If a generator performs its primary function well, you'll need to look at features and conveniences to compare models. That's a particular strength of recreational inverter generators, as you can see in the models below: They offer niceties such as extra receptacles for gadgets and remote control from a smartphone app. Most of them also serve a purpose beyond the tailgate.

More on Generators

"Recreational inverter generators are really designed to be a portable power source, but in a pinch, you can actually use them to power a few appliances at home," says Dave Trezza, who heads up Consumer Reports' generator testing.

All the recreational inverter generators in CR's ratings max out at 2,000 or fewer watts and weigh about 50 pounds. The portable generators we test range from 4,500 to 7,500 watts and weigh up to 200 pounds. If you're not sure what's right for you, check our generator buying guide.

As for the three recreational inverter generators below, they all perform well in our tests and deserve a shout-out for designs that are clearly conceived with the user in mind.

New Portable Generator Safety Features

To reduce the risk of carbon monoxide poisoning, some new generators feature a built-in sensor that triggers an automatic shutoff if CO builds up to dangerous levels in an enclosed space, and some also have engines that emit less CO in the first place. Recent test data from CR shows that these safety features are likely to save lives.

Consumer Reports recommends portable generators only if they pass our new CO safety technology test. None of these recreational models feature either a CO safety shutoff or a low-CO engine.

As with all generators, these should be used outdoors only, 20 feet from the house, with the exhaust directed away from windows and doors.

CR's take: This Ryobi generator was definitely designed with usability in mind. For starters, it has wheels and a telescoping handle, like a luggage wheelie, making it easy to move around or take with you on a trip (not via air travel, of course). But its real innovation is the built-in software called GenControl, which partners with an app and uses Bluetooth to send critical information to your smartphone, including current output wattage, fuel level, and remaining run time. That means you can simply check your phone instead of continually running out to check the gas gauge to see when you'll need to refill the tank. You can even use your phone to shut it off. It's also a strong performer, earning a rating of Excellent for power quality.

CR's take: This lean little generator from Briggs & Stratton is the only recreational model we've seen with receptacles for standard plugs, a USB port, and a 12-volt, cigarette lighter-style outlet. That means that you can plug in almost anything you'd need to plug in during an emergency, or if you have a lot of phones to charge, use a dual USB charger in the 12-volt port without tying up all the standard outlets. Alternatively, you can charge up to five phones at once if you aren't using the standard outlets to power anything inside your home. It's a good performer, with a rating of Excellent for power quality.

CR's take: This Champion inverter generator allows you to stack up to four units on top of one another, and connect the units with a cord to output capacity as high as 6,800 watts. At this price, it's probably still cheaper to stack multiple units than to buy a single, larger generator. But it's also great as a standalone generator, earning a rating of Very Good for power delivery.
