Cons

  • Requires the Honda EU220i Companion to run 13,500 BTU AC
  • Higher end price point

The Honda EU2200i portable generator is highly recommended when it comes to camping in your travel trailer or fifth wheel when not connected to a built in power source.

This portable RV generators comes highly recommended and is one of the most widely used portable generators readily available on the market.

The Honda EU2200i, when used without a companion, can steadily run much of your RV's entertainment, including the TV and DVD, satellite, refrigerator, coffee pot, and more! If you need a bit more power, you can parallel with the Honda EU2200i Companion to get 4400 watts.

Alone, the Honda EU2200i can run a small 8,000 BTU RV air conditioner but can run a 13,500 BTU RV air conditioner when paralelled with the companion.

One of the best things about this generator is that it's super quiet! At only 48 to 57 dBA, this Honda is one of the quietest portable inverter generators on the market! With a low dBA, you can have a normal conversation without the Honda generator roaring over you.

Another great feature that any RVer can appreciate is the Honda's fuel efficiency. With less than a gallon of fuel, the portable Honda EU2200i can run up to a staggering 8.1 hours!

Easy to use

Not only should your RV generator be reliant, especially when dry camping, but it should also be easy to use.

The folks over at Honda made sure that the EU2200i was extremely easy to use and user friendly. This Honda generator is equipped with an automatic mechanical decompressor system that significantly reduces the amount of force required to start it's engine.

One thing you may find extremely useful is the generator's fuel shutoff. The Honda has a "fuel shutoff" position that allows the generator to continue running off until the remaining fuel in the carburetor is used, which is intended to help prevent stale fuel. Left over fuel gums up the carburetor.

Personally, I can really appreciate the electronic circuit breaker feature. The Honda EU2200i's circuit breaker feature protects the generator from an overload which occurs when running too many watts.

You can boost that power by running it in parallel with another generator. Still, you'd be better off spending the extra money on an upgraded generator if you need the extra power.

Furthermore, it has a small fuel tank and only gives you 6.5 hours per tank while running at 50% capacity. While this is an extremely high-quality Japanese built generator, it's a bit of a disappointment for what you're paying.

However, it will last for years to come. If you're looking for a low maintenance RV generator that will fire up year after year, it's hard to beat a Honda.

4 Important Things To Consider Before Purchasing an RV Generator

Before purchasing a generator, there is quite a bit to understand about generators, your RV and what it takes to actually use a generator to run your RV.

1. Electrical Systems and Power Requirements

There are two different types of RV electrical systems; a 30 amp system and a 50 amp system.

30 amp and 50 amp RV plugs

A 30 amp system is typically used on RVs with a lower load capacity. This system has 3 prongs which are a single ground wire, a single 120 volt hot wire and a single neutral wire.

A 50 amp system provides an RV with a maximum of 12,000 volts, which is for a much larger load capacity. This system has a single ground wire, two 120 volt hot wires and a single neutral wire.

Knowing your electrical system is essential in determining the size of the generator needed to run your RV.

If electrical systems just aren't your thing; keep it simple and know whether your RV is equipped with a single AC unit or a dual AC unit.

A single AC unit is indicative of a 30 amp electrical system and two AC units is indicative of a 50 amp electrical system.

Note: Even though your RV is only equipped with a single AC, it may be prepped and wired for a secondary AC which would also make your RV a 50 amp electrical system. Check your owner's manual or the manufacturers website for this information.

Still unsure? Check the sticker above your RV's power cord as seen in the photo below.

1,500 - 2,000 watts

15,000 btu

3,300 - 3,500 watts

1,300 - 1,800 watts

Knowing this information will assist you in deciding the appropriate size of the generator need to run your RV.

3,000 Watt RV Generators

will start your RVs 13,500 btu air condition and will allow you to run a few small items.

(RV fridge, microwave, TV, coffee maker, etc.)

3,000+ Watt RV Generators

will start your 15,000 btu air conditioner as well as run a few small items.

(RV fridge, microwave, TV, coffee maker, etc.)

Two 2,000 Watt RV Generators

will start your Rv's 13,500 btu or 15,000 btu air conditioner as well as run several appliances.

4,500+ Watt RV Generators

will start your 13,500 btu or 15,000 btu air conditioner in addition to providing plenty of power to for the rest of your RV's appliances.

5,000 - 6,500 Watt RV Generators

will start and run your RV's dual AC system as well as provide plenty of power to the rest of your appliances.

2. The Types of Generators

When looking for the best generator to run your RV, you will come across two different types of generators; the conventional generator and the inverter generator.

Though we highly recommend an inverter generator to power your RV, we will briefly touch on the conventional generator and why the inverter generator is the "ideal RV generator."

Conventional Generators

Conventional generators, though not typically recommended, can be used to keep an RV running.

Conventional RV generators come equipped with a larger fuel tank than most inverter generators but are often bigger, bulkier, and heavier.

Though they have a large fuel tank, conventional generators are not very fuel efficient due to the fact that they run at a constant of 3600 rpm, regardless of their power load.

One of the more convincing reasons that conventional generators are not typically recommended for RV camping is their high decibel levels (sound level) usually ranging from a low end of 80 dB to as high as 100 dB depending on the size of generator being used.

Inverter Generators

When compared to the conventional generator, inverter generators are by far the more ideal "RV generator" of choice.

The "small" and "recreational" sized inverter RV generators can weigh as little as 50 pounds which truly make portable and easy to store away when necessary.

Like your conventional RV generators, inverter generators will also have a "fossil fuel tank" as well as a battery, alternator and inverter. Because of the electrical components involved with an inverter, the electrical output is much "cleaner" than their conventional counterparts.

This cleaner output means that running your RV on an inverter generator will supply it with a steadier more efficient flow of electrical output. 

3. Noise Level

When shopping for an RV ready generator, it is extremely important that you take into consideration the generator's noise levels especially if you plan on camping next to guests or staying at one of the many campgrounds across the country that put strict noise pollution restrictions into place.

According to a Portable Generator Noise Assessment by the United States Depeartment of Agriculture, The National Parks service does not allow generators to run at 60 dBA at a 50 foot level.

It is best to contact the campground, of which you plan on visiting, ahead of time in order to fully understand their campsite rules and regulations on RV generator noise pollution.

Tips on Properly Handling a Generator When RVing

Generators are heavy equipment and should be treated as such.

Keeping your family and yourself safe should be your number one priority when handling your RV generator.

Below are a few tips and steps on properly handling your new generator.

Fueling your generator

Since most portable RV generators run on gas and/or propane, you need to use caution when handling and using it.  Gasoline and propane are obviously extremely flammable, so be cautious when fueling and starting your generator.

  • When filling your generator, allow for the fuel to expand so as to avoid overflow. If you overfill your generator, you run the risk of leaking feel onto the engine which can easily cause a fire.
  • Always refrain from refueling your generator while it is running.
  • Before storing your generator, make sure to empty the tank completely so as to avoid excess fumes.
  • Do not run your generator next to a campfire.
  • Do not handle a running generator. Running generators can become very hot and cause burns.

How to Safely Store and Operate Your New RV Generator

Where you put your portable generator and operating it safely are very important.

Always use your generator outside or in a well ventilated area. Never start or run your generator while on the inside of your RV or while the generator is in an exterior storage compartment.

While running, the generator exhaust will give off carbon monoxide which is an extremely toxic gas.

Always check your carbon monoxide detector and make sure that it is live and in good working order.

Generators are not safe for children to be around in any way.  Make sure that no children or pets have access to it and keep them away from it at all times.

  • There should be at least 5 feet of clearance on ALL sides of the running generator.
  • Generators can be used in many different kinds of weather and temperatures but protect it from the elements when it isn’t in use so it doesn’t rust or short out.
  • We will state this again…NEVER use a portable generator inside your RV or in a garage or storage compartment.
  • Make sure the space you set up the generator is level and it needs to be protected from excessive moisture, dirt, dust and corrosive vapors.
  • Make sure that you inspect your generator before using and after using (once it is completely cool) to make sure it is running properly and in good repair. If anything is not as it should be, take care of it right away so it is in good working order when and if you need it.
  • Perform routine maintenance on your portable generator according to the owner’s manual for your model. This keeps it in great working order so it’s ready when you need it and also helps it last longer. If your model comes with a warranty, this keeps the warranty intact as long as you adhere to the stipulations of routine maintenance and don’t do anything it states not to.
