Quick answer: A 72-hour emergency kit should cover water (1 gallon per person per day), shelf-stable food, a light source, a way to charge phones, a basic first aid kit, and a portable radio. What a kit costs depends mostly on what you already own, so start with what is already in the house. The goal is covering the first three days after a disruption (power outage, storm, or evacuation) before help typically arrives or normal services resume.

72-Hour Emergency Kit Gear Hub
Ready.gov and the Government of Canada recommend being ready for at least 72 hours as a starting point. Power outages, winter storms, regional flooding and short-notice evacuations can hit with little warning, and some events, like ice storms and hurricanes, can last much longer. A 72-hour kit isn’t about preparing for collapse. It’s about removing the stress of those first three days so you can think clearly and help the people who depend on you.
This hub walks through exactly what to pack, what it should cost, and how to choose backup power: the single piece of gear most households get wrong.
Start with these three, then size your backup power
Most of a 72 hour kit is already in the house. These three are the pieces that are not, and each one does its job with the power out.
Hand crank weather radio. Weather alerts and a flashlight you can recharge by hand: the crank and the solar panel on the Midland ER310 top it up when the outlets are dead. Keep it in the kit, not in a drawer.
Rechargeable headlamp, two pack. Hands free light for two people; charge both from a power bank or the power station before a storm is named.
Seven gallon water container. Three days of water for two people in one jug (one gallon per person per day for drinking and sanitation, the Ready.gov figure). Fill it when a storm is named, from the tap, and store it off the floor.
Backup power is the piece most households size wrong. Size it in a minute below, then pick from the power station picks.

What Should Be in a 72-Hour Emergency Kit?
A complete kit covers five categories: water, food, light, communication, and backup power. Everything below is organized by category so you can build incrementally instead of buying everything at once. For official baseline guidance, see Ready.gov’s emergency kit checklist.
This isn’t hypothetical: a nor’easter on September 27 left more than 130,000 customers without power across the Northeast, with New Jersey and New York both declaring states of emergency, and no hurricane involved. A kit built ahead of time is what makes that kind of week manageable instead of stressful.
Water
- 1 gallon per person per day (3 gallons minimum per person for 72 hours)
- A portable water filter as backup (extends your supply if the disruption runs longer than expected)
Food
- Shelf-stable, no-cook options: protein bars, canned goods with a manual can opener, freeze-dried meals
- Plan for each person’s usual food needs, and ask a doctor or dietitian about children, older adults or anyone with a medical condition
Light & Power
- A hand-crank or battery flashlight per person
- A backup power source for phones and medical devices: see the decision framework below
Communication
- A battery or hand-crank emergency radio with NOAA weather alerts
- A written list of emergency contacts (don’t rely on phone memory alone)
First Aid & Documents
- A basic first aid kit (bandages, antiseptic, any household-specific medications)
- Copies of ID, insurance info, and emergency contacts in a waterproof bag
Quick Picks
Power for a 72-hour kit
Best for most households: Jackery Explorer 300 (292 Wh)
Enough for phones, a few lights and a radio for several days, without paying for capacity a 72-hour kit will not use.
Need to run a medical device or keep a fridge going on and off? Confirm your device’s power draw first, then look at the 1 kWh class in Power Station Options below. Short on space? A compact power bank (10,000 to 20,000 mAh) with a foldable solar panel covers phones and lights without the bulk.
How Much Backup Power Do You Actually Need?
This is the question that trips up most first-time buyers. Use this framework instead of guessing.
If you want maximum runtime →
Choose a larger-capacity station (for example the EcoFlow DELTA 3 Classic or the Jackery Explorer 1000 v2, both under Power Station Options). Best if you need to run a CPAP machine, medical device, or want to keep a fridge running intermittently.
If you want best value →
Jackery Explorer-series covers phone charging, a few lights, and a radio for multiple days without overspending on capacity you won’t use.
If you need portable/apartment-friendly →
A compact power bank (10,000 to 20,000mAh) paired with a foldable solar panel covers phone and light charging without the bulk of a full power station: ideal if storage space is limited.
If you’re planning for winter readiness →
Cold reduces battery efficiency. Store the unit indoors, not in an unheated garage or vehicle. By the makers’ spec pages (read October 17, 2026), the Jackery Explorer 1000 v2 and the EcoFlow DELTA 3 Classic both charge between 32 and 113 F and run between 14 and 113 F, while the Jackery Explorer 300 charges between 32 and 104 F and runs between 14 and 104 F.
Before you buy, verify: current price, watt-hour capacity, and recharge time directly on the product page: these specs and prices change and should be confirmed at the merchant before purchase.
Power Station Options: US & Canada
EcoFlow DELTA 3 Classic (1,024 Wh)
1,024 Wh of storage and 1,800 W of output, per the listing. That is about three and a half times the storage of the Explorer 300, a size to consider for a CPAP or a fridge cycled on and off, after you check your own device’s power draw.
Jackery Explorer 1000 v2 (1,070 Wh)
1,070 Wh of storage and 1,500 W of output, per the listing: a little more storage and a little less output than the DELTA 3 Classic. Solar panel optional.
Trying to decide between the two? See our full EcoFlow vs Jackery comparison for a deeper breakdown of charging speed, power output, and battery safety. Use the buttons above for today’s price.
Update, October 19, 2026: EcoFlow announced its TITAN Series on October 13, whole-home batteries (about 5 kWh per unit, expandable to 30 kWh) with a Smart Home Panel that backs up 10 circuits. They sit above the portable power stations in this hub and are not part of a 72-hour kit. EcoFlow says it will post final prices for every configuration on November 3, so we are not quoting a price until we can read one on EcoFlow’s own page. We have not seen Canadian availability announced.
Charging your power station safely: Follow the maker’s manual, use the cable and adapter that came with the unit, and do not charge it while you sleep. Stop using it if it gets unusually hot, swells, smells off, leaks or makes odd noises. The Seattle Fire Department’s lithium-ion battery safety page lists the same warning signs.

72-Hour Kit Scenario Fit
Apartment/urban: Prioritize compact, stackable storage: under-bed bins work well. Skip anything requiring outdoor venting.
Family with kids: Add comfort items (a favorite snack, a small toy): reduces stress for everyone during a disruption.
Vehicle kit overlap: Keep a separate, smaller version of this kit in your vehicle: see our Vehicle Emergency Kit guide for the full breakdown. Or watch the video walkthrough.
Winter readiness: Add hand warmers and an extra blanket per person; battery performance drops in cold storage.
Prefer a Ready-Built Kit?
If assembling each category above feels like more than you want to take on this week, Survival Frog sells pre-built 72-hour and emergency kits alongside individual pieces like lanterns, hand-crank radios, and long-shelf-life food: a faster starting point if you would rather buy a complete kit than build one category at a time. Verify exact kit contents and current price on their product page before buying.
Preparedness can feel heavy, especially when life is already full. You do not need to do everything today. Pick one small win: check your flashlights, set aside a little extra water, or write down your family’s meetup plan. Small steps compound fast, and future-you will be grateful you started.

Frequently Asked Questions
How much does a 72-hour emergency kit cost?
It depends on what you already own, so start by taking stock of the house. Water and food add little cost if you’re already stocking groceries; backup power is usually the largest single expense.
How much water should I store per person?
Store at least one gallon per person per day, or three gallons per person for a 72-hour kit. Add more for pets or anyone with medical needs.
What’s the difference between a 72-hour kit and a bug-out bag?
A 72-hour kit is typically stored at home for sheltering in place during an outage or storm. A bug-out bag is portable and packed for evacuation. Many households build one kit that serves both purposes.
Do I need a generator or is a portable power station enough?
For most apartment and household needs (phones, lights, a radio, occasionally a CPAP) a portable power station is enough and is safer indoors. Generators produce far more power but must run outdoors only, away from windows and doors, due to carbon monoxide risk.
How often should I rotate food and water in my kit?
Replace water you filled yourself every 6 months, follow the expiration date on store-bought water, and check shelf-stable food dates at the same time. Set a recurring reminder tied to a date you’ll remember, like daylight saving time changes.
Can I build a 72-hour kit on a tight budget?
Yes. Start with water and a flashlight: both are inexpensive and cover the two most urgent needs. Add one category per month rather than buying everything at once.
What size power station do I actually need for a 72-hour kit?
For phone charging, lights, and a radio, a smaller-capacity station (under 300Wh) is usually enough. If you need to run a medical device or want appliance backup, size up: see the decision framework above.
Is a 72-hour kit enough, or should I prepare for longer?
Ready.gov and the Government of Canada recommend being ready for at least 72 hours as a starting point. If you live somewhere prone to longer outages (rural areas, severe winter regions), consider expanding toward a 1 to 2 week supply once your 72-hour kit is complete.

Building Real Readiness, One Step at a Time
You don’t need a perfect emergency setup to become more prepared. Start with water, light, communication, and a simple 72-hour plan. Once those are covered, you can build the rest of your system (longer-term food storage, a vehicle kit, a family communication plan) with more confidence.
