charge in a drawer, so top yours off every three months and note the date on a strip of tape. Keep them indoors at room temperature, since heat ages lithium cells and cold cuts capacity. A 10,000 mAh bank fully recharges most phones about twice, so size your kit to your household.

When cell service is weak or down, your phone drains its battery quickly searching for a tower. Turn on airplane mode and low-power mode, dim the screen, and switch airplane mode off for a few minutes every couple of hours to send and receive messages. Used this way, a half-charged phone can last for days instead of hours.

During an outage, unplug computers, TVs, and chargers, and leave just one lamp switched on so you'll know when power returns. Restoration often comes with surges and brief flickers, so wait a few minutes after the lights steady before plugging electronics back in one at a time.

Standardize your flashlights, radios, and lanterns on one battery size, ideally AA, so every spare in the house fits every device. Store spares in their packaging away from loose metal, and take the batteries out of gear you only use in emergencies, since a leaking cell can ruin the radio you're counting on.

Write your key phone numbers on a card in your wallet and in your go-bag. If your phone dies or breaks, most people can't recall more than one or two numbers, and a borrowed phone or shelter landline is useless without them. Include an out-of-area relative, since long-distance calls often connect when local lines are jammed.

When networks jam after a disaster, send a text instead of calling. A text needs only a sliver of capacity and keeps retrying until it gets through, while a call just fails. Agree with your household now that the first message after any emergency is a short text saying where you are and whether you're okay.

If your household uses FRS walkie-talkies, choose a meeting channel and a backup now, and write both on tape stuck to each radio. Do a check-in at a set time, like the top of every hour, so nobody has to leave a radio on all day. Range is often under a mile in town, so test from the far end of your street before you count on it.

Your car is a backup power station: a quality 12V USB adapter can recharge phones and radios, but run the engine while you charge so you don't drain the starter battery. Only idle it outdoors, never in an attached garage even with the door open, and keep half a tank so you can still drive out if you need to.

Running a generator? Use a heavy outdoor-rated cord, 12 gauge or thicker for anything over 25 feet. A thin indoor cord drops voltage, which strains fridge and freezer motors, and it can overheat under a coil of slack. Unroll it fully, keep connections off wet ground, and never plug the generator into a wall outlet.

Before you buy a bigger battery, cut what's drawing on it: put your phone in airplane mode and only toggle cellular on for a few minutes each hour to check alerts. A phone hunting for a weak tower burns its battery several times faster than one sitting idle, and that one habit can turn a single charge into two days of contact.

Charge your power bank monthly and check it under load — lithium cells self-discharge, and a pack that's sat in a drawer since last spring may show four lights but die halfway through one phone charge. Plug in a phone at 50 percent and confirm it actually takes a full charge before you file it back away.

Radio silence cuts both ways: if you rely on a cell booster or mesh Wi-Fi extender, remember those need power too, so map which outlets in your house feed your backup and label them. A booster plugged into a dead circuit is just a paperweight while your phone shows one bar in the kitchen.

A small UPS on just your modem and router is one of the cheapest outage upgrades — that pair usually draws under 30 watts, so a $60 unit can hold Wi-Fi calling and alerts for hours if your ISP's lines stay live. Test it by pulling the UPS plug and timing how long you actually stay online, then label the runtime on the case.

Keep a paper copy of the phone numbers you'd actually call in an outage — power company outage line, your doctor, two neighbors — because a dead phone takes your whole contact list with it. Write them on an index card in your wallet and one taped inside a kitchen cabinet.

Test your inverter with the load you'd actually run before you need it — many cheap modified-sine units will hum a fridge or a CPAP for a minute and then trip on the startup surge. Check the surge rating, not just the continuous watts, and confirm your sensitive gear tolerates modified sine.

Tape a laminated card to your inverter or generator listing which local AM/FM stations carry emergency broadcasts, plus your county's alert frequency. A battery radio is useless if nobody in the house knows where to tune it, and scanning the dial in the dark burns batteries you'll want later.

If your generator's transfer setup is an extension cord through a window, buy the right gauge now — a 100-foot 16-gauge cord drops enough voltage to cook a fridge compressor. For runs over 50 feet on a 15A load, use 12-gauge, and unroll the cord fully so it doesn't heat up coiled on the reel.

Run your generator under real load once a season, not just an idle start — a carburetor that starts fine can still stumble when the fridge compressor kicks in. Plug in a heater or a couple of lamps for twenty minutes and watch it hold, and note the runtime you actually got per gallon so you can plan refills instead of guessing.

Program your phone's emergency contacts and one out-of-area number into a cheap prepaid backup handset, and keep it charged in the truck — when your daily phone dies or the local tower is swamped, a second device on a different carrier often still gets a text out. Texts also queue and deliver when calls won't connect.

Write the make, model, and year of your furnace, water heater, and well pump on a card taped inside the breaker panel door, along with their amp draw. When a neighbor with a generator offers to help, that card tells you in one glance what you can actually run and what to leave off.

Label both ends of every charging cable and note what each wall brick actually outputs — in an outage you'll be sharing a single 12V outlet or inverter, and hunting for the one cord that fast-charges the phone wastes daylight. A cheap USB power meter tells you in seconds which combo is doing real work.

Keep a pair of headlamps at the door and one in each vehicle — hands-free light is what actually lets you carry a kid, work a valve, or clear a step during an outage. A lantern lights a room, but a headlamp is the one that gets work done in the dark.

Test your flashlight and lantern batteries in the actual device, not with a tester — alkalines that read fine can sag under load. Standardize your gear on one battery size where you can, so a single pack of spares keeps every light running.

Two-way radios only help if everyone's on the same channel: pick one primary and one backup FRS/GMRS channel for your household, write both on the paper list, and set a check-in time like top of the hour so nobody burns batteries monitoring all day.

Cheap USB power banks often can't pass through enough current to charge a phone and run a light at once — test yours under both loads before you rely on it. Also confirm your bank actually wakes for low-draw devices; many auto-shut-off after 30 seconds on a trickle, which quietly kills overnight charging.

Keep a hand-crank or solar AM/FM radio with NOAA weather band, and actually tune in your county's weather channel once so you know the frequency and can hear it clearly indoors. Cranking blind during a warning is how people miss the first bulletin.

If you run a generator, start it monthly under real load and run the fuel dry every few months or use stabilizer — carburetors gum up faster than most people expect. Store fuel outside the house, never in the basement, and keep a spare oil bottle and air filter with the unit.

Write your key numbers on paper and tape it inside a cabinet door: the power company outage line, your propane supplier, two out-of-state contacts, and your radio channel. Phones die and cloud contacts vanish with them, and nobody memorizes numbers anymore.

Label every battery bank and radio with its full charge time and mark a "top off" date on your calendar — lithium banks self-discharge and cheap ones die on the shelf. A bank you charged eight months ago may hold nothing when you finally need it.

When the grid drops, put your phone on low-power mode and text instead of calling — a text needs a split-second of signal and a fraction of the battery a voice call burns, and it'll often push through congestion when calls won't connect. Only power up to check messages on a schedule, then back to airplane mode.

Split-charge from your car with a proper 12V/240V inverter only if it's rated above your device's surge draw — a 150W unit stalls a CPAP or a small fridge. Match the inverter to the running plus startup watts on the appliance label, and test the actual load now, not during the outage.

Keep a real flashlight or headlamp per person, not your phone. Phones burn battery you need for calls, and a dedicated light runs longer on a set of AA or AAA cells. Stash a spare pack of those batteries with each light and check them twice a year.

Agree on a single radio channel and a fixed check-in time with your household now — say, top of every hour on your GMRS or FRS channel. When you can't call, a scheduled listen-and-talk window means nobody wastes battery guessing when the others are on air.

Trickle-charge power banks off a small solar panel now, before the outage, so you're not starting a drain from empty. Note the panel's real output in cloudy weather — it's often half the label — and size your expectations to that, not the sticker.

Your car is a power bank on wheels: keep a 12V-to-USB adapter in the glovebox and confirm it charges phones and radios. Idle the engine a few minutes each hour so you top off devices without flattening the starting battery you need to drive out.

Welcome to Technician. Program your local NOAA Weather Radio frequency and test it now — it's the most reliable alert channel when cell networks are jammed.

Keep a paper list of key phone numbers. Your contacts are useless when your battery is dead and you're borrowing someone else's phone.

Label every battery bank and radio with the date you last tested it. Untested backup power is just hope with a handle.
