Quick answer: A complete 72-hour emergency kit covers four layers, built in order: water (store one gallon per person per day for at least three days), power and light, no-cook food, and medical and hygiene supplies. Solve water first, then light and communication, then food, then first aid. This hub links current US and Canada options for each layer.

💧 How much water do you need (and what to buy)?
Plan for 1 gallon per person per day for at least 3 days (more in heat, with kids, or if you’re active). Start with water storage, then add purification as your backup layer.

🔋 How do you choose a portable power station?
If you need multi-day backup power, a portable power station is the strongest upgrade. Choose by what you must run, not by the biggest number:
- Phones, lights, Wi-Fi only: a small unit (roughly 300–600Wh) is plenty.
- CPAP, medical devices, or a mini-fridge: step up to ~1,000Wh+ and check the continuous output (W) matches the device.
- Whole-home resilience: a larger unit plus solar input for recharging during extended outages.
Compare three numbers: capacity (Wh), continuous output (W), and recharge options. Pick the smallest unit that reliably covers your must-run list.

🩹 What medical and hygiene supplies do you need?
Small injuries and poor air quality can become big problems during cleanup. Cover the basics: a practical first aid kit, masks for smoke/dust, and gloves for debris. If anyone takes prescriptions, keep a buffer supply when possible and a simple med list (name/dose).

❓ Frequently Asked Questions
What should a 72-hour emergency kit include?
At minimum: water (1 gallon per person per day for 3 days) and a purification backup, light (headlamp), a power bank, an emergency radio, no-cook food with a manual can opener, and a first aid kit with N95 masks and gloves. Add medications and copies of key documents.
How much water do I need for 72 hours?
A practical baseline is 1 gallon per person per day — about 3 gallons per person for 72 hours — covering drinking and basic hygiene. Store more for hot weather, children, pets, or larger households.
I live in an apartment — what should I buy first?
Start with water storage, then a headlamp, a power bank, and an emergency radio. Those four items solve the biggest problems in most urban outages without needing much space.
How do I choose a portable power station?
Start with what you must run (phones and lights vs. a fridge or CPAP). Compare capacity (Wh), continuous output (W), and recharge options, then choose the smallest unit that reliably covers your must-run devices.
What food is best for a 72-hour kit?
Choose no-cook, ready-to-eat calories you’ll actually eat under stress: food bars, shelf-stable meals, and familiar snacks. Keep a manual can opener if you store canned food.
How much does a 72-hour kit cost?
A basic household kit can be built for roughly $100–$250 if you start with water, light, a radio, food, and first aid. Costs rise mainly if you add a portable power station, which is an optional upgrade for longer outages.
Where can I buy a 72-hour kit in Canada?
Each item in this hub includes an Amazon.ca link for Canadian shoppers. For backup power, use the interim Amazon.ca links above until EcoFlow and Jackery Canada programs are connected.
How often should I review or replace items?
Every 6 months is a solid rhythm: test flashlights and radios, replace batteries, rotate food, and confirm medical supplies and medications are in date.
