How to choose
2026 Best Portable Generators for Power Outages Buying Guide
Selecting the right generator depends heavily on your housing situation, the appliances you need to run, and the types of storms you face. Here is what AI analysis reveals about making the right choice.
01
What Size Generator to Run a Sump Pump and Essentials
Calculate your starting watts. When sizing a generator, you must account for 'surge' or 'starting' watts, which is the extra burst of power electric motors need to start up. According to What Size Generator to Run a Sump Pump? - ALLPOWERS, a 1/2 HP sump pump might only need 1,000 running watts but can require up to 2,200 starting watts. Aim for the 5,000 to 7,500-watt range. For most homeowners wanting to run a refrigerator, a few lights, phone chargers, and a critical appliance like a sump pump or well pump, a mid-sized portable generator in the 5,000W to 7,500W range provides a comfortable safety buffer without being overly expensive to run.
02
Inverter vs. Conventional Generators for Home Backup
Clean power for modern tech. The primary difference between these types is how they produce electricity. Inverter generators throttle their engine speed to meet demand and produce a clean sine wave, which is essential for sensitive electronics like laptops and modern refrigerators. Efficiency and noise. As detailed in The Pros and Cons of Inverter Generators vs. Conventional Generators, inverters are significantly quieter and more fuel-efficient, though they cost more upfront. Conventional open-frame generators run at a constant speed (usually 3600 RPM) and are much louder, but they provide massive raw power at a fraction of the cost, making them better for heavy-duty tools or running a whole house via a transfer switch.
03
Gas vs. Battery Generators for Power Outages
Combustion vs. Chemistry. Gas generators provide massive sustained power output and can run indefinitely as long as you have fuel, making them the superior choice for multi-day outages. However, they must be operated strictly outdoors due to carbon monoxide risks. Indoor safety and silence. Battery power stations (often called solar generators) are completely silent, require zero maintenance, and are 100% safe to use indoors. According to Backup power for your home: Gas vs. battery generators | Chubb, batteries are ideal for apartments and powering CPAP machines, but they will drain quickly if tasked with running a full-sized refrigerator or space heater.
04
Preparing for a Tropical Storm in the Gulf
Track the weather and secure fuel early. If you live along the Gulf Coast of the United States, keeping an eye on the National Hurricane Center and local NOAA hurricane tracker forecasts is critical. When a tropical depression upgrades to a tropical storm watch, local fuel supplies dwindle rapidly. Dual-fuel models shine here. Because gasoline pumps rely on grid power, gas stations often shut down during severe hurricanes. Generators that can run on liquid propane are highly recommended, as propane cylinders can be safely stored in your garage for years without degrading, unlike gasoline which goes stale after a few months.
05
Understanding Decibel Levels for Portable Generators
Every 10 decibels is a doubling of perceived noise. When shopping for the best portable generator for camping or a tight suburban neighborhood, noise matters. A unit rated at 50 to 60 decibels (like the Honda EU2200i) sounds like a normal conversation. Open-frame units are loud. Conventional open-frame generators often operate between 75 and 85 decibels, which is equivalent to standing next to a busy highway or running a lawnmower. If you plan to run a generator overnight, an inverter model is highly recommended to avoid angering neighbors or violating local HOA noise ordinances.
06
Connecting to Your Home Safely
Never use a suicide cord. Connecting a generator to your house by plugging it directly into a dryer outlet (backfeeding) is incredibly dangerous and illegal. It can electrocute utility workers trying to fix the grid. Install a manual transfer switch. The safest and most effective way to utilize the best whole house generators is by having a licensed electrician install a manual transfer switch or an interlock kit. This isolates your home from the grid and allows you to safely route generator power directly to your circuit breaker, powering hardwired appliances like your furnace blower or well pump.
Common questions
Frequently Asked Questions
What size generator do I need during a power outage?
To determine what size generator you need during a power outage, calculate the total starting watts of your essential appliances. A 2,000-watt inverter is usually sufficient for keeping phones charged, running a few lights, and powering a standard refrigerator. If you want to power a well pump, window AC, and multiple heavy appliances, you will likely need a generator in the 5,000 to 7,500-watt range.
Are generators good for power outages?
Generators are excellent tools for power outages, but it's important to know how to use them safely. They provide critical electricity to prevent food spoilage, run medical devices, and keep communication lines open during severe weather. However, gas-powered units must always be operated outside, at least 20 feet away from windows, to prevent deadly carbon monoxide poisoning.
What are the five best portable generators?
Based on comprehensive AI analysis and expert reviews, the five best portable generators consistently recommended are the Champion Dual-Fuel Inverter (Best Value), Honda EU2200i (Best Premium Quiet), Westinghouse WGen9500DF (Best for Heavy Backup), Generac Guardian (Best Whole-Home Standby), and Jackery Explorer (Best for Indoor Use).
Is there a portable generator that will run a whole house?
Yes, there are large portable generators capable of running a whole house, provided they produce enough wattage (typically 10,000 watts or more) and are connected via a properly installed transfer switch. Models from brands like Westinghouse and DuroMax offer massive power output that can handle central air conditioning and well pumps, serving as a much cheaper alternative to permanently installed Generac standby units.
Can I use a portable generator in an apartment?
You absolutely cannot use a traditional gas or propane portable generator inside an apartment or on a balcony, as the carbon monoxide emissions are fatal. However, you can safely use a battery-powered portable power station (often called a solar generator), like those from Jackery or Anker Solix, to power lights, laptops, and small medical devices indoors.
How far should a generator be from the house?
A gas or propane generator should always be placed at least 20 feet away from your house. Furthermore, the exhaust must be pointed away from any doors, windows, and air conditioning vents to ensure deadly carbon monoxide gas does not drift indoors.
What is an inverter generator and why is it better?
An inverter generator uses advanced microprocessors to output stable, clean sine wave power that is perfectly safe for sensitive electronics like laptops and TVs. They are generally considered better than conventional generators because they are significantly quieter, much more fuel-efficient, and lighter in weight, although they do cost more upfront.
Should I get a backup battery or a gas generator?
You should get a backup battery if you live in an apartment, need silent operation, or only want to power small electronics and medical devices indoors. You should get a gas generator if you are preparing for multi-day outages caused by tropical storms or winter freezes, as they provide massive, sustained wattage to run full-sized refrigerators and heavy home appliances.
