Glow sticks
A safe backup light source for kids' rooms
Communication & information
Battery or hand-crank radio

Power & charging
Battery power station
Keeps a router, fridge, CPAP, and devices running — the single highest-impact item on this list for anything longer than a few hours
Solar panel (if pairing with a power station)
Recharges the battery without needing the grid back up or a car to run to a gas station
Charging cables for every device
Stored with the power station, not scattered around the house
First aid & medical
Basic first aid kit
Bandages, antiseptic, pain relievers, any allergy medication
7-day supply of prescription medications
Rotate stock so nothing expires unused
Backup power for medical devices
CPAP, oxygen concentrators, and similar equipment — check the device's wattage against your power station's output
Safety

Plug-in-only detectors go dark exactly when you need them most
Fire extinguisher
Especially important if anyone in the house uses candles or a gas stove during an outage
Whistle

Small amount of cash
Card readers and ATMs don't work without power
Copies of ID, insurance, and medical info
In a waterproof bag or folder, not just on your phone
Power is the item people get wrong most often
Flashlights and water are easy to remember. A dedicated power source usually isn't — most people only think about it mid-outage, when the fridge has already started warming up. A battery power station charged ahead of time (or topped off by a solar panel once the sun's out) covers a router, a CPAP overnight, phone and laptop charging, and a fridge or mini fridge for a stretch of the outage.
See the full runtime charts and kit comparison for exactly how long each battery size covers a fridge, CPAP, or router.
