A power generator is a fantastic nice-to-have item to keep around the house. After all, losing power in this day and age, even for a short time, can cause some headaches. Keeping a whole-house generator or portable power station ready to go can turn a night that may have been a genuine emergency into just a mild inconvenience. Outside of emergency use, they can also be used for camping, tailgating, and more. Portable generators and power stations can come in a wide range of prices with an even wider range of features, so although everyone has their own definition of the best portable generator, we’ve compiled this list of the best we could find according to user ratings and reviews. Check out our selection of the top power generators for 2023 below.

What is the difference between a generator and portable power station?
Usually, generators use some type of fuel such as gasoline or propane to “generate” their power from. Portable power stations on the other hand borrow their power from other electricity sources such as a wall or car charger.
How do you use a generator?
The most important thing to remember when using a traditional backup or portable generator is not to run it inside your home or garage, as it can give off dangerous carbon monoxide emissions. A portable power pack that has been charged up only using electricity is fine to run in the house. A standby generator is something larger and more complex that would require the input of an electrician to install and use.
How are generators powered?
The way a generator gets its power is unique to each individual device. You can find generators that are gas-powered, solar-powered, or even powered by propane. Ultimately, though, you’ll just have to check the requirements of the specific device you’re looking to buy.
How to hook up a generator to your house?
While some people do in fact take it into their own hands to install a whole-home generator, it can be a troublesome and sometimes risky process. We always recommend hiring or speaking to an electrician for the task.
What size generator do you need?
According to Consumer Reports, the most accurate way to determine what size generator you’ll need is to “consider the appliances you need to power and add up their wattage.” Home Depot provides a handy infographic showing approximate wattages of common household items you might want to keep running during an outage right here.
What size portable generator is best for a house?
This is highly dependent on how large your house is and how many appliances you’ll need to run, but a good formula for figuring out how many watts you’ll need out of your generator is to add up the running watts of all the appliances in your house you’ll want to run, then you’ll want to find your appliance that needs the highest starting watts and add only that number to your total. Whatever that total number is, you’ll need a generator that produces at least that amount of starting watts, and will also provide at least the same number of running watts as the sum total of the running watts of your appliances.
What size generator do I need to power a refrigerator, TV, lights, and a few appliances?
You can use the same formula as above to figure out what you need here, or reference this handy graphic from Home Depot.
What size generator do I need to run a refrigerator?
Again, this will be dependent on your refrigerator. Let’s say your refrigerator requires 600 running watts and 2,000 starting watts, in that case, you’d need a generator with at least 2,600 starting watts and at least 600 running watts.
Pros and cons of using a generator?
The benefits of using a generator or power pack are, of course, being able to keep your electronics charged and working during a power outage. Generators probably have more cons than smaller power packs due to their use of gas or propane to operate, but you may want to be cognizant of the electricity usage while charging a power pack as well.
How much does a whole-house generator cost?
Price can vary pretty significantly depending on how much power you’ll need and what features you’d like your generator to have, but to power your entire home you’re probably looking at around $800-$2,500.
Which portable generator is the best to buy?
Like so many things, there truly isn’t a “best” generator for every purpose. The portable generator that will best for you will depend on your needs and budget. For instance, if you’re just looking to make sure your phones and laptops stay charge, you’re probably in the market for something like a power pack, but if you need to make sure your refrigerator stays running, you’ll want to invest in something a little more heavy duty like a Champion or Duromax generator.
What is the best generator for residential use?
Again, while there isn’t a definitive “best,” if you’re worried about waking up your neighbors, we’d suggest looking for a generator that features a lower dB (decibel) level, or one that promotes “quiet operation” as a selling point, like this Champion Power Equipment 2000-Watt Dual Fuel Inverter Generator. The same goes for if you’re wondering what size generator is the best for camping.
