Define critical loads
List what truly needs electricity: phone charging, medical equipment, refrigeration, lights, fans or heat controls. Add wattage and expected runtime before shopping.
Understand the options
Battery power stations are quiet and can be used indoors when operated as designed; fuel generators can provide substantial output but create carbon monoxide and fuel-storage risks and must be operated outdoors.
Plan for runtime
A power source is only useful for as long as its stored energy or fuel lasts. Prioritize loads rather than assuming you can run the whole house.
What to do next
Turn this topic into one or two concrete household actions. Preparedness works better as a maintained system than as a one-time shopping list.
