What Should Be in a 72-Hour Emergency Kit?

When something disrupts normal life — a storm, outage, or evacuation order — the first 72 hours are when households feel the gap between “we should prepare” and “we’re ready.”

A 72-hour emergency kit is a focused set of supplies meant to cover roughly three days without normal power, stores, or services. It isn’t a full long-term pantry. It’s the bag or bin you can grab or live from while conditions stabilize.

1. Water

Aim for about one gallon per person per day for drinking and basic hygiene. For a family of four, that’s roughly 12 gallons for three days. Store in sealed containers and rotate periodically. If you use a portable filter or purification method, keep it with the kit and know how to use it before you need it.

2. Food

Choose non-perishable items that don’t need refrigeration and need little or no cooking: canned goods (with a manual can opener), nut butters, energy bars, dried fruit, and ready-to-eat meals. Include any critical specialty items (infant formula, etc.) your household needs.

3. Light and power

A reliable flashlight (and spare batteries or a rechargeable light), plus a power bank for phones, helps you stay oriented and connected. Headlamps keep hands free. Avoid relying only on phone flashlights — batteries drain fast when you’re already stressed.

4. First aid

A basic first aid kit for cuts, blisters, and minor injuries belongs in every kit. Add any prescription medications you can’t go without (with a plan to rotate them before they expire).

5. Communication and information

A written list of emergency contacts, a battery or hand-crank radio if you have one, and charged power banks help when cell networks are congested. Know your local alert systems before a crisis.

6. Warmth, hygiene, and documents

Depending on your climate: layers, blankets, or emergency blankets; hygiene supplies; copies of IDs and insurance info in a waterproof pouch; cash in small bills.

7. Go-bag vs. home kit

Some families keep a home kit in a closet or garage and a smaller go-bag for each person if they must leave quickly. Label bags and review them twice a year.

Next step

Walk through your home once and note what you already have. Fill gaps in order: water, light, first aid, then power and food. For a structured planning workbook, see our digital guide Your First 72 Hours on PrepSmart Supply, and browse first aid kits, lights, and power banks in our store when you’re ready to equip the list.

Build from your household checklist

Use our 72-hour go-bag builder to compare individual supplies, or browse emergency bags and kits and review their exact contents. Add personal needs separately; a ready-made kit may leave gaps for your household.

Compare water containers and filtration gear, first-aid supplies, and portable lighting against what you already own. A filter does not replace a stored emergency water supply.
