That’s why you might want to consider Honda’s EU2200i companion inverter generator.

Today we will examine Honda’s popular companion model that works with the Honda EU2200i or 2000i so that you know if it will serve your needs. We will cover the basics, explore promising features and functions, and break down the pros and cons so that you can make an informed decision when it comes to purchasing your next piece of power equipment.

What is an Inverter Generator?

Let’s start with the basics. An inverter generator is a type of generator that adjusts its engine to meet demand instead of running at full power all the time.

The inverter technology means stable, clean power that will last longer and be more fuel-efficient. These types of generators tend to be super quiet while still allowing great fuel-efficient runs.

  • 2200 watts of power
  • 30A 125V Locking plug
  • 20A 125V receptacle
  • USDA qualified spark arrestor muffler


A weight of 47.4 pounds means that the companion is incredibly lightweight compared to many other inverter generators. The 30 amp receptacle makes it able to operate a wide variety of appliances and even RVs.

In some areas, spark arrestors are required for operation by the USDA. This generator meets that requirement allowing it to be used pretty much anywhere.

Features and Functions

The Honda EU2200i Companion comes with a lot of helpful features, including the following. Many of these features are improvements on previous models showing that Honda has a dedication to continuous improvement.

Bluetooth and Honda My Generator app

The Honda My Generator app gives you greater control over your portable inverter generator. With it, you can stop your generator wirelessly and get service reminders sent right to your phone.

It is currently compatible with both Apple and Android operating systems, so you can get this feature regardless of what type of phone you have. You need to be within a 75-foot line of sight for it to work, but it can control multiple generators at once.

The in-app instructions will get your phone paired to your generator in no time.

Honda GXR120 Engine

The super quiet Honda GXR120 engine powers this power equipment. This engine was initially developed for heavy-duty construction equipment, so you can rest assured that it will be capable of powering everything you need. With a lighter package, the precision this engine provides is unmatched.

Fuel Shutoff (fuel off position)

This feature allows the inverter generator to keep running until it consumes all the fuel and then shuts off. This technique helps prevent stale fuel. It is also beneficial when you want to store your generator for long periods without worrying about it.

CO MINDER: Carbon Monoxide Detection System

This feature constantly monitors the carbon monoxide levels in and around the generator. If these levels become dangerously high, the CO MINDER will automatically shut off the machine. This is crucial because carbon monoxide is a colorless and odorless gas that is impossible for humans to detect independently.

The CO MINDER is an invaluable tool that will save lives and give you peace of mind to operate your power equipment. No matter what inverter generator you end up going with, you will want to ensure that it has a feature like CO MINDER.

3-year Warranties

The EU2200i companion comes with not one but two 3 year warranties. One 3 year residential warranty and one 3-year commercial warranty will allow you to rest assured that no matter how you use your inverter generator, it will be covered. These warranties show that Honda truly does stand behind their product, which is always nice to see from a large company.


Oil Alert Protection

This feature protects your inverter generator by automatically shutting off the engine when low oil is detected. This crucial safety feature will help to keep your generator as well as yourself safe from harm.

Recoil Starting System

With a starting system recoil, it allows the EU2200i companion to be started quickly and easily. The starting system is color-coded so that even a complete novice could get the system up and running in a matter of moments.

The recoil rope on this model has also been revamped so that it is less likely to cause damage to the generator. Much less force is required than other models need. The starting system recoil fuel tank capacity is about a gallon of fuel.

Eco-Throttle System

The exclusive Eco Throttle system from Honda allows the inverter generator to have great fuel efficiency runs. It lasts up to 8.1 hours on less than a gallon of fuel. This 8.1-hour run time makes it perfect for running power overnight. This feature makes this model super quiet, smooth, and fuel-efficient, emitting less noise than a normal conversation.

The 8.1-hour run time is based on a one-quarter load. If you are running a full load, your run time will likely be 3.2 hours, which is still pretty impressive for such a small device from Honda.

Frequently Asked Questions

How Much Power Do I Really Need?

So we’ve covered that the Honda s inverter technology in the EU2200i companion can operate many types of appliances with smooth fuel-efficient performance, but how many things can be powered at once?

To figure this out, you must consider the starting wattage versus the running wattage. Generally, the starting wattage is the same or higher than the running wattage. Once the device is started, you only need to have enough wattage to cover the running wattage.

To keep your wattage requirements in check, consider starting appliances with high starting wattages at different times and turning off appliances when they are not in use.

If you determine that you need more power than a single generator can provide, you can parallel two together to get double the power. Keep reading for more information about this process.

What is the difference between the Honda EU2000i and Companion?

The Honda EU2200i delivers 10% more power without being much heavier or requiring you to pay more. The 2000i only afforded 2000 watts while the newer model gives an additional 200 watts.

While this may not seem like a big deal, it can be a godsend when you are just 200 watts short of being able to power absolutely everything you want to all at once. 200 watts might be all you need to power an extra hot plate and coffee pot at your campsite or an extra industrial fan while on a construction site. Once you get used to this extra power, you will never settle for less.

Don’t forget that you can enhance this wattage even further by paralleling your companion with another generator and doubling your wattage to 4400.

The EU2200i is less than one pound heavier than the EU2000i while still being quieter and offering a similar run time. The EU2200i provides an immense amount of power in a smaller, lighter package than most other models on the market today.

Can Honda EU2000i Companion be Used Alone?

Yes! The companion is perfect for RV use on its own, and it includes a special receptacle for RV applications. The built-in 30 amp for RV applications requires optional adapters, but the receptacle allows 2 EU2200i models to run parallel without requiring an external parallel kit. The EU2200i Companion offers one 30 amp receptacle, but it also offers one 20 amp receptacle.

Can You Parallel Two Honda Companion Generators?

You cannot parallel two Honda companion generators together; however, you can parallel the EU2200i Companion with another EU2200i model. In fact, the companion is specifically designed to do this. Connecting the EU2200i with a regular EU220i model will provide up to 4400 watts of power, double the amount of power that a single generator can provide. The EU2200i will also parallel with other models such as the EU2000iK1/T1.

Verdict: Should You Buy the Honda EU2200i Companion?

In short, I would recommend this product, and so would many others. Overall most people found that the pros far outweighed the cons. Most people that gave the EU2200i companion a try would also recommend this product. Regardless of whether they purchased it two months ago or five months ago, people found that Honda s inverter technology stood out among the rest.
