Portable power station for a multi-day power outage
Once it's clear an outage will run days, shift into conservation mode.

The first hour of an outage and the first morning you realize it's not ending soon call for different responses. Here's the priority order once it's clear you're in for a multi-day event.

First: protect what spoils fastest

Keep the fridge and freezer closed as much as possible — a full freezer holds temperature for about 48 hours unopened, a fridge closer to 4 hours. See our food safety timing guide for exact thresholds before you start deciding what to eat first versus what to toss.

Second: shift into power conservation mode

If you have a power station or generator, prioritize the fridge, medical equipment and communication devices over convenience items — a multi-day outage means rationing capacity, not running everything as usual. Charge phones and devices during daylight if you're supplementing with solar.

Third: manage information and communication

  • Keep a battery or hand-crank radio for emergency broadcasts if cell towers are affected
  • Conserve phone battery for essential calls and check-ins rather than constant scrolling
  • Check on neighbors, especially elderly or medically dependent ones, once it's safe to do so

Fourth: manage temperature

In winter, close off unused rooms and layer up before burning through generator fuel or power station capacity on space heating; in summer, stay hydrated and use battery-powered fans over AC where possible. See our winter storm guide for the cold-specific version of this.
