Portable Generators Made in the USA (And Our Top Picks)

We did the research to find the best portable generators made in the USA. Different people have different needs when it comes to purchasing a generator: backup power supply, camping, power tools, and many others. Below, you’ll find recommendations for several of those use categories, as well as detailed product information about each, and even our research methodology.

Our Findings

Overall, we found it really difficult to find generator companies that are sourcing 100% of their materials from U.S. manufacturers. However, we did find four companies that are sourcing a lot of their materials here and are of course employing great American workforces to make high quality generators: Dayton, MI-T-M, NorthStar, and Winco. Each of them build great generators whether you need it for work or home. You can find NorthStar generators at Northern Tool and Winco generators on their site, wincogen.com. Both of these options are good for commercial uses on the job site. Dayton and MI-T-M, which we’ve detailed more below, have better options for home. We previously had Champion and Generac generators here as well, but unfortunately they moved a lot of their manufacturing overseas.

Top Recommendations

Recommendations: Going Deeper

Below, we go into a ton of detail about each of our top picks, why we liked them, and some pros and cons for each.

Best Heavy Duty Portable Generator

MI-T-M Portable Generator

MI-T-M makes some great generators for heavy duty jobs. It’s perfect for powering: large appliances during your next power outage, multiple power tools, large AC units, and other heavy duty jobs. It has a brushed 120V/240V alternator and a THD (total harmonic distortion) of under 5%. The run time for the 4,400W model (pictured here) is about 11 hours on a full tank of gas at 50% power and roughly 6.5 hours at full load, which is pretty standard for generators around this wattage. The durable steel frame was the sturdiest among the models we looked at. If you need a heavy duty generator for the job site or for emergencies around the house, this is a good option. The only major downside is the engine, which can vary depending on where you shop. MI-T-M uses everyone from Kohler to Subaru for their engines, but we found it extremely tough to find portable generators that didn’t source their engines from other companies that potentially produce them overseas. Otherwise, this reliable generator is made here.

  • Easy to transport
  • Easy access to all maintenance areas
  • Impact resistant fuel tank and steel frame
  • Good idle control
  • Strong run time

Things we don’t like:

  • Engine manufacturer can vary

Best High Wattage Portable Generator

Dayton Portable Generator

If you need a ton of power in your generator, Dayton makes some great high wattage models. The one we really like is the 6,500W model, mainly because of its versatility. For unexpected power outages, this portable generator has enough power to run your large appliances, security system, sump pump, lights, and other small appliances throughout the house. It’s also great for use on a job site or campground that requires a lot of power. A sturdy steel tube exterior prevents damage to the engine inside. The engine and oil filter are constructed nicely on this generator for longer engine life, and it has some nice safeguards on it too, like a low oil automatic shutdown to prevent engine damage and a maintenance alert system. The only downside is similar to MI-T-M generators – the engine manufacturer inside the generator can vary.

Things we like:

  • Durable steel frame
  • Safeguards for engine protection
  • Electric start
  • Brushless engine alternator
  • 7.3 gallon fuel tank – runs for 11 hours at 50% load
  • Run time hour meter

Things we don’t like:

  • Engine manufacturer can vary, sometimes use Honda

Recap: Best Portable Generators Made in the USA

Factors We Considered


Portable generators are a lifetime investment. If you buy the right one and take care of it, they can last you decades of use. We looked for generators that showed durability in their frame, engine construction, and much more to make sure that the generator you end up choosing is an asset to you in times of need.

Power Level

Portable generators have several different use cases, everything from rebooting large appliances when your power goes out, to firing up the TV at your next tailgate or running the pressure washer at your job site. Each of these tasks and many others require different power levels. The more available wattage you have in your portable generator, the higher load tasks it can handle. Typically, anything above a couple thousand watts will be just fine for powering your tailgate, small appliances, and small machinery. If you want to power larger appliances like refrigerators, you need at least 3,500 watts. And for tasks like powering your AC unit in your camping RV, you need at least 7,500 watts. Each task is different, so make sure you know what you’ll be using your portable generator for before making a purchasing decision. We made sure to include generators in our selections that could cover virtually all of your needs.


You also need to consider the different types of outlets you’ll need on your generator. Your smaller options are typically going to have at least two 120V AC outlets and some USB ports. As you look at generators with increased power levels, typically more of these 120V outlets are available, plus you should start to see some 240V plugs as well. For outdoor usage, make sure to look for an option with outlets that are GFCI protected.

Extra Features

Extra features are always nice on portable generators, so we looked for the features that are going to add significant value to your experience. They included items like: wireless remote starters, multiple outlet options, USB adapters, electric starters, safeguards for engine health, and more.

Noise Level

Generators are known to make a lot of noise, and if you have one inside your home or at your tailgate powering appliances, the excess noise can be a nuisance. We eliminated generators from our consideration that were excessively noisy. The ones that came out on top for us passed our noise level tests, without sacrificing on quality. The average portable generator hums between 50 and 60dB, which is about the same noise level as a central air conditioning unit that is 20 feet away.

Fuel Type and Run Time

In most use cases, you need your generator to last you more than just a couple of hours. We looked for generators that at least met the average run time for their wattage level, and had features included that can help you save fuel and use it efficiently. Several portable generators these days come with automatic idling capabilities to save fuel when they can.

The run time of your generator also depends on the type of fuel you use. Most options these days are gas-powered generators. However, diesel fuel generators will typically give you better mileage for the volume of fuel you put in. Solar powered generators are also becoming more common. If you’re interested in solar power, be sure to check out our research on American made solar panels.

Easy to Start and Use

Your generator should be relatively easy to start and operate. If you can afford it, electric starters are the way to go – they just make your life so much easier versus pulling that recoil cord every time. We also looked for generators with EFI (Electronic Fuel Injection), which gets rid of your need for a carburetor and also makes your generator easier to start when it’s cold outside.


We want to make sure that you’re getting the best portable generator for your money. We eliminated several generators because we thought their quality didn’t live up to their price tag.
