Paid for itself in 1 week

I purchased this item a few weeks ago. I live inside a national forest where it winds and rains often blowing branches onto power lines causing power loss for many hours at a time. This occurs about 30 times a year, shortest downtime being an hour and longest being 6 days. Last week I lost power twice for about 12 hours each time and this unit kept my kitchen area and frig running perfectly, saving about $600 worth of frozen/cooled items, twice, hence $1,200 saved by a unit that cost less than that just in 2 weeks! Easy to connect and very quiet to run.

Started right up.

I ordered this generator last week. It was delivered upside down. I immediately unboxed and went through the start up process and it started on first try. I have not had an opportunity to run with anything connected but it was quieter than expected and I am Satisfied with my purchase.

great first impressions

I just opened my igen4500df and first impressions are impressive. Added the included oil with the funnel provided, installed the battery, hooked up the regulator to a propane tank and it started up and idled instantly! This generator is incredibly quiet, you can easily have a conversation right next to it. I purchased this for running my RV and have not used it to power anything quite yet.

Best dual fuel inverter option

I purchased this about a month ago after researching the field of dual fuel inverter generators I was pleased with the quick start guide and ease of starting and breaking the generator in for use. Westinghouse engineers built an affordable feature packed , quiet, smooth running workhorse!

Good overall

Bought for a backup if power goes out. Rec'd in good condition everything was there. "Read" the directions! Used the electric start started after 2 attempts. Ran at 1/2 load or less as required. Worked good, very quiet. Very fair on fuel. Tried to start with recoil a few times, didn't get it started. Back to elec start, it started right up. Have about 5 hrs on it. Will see if it lasts. Seems well made.

Worth the wait to be back in stock

IMO best quietest 30 AMP RV ready Generator INVERTER. Almost bought back in April for $800, then went out of stock everywhere and have been watching. Now August and Walmart site said would ship in 2 days, which it did, and a few days after that when it arrived, they were out of stock again. Must be hundreds of other people wanting this, too. BE careful when searching, because the gas only version will pop up at a better price, SO BE CAREFULL if you want the DF (dual fuel) version. When I received, I opened the gas cover and this new unit had previously had gas in the tank. The oil fill hole showed that it had oil in it previously, as well. Careful inspection showed no other possible trace of previous use. I hope the factory is testing before shipping AND if they are they should advertise benefit. Otherwise, I fear that I received a re-furbished/repaired unit. I ran on propane only so far for 3 hours in eco mode, then 4 hours under light load plugged into camper with AC running. It showed a "U" 1.34 load but have not read up on what that means, yet. Regardless, light load AC plus TV and the Dish Hopper 3, some 10 LED lights. Have now changed oil to a Mobile 1 full synthetic Next change at around 50 hours or one year per instructions. SO HOW LOUD IS IT? THIS SENTENCE IS LOUDER than this unit in eco mode no load. about 25% load, my guess, it might be up from base 52 decibel to maybe 62 decibel (i used my ears only to guess this 10% or double sound level). Under load, you do know it is there and maybe some RV neighbors will know it too, but it is not your parents generator that sounds like a car without a muffler. I recommend this and would buy again if needed the 50 AMP you get when plugging two of these together.

Works Great / Oil In Shipping Box When Opening

Generator works as advertised, however when I open the box there was oil in the bag it was shipped in. There was motor oil on the bottom of the box and motor oil leaking out of the bottom of the unit. I sent information to Westinghouse support and they answered quickly and told me that this is normal.

Incredibly Quiet

It took quite awhile to find one, but eventually I was able to get it. Its our first generator and so far I couldn't be happier. We haven't put it to the test, but I did test it with an angle grinder and it worked flawlessly. Very quiet, which is important as I don't want to broadcast when I have it running to everyone. Very pleased.

Great so far

I was concerned about some shipping damage to the cardboard carton. Upon opening the box there was no discernible damage, so I finished unpacking, plugged in the battery, added included oil, and hooked up the propane regulator. It started with a touch of a button. I've since tried multiple loads, including a 1hp compressor, 1200 watt heat gun and numerous saws. So far everything has worked beautifully. I've also been running it for the last 7 hrs on gasoline. I've started it with the key fob, and the pull starter, everything has been as hoped for. Very pleased on this first day.

quiet- starts easy

I looked at the remote start. I wanted something quiet also a generator which was lite weight.'' about 98 lbs''. I ran generator for a short time. Started several times just to play. No problem. I got it for my RV to camp off the grid. I will have a better idea of how it works at the end of summer of 2022. I do like the manual that came with it. It covers a lot of info. I liked that. I like the control panel.
