How Does The A-iPower SUA2000i Perform?

Engine and Power

The A-IPower SUA2000i 2000 is an inverter generator designed with campers and tailgaters in mind. Incorporating the latest technologies, it provides clean energy for your sensitive gadgets and appliances. It is perfect for powering a laptop or charging your phone while you’re on a trip. It is equally capable of powering various kitchen appliances, too, including RV refrigerators, fans, and even a space heater on the colder nights.

While it doesn’t have the biggest engine in the generators world, the 79cc engine from Senci is more than enough for outputting reliable power. In detail, you can expect:

  • 2,000 surge watts, which are sufficient for starting RV appliances, such as refrigerators and portable washing machines, but also a variety of power tools.
  • 1,600 running watts. Typically, that’s more than enough for running an array of electronics at the same time, from laptops to audio systems, power tools, outdoor lights, etc.

A feature we particularly like is the parallel capability of the SUA2000i, which allows you to double the power by simply connecting two generators together. Parallel cables are included in the purchase package and make this choice perfect not only for camping but also for workshops, construction sites, and other heavier-duty or commercial applications. The only thing you should know is that you can only pair it with another identical generator.

Supported Loads

Designed with outdoor events and camping in mind, the A-iPower SUA2000i presents itself as an RV-ready generator eager to serve all your weekend or vacation needs. It doesn’t come with a wealth of outlets – we wouldn’t expect it to come with many outlets either, considering its size – but it has all you need to run a few appliances and devices.

To add up to versatility, the manufacturer didn’t equip it with a TT30-R outlet, which is the standard for the RV, but it comes with a traditional L5-30R twist-and-lock socket and a 30-amp RV adapter. Undeniably, that’s the best you can get, as this configuration gives you the possibility to use the generator for a wider variety of applications.

Besides, you’ll also get another 20-amp outlet as well as a socket for 12V DC batteries. In detail, this power generator has:

  • One NEMA 120-volt AC 20-amp outlet
  • One NEMA 120-volt AC 30-amp L5-30R outlet
  • One 12-volt DC outlet with 8.3-amp adapter plug for batteries or USB adapter for electronics
  • 30-amp RV adapter


Needless to say, there is no use in investing in a generator that’ll die right when you need it the most. Fortunately, the SUA2000i boasts a generous runtime, given the small dimensions of the gasoline tank.

Indeed, this inverter generator comes with a 1.1-gallon fuel tank. Yet, at half-load, it can power your electronics or appliances for 7 hours straight. This is usually enough if you’re mostly using it for day trips.

However, make sure to have some fuel with you for concerts, parties, and other events or trips that could require more runtime. Obviously, the runtime can vary. If you’re using the generator at full capacity, you’ll have under four hours of juice. If you’re only powering a laptop or charging mobile devices, the fuel can last for an entire weekend or more.

Thus, all you have to do is consider your needs to decide whether carrying additional fuel is necessary or not.

Build Quality

The A-iPower SUA2000i is proof that small power generators aren’t flimsy machines. Yes, it has some composite parts, but overall, the build quality is superlative.

This inverter generator boasts a high-quality housing that protects the internal components, including the engine. Cast iron cylinder sleeves provide engine durability and extended lifespan, while the ergonomic construction makes it easy to carry, despite its 46lbs of weight.

A thing that stands out is the easy-start design that offers a hassle-free startup. A multi-switch near the outlets gives you the possibility to turn on or off the engine, fuel, or choke, for simple operation.

The startup is manual, but the ergonomic recoil pull handle makes it very easy to start the engine even on cooler days or nights.

Another highlight is the eco-throttle that provides two engine modes. The high mode maintains high revolutions per minute, making the machine suitable for construction sites and other heavier-duty demands.

The eco-mode, on the other hand, makes it perfect for camping. This mode adjusts the speed of the engine to save fuel and reduce noise.

As you can expect from a last-generation inverter generator, the SUA2000i is CARB and EPA-compliant. You can use it in all states without restrictions.


There is little to say about this generator’s portability. The SUA2000i was built for an on-the-go lifestyle and the outdoorsy type. It doesn’t come with wheels, but at 46 pounds, it’s relatively lightweight and easy to move.

An ergonomic handle molded into the frame makes it easy to carry by an individual. However, the presence of only one central handle makes it harder for two people to carry it, especially due to the inconvenient location of the fuel tank opening.

This isn’t a downside for most people, but elderly users or impaired ones might want to opt for a model with wheels or invest in a cart.

Noise Level

Using a power generator while camping could turn into a daunting task if the machine starts to annoy your campsite neighbors. Luckily, the A-iPower SUA2000i is whisper-quiet. Rated at only 58dB at 21 feet when running at half load, it can easily satisfy your power needs without getting on anyone’s nerves.

The generator gets louder when running at full load, but it’s still bearable. Sure, we don’t recommend running it at full load during the night or quiet time, but during the day, it will unlikely disturb you.

A-iPower’s Brand Reputation

ai-power inverter generators

A-iPower is an American company based in Ontario, California. It offers portable generators, gasoline engines, water pumps, and pressure washers, alongside other cost-effective solutions for power needs since 2011. Their products are generally reliable, and the company enjoys an overall good reputation.

Aftersales Support

While the company has been in business for long and their products are reliable in most cases, the aftersales support is a pain. Support is available via phone or email, from Monday to Friday during normal business hours (8 am – 4.30 pm). However, they are quite hard to reach by phone due to busy lines or lack of an answer.

Customers have complained about the lack of support via email too. Should you have a problem with your generator, arm yourself with patience, as the waiting times are rather long. On a positive note, most people praise the SUA2000i generator for its quality, so chances are you’ll never have to reach out for support in the first place.

Replacement parts are usually readily available on their website or in home and outdoor product stores, so you should be able to find them easily if you need them after the warranty period ends.


The A-iPower SUA2000i might not be the cheapest power generator of its size, but it surely brings outstanding value for money. Somewhere in-between entry-level and high-end options, this generator appeals to casual users who need a reliable machine by their side.

Indeed, considering the number of features crammed into such a small frame, it’s hard to call it expensive.

This inverter generator can keep your sensitive devices running without major risks, it’s quieter than many similar units and relatively lightweight for easier transport. It’s parallel-ready, too, and comes with an RV adapter for seamless powering of your entire recreational vehicle in one easy step.

Customer Reviews

All products we recommend pass through a thorough selection process. Customer reviews are those that most influence our decision-making process, as daily users can spot any advantages and flaws easier.

In short, the SUA2000i enjoys a positive consensus from most users. The unit is described as reliable, easy to operate, quiet, and easy to move.

Among the most appreciated features, we can mention its silent operation and ease of use. Even first-time users have found it intuitive, while the instructions manual has been judged as adequate.

The runtime has also received praise, although some people said that it doesn’t run for long enough. Considering the small capacity of the fuel tank, though, it’s hard to argue that seven hours of runtime are insufficient.

Negatives have also regarded the low wattage output. However, these reviews had no weight in our decision-making. After all, you can’t expect to power an entire household with a small capacity generator, and users know what they get from the start.

A piece of advice, however, is that of calculating your power needs before investing in any power generator. Simply sum up the wattage of all electronics you plan to use at the same time to ensure that the generator you buy meets your needs and prevent disappointment.

The customer support also received a few complaints from the users. Overall, though, people were quite happy with this generator, and the vast majority would recommend it.

A-iPower SUA2000i Pros & Cons


  • Very easy to start and operate as long as you follow the instructions in the user manual.
  • RV-ready generator comes with an RV-adaptor for the twist and lock outlet, while the wattage output is just perfect for camping.
  • Quieter than other similar generators, even when running at full load.
  • Built-in parallel kit and cables included in the package make it super-easy to double the power should you want to. Keep in mind that it can only be used in parallel mode with another identical generator.
  • Three-in-one indicator light serves as an output indicator, overload alert, and low oil alarm.
  • A low idle mode adjusts the engine speed to an optimum level to reduce fuel consumption and noise.
  • The fuel gauge is very easy to read, so you’ll never risk running out of power when you need it the most.


  • The generator is relatively lightweight, but it can only be carried by one individual, which can be inconvenient for some users.
  • While the generator is easy to start, it doesn’t have an electric start button. Choking it could take longer on colder days.
  • The generator has a simple but basic control panel. Apart from an indicator light, it has no data center and no other modern perks.

Final Verdict

The A-iPower SUA2000i is an excellent choice for campers, street food businesses, concert-goers, as well as small workshops or mountain cabins. It is one of the lightest on the market and boasts a simple control panel design that makes it super-easy to operate, even by first-time users.

Despite a small fuel tank, it can run for up to 7 hours when running at half load. For lighter-duty tasks, such as operating a laptop or charging mobile devices, it can provide up to a day or more of runtime.

It doesn’t have any technologically advanced bells and whistles, but it does incorporate inverter technology, so it’s a safe choice for sensitive electronics. It also has parallel-ready capacity, so you can double the power whenever needed.

While it lacks a specific RV outlet, the adapter included makes it RV-ready. You won’t have to struggle too much to power the entire vehicle, just as you would with an RV generator.

Last but not least, this generator is silent and portable. It will unlikely disturb your sleep or annoy your campsite neighbors. Carrying it alone might be a bit of a hassle, but at 46 pounds, it’s still feasible. All in all, the SUA2000i is one of your best bets if you’re looking after a no-frills, easy-to-operate, affordable inverter generator to power your outdoor trips or events.
