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.

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.

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.

The EU2200I Is Parrallel-ready

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

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.

This generator is lightweight and compact, making it ideal for tailgating and camping.

It’s parallel-ready and CARB compliant.

It has inverter technology, so even sensitive electronics will be safe. With a 500W load, this Yamaha generator will last around 8 hours.

The fuel efficiency is possible thanks to the smart throttle system, which also reduces noise.

Yamaha includes a number of features that make it user-friendly, like a fuel gauge, a low oil light, and an auto-decompression system that means an easier start.

The second version of the EF2000IS is very popular, I think this is the best portable generator from Yamaha in this price range.


  • Compact & Lightweight
  • Relatively Quiet
  • CARB Compliant
  • Parallel-ready
  • Fuel Gauge
  • 2 Years Yamaha Warranty


  • Need to unscrew the panel to fill oil

Champion Dual Fuel Inverter - Best for RV, High power & Electric Start

Most generators have pull cable recoil starters, so a generator with an electric start always feels like a treat.

Just turning the 3-position toggle switch is just so much easier than yanking on a cable and it’s especially nice for those with injuries or a general lack of upper body strength.

At first glance, this generator looks almost like some kind of kid’s toy. Up close, that bright yellow panel is really very clear and easy to understand with everything clearly labeled.

Rated for 3100 watts, this generator has enough power to handle a lot.

It’s an inverter so your sensitive electronics will be protected with that clean energy.

This is a dual-fuel portable generator so you can use either gasoline or propane.

This Parallel-ready generator can run on Propane or Gas out of the box!

It has decent fuel efficiency, with a tank of gas getting you up to 7.5 hours. Noise isn’t a problem.

In fact, it’s surprisingly quiet, given the amount of power it has.

This portable inverter is a great choice for the RV with its RV-ready outlet.

It will also work well on a worksite or as a backup power source for your home. The Champion 3400-Watt generator is quite heavy at nearly 100 pounds, but it does have tires, and a pull handle built right in, so transport isn’t all that difficult.

Briggs & Stratton 30545 P3000 - Convenient and Versatile

This generator from Briggs & Stratton offers both power and convenience.

It weighs 85 lbs, but it has wheels and a telescoping pull handle. It has four standard household outlets, more than most other generators offer.

There is also a 12-volt 30-amp locking outlet with RV adaptor, a DC charging outlet, and a USB port.

This makes it an ideal generator for a number of situations, from a backup home power source to tailgating or camping to RV use.

A 1.5-gallon fuel tank gives you enough juice to last over 10 hours on a 500-watt load.

A special quiet power technology setting will automatically adjust the engine speed, resulting in less noise.

This mode will also save fuel and increase run-time.

One really nice feature of this generator is the LCD display screen.

This shows things like the current amount of power being used and also notifies you of when it’s time to perform various maintenance tasks like changing the oil or spark plug.

The P3000 portable generator is rated for 2600 watts (running watts), but you can effectively double that by running two of them in parallel.

One downside to this portable generator is that it is not CARB compliant.

Because it doesn’t meet their strict emissions guidelines, this generator can’t be shipped to California. It is a transportable inverter that offers safe and clean energy for powering electronics.

The P3000 is the best portable generator around the 3000W power range.


  • 4 Power Outlets & RV Ready
  • Quiet power technology
  • LCD display
  • Wheels and pull handle: Easy to carry
  • More Power than the average generator this size


  • A bit heavier
  • Not CARB Compliant (can't be bought from California)

WEN 56200i - Quiet & Convenient

This generator from WEN offers clean energy, with the inverter mimicking a pure sine wave.

It is also EPA and CARB compliant and has very good fuel efficiency.

The quiet operation is a major selling point for this mobile generator. At a quarter load, it only registers at 51 decibels, about the same noise level as a typical conversation.

This ultra-quiet operation makes it a great operation for things like camping where you don’t want to disturb others near you.

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.


  • Affordable
  • Eco-mode Operation
  • CARB Compliant
  • Lightweight & Easy to carry


  • No fuel gauge
  • I find it a bit bulky, even though it's lightweight

Rated for 2000 watts, it provides more power than many similar generators.

It offers clean and safe energy with inverter technology.

This portable generator typically starts quite easily because of its high current output. This makes it great to power high starting watt appliances like an air conditioner.

It uses Pulse Width Modulation for stable and clean energy that is safe for electronics.

The speed of the engine will automatically adjust with the smart throttle technology, resulting in better fuel efficiency and less noise.

This portable generator does have a fuel gauge and a low oil warning light.

The cast-iron cylinder liner helps protect the engine and keep it running well for years. Yamaha is also known for making excellent engines.

The 5.5 HP engine provides a lot of power and reliability, but it will also burn more fuel than a lower-HP engine.

Like with the Yamaha EF2000iSv2, this portable generator is another example of a reliable, powerful tool that also has a great looking design.

This model is heavier and a bit bigger than the EF2000iSv2, but it has a similar aesthetic.


  • Dual handles for easier transport
  • Best portable generator to power an aircon
  • Sturdy, excellent construction
  • User-friendly control panel


  • More expensive
  • Only 2 AC Outlets

Energizer eZV2000P - It Keeps Going and Going

Like the Energizer Bunny, this portable generator just keeps going and going.

With a 500-watt load, you can expect it to keep going for over 9 hours.

It will even last quite a while when running at 100% capacity. Rated for 1600 watts, this generator can handle sensitive electronics and is parallel-ready.

It doesn’t have RV-capability built-in, but you can buy RV outlets to use with it.

Sportsman Portable Generator - The Cheapest One With Some Problems

This generator looks exactly like how you might expect a generator from a brand called Sportsman to look: rugged and camo green (click here to read my full review).

This generator is only rated for 800 watts, so it’s not going to have enough power for a lot of uses, but it should be enough for some camping and tailgating use.

It has a very low price tag to compensate for the lack of power.

The overall quality of construction in this portable generator is also a bit lacking, though, with some cheap plastic housing that might not stand the test of time.

However, at that price level it is hands down the best portable generator.

It does feature inverter technology so it can handle electronics like laptops or cellphones.

It is CARB-compliant. The 0.55-gallon fuel tank will last for just over 6 hours at a 50% load.

This is one of the louder portable generators. It’s 56db when it’s on but not running a load at all, which is quite a bit louder considering the wattage.


  • Most affordable option on the market
  • Compact and easy to carry around
  • CARB Compliant


  • Not much power
  • Smaller gas tank
  • Cheap plastic construction
  • Assembly required
  • Only 1 Year limited warranty

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.

Fuel Type

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.

Noise Level

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?

In some cases, you may be able to repair a generator yourself if you’re generally handy and have some basic technical repair skills. There are some helpful online resources, like this video.

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?

The answer depends entirely on the size of your air conditioner. For most air conditioners, you’ll be looking at 2800-3500 starting watts and 1300-2000 running watts. The Yamaha EF2400iSHC uses a high current that can easily start a high efficiency 13,500 BTU air conditioner even in temperatures up to 110-Degree F.

Can I use an extension cord?

There are a lot of situations where an extension cord will be necessary. For example, if you want to use your generator to power an indoor appliance, you’ll need to run an extension cord outside to your generator. It’s important to only use a heavy duty 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?

Yes, building an enclosure for your generator can be a very good idea. A major reason for building an enclosure is to reduce the overall noise level. An enclosure can significantly bring down the generator’s total noise level.

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?

That depends on what exactly is meant by an entire house, but the answer is likely no. You should be able to run a handful of small appliances in the home but there is no way that a portable generator has enough power to run the entire house’s power.

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?

You should always follow the manufacturer’s recommendations for all maintenance. Typically, you’ll be told to check the oil before every use. After so many hours of use, it will be time to change the oil. For the Generac GP2200I, it’s recommended that you change the oil after 50 hours of use.

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?

If you find that your generator is not running and it won’t start, you need to make sure that the wire is securely connected to the spark plug. If you see that the plug is covered in an oily liquid, it is getting too much fuel. If you have a gas generator, make the oil level is maintained. Another common problem is a broken pull cord. It is rare, but when it happens, you can easily replace the cord.

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?

Yes, in fact, it’s important that you keep your generator at least 15 feet away from your house. It’s vital to keep a healthy distance in order to prevent carbon monoxide poisoning. You should never run your generator inside a closed area like a home.

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

There you have it these are the best generators for the money.

Hopefully, this portable generator buying guide has helped you figure out which generator is the best option for you and made you aware of things you should consider.

Once you use a generator, you’ll wonder how you got along without one before.

Just remember that it’s important to take good care of your generator and perform routine maintenance.

Portable generators offer good value, but they are still an investment, so you should protect that investment.

  1. Hi Matt, what an excellent web site. Thank you for sharing your insights and experience.

    Have you take a closer look at the Honda EU3000IH1A and the Honda EU3000IS1A?

    Aside from the obvious differences, what are some of the finer items that I may not notice from the general literature.

    • Hi, thanks for your comment! EU3000IH1A is a bit louder, while the EU3000IS1A’s GX200 motor is a bit more powerful, and offers twice the fuel capacity and runtime (also 2 times heavier)

    • The EU2200i is about 200w more powerful with a different engine (Honda GXR120 four stroke engine), it is also slightly quieter but the difference is too small to really notice. It is a better choice overall I will put up a review soon. I believe Honda is going to discontinue the EU2000i.

  2. Hi, I’m looking to purchase an electric generator, one that you can plug in and charge. It will be used to plug in a heater. I run a forest school so the children are outdoors most of the day, when it’s really cold they go inside our log cabin to keep warm. I know nothing about generators so your advice would be much appreciated. Thank you

  3. Matt – did you ever try a Cat INV2000 too….. Weird how it gets little to no publicity. Is it because it is a bit overpriced, with a Harbor Freightesque motor….

  4. Matt,
    Recently relocated to FL from CT. Living in rural Ct we always had a General whole house standby generator (16 kw) with a transfer panel. With this experience I wanted to firewall my home here in FL as well,due to the incidence and length of weather related power outages. After an initial investigation it appears that permanent stand by generator is not practical because of prohibitive HOA rules re: fuel. Therefore, can you suggest the ,most reliable and powerful portable generator (assume that we will NOT power the AC or electric stove to the generator to avoid overloading the system. It should have an electric start and multiple fuel options and be able to connect to a transfer switch.
