Reviewed byEthanWhen choosing a best size generators for home backup, the single most important spec is running watts. This number tells you how much continuous power the generator can deliver to run your essential appliances during an outage. Brand loyalty or a low price tag won’t keep your refrigerator cold or your lights on if the generator can’t handle the load. We’ve compared 5 models based on this critical metric, along with fuel efficiency, noise levels, and portability, to help you find the right fit for your home. For more on whole-home solutions, see our guide on The 5 Best Home Generators Options For Backup Power of 2026.
Running Watts Explained
Running watts, also called rated watts, is the amount of power a generator can produce continuously over several hours. Starting watts (or surge watts) are higher but last only a few seconds to start motors in appliances like refrigerators or well pumps. For home backup, you need a generator whose running watts exceed the total wattage of the devices you plan to run simultaneously.
To make this practical, let’s look at the Westinghouse iGen2800. It delivers 2,200 running watts. A typical refrigerator uses about 700 watts, a few LED lights around 100 watts, and a sump pump around 800 watts. Add them up: 700 + 100 + 800 = 1,600 watts. That leaves 600 watts of headroom, meaning the iGen2800 can comfortably power these essentials without being overloaded. This calculation shows why knowing running watts is key to sizing your generator correctly.

Fuel Efficiency and Runtime
During a prolonged outage, how long your generator runs on a tank of fuel matters. The Westinghouse iGen2800 offers up to 12 hours on 0.98 gallons, while the WEN models provide 12.5 hours on 4.3 gallons. Inverter generators like the Honda and Westinghouse are generally more fuel-efficient because they adjust engine speed to the load. For more on inverter technology, see our guide on The 5 Best Generators For Camping And Home of 2026.
Portability and Weight
If you need to move your generator from storage to the backyard or take it camping, weight is crucial. The PowerSmart 1200W weighs only 39 pounds, making it the lightest option. The Westinghouse iGen2800 at 46.3 pounds is still manageable, while the WEN models with wheel kits are easier to roll than carry. For RV use, check out The 5 Best Generators For Rv Living of 2026.
Noise Level
Inverter generators like the Honda and Westinghouse operate at around 52 dBA, which is quieter than a normal conversation. Conventional generators like the WEN models are louder, often in the 60-70 dBA range. If noise is a concern for neighbors or sleeping family, an inverter model is the better choice.

Frequently Asked Questions
How do I calculate the running watts I need for home backup?
Add up the running watts of all appliances you want to power simultaneously. For example, a refrigerator (700W), a few lights (100W), and a sump pump (800W) total 1,600 watts. Choose a generator with running watts at least 20% higher than that total to avoid overloading.
Can I use a portable generator indoors?
Never. Generators produce carbon monoxide, a deadly gas. Always operate them outdoors at least 20 feet from windows, doors, and vents. Models with CO sensors, like the WEN GN5602X, add an extra layer of safety but do not replace proper placement.
What is the difference between an inverter generator and a conventional generator?
Inverter generators produce cleaner power (less than 3% total harmonic distortion) that is safe for sensitive electronics like laptops and smartphones. They are also quieter and more fuel-efficient. Conventional generators are generally cheaper and offer higher wattage but are louder and produce less stable power. For more on this topic, see our guide on The 5 Best Home Backup Solar Generators of 2026.
How often should I run my generator to keep it in good condition?
Run your generator for 30 minutes under load every month to keep the engine lubricated and prevent fuel system issues. Use a fuel stabilizer if storing for more than 30 days.
