Review of the A-iPower SUA4000i Portable Inverter Generator

As an inverter this model will give you clean, relatively quiet and light, and economical electrical power for all sorts of recreational use including camping, tailgating, and power outages. It's also RV-Ready which means you won't need to buy an adapter to connect the RV to the generator as one is included in the box. The model also comes with a useful selection of accessories in the box.

It packs a decent amount of punch with its 4,000 watts of starting power and 3,500 watts of running power. And it's pretty quiet to operate with a 65-decibel noise rating.

The SUA4000i won't suit those buyers who need a portable generator with an electric starter. However, A-iPower do produce a very similar model to this one called the SUA4000iED which also has a dual fuel capability of gasoline and LPG.

Despite lacking an electric start, the SUA4000i has a comprehensive and nicely set out control panel as can be seen here. Among its features are a low idle switch, an hour meter to keep track of how long the generator has been running, a grounding nut, circuit breakers, and LEDs for output indication, overload alarm, and check oil alert.

The connections include 1x5-20R Duplex 120v 20A outlet and 1x120v 30A, L5-30R outlet. There are also 1x12v DC 8.3A automotive outlet and a 5v USB 1.5A port.

With CARB Certification the generator can be used in all 50 states.

A-iPower provide a 2-year residential warranty.

The SUA4000i has a 223cc OHV 4-Stroke engine with a starting output of 4000 watts and a running output of 3500 watts. The low idle switch allows the engine speed to lower so you can benefit from a less noisy operation and improved fuel economy.

As an inverter, the A-iPower's power output is clean and free from fluctuations. You won't therefore have any problem connecting electronic equipment containing sensitive components.

The generator can be connected in parallel and A-iPower provide as standard the necessary cables to make the connections.

We have not been able to identify many reviews of the SUA4000i. But that is no reason to believe it is not a good inverter generator. However, the relatively high price is likely to encourage many buyers to look elsewhere.

We suspect the high price will put off many potential buyers.
