Most 72-hour kits are designed for a house: 5-gallon jugs, a duffel that needs a floor, a radio that lives in the garage.
If you rent, you do not have that floor. You have a closet.
What actually matters in a first apartment when the power dies:
Water you can lift and store on a shelf
Food that does not need a stove
Light that is not your phone
A crank radio so you are not guessing
First aid that is not a travel pack from a drugstore
One fire-safe pouch for the lease, IDs, and insurance — the papers you cannot replace at 2am
Skip the bunker aesthetic. Skip the 30-day bucket. You need 72 hours in a box that fits where you actually live.
That is the kit we built.
