WEN 56200i 2000-Watt Portable Inverter Generator

This particular heavy-duty inverter generator has so many great features that we couldn’t help but choose it as one of the best inverter generators on our list.

The WEN 56200i portable generator comes with many great features that you will become speechless.

First of all, it comes with 2000 starting watts and 1600 running watts, which pretty decent given its price range, and let’s not forgets its 79.7cc 4-stroke engine, which is responsible for its silent operation.

Due to its small size, this portable generator can also be used for tailgates, campgrounds, construction sites and, as well as power outages.

What I like most about this inverter generator is its clean power output using which you can run almost any sensitive electronics, including power tools.

You will get four output receptacles in this generator inverter on the market, such as two 120V ports, one 12V DC port, and one 5V USB output port.

You will be surprised to know that this particular heavy-duty generator is extremely quiet, and even at a 25% load, it produces as low as 51 decibels of noise.

The average runtime is 6 hours on the full gas tank as a 50% load, and it weighs around 48 pounds.

    • User friendly

What We Didn't Like
  • Expensive and heavy

Champion 6250-Watt DH Series Open Frame Inverter

If you are looking for high power output best inverter generator with high runtime, then this one’s for you.

It can produce 6250 surge watts and 5000 continuous watts and the average runtime is 12.5 hours when you use gasoline.

Some of you may not like this generator because of its bulky design and heavyweight.

But inverter generators are designed to be portable and lightweight, and their power-producing capacity is low because their internal circuit cannot handle high power.

So that is why if you need high power output from your inverter generator, then its size is definitely going to increase.

That being said, this generator has a built-in wheel kit and solid outer frame to make the transportation process very easy and efficient.

It has 4 gallons of the fuel tank, and it uses the recoil start method, which is not that bad.

There are some downsides to this generator too. For starters, it does have an RV-ready port and parallel capability.

This generator can produce enough power to run almost any appliance in your home so I would say there is no need for a parallel capability feature, and as for the RV ready port, you use the standard port to RV port cable.

    • Lightweight and quiet

  • No RV ready port

Pulsar PG2300iS Portable Inverter Generator

Pulsar PG2300iS is more of a portable and low-power output inverter generator that is very affordable compared to other inverter generators that have the same power output.

Pulsar is a very reliable brand, and most of its customers swear by its products.

The PG2300iS can deliver 2300 peak watts and 1800 running watts, and it can run for 6 hours continuously at a 50% load on 1.18 gallons of a fuel tank.

If this amount of power is not enough for you, then by using its parallel capability, you can connect two pulsar inverter generators together and increase the power output.

I really liked its compact and lightweight suitcase-type design, and it weighs less than 47 pounds.

This portable generator weighs less than 47 pounds, which makes it very easy to handle.

If we talk about the output ports, then the PG2300iS features two 120V receptacles, one 12V DC port, and one 5V USB port.

The only thing I did not like about this inverter generator is its short warranty.

Other manufacturers are offering two to three years of warranty at this price range whereas Pulsar is only offering one year of warranty on this product.

  • Low power output and small fuel tank

Champion 3400-Watt Dual Fuel Portable Inverter Generator

This generator is considered to be one of the best among all the inverter generators on the market due to its mind-boggling features and easy use.

What makes one of the best inverter generators stand out from others is their dual-fuel capability.

There are only a handful of dual-fuel inverter generators available on the market, and This Champion generator is one of them.

With the dual-fuel system, you can increase the runtime to a great extent, and also the propane is cheaper; hence you will be saving a great deal of money on fuel costs.

If we talk about the power output, then it can deliver 3060 starting watts and 2790 running watts using the propane, and the generator will run for 14.5 hours at 25% load when using a 20-pound propane tank.

You can increase the power output up to 3400 starting watts and 3100 running watts by using gasoline, and on a full gas tank, you can expect about 7.5 hours of runtime at 25% load.

Moreover, the generator operates at 59 dBA from 23 feet, which is quite low. Other than that, it has some other great features as well, including a 3-position ignition switch, quick touch panel, and low oil shut-off.

Additionally, it comes with RV ready port as well as parallel-ready output to double the power output.

Just like all their products, Champion has also included three years of warranty.

What We Didn't Like
  • Some users reported that the Rainier after-sale support is very slow

Rainier R2200i Super Quiet Portable Inverter Generator

Rainier is another well-known brand in the generator industry, and its inverter generators are very affordable.

If we compare its power output and features to its price, then I would say it is a reasonably priced product.

Thanks to its, 79cc 4-stroke engine, this generator is capable of generating 1800 continuous watts and 2200 surge watts.

And with 13 hours of runtime, you can easily run any appliance overnight, and the generator is incorporated with 1.3 gallons of a fuel tank.

Sadly, it does not come with an electric start feature, but instead, it features the recoil start.

You will love its Eco-mode feature that will help you conserve fuel, and thus, you will get maximum fuel efficiency.

That’s not all; if you don’t like noisy inverter generators, then you will fall in love with this best inverter generator.

The R2200i barely produces noise as low as 52 dBA and not to mention its clean power output, which is essential for running sensitive electronic devices.

Furthermore, the generator includes some other interesting features as well including low oil sensors, overload protection and not to mention the various output ports such as two 120V receptacles, one 12V DC port and, one grounding port.

Although, Rainier R2200i is not heavy (only 44 pounds), still the manufacturer has included one handle at the top for the user’s convenience.

It has all the necessary certifications, including EPA and CARB, so it is safe to use anywhere, and you will get three years of warranty on this best inverter generator.

What to look for before buying the best inverter generators?

There are some factors you need to consider before purchasing inverter generators.

Here, we have explained some of these factors.

Power output

The first thing you should look at inverter generators when purchasing.

You need to decide how many watts of generator you need.

For that, you need to make a list of appliances; you will run off of your generator.

After calculating the total wattage of all your appliances, add 15 to 20 more in it to make sure you can still use the inverter generators in the future.

Noise Level

No one likes a noisy generator. As you know, all the inverter generators are quieter compared to conventional generators.

Moreover, the noise output of inverter generators depends on the load condition.

As the load increases, the noise will also increase.

If you need a really quiet generator, then check out our list of inverter generators, and I am sure you will find a good fit for you.

Parallel Capability

If you are like me who likes to enjoy the clean power and quiet operation of the generator, then inverter generators are best.

But on the other hand, most of them come with low power-producing capacity, so the parallel capability is a must-have feature for such inverter generators.

Runtime

When it comes to runtime, the inverter generators have a trade-off.

Almost all the inverter generators have 0.5 to 2 gallons of the fuel tank; thus, its run time is very less.

However, by choosing dual-fuel inverter generators, you can eliminate this problem altogether.

So, in the end, it all comes to your personal choice.

Portability

A general rule of thumb is that the size of the inverter generators increases as the power output increases.

So if your high power output inverter generators, then you will have to sacrifice the portability.

Many inverter generators come with decent power output, and they are portable at the same time.

Frequently Asked Questions (FAQs)

Question #1. What size inverter generators do I need?

Answer: It depends on how many appliances you are going to run simultaneously.

So to know the exact power consumption, you need to calculate the starting watts and running watts of all your required appliances, and then, and only then, you can decide how many watts of inverter generators you need.

Question #2. Which is the difference between inverter generators and conventional generators?

Answer: Conventional generator directly produces the AC power, whereas the inverter generator produces AC power, then converts it DC power and then again inverts it back to AC power.

This additional power conversion results in clean power output, low noise production, and improved fuel efficiency.

Question #3. Can inverter generators run in parallel?

Answer: Most of the inverter generators come with parallel capability, so yes, you can run them in parallel.

However, with additional setup and parallel wires, you can also run one non-inverter and one inverter generator in parallel.
