The iGen 2500 will power either one of our camper's 15000 BTU air conditioner units just fine. I had to make sure that all of the electrical loads were switched off otherwise it wouldn't start them reliably. I installed an Easy-Start in one of the units and now it'll start it effortlessly, and I don't have to shut the battery charging circuit off before switching the unit on. 2500 watts (2200 continuous) from 48 lbs. Fantastic

I have ran the generator through the initial 20 hr. break in oil change, varying the load every so often. It is quick to respond to loads, even with economy mode on. Seems to be great on fuel! Very quiet at idle and through the first 50% of load, then the sound level increases, which honestly is to be expected when the gen is running 1500+watts. Very easy to start. One of the best features is the operator control panel; it gives you all important information right at a glance. Overall, very happy with my purchase!

I bought the generator to use with my RV camper and it arrived just in time for a March 2 Nor'easter in PA where I lost house power for 2 days. After adding oil and gas, it started on first pull. It is quiet at 25% load or less but much more noticeable above that. I have no previous experience with other inverter generators to compare noise levels though. I ran it 20 hours and changed oil. Oil was moderately dirty, nothing I took exception to. Added Mobil 1 oil and ran another 8 hours with no issue. So far I'm happy with my purchase.

LOVE IT...LOVE IT... LOVE IT!!! We purchased a new 5th wheel a year ago and had one chance to use the iGen2500 before the end of the season here in MI. It worked flawlessly! I bought two of these as we have 2 A/C units and although good for a single 15K unit, two is just too much for it. I intend on connecting them in parallel for a whopping 5K watts of juice! Gotta love it!!!

Bought this iGen2500 because it is only 46 lbs and is rated somewhere at 53/59dB. My old generator is 98lbs and about 70dB. It starts easy and is pretty quiet, although any load at all will cause it to increase RPM and noise level. Noticeably louder than my friends Honda 1600/2000, but it's more powerful. I'm hoping after I add a starter capacitor to my 13,500 BTU AC unit that it will be able to run that too. We'll see. Would prefer being able to check the oil without having to remove the side panel with a screwdriver (2 screws and 4 holding pins). Also, the digital screen is hard to read during daylight hours, and cycles 4 sets of numbers. It's supposed to show run time (since started?) and total run time (like an hour meter). Can't make any sense out of the numbers that show here, so I've put in a request from Westinghouse for an explanation. Expecting many years of RV use on this unit.

I started out using some 85 octane I had in the garage. The exhaust didn't smell to good and it didn't run very well. I always intended on running 91 octane Ethanol free gas and when I did it ran much better and the exhaust didn't stink like old gas. She likes 91 so that's what I recommend you run.

My one problem is that the engine control switch is backwards. I have to turn the switch to "off" to start it up and turn the switch to "choke" to shut it down. It runs quietly which is nice. Looking forward to powering up some tools out in the country.

Received the iGen2500 about a week ago. Setup instructions were clear and simple and took about 5 minutes. Started up first pull. Very quiet, particularly in the Efficiency Mode which drops the idle down to deliver only the power that is needed. I learned quickly that to power high demand equipment, like a compressor, it is best to take it out of Efficiency mode to start it, which makes sense as the surge current takes a few seconds for the generator to ramp up to speed. Otherwise, all my tests of power delivery, volume, etc. are great! Time will tell on longevity.

I purchased this product after some internet research on generators. The reviews told me this was a great product, the generator was easy to start and use, and the running noise levels were better than the Honda or Yamaha. I started the generator and plugged several power tools into it and it performed as expected.

Hard to start at first then immediately went to an over speed situation and indicator showed over load situation. Unable to contact service on 7/3 and when contacted them 7/5 there was NO sense of helping a traveling customer get a replacement shipped soon enough to catch up with us.
