What's behind our generator Ratings?

Experts at our National Testing and Research Center tested 14 models in generators to see which ones perform best.

We look for:

Overall score
Based on power delivery, power quality, run time, noise, and ease of use.
Ease of use
Includes starting, transport (for portables), and helpful features such as fuel shutoff.
Power delivery
How much wattage models delivered and how well they handled surges in power demand over various loads.
Noise
Measured at 23 and 50 feet from the generator. We recommend hearing protection for standing close by the unit while it's running.
Power quality
A generator's ability to deliver power smoothly, with consistent voltage.
Run time range
Our average of how long a generator ran, over various loads, on a full tank of gasoline or diesel fuel, a 20-pound tank for propane-based portables, or a 250-gallon propane tank for stationary models.

CR Best Buy: These blend performance and value. All are recommended.
Recommended: These high-scoring models stand out for their overall performance.

Generator buying guide

Blackouts needn't lead to spoiled food and nights by flashlight. Consumer Reports' generator tests show that you can start powering a houseful of lights and appliances for less than $700. But as we found, some important components cost extra.

We focused on moderately priced portable and stationary models that deliver 5,000 to 7,000 watts, enough for most needs. Portables cost the least and can be stored in a garage or shed when you don't need them. A lower-priced model powered refrigerators, well pumps, and other home gear almost as well as a more expensive top-scorer.

Stationary models install permanently outside your home and start automatically when needed. And because they run on propane or natural gas instead of gasoline, they offer extended or unlimited run time.

Buying a generator is just the beginning. Many models don't come with parts that you'd think would be part of the price. And some could let you down when you need them most or put an added load on appliances. Here are the details.
