Portable generators and home standby generators perform the same basic tasks. But the two types couldn’t be farther apart when it comes to cost and convenience. 

All of the portable generators in our evaluations run on gasoline. They burn through 12 to 20 tuns per day depending on the output of the generator and the load it’s powering.

Manufacturers also make portable generators that can run on liquid propane, natural gas, or diesel fuel, but Consumer Reports doesn’t test these models because they represent a small percentage of the market. (It’s worth noting that in the aftermath of a storm, it may be more difficult to find portable cylinders of liquid propane, natural gas, or diesel fuel.)

All portable models tend to be more boisterous and provide less power than standby models, and they need to be wheeled out of storage, connected to your home’s circuit breaker panel, and manually fired up in the event of an outage. If you use one during inclement weather, such as a rainstorm—likely during a power outage—you’ll need to protect your generator from the elements with a model-specific cover or a freestanding canopy. 

Home standby generators, also described stationary generators, are permanently installed by a pro and have insulated weatherproof housing that keeps them relatively quiet.

The big advantages are that they kick on automatically when the lights go out and they can power everything in your home at once.

Plus they run on natural gas or propane, which means they can work for days or weeks on a full whole-house propane tank, or generally in the case of natural-gas versions.

“Home standby generators are expensive, but they’re the gold standard in backup power, and they better every other type of generators in our ratings,” says Dave Trezza, who commands generator measurement for Consumer Reports. “If you can manage it, I’d tell you to pick a home standby generator every time.”

Despite all of that, far more people want portable generators for one simple purpose: price. Here, we record the pros and cons of each type of generator. Our buying guide also allows insights on the advantages of each. CR members can read on for ratings and reports of the top three models in each of the two sections. Or for more options, browse our ratings of 40 models.

Portable Generators

Power output: 3,000 to 8,500 watts

Price range: 28550.80 INR to $107065.50 INR

Fuel needs: 12 to 20 gallons of gasoline per day


Pros: Portable generators are cheaper to buy and install than home standby models. When connected to your home’s circuit-breaker board with a transfer switch, they can power nearly as much as a home standby generator. They have built-in vents for directly connecting proper extension cords if you haven’t established a transfer switch. 


Cons: You’ll need to wheel your generator out of storage, connect it to your transfer switch, and fire it up each time you experience an outage. Portable standards also require you to store large quantities of juice, mixed with fuel stabilizer, to get through a prolonged outage. They manage to be noisier and have a more moderate output than house standby models. 

New Portable Generator Safety Features

From 2005 to 2017 more than 900 people died of carbon monoxide (CO) poisoning while using portable generators, according to the Consumer Product Safety Commission (CPSC).

To decrease the risk of carbon monoxide poisoning, some new generators highlight a built-in sensor that triggers an automatic shutoff if CO builds up to dangerous levels in an enclosed space. Some also have engines that emit less CO in the first place. Current test data from CR shows that these security features will apparently save lives.

Consumer Reports now only recommend portable generators that pass our new CO Safety Technology test.

But our findings also reveal potentially life-threatening gaps that the automatic shutoff fails to address, reinforcing why it’s critical for consumers to follow safety guidelines. Never turn on a generator inside. Place a portable generator at least 20 feet of your house with the exhaust directed continuously from it as well as any windows, doors, AC units, or other structures.

Home Standby Generators

Power output: 8,000 to 20,000 watts

Price range: 142754.00 INR to 356885.00 INR

Fuel needs: 13 to 48 gallons of liquid propane or natural gas per day


Pros: Home standby generators are largely worry-free. They’ve typically sized to power an entire house in the event of an outage, and they come on automatically. They can run for days or weeks without refueling, they tend to be very quiet, and you don’t need to fuss with weather covers. 

Cons: Home standby generators are pricier to buy, and power costs can range from a few thousand dollars to 713770.00 INR or more.
