When the lights come back on, the job is not finished. Surges, spoiled food and drained batteries are the usual problems. Work through this checklist in order.
✅ The Checklist
- Turn off or unplug big appliances you were using when the power failed. The Red Cross warns that surges or spikes when power returns can damage equipment.
- Leave one light on so you know when power is stable.
- Wait a few minutes, then reconnect appliances one at a time, starting with the fridge and freezer. This avoids a pile-up of startup loads.
- Check the food. Perishables should be at 40°F (4°C) or below. The USDA says a closed refrigerator keeps food safe about 4 hours, a full freezer about 48 hours and a half-full freezer about 24 hours. Use a thermometer, and when in doubt, throw it out. See our food-safety timeline.
- Recharge your backup power right away. Plug your power station into the wall so it is ready for the next outage. Many units recharge to near full in one to two hours from a wall outlet, depending on the model.
- Reset what tripped. Check breakers, reset clocks and thermostats, and check the sump pump and any other motors.
- Stay away from downed lines and report them to the utility.
🔌 Generators and Carbon Monoxide
If you used a fuel-burning generator, the CDC says to never run it inside your home or garage, and to keep it more than 20 feet from windows, doors and vents. Battery-powered CO alarms near sleeping areas protect you if anything goes wrong. A battery power station produces no exhaust, but it still needs a recharge.
Quick picks
EcoFlow DELTA 3 Plus (1,024Wh, about 56 minutes from the wall): quick recharge between outages. Check the current listing on EcoFlow's site.
Bluetti Elite 200 V2 (2,073.6Wh, 2,600W): longest runtime of the three in this guide. Check Bluetti Elite 200 V2 Price
