Emergency Kits and Supplies: Complete Guide (2026)

The Four-Kit System

Most households have zero emergency kits. Some have one. Serious preppers maintain four — and for good reason. Different emergencies hit in different places.

The four kits every household needs:

Home kit — shelter-in-place or rapid evacuation from your house
Car kit — breakdown, accident, or getting stranded far from home
Work / EDC kit — getting home on foot if the grid goes down during your commute
Go-bag — 72-hour portable kit for rapid evacuation (covered in depth in our how to build a 72-hour emergency kit guide)

This article focuses on the home kit and car kit in detail, covers fire extinguisher selection (the most overlooked item in home preparedness), reviews the top prebuilt options, and gives you a maintenance system that actually sticks.

FEMA Baseline vs. What Serious Preppers Actually Build

FEMA’s official emergency kit list is a starting point — not a finish line. Here’s the honest comparison.

FEMA Minimum (72-Hour Shelter-in-Place)

Item	FEMA Recommendation
Water	1 gallon per person per day, 3-day supply
Food	3-day supply of non-perishable items
Battery-powered or hand-crank radio	NOAA Weather Radio
Flashlight	With extra batteries
First aid kit	Basic
Whistle	To signal for help
Dust mask	N95 or improvised
Plastic sheeting + duct tape	Shelter-in-place for contamination
Moist towelettes + garbage bags	Sanitation
Wrench or pliers	Shut off utilities
Manual can opener	For canned food
Local maps	Non-digital
Cell phone + chargers	Including battery backup

This is a reasonable baseline for the average household. It will get most families through a 3-day power outage after a storm.

What it misses:

No water filtration (tablets or filter) — critical if tap water is contaminated or you need to leave
No trauma supplies (tourniquets, hemostatic gauze) — a basic first aid kit won’t stop serious bleeding
No prescription medication buffer (30-day supply target)
No backup power for medical devices
No extended food supply (the math at 3 days leaves zero margin)
Nothing for pets

Serious Prepper Additions

Level	What It Covers
FEMA baseline	72-hour outage, shelter-in-place
2-week home kit	Extended grid-down, hurricane/tornado recovery
Bug-out ready	Evacuation to secondary location up to 72 hours out
Full prepper	3-month+ self-sufficiency

The gap between FEMA minimum and a genuine 2-week kit isn’t as large as it sounds. Most of the difference is bulk food and water storage — inexpensive and easy to accumulate gradually.

Home Kit: 72-Hour Baseline Through 2-Week Extended Kit

Build in tiers. Get Tier 1 done first, then expand.

Tier 1: 72-Hour Baseline (~$150-$250)

Water:

3 gallons per person (FEMA minimum — target 1.5 gallons per person per day when possible)
Sawyer Squeeze or Sawyer Mini filter
Water purification tablets (Aquamira) as backup

Food:

6,000 calories per person of no-cook, shelf-stable food
Peanut butter, protein bars, trail mix, tuna pouches, granola, hard candy
Manual can opener

Shelter/warmth:

Wool blankets or emergency bivvy bags (one per person)
Duct tape + plastic sheeting (N95 masks, too, for air quality events)

Light and power:

LED headlamp per person + extra batteries
Lantern (battery or hand-crank)
USB battery bank (20,000 mAh minimum)
Hand-crank/solar emergency radio with NOAA weather bands

First aid:

Standard first aid kit (bandages, gauze, antiseptic, tape)
CAT tourniquet (one minimum — non-negotiable)
Israeli bandage
72-hour prescription medication supply

Documents/cash:

Copies of IDs, insurance, property documents in waterproof bag
$300-$500 cash in small bills (ATMs fail without power)
Printed emergency contact list and area map

Sanitation:

Toilet paper and garbage bags
Hand sanitizer
N95 masks (minimum 2 per person)

Tier 2: 2-Week Extended Kit (Additional ~$200-$400)

Add these to your Tier 1 baseline when extending to 14 days:

Water storage:

WaterBOB or Aquatank bathtub bladder (100-gallon emergency fill when you have advance warning of a storm)
5-gallon water storage containers (at least 2-4 per household)
Total target: 2 gallons per person per day x 14 days

Food:

14-day supply of shelf-stable food: canned goods, freeze-dried meals, rice, beans, pasta, cooking oil
Camp stove + fuel canisters (at least 8 oz per day of cooking)
Budget: $100-$200 for 2 people at 2,000 calories/day

Power:

Portable power station (500-1,000 Wh) or generator + fuel
Battery-operated or propane lantern
Car charger for phones and battery banks

Medical:

30-day prescription medication supply (requires advance planning with your doctor)
Hemostatic gauze and chest seal for trauma response
Blood pressure cuff if household has hypertension risk

Climate-specific additions:

Climate	Add to Your Kit
Hurricane zones	Marine-grade waterproof containers, tarps, NOAA marine radio
Tornado corridor	Helmet (bicycle or motorcycle), sturdy shoes by the bed, interior room supplies
Wildfire regions	N95/P100 masks (N95 minimum), air quality monitor, go-bags staged by the door
Winter storm risk	Extra warm layers, hand/toe warmers, backup heating source (propane heater + CO detector)

Car Emergency Kit: Year-Round and Winter Builds

Your car kit handles three scenarios: mechanical breakdown, accident response, and getting stranded far from home. The items that matter differ by climate and season.

Year-Round Car Kit (~$75-$150)

Jump starting:

Lithium jump starter pack (NOCO Boost Plus or similar, 1,000+ amp) — not jumper cables
Why: A jump starter lets you self-recover without flagging down another vehicle. Most modern lithium units also charge phones and power USB devices.
Jumper cables are a fallback only — useless if no other cars are present.

Signaling and safety:

LED road flares (3-4) — not traditional flares
Why: Traditional emergency flares are one-time-use, ignite hot, and require a working lighter. LED road flares are reusable, weatherproof, no ignition needed, and visible from over a mile in daylight. Cheaper over time.
High-visibility safety vest

Emergency response:

Glass breaker and seatbelt cutter (spring-loaded, not hammer — keep on the seat, not in the trunk)
First aid kit (compact but include a tourniquet)
Emergency blanket (two minimum — SOL or similar mylar/reflective type)

Tools:

Tire pressure gauge
Fix-a-Flat or portable tire inflator with 12V compressor
Basic tool kit: screwdrivers, pliers, zip ties, duct tape, electrical tape
Tow strap

Sustenance:

2 liters of water (rotate every 6 months — heat cycles degrade plastic bottles)
2,400 calorie emergency food bar (Datrex or Mainstay — formulated for long shelf life)
Spare phone charger (car adapter + cable)

Documents:

Printed roadside assistance card
Emergency contact list
Basic local area map

Winter Car Kit Additions (~$40-$80)

Cold-weather additions belong in the car from November through March (or year-round if you live in snow country):

Ice scraper and snow brush (full-length — the ones that actually reach the roof)
Jumper cables as backup to your jump starter (in case another motorist needs them)
Traction mats (TRAC-GRABBER or similar) — sand or cat litter works in a pinch
Spare warm layers: wool hat, gloves, wool socks, insulated jacket (not just a light jacket — something rated for temps you’d face if stranded overnight)
Chemical hand and toe warmers (10+ pairs)
Small folding shovel
Extra washer fluid rated for your temperatures
Candle and matches (a single candle inside a car can raise interior temperature meaningfully in an emergency)

Stranded overnight rule: If you’re stranded in winter, stay with the vehicle unless you can clearly see shelter. A car is a better windbreak and easier to find than a person on foot. Run the engine in short intervals (10 minutes per hour), crack a window, and keep the exhaust pipe clear of snow.

Fire Extinguisher for Home: What to Buy and How to Use It

A fire extinguisher is the single most underestimated piece of emergency equipment. A 10-second response to a kitchen fire can prevent total home loss. A response 30 seconds later may accomplish nothing.

Class Types

Class	Fights	Common Source
A	Ordinary combustibles (wood, paper, cloth)	Living rooms, bedrooms
B	Flammable liquids (gasoline, grease, oil)	Garages, workshops
C	Electrical fires	Kitchen appliances, wiring
K	Commercial cooking oil fires	Commercial kitchens only
ABC	All three above	Best for homes

What to buy: A 2.5 to 5 lb ABC dry chemical extinguisher covers everything most households will encounter. Kidde and First Alert both make reliable residential units for $30-$70.

Class K is not needed for most homes. It’s designed for the pressurized oil in commercial deep fryers. A regular grease fire on a home stovetop is a Class B fire — ABC handles it.

Placement

Location	Rationale
Kitchen (wall-mounted near exit)	Highest fire risk room in the home
Garage	Fuel, oil, power tools
Furnace/utility room	Mechanical ignition risk
Each floor of a multi-story home	30-second rule: extinguisher within 30 seconds of any room

Mount extinguishers in the open, at eye level, near exits — not under the sink or in a closet. You don’t have time to hunt for one.

How to Check Your Extinguisher

Check the pressure gauge monthly — needle should be in the green zone
Look for visible damage: cracked hose, corroded pin, missing safety seal
Shake dry chemical units monthly to prevent powder from compacting
Replace or recharge after any discharge, even partial
Replace entirely every 10-12 years (check the manufacture date on the label)

When to Use vs. When to Get Out

Use a fire extinguisher only if all four conditions are true:

Everyone else has exited or is exiting
You have a clear escape path behind you
The fire is small and contained (wastebasket-sized or smaller)
You know what’s burning (don’t use water or ABC on a live electrical fire)

If the fire has spread to more than one item, is near the ceiling, or you cannot see your exit through the smoke — get out. No possession is worth your life.

PASS technique: Pull the pin, Aim at the base of the fire, Squeeze the handle, Sweep side to side.

Prebuilt Kit Review: Ready America and Sustain Supply

If you need something functional right now and don’t have time to build your own, two brands consistently outperform the rest of the crowded prebuilt market.

Ready America 72-Hour Emergency Kit (2-Person)

Price: ~$60-$80 What’s included: Food bars, water pouches, emergency ponchos, space blankets, glow sticks, dust masks, first aid kit, hand-crank flashlight, whistle, hygiene kit Honest assessment: Adequate for one to two days of low-intensity disruption. The food bars are calorie-sufficient but borderline palatable. The “first aid kit” is a basic adhesive bandage collection — no tourniquet, no trauma supplies. The dust masks are not N95. The water pouches (4 oz each) are frustratingly small. What’s missing: Water filter, trauma first aid, prescription medications, power bank, communication, documents, cash, anything specific to your household. Verdict: A legitimate starting point if you have nothing. Supplement immediately with a water filter, a tourniquet, and a USB power bank.

Sustain Supply Co. Comfort2 Kit (2-Person, 72-Hour)

Price: ~$180-$220 What’s included: Higher-calorie food bars, larger water pouches, better first aid kit, emergency bivy, emergency ponchos, hand-crank radio/flashlight, N95 masks, dust masks, gloves, hygiene supplies Honest assessment: The best mid-range prebuilt option. Food calories are accurately stated and the packaging is quality. The N95 masks are a genuine inclusion most competitors skip. The emergency radio is functional. What’s missing: Water filtration, trauma supplies (still no tourniquet), power bank, documents, medications, climate-specific items. Verdict: A solid 60% solution. You’ll still need to add filtration, trauma first aid, medications, and personalized items. But you’re starting from a better base than most prebuilts.

DIY vs. Prebuilt: Why DIY Usually Wins

Factor	DIY	Prebuilt
Quality	You control every component	Often lowest-viable to hit price point
Customization	Climate, household, medical needs	One-size-fits-all
Cost	Usually equal or less	$80-$300 for incomplete coverage
Time	2-4 hours to source and pack	10 minutes to order
Completeness	You build to your threat model	Misses trauma, filtration, medications

The case for DIY: Every household is different. A kit for a family in Phoenix during monsoon season looks nothing like one for a household in Minnesota in February. A diabetic insulin-dependent family member requires refrigeration planning that no prebuilt kit addresses. A nursing infant needs formula. A large-breed dog needs 2+ liters of water per day.

When prebuilt makes sense: You need something functional this week and have nothing. Buy a Sustain Supply kit, then spend the next 30 days rounding it out.

Kit Maintenance: Rotation Schedule and Annual Inspection

The best-built kit degrades into a liability if you ignore it. Expired food, dead batteries, and outdated documents can fail you at the worst moment.

Every 6 Months (Tie to Daylight Saving Time Changes)

Replace expired food items (check all dates — bars often expire in 2-5 years)
Check water storage (replace bottled water that’s been in a hot car; replace home storage every 6-12 months)
Test all batteries and electronics
Check medication expiration dates — request early refills to build a buffer
Verify fire extinguisher gauge is in green zone

Annually (Full Inspection)

Fully unpack every kit — remove, inspect, and repack
Update documents (IDs, insurance, emergency contacts)
Swap seasonal gear (car kit: rotate winter-to-summer and back)
Test your radio on actual weather bands
Verify jump starter is fully charged and holds charge
Update cash — small bills only, replenish if used
Recheck fire extinguisher: no corrosion, pin intact, hose uncracked
Review your household’s situation: new medications, new pets, changes in family size

Expiration Reference Table

Item	Typical Shelf Life
Water (sealed commercial bottles)	1-2 years (rotate for taste, not safety)
Emergency food bars (Mainstay, Datrex)	5 years
Freeze-dried meals (Mountain House)	30 years
Canned goods	2-5 years (check labels)
Medications (OTC)	Check label — most 2-3 years
Batteries (alkaline)	5-10 years sealed
Fire extinguisher	10-12 years (check manufacture date)
Water purification tablets	4-5 years sealed

Tracking system: A simple spreadsheet beats trying to remember. Log each item, quantity, and expiration date. Sort by expiration date. Review monthly. Rotate items into everyday use before they expire (granola bars, canned goods, medications) rather than throwing away usable supplies.

Emergency Kit Quick-Start Checklist

If you’re starting from zero, build in this order:

Week 1 ($50-$80):

Water: 3 gallons per person + Sawyer Squeeze filter + Aquamira tablets
Food: 3-day supply of bars, pouches, nuts, peanut butter
Light: LED headlamp per person + extra batteries

Week 2 ($60-$100):

First aid: CAT tourniquet + Israeli bandage + basic first aid kit
Communication: Hand-crank NOAA weather radio
Power: 20,000 mAh USB battery bank

Week 3 ($40-$80):

Documents: Waterproof bag with ID copies, insurance, cash ($300 minimum)
Car kit: Jump starter + LED road flares + emergency blankets
Fire safety: ABC extinguisher for kitchen (mount it immediately)

Month 2 ($100-$200):

Extend food and water to 2-week supply
Add 30-day prescription medication buffer
Build or buy go-bag for rapid evacuation

A household with nothing that completes Weeks 1-3 is dramatically better prepared than 90% of their neighbors. Don’t let perfect be the enemy of good enough to start.

Frequently Asked Questions

What should be in a basic emergency kit?

FEMA's baseline: 1 gallon of water per person per day for 3 days, 3-day food supply, flashlight, NOAA weather radio, first aid kit, extra batteries, whistle, dust mask, plastic sheeting and duct tape, moist towelettes and garbage bags, wrench or pliers, manual can opener, local maps, and a cell phone with chargers. A serious prepper adds a water filter, trauma supplies, medications, a go-bag, and a 2-week food reserve.

What is the best car emergency kit?

A year-round car kit should include a jump starter (not jumper cables), LED road flares, emergency blanket, first aid kit, glass breaker and seatbelt cutter, basic tools, water and food rations, and a phone charger. Winter additions: ice scraper, traction mats, extra warm layers, and hand warmers. For a full build list, see the car kit section of this article.

What is a hurricane emergency kit?

A hurricane kit is a home shelter-in-place kit built for extended grid-down scenarios. Key additions over a standard kit: 2 weeks of water (14 gallons per person), a generator or solar power station, tarps and plywood for window boarding, extra prescription medications (30-day supply), a portable weather radio, and important documents in waterproof storage. A cash reserve is critical because card readers fail without power.

What kind of fire extinguisher should I have at home?

A 2.5 to 5 lb ABC dry chemical extinguisher handles the three most common home fire types: ordinary combustibles (A), flammable liquids (B), and electrical (C). Mount one in the kitchen, one in the garage, and one near the furnace or utility room. Class K extinguishers are for commercial deep-fat fryers — not needed in most homes. Check the pressure gauge monthly and replace or recharge after any use.

Should I buy a prebuilt emergency kit or build my own?

DIY is almost always better. Prebuilt kits use low-quality components to hit a price point, omit items specific to your household, and can't account for dietary restrictions, medical needs, or your climate. Building your own costs roughly the same or less while giving you better gear and full customization. Use a prebuilt only as a temporary baseline if you need something right now.

How often should I rotate emergency kit supplies?

Every 6 months: replace expiring food and water, check medication dates, test electronics. Annually: full unpack and inspection, update documents, swap seasonal gear. The easiest system is to tie rotations to daylight saving time changes — same day you change smoke detector batteries.
