Backup power is only one part of outage prep. Food, water, communication, medication, lighting, and temperature safety often matter more than another battery purchase.
Food plan
Ready.gov, CDC, and FDA all emphasize the same basic habits:
- keep refrigerator and freezer doors closed
- use appliance thermometers
- know what must be discarded
- use coolers and ice when appropriate
- when in doubt, throw it out
Ready.gov and CDC give a common planning rule: a closed refrigerator keeps food cold for about 4 hours, and a full freezer can hold temperature much longer if unopened. Use thermometers and official guidance rather than smell or optimism.
Water plan
Store water before storms when possible. If your water depends on a pump, electricity matters. If local officials issue boil water or safety instructions, follow those instructions.
Communication plan
Have:
- charged phones
- battery bank
- car charger
- printed emergency contacts
- battery or hand-crank radio
- local alert method
- plan for power-dependent internet failure

Medical and medication planning
If you use refrigerated medicine or power-dependent medical equipment, make a plan before the outage with your medical provider, device provider, or pharmacist. Do not rely on a generic battery estimate for critical care.
Link the kit to the power plan
Once the non-gadget plan is clear, backup sizing gets easier. A refrigerator thermometer, radio, lantern, and phone charging plan may reduce the pressure to run the entire house.
