72-Hour No-Panic Home Emergency Kit
One practical kit that covers food, water, lighting, first aid, documents, and device charging for the first 3 days.
Quick answer
What should be in a 72-hour emergency kit?
A 72-hour kit needs water (1 gallon per person per day), 3 days of no-cook food, flashlights with spare batteries, a phone power bank, a first aid kit, needed medications, and copies of key documents. Ready.gov lists these as the core of any emergency kit. Build it from what you already own first, then fill the gaps.

What the first 72 hours usually look like
Most emergencies are not movie scenes. They look like a dark house, a dead phone, and a fridge you are afraid to open. Help systems work, but they get busy. Federal guidance at Ready.gov asks every household to cover its own basics for at least 3 days.
That is the whole job of this kit. Not bunkers. Not camo. Just 3 calm days for the people in your home.
The water and food math
Water comes first. Store 1 gallon per person per day, so a family of 4 needs 12 gallons for 3 days. Pets need water too. A dog drinks about 1 ounce per pound of body weight each day.
For food, pick things you can eat with no cooking and no fridge. Canned meals, peanut butter, crackers, dried fruit, and shelf-stable milk all work. A 72-hour food kit is the faster path: one box, sealed, with a long shelf life. Just check how much water its meals need before you rely on it.
Light and power, without the guesswork
One flashlight per person, plus spare batteries, is the floor. A headlamp beats a flashlight when your hands are full. For phones, a charged power bank covers about 3 to 5 phone charges depending on its size.
Candles are a light source of last resort. They cause house fires every year, so battery light comes first. If you use a long-burn emergency candle, keep it on a plate, away from anything that burns, and never leave it alone in a room.
The document grab folder
When people evacuate, documents are what they wish they had grabbed. Make one folder now: copies of IDs, insurance cards, a list of medications with doses, key phone numbers on paper, and a little cash in small bills.
Keep it in a zip bag inside the kit. Take photos of each page and store them on your phone too.
- 1Copy IDs, insurance cards, and your medication list.
- 2Write 5 key phone numbers on paper. Phones die.
- 3Add $40 to $100 in small bills.
- 4Seal it all in a zip bag inside the kit.
The 30-minute build
You can build most of this kit tonight from things you already own. Put it all in one tub or duffel so nobody has to hunt in the dark.
- 1Pick one container and one closet shelf everyone knows.
- 2Add water first: 1 gallon per person per day, 3 days minimum.
- 3Add 3 days of no-cook food and a manual can opener.
- 4Add flashlights, batteries, power bank, first aid kit, and medications.
- 5Add the document folder, a whistle, and warm layers.
- 6Put a reminder in your phone to recheck the kit every 6 months.
What to upgrade next
Once the 72-hour layer exists, stop and breathe. You are ahead of most households. The next two upgrades that matter are water filtration (so stored water is not your only option) and a bigger battery for phones, lights, and fans.
Our water storage guide and backup power guide walk both upgrades in the same calm order.

Ready Hour 72-Hour Survival Food Kit
My Patriot Supply
- Best fit
- Covering the food layer in one sealed box
- Why it helps
- Three days of add-water meals with a long shelf life, so you skip the canned-goods puzzle. It matches this checklist one for one.
- When not to buy
- Skip it if your pantry already holds 3 days of no-cook food you actually eat, or if you cannot store extra water for the meals.
Alexapure Pitcher Water Filter
My Patriot Supply
- Best fit
- Renters and small kitchens that need a first water backup
- Why it helps
- A filter pitcher gives you a second water option beyond stored jugs, and you can use it every day so it never sits wasted.
- When not to buy
- Not the tool for untreated outdoor water. If you want whole-family filtration for long outages, look at a gravity system instead.
65W Power Bank with 15W Solar Panel
My Patriot Supply
- Best fit
- Keeping phones alive through a multi-day outage
- Why it helps
- Charges phones several times over and tops itself up from its solar panel in a window or backyard when the grid is down.
- When not to buy
- Skip it if you need to run a CPAP or fridge. That is solar-generator territory, not power-bank territory.
Ready Hour 100-Hour Candle (3-pack)
Emergency Essentials
- Best fit
- Quiet backup light that stores for years
- Why it helps
- One candle burns about 100 hours, so a 3-pack covers many outages. No batteries to rotate.
- When not to buy
- Never as a heat source, and not for homes where open flame is a bad idea. Battery lanterns first if you have kids or pets.
Medical & First Aid Kits Collection
My Patriot Supply
- Best fit
- Filling the first aid slot without building a kit from scratch
- Why it helps
- Pre-built kits cover cuts, burns, and blisters in one purchase. Add your own medications and you are done.
- When not to buy
- If you already own a kit, restock it instead. A second untouched kit helps nobody.

Common questions
How much does a 72-hour kit cost to build?
If you start with what you own, often under $150. Water can be tap water in food-safe containers. The usual paid gaps are a power bank, a first aid kit, and shelf-stable food.
Where should I store the kit?
One spot everyone in the house knows, on the path you would use to leave. A hall closet or garage shelf works. Avoid hot attics and damp corners, both are hard on food and batteries.
How often should I check the kit?
Every 6 months. Check food dates, swap water, test flashlights, and recharge the power bank. Tie it to the clock change so you never have to remember a date.
Is a bought kit better than building my own?
A bought kit is faster, and a built kit fits your family better. The honest answer is both: buy the food core, then add your own documents, medications, and comfort items.
