  1. Happy!

    Recently went on an elk hunt here in New Mexico. Camped at about 9000 feet. Generator started up flawlessly everytime. The remote works from very far away, even when there are a couple campers in between. Could barely hear it when inside my camper and it was about 20 feet away. Very happy so far. I do wish it had a drain plug for changing the oil. It must be tipped to drain out the fill hole.

    Best overall generator in this category. Easily best value for money as well.
    * Relatively quiet. I feel like under full load it may be somewhat louder than the Honda but it is close and certainly not a "loud" generator
    * The 30A receptacle is installed in the correct orientation. This was reported to be an issue in early releases of this generator.
    * THEY ADDED AN ENGINE LIFETIME HOUR METER. I don't recall my previous one having this but it's definitely a nice enhancement.
    * It's _just_ light enough for me to lift into the very high bed of my Chevy 2500HD. Even when carrying a full load of fuel I can still lift the generator without help.

    I will have to admit I was very skeptical about the reviews that the Westinghouse IGEN 4500 was getting. I watched numerous video reviews. Read reviews and decided to bite the bullet. BEST decision I've made in a while. This generator is so quiet. You can actually stand beside it and carry on a conversation while it is running at almost max load. I tried it. I tried maxing out this generator and seeing how loud it would get. Still so quiet. Now the power is outstanding also. I had the Electric water heater, 15k btu a/c, tv, and water pump running all at the same time, for a 75% load. my old regular generator wouldnt run half that together.
    If your on the fence about buying a new generator, you better buy this Westinghouse IGEN4500. The price, power output, and sound/quietness, are second to none. The price is great also.
    So if I had to do this again, I would have bought this years ago!!

    I did a lot of research before purchasing my igen4500. Why anyone would buy a Honda is beyond me. More than twice as much for 20% less power. This generator is the best value out there. Active RV'er so we use this generator a lot. No issues at all very quiet to boot. Great service and quick shipping as well.

    You will not find a better value for a 4500 watt inverter generator than the igen 4500. Honda costs almost twice as much. My gen starts right up on every camping trip and is no louder than my friends Honda. I could buy 2 for the price he paid for his Honda.

    Ordered in Monday received it on Wednesday at noon. Put the oil in, filled with gas, attached battery plug. Hit the start button, started and run in about two revolutions.
    Mounted it on the back of my camper, where the failed Honda was. Runs air and microwave. Without a problem. So far I'm really pleased with the product and this company.

    This generator started right up using the electric start feature. No hesitation or anything. We connected it to our camper and quickly learned there was a sequence one has to follow to make sure it doesn't trip into overload, but now that we know that, it works perfect! Nice and quiet, too, even with an RV A/C load on it.

  10. A great portable generator.

    Out of the box it is a great unit.
    I thought it was strange that coming straight from westinghouse you have to take it apart to plug in a couple of connectors.I called westinghouse when I got the unit because it wouldn't start. They said their was a service bulliten about this. I went online to see what was needed and took care of it. Paying $949.00 for the generator and having to take it apart first to get it to start is nuts. Why didn't they connect these plugs at the factory? Why ship out a unit that isn't ready?

    I have just received my igen4500 about 5 days ago 6/3/18. Apparently westinghouse has updated the front panel on the model to now include a battery switch, however the tt30r is still upside down which is puzzling. The generator was somewhat damaged on shipping. Careless shipping to be blamed I'm sure. However, it runs amazing. On first start up I thought it was in eco mode it was so quiet when actually it was off. Then I turned it on and it seemed quieter than my igen2500. The battery comes pre charged and the float charger that comes with it is convenient. Overall it's a 5 star product but due to the tt30r still being upside down and shipping damage its 4 stars for my review.

  14. Great Generator with Lots of Power and Features!!

    This unit has all the bells and whistles. Electric start and remote start. A really neat panel with futuristic gauges. Started well and ran for a short time. Only complaint so far is the RV plug is upside down and there is no manual choke. However, the auto choke is working perfect at the moment. Very quiet and smooth operation.
