The quietest portable generators are also called Inverter generators and it is based on a new technology recently introduced on how generators work. You can easily identify a quiet generator by just looking at their compact sizes and sleek designs.

The 5 points that make these generators create are:

  • Quieter than the average generators.
  • You’ll get cleaner power with much less distortion.
  • Much more compact.
  • Easy to carry (lighter weight).
  • The best for any adventurous activity like tailgating, camping, boating or even hunting.

Comparison Points Between: Inverter Generator & Conventional Generator? 

Many people prefer to have inverter generator than the conventional due to lightweight, efficiency and much quieter. What’s more interesting on how it actually works, which I will shed lights on that later. But let me brief it to you in two main points:

1- It creates electricity based on the use of magnets instead of heavy copper coils.

2- After it creates multiphase AC power it converts it to DC and then back to an HQ AC.

Why is an inverter generator lighter than a conventional generator?

The technology of rotating magnets generates the same amount of electricity without the need for copper coils in the rotor or a stator like what all conventional generators have.

That said, when you take out all the copper coils, you’ll find it bulky and heavy.

Many of the new inverter generators are surprisingly small and lightweight for the electrical generation punch that they pack.

1. HONDA EU2200I INVERTER GENERATOR

Honda-eu2200i-portable-generator

After the upgrade, this generator became the star and made it on top of the list.

Seriously, this generator so quite that your neighbors will hardly notice the sound. Not to mention, it is suitable for any occasion you can use it at home, camping, on the job site, or much more.

It has the Honda GXR120 engine, which gives it more power and weighs less than 47 pounds. That’s almost half the weight of a conventional generator.

Honda introduced the Eco-Throttle System in this EU2200i, this means you’ll have great fuel efficiency. You should expect it to run up to 10 hours on a single tank, depending on the load.

It starts at 2200 watts and continues on 1800 wats, plus it has multiple power outlets. So you’ll be able to power a wide range of appliances without a hassle not to mention it is also suitable for sensitive devices.

One of the lowest emission producing generators on the market, 100% CARB compliant and your reliable source for power in nearly any situation. If you want more power you can effectively connect two of this generator together and get the 2x powerup. Honda’s generators are well-known for producing excellence.

Benefits:

  • In addition to cleaner power (less electrical noise, voltage fluctuations, and frequency variations) an inverter generator can be more fuel efficient because it does not need to run at a fixed speed.
  • Incredibly quiet at eco throttle with minimal load, noise does increase as you approach its 15A running load capacity. But the unit itself is extremely smooth with no vibrations at full power.
  • Increased ventilation along the bottom of the front panel, presumably to keep the inverter and other circuit boards running cooler to avoid that failure path.

Downsides:

  • Lacks a DC 12V charging circuit and receptacle for automotive-type battery charging
  • It comes with a heavy price tag.
  • It does not come with oil, so make sure you have some.

How To Find The Most Suitable Inverter Generator For Your Needs?

Well, you are already halfway there, since you decided which power source generator you are looking for. So now choosing between the best portable inverter generator is what you need. And it is fairly simple.

So Here are the questions you should ask your self:

  1. Where Do You Plan To Use The Inverter Generator?

If you have a certain place in mind that you will use an inverter generator for quite often then perhaps you need to check the matched power requirements for the intended use.

RVs and Cabins:

When you are running various devices simultaneously you’ll be needing at least 2000 watts inverter generator or higher. Anything lower than this just won’t do. Plus it is vital to consider getting one with linking feature. So that if you would like to upgrade in the future and get a 2nd generator you can link both together. This gives a 2x power output.

Camping:

When it comes to camping in the woods, you’ll require something compact, lightweight, with a handle and easy to use. And getting 1000 watts or less is enough for an average camping trip.

Home Back-up Power:

It any outage event you need a reliable inverter generator that can take care of most appliances in the house. For example one fridge, three fans, cell phones, laptops, TVs, lights & coffee pot. For this case, you’ll need at least 1000 watts. If you have a bigger house with 2x appliances of what I mentioned you better stick with 2000 watts.

  1. How Long You Plan To Run It For?

So in the case of runtimes, the more runtime you are getting the less portability you are having. Simply because the gas tank gets larger. Most inverter generators are from .5 to 2.0 liters of a gas tank.

That’s why in this case, it’s up to you to decide which is vital to you. Portability or more runtime?

  1. Would You Want To Carry it Or Drag It?

So when it comes to portability of generators it can be two different options:

1- With wheels and heavy to lift (more than 80 lbs).

2- Easy to lift and compact (around 40 lbs or less).

Honestly, if I’m just going to go for home backup-power generator, I would just opt-in for more run time and wouldn’t give much emphasis on the compactness or design. At the end of the day, it boils down to your personal preference on that.

  1. Easy To Use Or More Technicalities?

If you haven’t used a portable inverter generator before or not familiar with the way it works, you will be definitely needing features that make it less of a hassle, like:

  • Low gas shut off
  • Gas meter
  • Low oil shut off

Most inverter generators now come standard with these options. But always check to make sure.

  1. How Much Noise Can You Take?

If you are living in a quiet neighborhood perhaps choosing a noisy generator wouldn’t be a suitable idea. Luckily most inverter generators are considered quieter than conventional generators.

However, there is still a significant noise different between inverter generators. Thus, it’s vital to check the noise rating on each device.

Rule of thumb: Any invertor above 60 decibels (dB) at half load is not recommended for a quiet friendly generator. I would usually go for anything below 50 Decibels (dB).

  1. How Much Can You Afford?

I’m sure that you are aware inverter generators are generally extra costly than conventional ones.

But with extra cost comes better quality, ease of use, quieter and more versatile power source.

Also, don’t forget any of the mentioned features above comes with a cost. Thus, it’s vital to keep the cost-feature ratio in mind and find the sweet spot that suits your needs.

Here Are 4 Mistakes To Avoid When Buying An Inverter Generator

Avoiding these mistakes will ensure you get the right product, at the right price.

  1. Make sure about which brand are you purchasing from, do they have reliable customer service. Don’t overlook that as usually something along the way with any generator needs proper support from the brand behind it.
  2. Beware of refurbished inverter generators, most of the time they are not reliable, I would prefer to stick to new ones.
  3. 2 or 3-year warranty is always great. Make sure you get this with any purchase.
  4. Buying online is the way to go when it comes to getting the best price. You’ll still get the same benefits as when you get it from a retail shop.

Bottom Line

Don’t forget to read user reviews and see their experience on that generator you chose. Amazon reviews are great and give a really rich experience of how people are dealing with the product.

However, I have to say that, the best inverter generator for so and so doesn’t have to be the best for you. As your needs might be totally different. So hope this portable inverter generator guide is useful for your buying decision.
