When a storm knocks out power for days, a generator can keep your refrigerator cold, your lights on and your phones charged. Inverter generators make clean, stable power that is safe for electronics, run much more quietly than traditional generators, and use less fuel. The best inverter generator for home backup has enough watts for your essentials, runs through the night on a tank, and has a built-in carbon monoxide safety shutoff.
We compared the most popular inverter generators on running and starting watts, noise, fuel type and run time, weight, carbon monoxide safety features and price. Here are our picks for 2026.

How to choose an inverter generator
1. Add up the watts you need
List what you want to run and add up their running watts. Then make sure the generator’s starting watts can handle the brief surge when a fridge or pump motor starts. A typical refrigerator needs about 700 running watts and more to start.
2. Choose a carbon monoxide shutoff
Look for a built-in CO sensor that shuts the generator off if carbon monoxide builds up. Many new models have one, and the CPSC strongly encourages it.
3. Consider dual fuel
Propane does not go stale and is often easier to find after a storm. Gasoline goes stale in a few months unless you add stabilizer.
4. Check run time and tank size
A generator that runs through the night on one tank means fewer trips outside in bad weather.
5. Plan how to connect it
Use heavy-duty outdoor extension cords, or have an electrician install a transfer switch or interlock. Never plug a generator into a wall outlet, which can backfeed power and endanger utility workers.
Generator safety: avoid carbon monoxide poisoning
Portable generators cause many carbon monoxide deaths every year. You cannot see or smell CO, and it can kill in minutes. The CPSC and Ready.gov recommend:
- Only run a generator outdoors, at least 20 feet from your home, with the exhaust pointed away from doors, windows and vents.
- Never run a generator inside a home, garage, basement, shed or crawl space, even with the doors open.
- Install battery-powered or battery-backup CO alarms on every level of your home.
- Let the generator cool before refueling, and store fuel safely away from the house.
- Keep it dry and protected from rain with a cover designed for running generators.
Frequently asked questions
What size generator do I need for my house?
For a fridge, lights, phone chargers and a fan, about 2,000 to 2,500 starting watts is usually enough. To add a sump pump, freezer or window AC, look at 3,500 watts or more. Whole-home backup needs a much larger standby generator.
What is the difference between an inverter generator and a regular generator?
Inverter generators produce cleaner, more stable power that is safe for electronics, run more quietly and use less fuel. Conventional generators offer more watts for the money but are louder.
Can an inverter generator run a refrigerator?
Yes. Most 2,000-watt inverter generators can run a standard refrigerator, as long as you do not add too many other loads at once.
How far should a generator be from my house?
At least 20 feet, with the exhaust pointing away from the home, according to the CPSC.
Can I run a generator in the rain?
Only with a cover made for running generators, or under an open canopy that keeps it dry and well ventilated. Never run it in a garage to keep it dry.
Is a portable power station a better choice?
Battery power stations are silent and safe indoors, but they store limited energy. A generator can run for days on fuel. Many families use both.
The bottom line
For most homes, the Honda EU2200i is the best inverter generator for home backup, thanks to quiet running, a CO shutoff and the option to pair two units. Choose the Champion 2500-Watt Dual Fuel for propane flexibility, the Westinghouse iGen5000c for more power, or the WEN DF280iX on a budget.
