A portable generator can be picked up or moved easily. It generator may have wheels or a handle but can be moved by one person.
I created this website to learn more about smaller, quieter generators, both gas & battery-powered, to use on my camping and RV trips. The 10 best portable gas generators listed below come from my research and personal experience. I own many of the gas generators and nearly all of the battery-powered generators reviewed on GeneratorGrid.com.
A generator is something that’s good to have on hand because you never know when you might need it!
Here are the 10 best portable gas generator options on the market right now.
1. Honda EU2200i – The Best Portable Generator From Honda
One of the most popular 2000 watt portable generators, the Honda EU2200i (full review here), has multiple features that made its previous version (the Honda EU2000I) a crowd favorite.
This is the main gas generator I use when camping, and boondocking around Oregon.
Perfect for home use, camping, at the job site, and many more applications, this Honda inverter generator can tackle a wide variety of appliances.
It’s high power output, and lighter weight makes it a solid workhorse for just about any job.
- This popular model can operate a wide variety of appliances, making it perfect for portable use at home, camping, on the job site, or much more. Reliable Power is now at your fingertips with Honda's Inverted Generators.
- So quiet, your neighbors will thank you. The EU2200i operates at 48 to 57 dBA, which is less noise than a normal conversation. This makes it ideal for camping, supplemental RV power and any other activity that requires quiet operation.
- Add a second EU2200i for additional power. Two identical models can be paralleled with an optional cable or cord for up to 4400 watts of power, or time-consuming applications.
While it is not as attractive as other generators, this generator makes up for it in many other important categories. To me, this is the best portable generator this year, a great successor to the all-time favorite EU2000I.
When measured at 23 feet, the industry norm, the Honda EU2200i only output 48 to 57 dBa.
As a comparison, this is fewer decibels than a normal conversation making it a great choice for those worried about noise control.
Most generators can exceed 70 dBa at 23 feet, making them somewhat of a nuisance for running overnight or with close neighbors.
With this generator, you can easily power appliances for long periods of time without worrying about noise pollution.
Honda has kept the end-user in mind and has designed this generator to be as user-friendly as possible.
The easy to use recoil start, convenient layout, and easy to read labels add to the many reasons why this generator currently has a 5-star rating with over 100 reviews on Amazon at the time of this article.
As with any portable generator, you are going to want it to be, well, portable.
That is where this EU2200i really beats out the competition, weighing in at only 40lbs.
This makes it really easy to transport it to any place you need power on the go. Featuring Honda’s exclusive Eco-Throttle System, this generator gets excellent fuel efficiency and can run 4-9.6 hours on a single tank depending on how much of a load is on the generator.
This generator features two AC out 120v 15A outlets and a DC 12V 8.3A to provide you with easy access to your power.
Honda has also included parallel ports to power two generators at once for up to 4400 watts of power.
It is also loaded with several different LED alerts that will warn you of any problems to prevent damage to your generator.
The oil alert illuminates when your oil level is getting low to keep your generator’s motor protected.
An overload alarm will light when there is a power overload that exceeds the capabilities of the generator, or there is a short circuit in a connected appliance.
Overloads can cause catastrophic failure to generators, and this is just another way Honda stands behind their products.
The last light is the output indicator light, and it will illuminate green when the generator is producing electrical power at the receptacles.
- Easy carry handle
- Excellent Honda Engine
- Three-year warranty by Honda
- Eco-throttle option
- No Fuel Gauge
The Honda EU2200i is the best portable generator according to customer reviews. A high performer in a small package. This is a great generator to have on hand when working around the job site, campsite, or even at home for a backup source during a blackout. I consider the Honda EU2200I to be the best portable generator for most people, as well as the most reliable portable inverter on this list.
2. Yamaha EF2000iSv2 – Performance & Reliability
When you think of a generator, the design is probably the last thing on your mind. Nonetheless, the Yamaha EF2000iSv2 (click to read my full review) manages to be quite beautiful.
The retro-inspired look and the royal blue hue aren’t just window dressing either.
This portable generator is a consistent best-seller from a very trustworthy brand. It’s rated for 1600 watts, and it’s remarkably quiet (click here to see the quietest ones), thanks to its muffler and spark arrestor.

An eco-mode option will result in the absolute quietest operation while also boosting fuel efficiency.
You won’t be able to operate at max capacity in the eco-mode, however.
The WEN 56200i (click here to read my full review) has two three-prong 120V receptacles, one 12V DC receptacle, and one 5V USB port.
It’s also parallel-ready. Transport is easy with this lightweight generator because of its convenient carry handle.
There is no fuel gauge on this portable generator, but there is an automatic shutdown feature if you are close to running out of either fuel or oil.
This is the best portable generator from WEN in this price range.
- Eco-mode Operation
- CARB Compliant

Portable Generators Buying Guide
There are many uses for a portable generator including using it for emergency power, running a job site, or other more recreational uses. With the many models and types of portable generators currently available, it may be difficult to narrow down your choices to find the best one for you and your situation.
Here are a few things to look for when choosing your next portable generator:
Power and Outlets
You need first to determine how much power you are going to need from your portable generator.
A refrigerator, for example, only requires approximately 700 watts to run, but it may need three times that to start up.
Outlets are also important. A smaller generator typically uses a couple of 120V AC outlets and maybe some USB ports. The bigger the generator, the bigger the wattage you will need. 4000 watts, for example, may require a 240V plug.
The most common generator is gas-powered, and fuel is pretty easy to come by if you need the generator for an emergency situation. Diesel generators, on the other hand, offer more in the way of fuel efficiency but may cost a bit more as well.
Battery-powered generators can be recharged using a solar panel, they are much quieter, and have zero emissions. However, these generators also cost more, may take a while to recharge, and typically don’t provide more than 1800 watts. They are the best for recreational use like when you choose to go camping or tailgating.
The Fuel Tank
If you have a bigger fuel tank, then the portable generator will run for longer. Many generators allow you power for 7-9 hours at a 50% load. You also must keep in mind that a larger tank also means the generator will be much heavier in weight, so it may not have the portability you are looking for.
Electric start engines are great, but they come at a higher cost. A lot of portable generators use lead-acid batteries like you would find in automobiles while others may use lithium-ion batteries. If you have a battery, it needs to be charged before use.
Smaller generators have super quiet operation while others are slightly louder. Again, a smaller generator is ideal for recreational use like on a camping trip because it won’t bother others around you. But when you start using the larger portable generators, you won’t find something considered “quiet.” A diesel fuel generator will also be louder than a gas powered generator.
Best Portable Generators FAQ
Who can repair a portable generator?
For most people, though, trying to do a repair yourself isn’t a great idea.
This is especially true if your generator is still under warranty, as trying to fix something on your own will disqualify the warranty. You should always have it fixed by a certified repair person.
You can find a list of qualified people through the manufacturer. You can also generally find help from any authorized dealer. Most experienced small engine mechanics should also be able to help with most common generator problems.
Can a portable generator run my air conditioner?
Can I use an extension cord?
It’s also very important to make sure the extension cord is in good condition without any cuts and with all three prongs in working order. As long as you use a heavy duty cord in good condition, it’s perfectly safe to use an extension cord with your portable generator.
Is it a good idea to build an enclosure for my generator?
Enclosures also protect the generator from the elements and prevent any dust or debris from causing damage. Making a DIY enclosure can be done pretty easily at minimal cost. There are a number of helpful tutorials available, including this video.
Can I run an entire house with one of these?
If you run two generators in parallel, you’ll be able to run more of the home. When using a portable generator as a backup power supply after a power loss, you’ll generally have to pick and choose what tools and appliances are more of a priority. You can use our Wattage calculator to estimate how much power you are going to need.
How often should I change the oil and what should I get?
For the Honda EU2000i, it’s recommended that you change the oil every 6 months or every 100 hours, whichever one comes sooner. You should always use the type of oil recommended by the manufacturer. Honda recommends SAE 10W-30 while Yamaha recommends 10W-40.
What are some common problems I may encounter?
There may also be a lack of air. The generator requires air to burn the fuel in the tank. The choke’s position needs to be in the proper place in order for the motor to start. If it is in the wrong position, your engine may not start.
Should I keep it at a distance from my house?
Safety tips & precautions when using a portable generator
- Never operate a generator indoors.
- When running, the generator should be at least 15 feet away from any open windows or doors.
- Don’t run a portable generator when it’s raining.
- Turn the generator off and let the engine cool before refueling.
- If using an extension cord, make sure it is heavy duty and in good condition.
- Install a transfer switch to safely power hardwired appliances.
Conclusion – About this guide
