How We Tested the Best Portable Generators

We carefully researched more than 35 portable generators before choosing seven highly rated models for hands-on testing. We looked at consumer satisfaction ratings, ease of use, value, and versatility. We also considered brand to an extent—Champion Power Equipment, Honda, and Westinghouse are all respected in the generator industry. However, we didn’t automatically eliminate smaller brands if their generators were quality built and highly rated. Our goal was to test models that would suit diverse user needs, so you’ll find powerful gas-fueled generators as well as dual-fuel and inverter models on our list. 

To test the generators, we assembled and fueled them according to each manufacturer’s instructions. We plugged in tools, appliances, and electronic devices according to an online wattage calculator to see if the generators would produce their advertised power. 

We tested the decibel level the generators produced when operating and noted how easy or challenging they were to move. Then we awarded points based on a rubric for how well each generator performed on specific tests and gave ratings for ease of use, noise, portability, power, and value.

For inexpensive off-grid electricity or an affordable home backup generator, the Ryobi offers one of the best watts-per-dollar values in our guide. Plus it comes equipped with numerous desirable features such as a dependable Ryobi engine, a rugged hand truck frame with 10-inch wheels and a fold-down handle, and a carbon monoxide sensor with automatic safety shutoff. The gas tank holds 6 gallons of fuel to keep the motor running for up to 10 hours on a 50 percent load. 

The Ryobi generator came mostly assembled, other than the wheels and handle. After adding oil and gas, we were pleasantly surprised when the engine started on the first pull, particularly since it doesn’t have an electric start option.

When it came to power production, the Ryobi let us easily run a couple of portable saws, a router, and work lights—plugged into the 120-volt 20-amp duplex outlets—for several hours without interruption. We also tried the 30-amp twist lock outlet with a three-way service cord to power the tools, and everything worked perfectly. 

While we appreciated that this heavy model has wheels, we still found maneuvering it awkward. We had to push the handle down to about a 45-degree angle and exert constant downward force while moving the 195-pound machine. But for its numerous features and ample power, the Ryobi is a great option.

When it comes to portable generators, 12,000 watts is near the top end, power-wise. The DuroMax XP12000EH is a dual-fuel monster that can power several tools and appliances simultaneously without throwing the breaker. 

We tested the DuroMax using gasoline and propane. It’s designed to run up to 8 hours on a full 8.3-gallon gas tank and up to 7 hours on propane at 50 percent capacity. It also has a couple of perks we really liked, including an electric starter—because who wants to hand-crank an engine when temps are bitter?—and a CO sensor that automatically shuts down the generator if it senses hazardous levels of carbon monoxide gas. 

The DuroMax has several plug-in ports, including a 120V-30A locking outlet, a 120/240V-30A locking outlet, two 120V-20A GFCI outlets (for standard power cords), and one 120/240V-50A outlet. We tested it by running our refrigerator, most of the entertainment devices in our home, and even a window AC that pulls a lot of juice. It didn’t lag at all.

Though we liked its power, the DuroMax missed the mark in a few areas. It doesn’t have drop-down covers to protect the outlets, and it only has two 120V standard outlets. Overall, though, we found this generator powerful and easy to use, particularly at this price point.

• Very easy to unpack and assemble; can begin using right away
• Delivers powerful wattage in a relatively compact size and has wheels for easy moving

Cons

•  Handle design is uncomfortable and awkward
• Wheels are plastic and might not hold up to long-term use on gravel surfaces

If you’re looking for a mid-range backup generator that won’t take up too much room in the garage, check out the Craftsman 6,000-watt portable generator. It features two 120V-30A and four 120V-20A outlets for plugging in various tools and appliances. 

This portable generator has an 8-gallon fuel tank and a recoil start. While many of today’s new generators come with electric starts, we found it easy to pull-start the Craftsman—and there’s less (electronically) to go wrong. This unit weighs 163 pounds, so you’ll need two or more strong people to lift it into and out of a truck or trailer. Its large wheels and handle make it easier to roll the generator once it’s on the ground, but the handle design is somewhat clunky and seems ill-suited for the generator. 

We tested the Craftsman by plugging in our refrigerator, an air compressor, a large space heater, a TV, and some corded power tools. The Craftsman surged and got a little louder when we ran the air compressor, but it still handled the load without flipping its breaker switch. 

While this 6,000-watt generator doesn’t run on propane, it’s a nice option for those who want reliable backup power or power on a remote jobsite.

The WGen9500DF is a portable dual-fuel generator that runs on gasoline and propane. It has a 457cc 4-stroke engine and features a 120/240V-50A outlet, a 120/240V-30A locking outlet, and four 120V-20A GFCI outlets. This is a heavy model, weighing in at 211 pounds, but it came mostly assembled—all we had to do was install the wheels and the handle.

We tested the generator using gasoline first, followed by propane, and got similar results for both. The generator features a 6.6-gallon gasoline tank that will keep it running for up to 12 hours at a 25 percent load. Actual tank runtime may vary depending on the quality of the gasoline and the electrical load you’re pulling. When connected to a 20-pound propane tank, the generator is designed to run up to 7 hours pulling a 50 percent load.

One of the nicest perks was the ability to start the generator from a distance using a remote control fob. We could start it while standing 90 feet away.

On both gas and propane, the generator ran several power tools simultaneously and powered an oven, range, and clothes dryer (at separate times) without throwing a breaker. This is an excellent pick for those who want an emergency generator that will power more than just a couple of cell phones or tablets.

• Carbon monoxide and low oil safety shutoffs protect the user and the equipment

Cons

• Powerful single-phase generator uses a lot of gas; not practical for low-draw applications

Portable electricity should be reliable, and you shouldn’t have to worry about whether the engine will start. The electric starter did the job even on a 12-degree Fahrenheit morning. It also has one of the smoothest recoil starters we tested.

This generator produces 8,000 running watts and up to 10,000 peak watts. It features an idle control button to conserve fuel and reduce noise during intermittent use. It delivers electricity through two 120-volt 20-amp duplex receptacles and a 120/240-volt 30-amp twist lock receptacle. 

The DeWalt generator delivered more than enough power for our “two saws and a router” shop test, so we plugged a refrigerator into the fourth outlet. The breakers did not trip, and all the equipment worked as intended. 

This portable generator is big and heavy (183 pounds without fuel) but balanced within its frame well. The fold-down handle and large wheels made it relatively easy to roll across the yard. Getting it in and out of the truck requires a team lift effort. The noise level was not too bad considering the output—similar to a gas lawn mower.

For those needing a lot of portable power, this generator fits the bill. Its wattage, outlets, and large 7.5-gallon fuel tank make it a smart general-use pick.

It’s equipped with an easy-to-use off/start/run selector knob and a smooth-pulling recoil starter. Best of all, this quiet model only produces between 48 and 57 decibels while in use. 

The compact size of the Honda EU2200i made it very easy to load and go. It weighs just over 47 pounds and has a well-designed top handle, so carrying it a few yards from the shed to the truck was no problem. Its 0.95-gallon tank provides up to 8.1 hours of runtime for a 25 percent load or 3.2 hours of continuous maximum output. We used eco throttle mode (which automatically adjusts power output to match the electrical load) to power a refrigerator for 4 hours, using about a half gallon of gas. 

The Honda’s 15A duplex receptacle operates like a three-prong electrical outlet, which allowed us to plug in our devices without worrying about overloading the circuit. It provides plenty of electrical service for basic home backups and can power up a portable table saw and miter saw simultaneously. Plus, it is parallel-ready (conversion kit sold separately), so users can run two together to double the output.

What to Consider When Choosing a Portable Generator

Choosing which portable generator to buy depends on how much power you need, which fuel type you prefer, and where you intend to take it.

Wattage 

Generators vary by the number of watts they are capable of producing. To find the right option, determine how many watts you will need. The answer depends on how you want to be able to use your generator. 

Make a list of must-have appliances and write down how many watts each one needs to start. Lighting typically requires 60 to 200 watts to start, a refrigerator needs about 600 watts, and a space heater or electric water heater may need as many as 1,500 watts. For many homeowners, a generator in the 5,000- to 7,000-watt range provides sufficient energy for power outages and large appliances.

Fuel Type

That list of must-have appliances also affects whether the best choice will be dual-fuel capable or will need to run on gas, propane, diesel, or solar power. 

• Dual-fuel generators do the same job as single-fuel generators. They run on propane or gasoline, allowing users to choose the fuel based on their needs, including power requirements, noise restrictions, and availability in the area. They have an isolated gasoline tank with a fuel capacity that ranges from as small as 2 gallons to more than 10 gallons. The larger the fuel tank on the generator, the longer the generator can provide gasoline-based power. For generators with smaller fuel tanks, users may want to consider keeping an extra gas can on hand. 
• Gas generators are very reliable options. As gasoline is a widely available fuel source, it is a common choice for portable generators. The primary disadvantages are that gasoline is more expensive and less efficient than other fuel sources, and gasoline engines typically emit the highest levels of carbon monoxide. Also, storing gasoline for long periods requires a fuel stabilizer, and if it’s stored incorrectly, gasoline can present a significant fire hazard.
• Diesel generators are also a reliable option. Although generators fueled by diesel aren’t as common as those fueled by gasoline, diesel is more affordable, more efficient, and can be stored for longer periods without a stabilizer. Diesel storage also doesn’t pose as significant a fire hazard as gasoline.
• Propane generators are clean burning and affordable. Propane generators may be tied into a home’s primary propane gas tank or have a designated tank strictly for the generator. The main disadvantages are that propane isn’t as energy efficient as other fuel sources, and a generator fueled by propane will usually have a shorter runtime and produce less power. Propane also presents a fire hazard if stored incorrectly.
• Solar generators are a great source of power for portable battery banks. As opposed to the energy used in gas generators, solar energy is silent, clean, and affordable. It’s also free. The disadvantages are that the power capacity is determined by the number and size of the panels and the size of the battery it charges. A solar panel’s ability to charge a battery is also dictated by the amount of available sun, so it isn’t as reliable a fuel source as other options. 

Inverter Generators 

Portable inverter generators produce electricity in three phases, first creating a high-frequency AC, which is then inverted to DC and then again to standard AC. Not only do portable inverter generators create more electricity, but this process also produces a very stable electrical flow, which is necessary for protecting delicate electronic systems such as those in computers and office equipment.

Weight

Portable generators can be heavy in order to supply power to small or large appliances, homes, power tools, and even RVs. A good rule of thumb with generators is that the larger the unit, the more power output it likely has. Many portable generators range in weight from 90 to 200 pounds, but they usually come with built-in handles and wheels to help with maneuvering and portability. 

Alternatively, some small portable generators weigh between 20 and 50 pounds, but these supply less power than larger generators. 

Noise Level

Portable gas-powered portable generators can be pretty loud. But some quiet generators are built with noise-absorbing glass wool, special mufflers, and vibration-absorbing feet. If users anticipate noise being an issue, the best generators to consider are ones specially designed to do their work effectively but quietly. 

A dual-fuel generator will produce 50 to 90 decibels of noise, depending on the size of the generator, the type of fuel (gasoline runs louder than propane), and the unit’s power output. Most generators fall between 65 and 75 decibels, which is comparable to the noise produced during normal conversation. 

To understand the range of sound produced by a generator, consider these common sounds and their equivalent operating decibel levels:

• Refrigerator: 40 decibels
• Hair dryer: 90 decibels
• Motorcycle: 100 decibels

The quietest dual-fuel generators belong to a relatively small group of products that utilize dual-fuel technology and inverter technology to create a dual-fuel inverter generator.

Accessories

While the above features are important aspects to consider before purchasing a portable generator, there are a few special features included in select models that add convenience and power. 

• Wheel kits are often sold separately, as are the transfer switches that enable users to wire the generator’s output to an electrical panel. Before you look for a generator deal, make sure to understand what, if any, components are going to be missing.
• Multiple outlets: Multiple outlets are convenient and help distribute the generator’s electrical load when powering multiple devices. A portable generator with at least two household electrical outlets is recommended for efficiently spreading the electrical load. Generators may also have RV outlets and USB ports.
• Line sharing: Purchasing a set of like-branded generators will often allow users to wire them in parallel, also known as load sharing. This means that by using a brand-specific kit, you can plug one generator into another to combine their wattages and produce even more power. Load sharing can also be a less expensive way to produce enough wattage to run large appliances or simultaneously power everything in an RV.
