Quiet and powerful. I had an older style 4500W generator for years. So heavy and hard to maneuver and noisy as heck. This inverter generator is quality built, innovative design, easily maneuvered and I love the features like usb charging and especially digital screen projected run time on fuel available.

This was purchased as an alternative for home electric use if needed. Was started up after initial purchase, worked great! Was started every few months to ensure it was working properly. Unit ran well on both, propane, and gas. Fuel was ran out completely with each run. Recently, tried starting it, and unit will start on propane, but will not start on gas. Unit has less than 3 hours run time. This last attempt to start was approximately 6 months ago. Was very, very disappointed and did not want to leave a review at that time. This is our first generator purchase and unfortunately, it is a let down. Gas was our primary fuel and propane was to be a backup. Unit sits in shop taking up space. Expected unit to work with no headaches. We paid good money and thought we purchased a good unit. Disappointed!

I bought this generator for its duel fuel capabilities. It came with all you new to run off propane except the propane it’s self. I would not expecting a propane to come with it. So far I have only ran it off propane and I might never run it off gas. With that said it is nice to have another fuel option in an emergency. This product has performed up to my expectations so far. It is new and I can not speak for the reliability of this product yet, maybe I will update this review in a couple of months.

I really like this generator. It’s super quiet, the design is awesome and it’s super easy to transport thanks to it’s handle and the wheels. At first it didn’t start after I put the oil and the gas, so I checked the spark plug that apparently wasn’t connected properly but after that it started right away. The remote is a really nice feature!

I just bought this generator this month and set up was easy. I set it to run with propane gas and it started very easily/ no issues and I was very happy with how quiet it runs. I use it to power a portable A/C unit and it has been great. I have ethanol free gasoline in case I want to use it. Hurricane season is here so it's great to have peace of mind with this generator.

Started on the first try. Electric start is wonderful. Ran for over 5 hours for break-in. Never sputtered. Connected it to my camper during break-in. This generator is SO quiet. I listened to my radio when it was running while I washed my camper. I would definitely recommend this model.

My unit works great! I was a little apprehensive at first when I was considering buying the igen4500df because of some of the reviews about the loose wire/choke issue. I unboxed my unit, put oil in it, and fired it up. I broke it in according to the manual, then connected it to my camper afterwards. I ran various appliances and it never missed a beat. I am completely satisfied with my unit so far.

I finally purchased this inverter after using another brand for the last few years. The last use of those paralleled inverters was a disaster. Frequent issues in 0 degree weather while hunting was frustrating to say the least This was the first use after their "factory" deemed them in tip top condition as I couldn't get them to sync with the parallel cable and had frequent overload issues with nothing hooked to them. I've been waiting for the past year to get my hands on this inverter for our 5th wheel and am very excited to use it. It seemed to be out of stock everywhere I looked over this past year. Finally, I got my hands on it! Three things stick out thus far. First, with all the nice features on this set up I'd love to see an hour meter in order to track maintenance. I'll add one as we put about 250-350 hours on a year between boondocking and my week of hunting. Secondly, I'd like to see some sort of break in procedure in the user manual. I've not seen any and don't see anything specific to this set. Maybe there is none, but I would think there would be a note about that too. Maybe I missed it. I track my maintenance to extend the life of things as long as possible so being able to break this in correctly is important. Third, it is very quiet and I am very happy about that. So far I've added the oil, and run it to confirm there were no shipping issues. And will test it out on the 5th wheel as soon as it's back from service.

Purchased this generator to use with our travel trailer and for emergency power. Adding the oil was a little tricky and easy to overfill, but not a big deal. Having dual fuel operation is going to be great and the remote start/stop feature is genius. Had a little trouble starting on a cold morning at elevation when switched to gas so I hope that is not a reoccurring theme. Swapped it to propane and it fired right up and then ran on gas with no problem. I'm marking as excellent for now and chalking the little nuances up to break in period and learning curve.

I received my iGen4500DF last week to provide backup power to business's network equipment and servers. The low THD, less than 3% satisfies my Server's sensitive UPS power requirements. It appears I'll get close to 20 hours on a tank of gas running a 25-30% load, I haven't yet ran enough propane, but it's very efficient, burning about 1 pound in 1 hour and 15 minutes, again at 25-30% load. The gages a great, and I didn't need to use my test meters to measure the load on the inverter. The fuel gage seems accurate too.
