A-iPower SUA4000iED

Should You Buy It?

There are few dual fuel inverter generators on the market. The SUA4000iED is one of them though it comes at a fairly hefty price. It is simar to the slightly less expensive SUA4000i but has more of the features buyers may be looking for. In addition to dual fuel, it also has an electric start with a remote capability and a more comprehensive information display.

There are some mixed reviews by those who have bought this model, so it's good advice for you to make the purchase from a reliable seller to whom you can return the unit in case of problems soon after receipt.

Remember that all kinds of generating equipment can be affected by altitude which reduce their performance the higher you go and therefore may not reflect the power output advertised.

Overview of the Generator 

A-iPower SUA4000iED Front and Back

This dual fuel inverter provides clean, relatively quiet and light, and economical power for many types of recreational use including camping and tailgating, but also is a capable unit to power some items in your home during a power outage. It's RV-Ready, meaning there is no need to buy an adapter in order to connect the generator with your RV as an adapter is included. It also has some other useful accessories in the box.

Dual fuel generators are popular owing to the versatility they offer. This model can provide you with a reasonable amount of power whether you're using gas or propane. It's also fairly quiet to operate with a 58-68-decibel noise rating under various loads.

If you don't need dual fuel or an electric start, then the SUA4000i may be a better option as it comes in a bit cheaper.

Controls and Features

A-iPower SUA4000iED Control Panel

It's quite a busy control panel that offers you a whole host of features with the electric start at the forefront. Among its other features are an ability to switch fuels on the fly, and a data center with information on voltage, hours, frequency, power, and fuel. Like the SUA4000i, it has a low idle switch, parallel connectors, 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, 1x120v 30A, L5-30R 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 and 1-year for commercial use.

Power Output

The SUA4000iED has a 223cc OHV 4-Stroke engine with a starting output of 4000 watts and a running output of 3500 watts using gasoline. There is a bit less power available with LPG (3500 watts starting and 3200 running). To conserve fuel and offer quieter operation the model has a low idle switch.

As an inverter, the A-iPower's power output is clean and free from fluctuations so you can safely connect sensitive electronic equipment.

The generator can be connected in parallel with another SUA4000iED. A-iPower provide you in the box with the necessary cables.

What Most Buyers Like

First and foremost is the electric start with the addition of a remote capability which allows owners to shut the unit down, for example, from inside their RV. Some buyers find the SUA4000iED quite a good buy when compared with the Honda equivalent. And being able to run the model with LPG means less of a problem with stale gas and complications with storing gas.

What Some Buyers Like Less

Customer service has not always been the best. The battery supplied with the unit is cheap and nasty. Several found that starting the generator was difficult when using the recoil pull mechanism. Parts are difficult to come by when problems do occur.
