Power Outages Are the Most Common Hurricane Disaster — Plan for Weeks, Not Days

After a major hurricane, power outages in affected areas commonly last 1 to 4 weeks. After Hurricane Maria in Puerto Rico, some areas waited over a year. After Milton and Helene in 2024, hundreds of thousands of Florida and Appalachian residents were without power for 7 to 14 days. A generator is no longer a luxury for coastal residents — it's essential hurricane infrastructure.

How Much Power Do You Actually Need?

Calculate your minimum wattage needs by listing the appliances you must run. Note that starting wattage is typically 2–3x the running wattage for motor-driven appliances like refrigerators and AC units.

ApplianceRunning WattsStarting Watts
Refrigerator/Freezer150–400W1,200W
Window AC (10,000 BTU)1,200W2,200W
Central AC (2.5 ton)3,500W7,500W
Sump Pump800W2,000W
CPAP Machine30–60W
Phone/Laptop Charging50–250W
LED Lights (per fixture)8–20W

Add up your essential appliances and purchase a generator with 20–25% more capacity than your total to avoid overloading.

Critical Safety Rules — Non-Negotiable

Carbon monoxide from generators kills dozens of Americans every year, most in the days following hurricanes. CO is odorless, colorless, and lethal within minutes at high concentrations.

Never run a generator inside a garage — even with the door open. Never run one on a covered porch or within 20 feet of any window or door. Install a CO detector on every floor of your home. Never backfeed power through an extension cord — use a transfer switch installed by a licensed electrician. Run and test your generator every 30 days year-round.

Buy your generator in April or May before the season. Generator shelves empty within hours of a storm being named. Use our Prep Checklist Builder to plan your full household preparedness. Sign up for storm alerts to know when to activate your generator plan.
