“A home standby generator does a great job of supplying backup power during an outage,” says Dave Trezza, the test engineer who heads CR’s generator testing program. “But standby generators aren’t cheap, and the installation can be complex and expensive—not a DIY job. That’s why you need a properly sized, top-performing model from our tests that delivers steady, reliable power.”
The largest models we test deliver at least 10,000 watts of electricity, enough to power everything in an average home. Smaller models provide at least 5,000 watts, enough to power many key household appliances, electronics, and systems in your home. They will, for example, keep your refrigerator, air conditioner, and well pump running.
