I’ve only used this iGen4500 once and it ran my AC with no problems. It only ramped up during start-up and then quieted back down. This was at 4500’. We’ll see how it does at 9000’ in a couple of weeks. I’d give it 5 stars if not for the pathetic way you have to drain the oil.

Received this generator as a gift during Hurricane Helene. We were without power for eleven days. I powered only what was necessary: refrigerator, radio, lamp and coffee maker. I rested the generator during the night for 6 hours. On approximately 3 1/2 gallons of fuel and economy setting, I could go for nearly 20 hours of run time. Wonderfully quiet unit. Never missed a beat.

The iGen5000c generator was purchased following a massive windstorm that left us without power for nearly three days. It arrived well packaged, and setup was easy. Instructions were clear and once the battery was connected, oil and fuel added, it ran smoothly from the start. I have yet to put much of a load on it but so far, I am quite pleased with the IGen5000c.

I bought this to use as both a track and home generator (for a few necessary things when power goes out) and figured 4500 max watts would be sufficient. Unboxing was easy and it was nice that it included a funnel and oil. It was easy to start but my main gripes are that the idle is inconsistent (it surges almost constantly, even with there is no load and nothing plugged in), the display doesn't always show an accurate figure (sometimes shows 0 load/output but items are plugged in and running), and it doesn't seem to be able to handle startup of many things that it should be able to (~1500 watt startup overloads the generator).

IGen4500 - Unpacked unit, everything looked great! Very well packed. Filled with oil and fresh gasoline. Before I could even try to start unit, I could smell a strong gas order. After further inspection I noticed gas dripping from bottom of unit. I had to remove covers in order to fine leak, where I found the short 90 degree gas hose between gas tank and line filter steadily dripping. Removed gas line and plugged tank outlet so the 3 gallons of fuel wouldn’t completely run out all over my concrete driveway. What a mess! I’ll try to follow-up on this review after I replace hose and get it running. Hopefully I can change my rating to a 5.

Was a little concerned about the size of it when it was delivered, but it's protected very well in its box. Instructions are great, easy set-up and started up right away using the supplied battery. Fit and finish is nice and it runs smooth and quiet for the size (iGen4500). So far very happy.

Haven't really had a chance to use it to its fullest extent, do I can only rate it based on ease of simple use. Pretty simple to operate. Make sure to read the instructions first to be sure the oil level is correct before starting, but be careful when adding the "initial oil". Although the manual states several times that the product is shipped without oil in it, mine did have oil in it when it arrived. I didn't realize this so, when I followed the instructions in the manual telling my had to add the initial oil or risk permanently damaging the engine, the now excess oil I added dripped all over the ground. So, my advice, make sure the dipstick is dry indicating that there is no oil in the engine. If not, maybe add a little to see if it seeps out before adding the whole bottle.

Does everything a generator should do, but quieter, easier, and with more versatility. Especially liking the ease of an electric start, onboard USB charging, and its ability to throttle-down for low-load ultra quiet operation and its ability to run electronics directly. All things which are not possible, or more difficult to do via a traditional generator.

We had a week long power outage and our friend let us borrow her Westinghouse generator (the size smaller) and it was a lifesaver. We purchased the iGen4500 and it is easy to move and store in the garage, able to run the heater and light for hours and we're really happy to have this going forward.

I have 8 hours running time on it so far and I love it! The igen4500 is relatively quiet for it's size. I love the fact that it has 3 different ways to start it and especially love the remote start. I look forward to our next camping trip to use it. As like everything else this unit does have some bad reviews but give Westinghouse a chance to make your problems right. The good reviews far out weigh the bad.
