About A-iPower Corp.

If you are looking for equipment made by engineering and manufacturing giants with a worldwide branding impact, A-iPower may not be at the top of the list for you. It isn’t a tech giant like Honda or Caterpillar, but even then, it has made its mark by successfully competing against those giants with years of experience and technical depth. This company was founded almost 30 years ago and has since grown enough to develop a strong reputation for providing quality power solutions. 

If we look at the annual revenue of the company, it stands at $5.4 mil and is forecasted to increase. I got to know that this revenue is greater than the industry median. This shows that the company is trusted by its potential customers and is expected to grow by 25% during the next two years. 

A-iPower Product Categories

A-iPower excels at manufacturing innovative and cost-effective power solutions. The company started with designing and making water pumps, pressure washers, and initially but later expanded its product range to offer gasoline engines and portable electric generators as well. 

A-iPower focuses on performance and quality, which has considerably expanded its consumer base in North America and Europe. The technical department of the company is one of the best in the industry. It has been a building block for the developing reputation of A-iPower as a manufacturer of one of the most reliable ranges of portable generators.

What I found on the flip side was that the revenue generation per employee is a bit lesser than the industry average for A-iPower. In addition to that, their number of employees isn’t growing as fast as it should be, corresponding to their revenue growth. However, the company’s substantial market share will help overcome these weaknesses in no time.

Features and Ease of Use

A-iPower SUA2000iV looks like a reliable and handy inverter at first glance. But does it make the cut in fulfilling your needs all the while presenting you with quality features? 

For me, it certainly does. But after going through the specifications and features, it’s up to you to decide if it provides you the ease, quality, reliability, and functionality you are looking for.

Inverter Technology

This portable generator incorporates inverter technology. Full-wave rectification of raw DC power to AC allows the clean and safe output to be used for sensitive electronics like tablets, laptops, cellphones, and other power-sensitive equipment without any issue.


The inverter model also features a multi-switch that you can use for ‘Start’, ‘Run’ and ‘Stop’ functions. The switch provides you with convenience and ease of control by letting you operate the choke, fuel, and engine on or off.


Of all the inverter generators that I came across, this model was among the lightest. Weighing only 46 lbs, you can take it wherever ever you want to. It’s easy enough to carry by an adult, so no hassles in portability either.

Noise Cancellation

Due to this model being a close-frame one, the sound level isn’t as loud as open-frame conventional generators. This inverter produces a noise of 58 dB at 50% rated load at a distance of 21 feet, an impressive feature assuring the users of a quieter operation. 

The Eco mode further drops the sound level by adjusting the engine speed according to the required output.

Parallel Function

The parallel connection capability of SUA2000i allows it to link to another generator, of the same type, with parallel cables to double the output. 

The best part? You won’t be needing any external parallel kits, and the feature is already integrated to allow the convenience of operations.

Idle Mode

This feature is getting pretty standard in all high-end inverter generators. SUA2000i also uses this feature to adjust the engine speed automatically as per the needed output. This results in lower noise levels and efficient fuel consumption.

Indicator Lights & Fuel Gauge

The control panel has an output, overload alert, and low oil alarm three-in-one light indicators. In addition to that, there’s a built-in fuel gauge on the fuel tank to help you check the fuel level and remind you when the generator unit needs refueling.

Durable Engine

The inverter engine has been designed to last longer and have an extended run life using cast-iron cylinder sleeves. 

Extended Run Time

Having a fuel-efficient design, this inverter has an increased run time compared to other models with a similar output. The unit has a 1.1 gal fuel tank that provides a run time of up to 7 hours at 50% load. At 25% load, the run time can go up to 15 hours.

Low Oil Shutdown

The inverter shuts down automatically at low oil levels, thereby protecting the engine from potential damage. 


This inverter model is CARD and EPA compliant. Hence it can be operated, sold, and purchased in all 50 states without any technical/legal issues.

Output Ports

The control panel of this inverter houses one NEMA 120VAC 20A outlet, one NEMA 120VAC 30A, L5-30R twist-lock outlet, and one 12VDC 8.3A adapter plug. A 30 Amp RV adapter is also included.

Have a look at this overview video on YouTube.

Engine Specs for A-iPower Generators

A-iPower primarily uses two types of engines for manufacturing inverters with this kind of similar output, the 79cc and the 98cc/3hp OHV engines. For bigger models, the company uses 208cc and 389cc engines.

Let’s talk about the engine used in SUA2000i.

What Engine Is Used in A-iPower – SUA2000i Inverter Generator?

In this inverter model, the engine being used is the latest model A-iPower 79cc OHV engine, manufactured by Senci. From the reviews and information, I have found out that this Senci 79cc engine is a clone of the Yamaha MZ80 engine. While not being inferior in any way, Senci is a way more cost-effective product than Yamaha. So no downsides here.

Let’s go through the salient features of this engine.

  • Single Cylinder
  • 4-Stroke
  • Air Cooled
  • Cast Iron Cylinder Sleeves for increased run life and durability
  • Recoil Start
  • Low Oil Shut-Down

For more information on A-iPower – SUA2000i, you can go through the manual of this inverter generator here.

Fuel Type and Efficiency

The fuel you will use to run this engine is gasoline. Due to this model being considerably cheaper, dual-fuel technology wasn’t used. Hence unleaded gasoline is the only option.

Fuel Tank Capacity

The gasoline capacity of the fuel tank of this inverter is approximately 4.2 liters (or 1.1 gallons).

Why Is Gasoline Used for This Generator Unit?

As with most of the other generators, gasoline is used in this inverter generator as well. Gasoline, as a fuel, has several benefits that I will mention here.

Benefits of Using Gasoline

  • Gasoline produces more energy per unit of fuel than propane and natural gas; hence, it can be ideal for running the generator in low fuel and high power requirements.
  • Gasoline is considerably cheaper than propane if we compare the cost of per kW generation. That makes it more efficient in terms of economic values. On the flip side, natural gas is even cheaper than gasoline but gives out less energy per unit than gasoline, hence becoming impractical. 
  • Gasoline is readily available and extremely common. You won’t have to venture far to have your fuel tank filled. Propane may only be available at some specific locations in your vicinity.

How Long Will The Engine Run On Full Tank?

The calibration of run time with a full fuel tank hasn’t been done as per the industry standards (at 25% load cap) by the company as per the mentioned specification. But A-iPower claims that this engine runs for about 7 hours at 50% load with a full fuel tank of 1.1 gallons. 

Judging from this, the inverter should run for about 14-15 hours at 25% load capacity, while at 100% load, the engine runs for 4 hours straight.

Noise Levels

One of the most common issues that the users of portable generators are wary of is the extreme noise level during the operation. To make them more user-friendly, the companies face a race against time to manufacture them as noiseless as possible. This low-noise feature makes them a hot cake in the market for this very reason.

However, as A-iPower claims, SUA2000i isn’t as noiseless as a small, closed frame inverter should be. I have come across several other inverters with higher power outputs that were even quieter.

Here are the noise levels you’ll get in this model.

Variable Load Noise Level

Although the closed frame of this model includes a muffler to help dampen the sound, the noise level on 50% still comes out to be 58 dB at a distance of 7 meters (as per the industry standards). At 75% load, the sound level is at 68 dB. 

This sound level is good but not impressive enough to be compared to the quietest models out there. The noise it makes is roughly the average that an inverter generator with similar features is expected to produce.

The plus side is that the Eco mode can regulate the engine speed to match the required output, reducing the noise levels further.

Full Load Noise Level

This model goes up to around 72-73 dB at a distance of 20 feet at full load. Some may still say it’s quiet enough, and given the price of this inverter, the sound levels seem a pretty fair bargain.

Noise Reduction Technology – Comparison with Other Models

If we look at the generators made by A-iPower, the noise reduction does look like a thing but does not look like the point of their prime focus. In comparison with other similar models, the sound level of this inverter is still higher. 

If you want to go for another model deploying a noise reduction technology or is quieter than this one, I’ll mention a few names below to help you make a decision quickly. Let’s find out how good this model is as compared to its competitors.

Quieter Models

  • Westinghouse’s WH1000i produces an average sound of 59 dB at half load.
  • WEN 56203i 2000-Watt Portable Inverter measures only 51 dB at 25% load.
  • Westinghouse iGen2200 goes as low as 52 dB with a double-insulated acoustic enclosure and a low tone muffler.
  • EcoFlow Delta 1300 produces a sound level of only 42 dB at 25% load.
  • Champion Power – Model 100574 has an output of 64 dB while running at full load.
  • Honda EU2200i can run as low as 48 dB at 25% load. 

Louder Models

  • Briggs & Stratton P2200 has a noise level of 59-60 dB at ¼ load, which is pretty loud.
  • Westinghouse iGen1200 produces sounds measuring 58 dB at a quarter load cap.

To conclude this discussion on the sound level, A-iPower has still a lot to improve if they have to make this model more user-friendly in terms of noise pollution. But, at this price, it’d be very difficult for you to find an inverter which is this quiet.

Hence, I’d give a pass on this feature of SUA2000i.


Now I’m going to review one of the most sought-after features of portable generators, for this model. Portability is of utmost importance as portable generators are supposed to be “portable”. And that does not just mean that they can be moved around, transporting them should be able to be done with ease. 

SUA2000i excels at this feature exceptionally and comfortably beats its competitors with similar outputs. 

Here’s what I found out about this inverter.

Dry Weight

The dry weight of this A-iPower generator unit is 46 lbs. / 21 kg.

Wet Weight

The wet weight or curb weight of this generator is about 56.1 lbs. / 25.5 kg (that includes Engine Oil = 0.4 qt and full gasoline tank = 1.1 gals).


If we compare the dimensions of this inverter with a few other models, it looks amazingly compact. The lightweight design of the generator allows it to be placed in cramped spaces in your RV or at home. 

Its dimensions are:

  • Length: 21 in / 53.34 cm
  • Width: 12.5 in / 31.75 cm
  • Height: 19 in / 48.3 cm


Though lightweight, one of the biggest downsides of this generator model is that it does not come with a wheel kit. But there is a carrying handle right at the top. I guess the overall weight of the engines compensates for the issue of not having wheels because, at 46 lbs, the unit can be carried around with one hand by an adult person.

That said, it would have been much more convenient if A-iPower had also incorporated a set of small wheels in this inverter so that moving it would have been much easier than simply carrying it around.

Portability – Comparison with Other Models

If you are looking for a lighter model in the same price range, I’d suggest that you stop the search immediately. That’s because this inverter is among the lightest in the category at a much lower price.

Here’s how a few similar models fare in dimensions and weight in comparison.

Service and Maintenance

Servicing and maintenance of electric generators is a sensitive job and should always be performed by certified and knowledgeable professionals. It would be best that you call a professional or a technician to help you out in that regard in case you are not familiar with the maintenance procedures.

A-iPower has listed all the important safety instructions and maintenance processes in the operations manual of the model SUA2000i. You can also reach out to their customer support team at 1-855-888-3598 or send an email at [email protected] for further help. 

User and Operation Manual

For the operation and servicing instructions of this model, go through the owner’s manual here.


A new SUA2000i inverter generator has a 2-Year Residential/Commercial warranty period. A-iPower recommends that you perform the required maintenance as per the schedule given in the owner’s manual to avoid any unnecessary damages to the engine. 

Just keep in mind that A-iPower may deny the warranty claims if the inverter or any of its parts has failed due to neglect, abuse, unapproved modifications, or improper maintenance. 

Commonly Known Issues

During my research about this inverter, I have come across a few common issues that the users face in the long run while using this generator. I’ll list them just to give you a heads up if you purchase this model.

Starts With Multiple Pulls

One frequent issue that the users have reported is that the inverter does not start with the first pull. It takes a minimum of 4-5 pulls before it roars to life. 

As there is no electric start, this makes the operation pretty inconvenient for the users.

Pull-Cord Breaks

A very frustrating issue pops up after extended use, and that’s the breakage of the pull-cord. There’s no other way to start the inverter, so you may have to wait for the replacement parts before using it again.

Starts On ‘Run’ Position instead of ‘Start’

The inverter looks pretty well-built and should not present any issues initially. But a few customers complained that the engine does not start when the cord is pulled, and the multi-switch is at the ‘Start’ position. You’ll have to set it at ‘Run’ instead and then pull the cord to start it.

High Noise Level

A-iPower has claimed that this inverter is super quiet. However, that label is not strictly valid as the generator produces a considerable noise level that renders it unfit for use near the windows or at a quiet camping place. It quickly goes beyond 70 dB at full load.

However, if you don’t have any issues with the sound level, this inverter will work just fine for you.

Frequently Asked Questions

Let’s go through a few common queries of the potential customers who want to know more about a few features of this generator.

Does Yamaha manufacture the generator parts of this inverter?

As I have mentioned in the review above, the 79 cc engine has been manufactured by Senci. Yamaha does not manufacture any parts of this inverter. 
However, the engine used in this generator is a clone of the Yamaha MZ80 engine. While not being inferior in any way, Senci is a way more cost-effective product than Yamaha. So there are no downsides here; you do not have to worry about the sub-standard quality.

Is this generator set waterproof?

It is a closed frame inverter. The casing looks pretty solid and compact. However, there is no mention of the case being waterproof anywhere in the manual or on the official website. So I’d suggest that you keep it covered or indoors under a shed to save it from extreme weather effects and water damage.

What kind of fuel can I use? Is there any natural gas conversion kit available?

This model uses regular unleaded gasoline as fuel. There is no option to use any other kind of fuel like natural gas or propane unless you use a conversion kit (that too at your own risk). 
A-iPower recommends that you use fresh, clean gasoline with a minimum octane number of 85. Make sure to use only unleaded fuel. Using leaded gasoline will severely damage the internal parts of the engine. 

What is the fuel consumption rate of this inverter generator?

The engine runs for about 7 hours at 50% load on a full fuel tank of 1.1 gallons.
If you want to know more, I have also mentioned the estimated run time for 25% and 100% load in the above review. 

Is there any extended fuel system for this unit? Can I connect it to my RV’s fuel supply to keep it running for as long as I like?

All I can say here is that this generator has not been designed for a constant fuel feed, and trying to enable it for any such thing may result in tempering with the parts and voiding your warranty.
Just keep refueling the fuel tank for as long as you require the power.

What type of engine oil should I use for this generator?

A-iPower has recommended some engine oil types that I’ll mention here.
* YAMALUBE 4 (10W-40), SAE 10W-30 or 10W-40
* SAE #30
* SAE #10W
The recommended engine oil grade is API Service SE type or higher.

Does this inverter come with an hour meter? 

There is no hour meter included in the generator kit. There’s no digital display to show the running time either. For logging the total number of hours, I’d suggest that you use a third-party hour meter.

What is the THD of the output?

A-iPower claims that this generator produces ‘clean power. The company hasn’t explicitly mentioned how clean it is. 
Neither the manual nor the official website mentions the exact total harmonic distortion of the output. 

Does the generator include a parallel kit?

The parallel connection capability of SUA2000i allows it to link to another generator to double the output. The generator set comes with a set of parallel cables.
As I have mentioned in the review above, you won’t be needing any external parallel kits; the feature is already integrated to allow the convenience of operations. 

Pros and Cons

A-iPower has mostly focused on making a generator at a low price while maintaining ample quality. Due to this reason, the company has skipped a few features that are mostly present in high-end inverters with the same output.

Let’s go through the benefits and disadvantages of this inverter model.


  • Approval certifications. EPA III and CARB Compliant
  • Compact size. Extremely lightweight (46 lbs. only)
  • 7 hours run time at 50% load. Increase in fuel efficiency with the ’Low Idle Mode’
  • Low oil shutdown protects the engine from damage
  • Built-in parallel kits. Parallel cables are also included with the generator set
  • Low noise function. Only 58 dB at 50% load
  • Portable design with ergonomic handle. Move it around with one hand


  • No pre-installed hour meter. You’ll have to buy it separately from another vendor
  • Pretty loud at full power. Exceeds 70 dB noise level
  • Does not include a remote start technology. Pull start every time
  • The fuel tank is small. A bigger fuel tank would have been much more convenient


It so happens at times that a budget-friendly yet convenient and quality solution is needed. That’s where A-iPower comes into play. This model is among the most cost-effective inverters you’ll ever find in the market. And for such a low price, it still holds more than a handful of impressive features that will help bring more convenience to its usage and operation for you. 

The portability of the A-iPower SUA2000i allows you to move it around with ease with just one hand only. After all, it only weighs a meager 46 lbs, a weight an adult can easily handle. The low idle mode, built-in parallel kit with cables, low oil shut down, and extended run-time are stand-out features. Want to compare it with the best in business, Honda? Well, Honda inverters with the same specs are about four times the price of this generator. See why this model is a good value for money? You guessed it right because of a plethora of features at a meager price.

This generator model is ideal for outdoor events such as concerts, camping trips, tailgating parties, etc. If you plan to connect it to your RV and other powerful applications, you may want to connect another in parallel first. This will ensure that you are getting the output that you need.

A-iPower equipment portrays quality on a budget. And this inverter reflects the same. If you do not want to splash too much cash on fancier models while also having your job done, A-iPower SUA2000i is the right choice for you.
