Probability-weighted prep

Audit Your Preps by Probability, Not by Catalog.

Most households do not need a theatrical woodland ruck first. They need water, working alarms, boring food, light, cash, documents, prescriptions, a plan, and enough backup power to keep the critical loads alive.

US-centric program names; the probability method and kit math travel globally. Last verified: 2026-07-05.

The Audit Table: Catalog vs. Reality

Verdicts are probability-weighted. "Buy" means it solves common emergencies cheaply. "Skills first" means the item is weak without practice.

Prices: US retail checks, Jul 2026
Stored Water
Buy

Purpose: the prep that matters before filtration. Example: 4 people x 14 days x 1 gal = 56 gal minimum; Red Cross uses 2-week home guidance, so double for cooking/sanitation if space allows.

$0-$80 | Gotcha: filters do not help if no water is available.
Squeeze / Gravity Filter
Buy

Purpose: make suspect water safer during travel or infrastructure advisories. Sawyer-class filters are 0.1 micron absolute and current retail is about $34-$46.

3 oz | $34-$46 | Not for chemical contamination.
Purification Tablets
Buy cheap

Purpose: pocket backup when boiling is unavailable. Example: one strip in a go-bag plus a metal bottle gives a second method.

$8-$15 | Gotcha: contact time and taste matter.
Pantry Deepening
Buy

Purpose: store what you already cook. Rice, beans, oats, and peanut butter currently price near $0.35-$0.95 per 1,000 kcal using Walmart prices and USDA calories.

Rotate monthly | Gotcha: fuel and can opener count.
Freeze-Dried Buckets
Niche

Purpose: light evacuation food or long shelf-life hedge, not the first 2-week home answer. A ReadyWise direct kit checked at about $11.40 per 1,000 kcal; staples are far cheaper.

Use when weight/shelf life beats price.
Manual Can Opener
Buy

Purpose: unlock the food you already own. Example: one in the kitchen, one taped inside the pantry tote.

$6-$15 | Failure mode: electric-only kitchens.
Headlamps
Buy

Purpose: hands-free light for breakers, stairs, diapers, toilets, and repairs. Example: one per adult plus spare batteries.

$15-$35 | Better than candle fire risk.
Power Banks
Buy

Purpose: keep phones, radios, and small medical devices alive. Example: two 20,000 mAh USB-C banks cover phones for several days.

$20-$45 each | Recharge quarterly.
2-4 kW Inverter Generator
Buy cheap

Purpose: run essentials after watt math. A Honda 2.2 kW inverter was $1,199 at Home Depot; cheaper brands exist, but compare running watts, CO shutoff, and fuel.

$500-$1,300 | Never indoors.
LiFePO4 Power Station
Buy cheap

Purpose: indoor-safe quiet power for apartments, CPAP, routers, and phones. Current official sale examples: EcoFlow 2048 Wh at $829 and Jackery 2042 Wh at $899.

~$0.40-$0.44/Wh | Cannot refuel like gas.
NOAA Weather Radio
Buy

Purpose: receive official warnings when internet is down. NOAA Weather Radio broadcasts watches, warnings, forecasts, and hazard information 24/7.

$25-$50 | Program SAME alerts if available.
Ham Handheld
Skills first

Purpose: local comms only if you know repeaters, power, etiquette, and legal limits. The radio is cheap; the ARRL 2026 exam fee is $15 and FCC application fee is $35.

$25-$60 radio | Link: Technician study.
Offline Maps + Contact Plan
Buy

Purpose: route without cell data and reduce family panic. Example: download county/state maps today and name one out-of-state check-in contact.

Free | Rehearse, or it is not a plan.
Prescription Buffer
Buy

Purpose: keep chronic conditions from becoming the emergency. Example: ask for 90-day fills, vacation override rules, or a 14-day reserve.

Costs negotiation | Rotate oldest first.
Tourniquet / IFAK
Skills first

Purpose: severe bleeding control after training. Stop the Bleed's online course is free and more than 5 million people have been trained through ACS materials.

$30-$90 | Untrained belt gear is cosplay.
CO + Smoke Alarms
Buy

Purpose: prevent the emergency your generator can create. CPSC says nearly 100 people die yearly from portable-generator CO poisoning; alarms go on every level and outside sleeping areas.

$20-$60 | Test monthly.
ABC Extinguisher
Buy

Purpose: stop small fires early. Example: 5 lb ABC near kitchen exit and garage, mounted, gauge visible, household watches PASS training video.

$35-$70 | Do not fight spreading fire.
Cash + Documents
Buy

Purpose: survive card-network outages and evacuation bureaucracy. Example: $200-$500 in small bills plus IDs, policies, deeds, medication list, contacts.

Waterproof pouch | Store copies separately.
Insurance Adequacy
Buy

Purpose: transfer the six-figure tail risk. Example: check homeowners/renters, flood exclusion, deductible, replacement cost, and liability limits.

Highest-EV "gear" for many households.
Plate Carrier / Chest Rig
Cosplay

Purpose: legitimate for some jobs and training contexts. For household emergencies, it loses to fuel, documents, water, and hotel money.

$300-$1,200 | Scenario mismatch.
Gas Mask
Cosplay

Purpose: narrow threat, fit, filter, and training problem. Without a known contaminant, sealed fit, current filters, and escape plan, it is decoration.

$150-$500 | Wrong filter = false confidence.
$300 Tactical Flashlight
Buy cheap

Purpose: light. A headlamp and lantern solve outages better for most people because they leave both hands free and illuminate rooms.

$20 answer beats luxury lumen wars.

Generator CO Rule: outside only, 20+ ft from the house, exhaust away.

CPSC's Feb. 19, 2026 safety release says portable generator CO poisoning can kill in minutes and averages nearly 100 US deaths per year. Opening windows or using fans is not ventilation. Use a transfer switch or direct appliance cords; never backfeed a wall outlet.

How to Prepare for a Power Outage

Do these before shopping: charge phones and banks, freeze water bottles, set fridge/freezer to coldest safe settings, fill containers, move meds to a cooler plan, download maps, and choose one room for thermal control.

Watt math beats generator marketing. Use running watts for what stays on, then add the largest single starting surge. Measure your own appliances with a plug meter whenever possible.

Example Essential Load

Energy Star fridge/freezer132-192 W run / 1,200 W start
Gas furnace blower300-700 W run
CPAP, no humidifier30-60 W typical
Phones, router, LED lamps50-150 W
Microwave or kettle1,000-1,500 W, run briefly

Decision: a 2-4 kW inverter unit covers the realistic list for many homes if you cycle loads. A 12 kW standby system is comfort and convenience, not baseline preparedness.

Generator vs. Power Station

Apartment / indoor-safePower station
Multi-day fridge + fuel accessGenerator
CPAP / phones / routerPower station
Gas furnace blowerEither, if sized
Central AC / electric heatUsually not realistic

Gotcha: power stations advertise surge and "boost" modes. Size by continuous output and usable watt-hours, not the largest number on the box.

The 72-Hour Evacuation Bag

Assume car-based evacuation to a hotel, relative, shelter, or staging area. Target under about 20 lb per adult. The bag is bureaucracy, health, power, clothing, and morale.

Cosplay contrast: a 60-lb woods ruck is optimized for the least likely version of leaving home. Most evacuations are paperwork, traffic, pets, fuel, chargers, medication, and sleeping somewhere with rules.

The Two-Week Home Kit

Shelter-in-place is a system: water, food, power/light, heat/cool, sanitation, meds, comms, cash, documents. Apartments can do this with under-bed water and a closet-shelf pantry audit.

Mostly-free version: cleaned containers, pantry deepening, existing blankets, documents, cash discipline. Buy-it-all version: roughly $300-$600 before generator, depending on household size and storage choices.

Common Mistakes

These fail in ordinary emergencies, not just extreme ones.

Buying the fantasy tail first
If the CO alarm has no battery, the plate carrier is not preparedness. Finish water, alarms, meds, cash, documents, insurance, light, and comms first.
Food you never cook
Store what you eat. Run a pantry weekend: no shopping, no delivery, cook only the stored food, then fix the gaps.
Generator after the storm starts
Late purchase means no fuel, no cords, no transfer switch, no maintenance, and dangerous improvisation. Test before weather.
All preps in one place
Basement flood takes the flood kit. Split documents, water, cash, car kit, and bag so one local failure does not erase everything.
Gear still boxed
Unboxed during the event means missing adapters, dead batteries, wrong fuel, and no muscle memory. Do a 48-hour shakedown.
Prescription buffer ignored
Medical continuity is boring and hard because it involves doctors and insurance. That is exactly why it outranks new gear.
Prepping alone
Neighbors notice smoke, share tools, check on kids and elders, and relay local facts. Isolation is a fragility.
Aesthetics replacing audit
Matching pouches do not matter if you cannot name your top five emergencies, quantities, shelf lives, and failure modes.
