Stock your kit before you need it.
Answer a short questionnaire about your household. You get a practical supply list with quantities, and a shopping link on every line.
Answer 3 quick questions. No sign-up required.
Things to consider in advance.
Water
What happens when the water runs out
You can go weeks without food, but a household without clean water starts falling apart by day 2. Plan the gallons before the tap quits.
Duration
A kit that ends on day four
Most short plans are fine until the outage outlasts them. A long plan you never buy leaves you in the same spot as no plan.
Food
Food you can't actually eat
A counted food reserve only works if you look closely at how those calories are prepared, and whether anyone in the house can eat them.
Power
The second night with the lights off
Most outage injuries are ordinary (dark stairs, bruises, candles), but by night 2 a dead phone and no room light make everything harder.
