Asked by Buyer67 December 12, 2020

Thank you for taking the time to let us know! It is correctly listed as a floating neutral generator, but we are updating our manual to reflect the correct grounding.

purchased this for travel trailer. I am having trouble with the unit overloading when engaging my...

Asked by Brian September 8, 2020

<p>Hi Brian,</p> <p> There are a few things you can try to help your generator operate optimally in high temperatures. First, we recommend utilizing a higher viscosity oil in extreme heat. Second, building a well ventilated shelter that keeps your generator out of direct sun can help. Finally, performing more frequent periodic maintenance is necessary under any severe conditions, including very high temperatures. Hope this helps! </p>

does it have a spark arrestor?

Asked by mtnman65 August 6, 2020

Yes, the iGen4200 has a spark arrestor.

how long can I run this without rest? (It states 18 hours run in full tank but can I run it straight 18 hours nonstop?)

Asked by LGVale July 31, 2020

The iGen4200 will be able to run continuously provided that you are following proper care and maintenance of all generator components listed in your User Manual. Changing the oil, air filter, etc. will be able to keep your generator running longer with optimal performance.

can I get all 3500 watts out of 1x120v outlet? or out of both 2x110v outlets? or is it required to use the 30A to get all pow

Asked by Comanch3 June 8, 2020

volts times amps equals Watts. If you have a 30 amp breaker and outlet, it's 30 amps x 120 volt for a maximum of 3600 Watts on that circuit. The unit has one 30 amp outlet and one 20 amp outlet. If you go over 30 amps on the 30 amp circuit it will trip the breaker.If you go over 2400 watts on the 20 amp outlet (20 amps x 120 Volts) you'll throw that breaker. The generator has 4200 W surge and 3500 W running maximums. You can not exceed these at any time either with one 30 amp outlet or both.

what is the part number for the wheel kit and where to purchase?

Asked by BBB June 7, 2020

We do not currently offer a wheel kit for the iGen4200.

When this igen4200 is at full load, is to as loud as the 3600 generator since they are both the s...

Asked by Wantinfo1 October 12, 2019

It is somewhat louder under full load but quieter than a non inverter generator. With no load I spoke with my wife on the phone and had no difficulty hearing when 10' away from the unit. She could not hear it until I told it was on. At full load the engine throttles up and probably doubles the DB of that at idle. If quiet is a major concern I would opt for the enclosed version however.

Does this generator take gas and propane?

Asked by joel September 16, 2019


Why is the quality and value rating so low?

Asked by Jule September 7, 2019

This should’ve had plenty of power to run everything but couldn’t handle it.

Can you connect this to a transfer switch?

Asked by Selan September 3, 2019

The iGen4200 is a wonderful generator that is great for RV usage or just for home backup power to individual items. Unfortunately, this generator does not have a Transfer Switch Ready outlet and may not be the most practical usage of total home back up power despite any adapters that may be added.

Small but Mighty!
I bought this generator a month ago, so glad we did, Hurricane season is coming. It’s light enough for both my husband and I to move. And quite enough to talk over. Will run our refrigerator, freezer and a few lights and fans.
by DawnC
Easy setup
People complained about the oil funnel, so I supported mine with some small rope. You have to keep the funnel bent while you spin into the threads on the engine block. She runs smooth and idles up to equal the load.
by DrWright
great features
I bought this generator after a week long power outage. While I havn't used it for long period of time, it started up quickly and runs very quietly.
by dfox
Great features
It was easy to install. Very silent. I would recommend it to my friends!
by @Sammy
Great power, low noise level. Love my igen4200
Just got my generator a few weeks back and already paid off with storm passing and leaving us without power for 3 days. The generator took care of all my sensible appliances( large TV, satellite box, console, monitor for console, laptops and phones etc) also handling my fridge and lights through the house without a hitch..i love how easy it starts up even my wife was able to turn it on at first pull. Comes with all you need at first minus the gas... ran around 40 hours total with around 7 gallons of gas... the manual states first oil change at 20 hours but unit will warn at 25 hours.. still did it at 20 ... very easy to do ... if you need a backup power source this is a great choice. Did several noise testing and generator being around 20 feet away from my room the noise my fan makes while running the generator basically made the generator noise to be nonexistent.
Runs great
1 pull start out of the box. Runs great. Powers inside appliances and cell phones
by Ehen

Appears to work
The packaging was extremely worn and it appeared to have been previously opened. After unboxing the generator, I notice there was a significant dent in the frame (picture attached). Notwithstanding, I started the generator effortlessly and tested it for further defects. Suffice to say, it ran as described. However, I still remain apprehensive about the reliability of the product, considering it was delivered with noticeable damage to the frame.
