Quick answer: A 72-hour emergency kit holds what one person needs to get through three days without power, running water or stores: 3 gallons of water plus a way to treat more, 3 days of no-cook or just-add-water food (about 6,000 calories), a light, a battery or crank radio, a charged power bank, a first aid kit, prescription medicine, warmth, sanitation supplies, cash and copies of key documents. Build one per person and keep it where you can grab it in two minutes.
Seventy-two hours is the number almost every government uses, because that is how long it can take for emergency services to reach everyone after a major disaster. In October 2026 the UK told every household to be ready for three days without essential services, joining the EU's 72-hour recommendation and long-standing US advice from Ready.gov. This checklist combines them into one list you can shop from today.

What Governments Actually Recommend
| Authority | How long | Headline advice |
| FEMA / Ready.gov (US) | Several days | Water (1 gallon a person a day), food, radio, flashlight, first aid, batteries, whistle, local maps, phone charger |
| UK Be Ready (Oct 2026) | 3 days | Water, food that needs no cooking or fridge, torch, radio, power bank, medicines, cash |
| European Commission | At least 72 hours | Water, food, medicine, flashlight, power bank, radio, cash, documents |

The lists agree on the essentials. Where they differ is how long, not what. Start at 72 hours, then extend toward a week or a month with our 30-day supply plan.
The Complete 72-Hour Kit Checklist
Quantities are per person. Products are examples from our range; anything equivalent works.
Water
- 3 gallons of drinking water (one a day, per FEMA). For a go bag, carry 1–2 liters and a filter instead.
- A filter or purifier: the Sawyer Squeeze (0.1 micron, 3 oz filter), the LifeStraw Peak Series Straw (up to 4,000 L) or, if viruses are a concern, the Grayl GeoPress Purifier.
- Backup chemical treatment: Coghlans Emergency Drinking Water Tablets (2 tablets a quart) or Aquamira drops.
Food
- About 6,000 calories of food you can eat with little or no cooking.
- The ReadyWise 72 Hour Emergency Food Supply packs 6,780 calories (over 2,200 a day) into one stackable box with up to a 25-year shelf life. Pouches need hot water.
- Add no-cook food: nut butter, crackers, protein bars, dried fruit, canned meals with pull-tab lids.
- A way to heat water if you rely on freeze-dried food, plus a spoon and a cup.
Light, power and communication
- A headlamp, so your hands stay free: the Dark Energy Oracle (900 lumens, up to 50 hours, IP66).
- A charged power bank: the Dark Energy Poseidon Pro (10,200 mAh) holds its charge for years thanks to low idle drain, and is IP68 waterproof.
- A radio for news when phones and internet are down: the ETON Elite Traveler (AM/FM/LW/SW, runs on 4 AA batteries).
- Spare batteries for anything that is not rechargeable, and charging cables.
- A whistle to signal for help.
First aid and health
- A real first aid kit: the My Medic MyFAK Sidekick for a bag, or the MyFAK for the home.
- Severe bleeding control: a tourniquet and pressure dressing, as in the NAR RED Kit.
- At least 3 days of prescription medicine (7 is better), glasses, hearing-aid batteries.
- Masks, hand sanitizer, wet wipes.
Warmth and shelter
- An emergency thermal bivy or compact emergency blanket per person.
- A warm layer, a hat, gloves and sturdy shoes.
- A rain poncho or trash bags.
- A way to start a fire if you might be outdoors: the Zippo Emergency Fire Kit.
Sanitation
- Toilet paper, heavy trash bags and ties, feminine supplies, a small towel, toothbrush and toothpaste.
Documents, money and tools
- Copies of IDs, insurance policies, prescriptions and a contact list on paper, in a waterproof bag such as the SLNT Waterproof Faraday Phone Bag.
- Cash in small bills.
- A multi-tool, duct tape, a local paper map and spare keys.

Extras for Babies, Older Adults and Pets
| Who | Add to the kit |
| Infants | Ready-to-feed formula (no water needed), bottles, diapers, wipes, rash cream, a change of clothes |
| Children | Comfort item, games, snacks they like, a family photo and contact card in their pocket |
| Older adults | 7 days of medicine, a medication list, mobility aids, spare glasses, hearing-aid batteries |
| People on medical devices | A backup power plan for CPAP, oxygen or refrigerated medicine; see our grid outage guide |
| Pets | 3 days of food and water, a leash or carrier, vaccination records and a photo (Ready.gov pets) |
Home Kit vs Go Bag vs Car Kit
| Kit | Where it lives | Focus |
| Home kit | A closet or garage shelf | Shelter in place: more water, more food, power for appliances |
| Go bag | By the door, one per person | Evacuation: light, filter instead of stored water, documents, 72 hours of food |
| Car kit | In the trunk | Getting home: water, snacks, blanket, flashlight, jumper cables, first aid |
For go bags, see our complete bug out bag checklist; for sheltering at home, our bug-in guide; for storms, our 72-hour hurricane checklist.
Build It or Buy It?
Building your own kit lets you pick better individual items. A ready-made kit gets you covered today. A good middle path is a ready-made core plus your own water, medicine and documents.
- Uncharted SEVENTY2 1-Person Survival System: 24 items for shelter, water, fire, food, first aid and communication in a waterproof 32 L pack (11 lb).
- Uncharted SEVENTY2 Core: the same approach at a lower price.
- SEVENTY2.0 Pro for two people.
- Browse all of our survival kits and bags.
How to Pack It
- Heavy items low and close to your back: water and food against the spine, near the hip belt.
- Things you need fast on top or outside: headlamp, first aid, rain gear, water filter.
- Group by use in labeled bags: a water bag, a food bag, a first aid bag, a documents bag. You can find anything in the dark.
- Waterproof the critical items: documents, medicine and electronics in dry bags. A SLNT Waterproof Faraday Dry Bag does both jobs.
- Keep weight sensible: an adult go bag should usually be under about 20–25 pounds. If it is heavier, swap stored water for a filter.
- Use a bag you can actually carry: padded straps and a hip belt matter more than a tactical look.
Keep It Ready: A Six-Month Routine
- Twice a year (when the clocks change), check expiration dates on food, water, medicine and batteries.
- Recharge power banks and lights, even though good ones hold a charge for a long time.
- Update clothing for the season and children's sizes.
- Refresh cash, documents and contact lists.
- Practice: can everyone in the house find the kits in the dark?
Common Questions
What is a 72-hour kit?
A set of supplies that lets one person get through three days without outside help: water, food, light, communication, first aid, warmth, sanitation and documents.
How much water goes in a 72-hour kit?
Three gallons per person for a home kit (one gallon a day). A go bag usually carries 1–2 liters plus a water filter, because 3 gallons weighs about 25 pounds.
How many calories should a 72-hour kit have?
Around 2,000 calories a person a day, so about 6,000 for three days. The ReadyWise 72-hour box provides 6,780.
Do I need a separate kit for each person?
Yes. Quantities scale per person, and everyone should be able to grab their own bag.
Where should I keep my 72-hour kit?
Somewhere cool, dry and easy to reach on the way out: a hall closet near the main exit is ideal. Keep a smaller kit in each car.
Is 72 hours enough?
It is the minimum. Sweden recommends at least a week and Germany up to 10 days. Use our 30-day plan to build beyond it.
