Westinghouse 12500 Watt Dual Fuel Home Backup Portable Generator, Remote Electric Start, Transfer Switch Ready, Gas and Propane Powered
The 2026 hurricane season and a summer of severe thunderstorms and flash floods mean one thing for millions of households: the grid will go down when you need it most. This guide breaks down the best generators for storm and flood power outages so you can keep the lights, fridge, and medical devices running safely.
Why the Right Generator Matters for the 2026 Hurricane Season
Outages during hurricanes and flash floods are rarely brief. When crews cannot reach downed lines, power can stay off for days. A generator sized and fueled correctly protects your refrigerator, sump pump, medical equipment, phones, and internet, turning a dangerous situation into a manageable one. But choosing the wrong unit can leave you underpowered, out of fuel, or exposed to deadly carbon monoxide (CO). Below we cover the three main generator classes, wattage sizing, fuel choices, and the safety rules that keep families alive during severe weather.
Before you shop, jump to the section you need: generator types, wattage sizing, fuel types, CO safety, or the storm-ready shopping list.
Portable vs. Inverter vs. Standby Generators for Power Outages
The first decision is the generator class. Each one solves the outage problem differently, and the best storm generator for you depends on budget, how long outages last in your area, and whether you can install permanent equipment.
Portable Generators for Storm Power Outages
Conventional portable generators deliver the most watts per dollar. A mid-size 5,000-8,000 running-watt unit can power a fridge, a window AC, lights, and a sump pump at once. They are loud and produce “dirty” power that can harm sensitive electronics, but for flood recovery, running pumps, and hardwiring essentials through a transfer switch, they are the workhorse choice.
Inverter Generators for Sensitive Electronics
Inverter generators produce clean, stable power (low total harmonic distortion) that is safe for laptops, routers, phones, and medical devices. They throttle the engine to match load, so they are quieter and far more fuel-efficient. Many are parallel-capable, letting you link two units for more capacity. They cost more per watt but are ideal for extended outages where fuel is scarce.
Standby Generators for Whole-Home Backup
Standby (home standby) generators are permanently installed, run on natural gas or propane, and start automatically within seconds of an outage via an automatic transfer switch. They are the gold standard for hurricane-prone regions because they can power an entire home for days without refueling. The trade-off is cost and professional installation, but for households that lose power every season, the convenience and safety are unmatched.
Generator Comparison Table: Best Options by Situation
| Generator Type | Strength | Best For |
|---|---|---|
| Portable Generator | Most watts per dollar; runs pumps, fridge, and AC | Flood recovery and hardwired essentials via transfer switch |
| Inverter Generator | Clean, quiet, fuel-efficient power | Sensitive electronics and long outages with limited fuel |
| Home Standby Generator | Automatic whole-home backup for days | Hurricane-prone homes with frequent, multi-day outages |
| Portable Power Station | Zero emissions; safe indoors; solar-rechargeable | Apartments, CPAP machines, and indoor phone/medical charging |
| Dual-Fuel Generator | Runs on gasoline or propane for fuel flexibility | Long storms when one fuel type runs out |
How to Size Generator Wattage for Storm Outages
Correct wattage sizing is the single most common mistake. Add up the running watts of everything you want to power at once, then make sure your generator’s running-watt rating exceeds that total with headroom to spare. Also account for starting (surge) watts: motors in refrigerators, sump pumps, well pumps, and air conditioners briefly draw two to three times their running wattage when they kick on.
Typical Wattage Needs During an Outage
- Refrigerator/freezer: 600-800 running watts, ~1,200-2,000 starting watts
- Sump pump: 800-1,050 running watts, up to 2,150 starting watts
- Window AC (10,000 BTU): ~1,200 running watts
- Lights and phone charging: 200-400 watts
- Furnace blower: 600-800 running watts
- Well pump (1/2 HP): 1,000 running watts, ~2,100 starting watts
For essentials only, a 3,500-4,500 running-watt unit is often enough. To run a sump pump plus fridge plus a window AC and lights simultaneously during a flood, plan for 6,000-8,000 running watts. Whole-home comfort with central AC usually requires a 12,000+ watt portable or a standby unit. When in doubt, size up: a lightly loaded generator runs cooler, quieter, and longer.
Fuel Types: Gasoline, Propane, and Dual-Fuel
Fuel strategy makes or breaks a storm plan. Gasoline is widely available but degrades in months, and stations cannot pump it when the grid is down, so stockpiling before a storm is essential. Propane stores indefinitely, burns cleaner, and is easy to keep on hand in tanks. Natural gas (standby units) offers unlimited runtime as long as the utility line is intact. Dual-fuel generators give you the best of both worlds, letting you switch to propane when gas stations run dry. Always store fuel outdoors, away from living spaces, and add stabilizer to any gasoline you keep for emergencies.
Carbon Monoxide (CO) Safety: Never Skip This
Carbon monoxide from generators kills people every hurricane season. CO is invisible and odorless, and running a generator in a garage, porch, or near an open window can be fatal within minutes. Follow these non-negotiable rules:
- Run generators outdoors only, at least 20 feet from doors, windows, and vents, with the exhaust pointed away from the house.
- Never run a fuel-burning generator indoors or in any enclosed or partially enclosed space, even with ventilation.
- Choose a model with a built-in CO shutoff sensor that automatically kills the engine when CO builds up.
- Install battery-powered CO detectors on every level of your home and test them before storm season.
- Keep the unit dry. Use a running cover or canopy rated for generators; never operate on flooded ground or in standing water.
For indoor charging of phones and CPAP machines, a battery-powered portable power station produces zero emissions and is safe to use inside, making it the smartest companion to any fuel generator.
Storm-Ready Shopping List
Build your outage kit around these essentials. Prices change, so check current listings before you buy:
- Portable generator (7,000-8,000W dual-fuel) for pumps, fridge, and hardwired essentials.
- Inverter generator for clean, quiet power to sensitive electronics.
- Portable power station for safe indoor phone, laptop, and CPAP charging.
- Transfer switch to safely power hardwired circuits like your furnace and well pump.
- Heavy-duty extension cords rated for outdoor generator use.
- Battery-powered CO detector for every level of your home.
Frequently Asked Questions
What size generator do I need for a house during a hurricane?
For essentials like a fridge, sump pump, lights, and phone charging, a 5,000-8,000 running-watt generator is usually enough. To run central air conditioning or power the whole home, you will need a 12,000+ watt portable or a home standby unit. Always add starting-watt headroom for motor-driven appliances.
Can I run a generator during a flood or heavy rain?
Never operate a generator in standing water or on flooded ground, and never run it indoors. Keep it on dry, elevated ground and use a generator-rated running cover or canopy to shield it from rain while allowing exhaust to vent safely away from your home.
Is a portable power station enough for a power outage?
A portable power station is perfect for charging phones, laptops, CPAP machines, and running small devices safely indoors with zero emissions. However, most cannot power high-draw appliances like a sump pump or window AC for long, so pair one with a fuel generator for extended storm outages.
How do I keep a generator running safely for days?
Stockpile fuel before the storm (gasoline with stabilizer or propane tanks), size the unit so it is not overloaded, and let it cool before refueling. Use a model with a CO shutoff sensor, keep it at least 20 feet from the house, and rotate it off periodically per the manufacturer’s maintenance schedule.
