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.

Recommended by a family member and they were spot on. We bought two, use for camping and love them! Was concerned when the recall occurred. However all fears were erased by the efficient, professional manner exhibited by the Westinghouse people I talked to and the quick repair. This is a wonderful generator. BG

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.

I purchased this generator to run a sump pump and some lights when the power goes out. After shopping around, I don't think you can beat this unit for the price. It has more output than anything else in its class. The controls are very easy to understand and the manual is spot-on with details on maintaining this gem.

I reviewed and studied "every" portable lower wattage generator/inverter sold in the US! And on paper, features, capabilities, price and, of course, as always comparing to Honda 2000 and Yahama 2000, the Westinghouse Igen2500 scored the best! On price it beats almost everybody, but I would have paid the same as the "BIG2". Why?...........the running wattage is 2200....I need 1800....that means I will almost always (except on surges) be running well below max saving fuel with less NOISE! I am one of those oldies that appreciates and welcomes technology that actually works for you! The diagnostics display is digitally fantastic.......watts, fuel time to run, fuel level, and volts (sadly missing amps) right there all the time (checked them against interactive power meter). Only one offers similar and some dabble alittle., but not the BIG2 at all. 98cc keeps fuel and noise level down and under 50 lbs just like the BIG2. Since noise levels are mostly subjective even when measuring with DB meter, it seems to be mostly a tie with the edge going to BIG2 according to tests run on Youtube not the manufacturers. That's why I built a 2- sided roofed baffle box to steer the noise away. All the controls are upfront and fully visable like on all the better units. All the internals....oil, gas drain, air filter and spark plug are very accessible and visable....check any of the competition for this convenience! Offering a 3 yr warranty and lifetime tech support is above average than most, though I am hoping I'll never find out if either are any good! Do your homework and pick one that's best for you! jimg

Lost power after a tree limb ripped the power lines off our house. Normally wouldn't be a problem except the spring thaw and rain from the previous day was flowing in my basement, so I needed the sump pumps running. Picked up the igen2550 once the store was open, had it running within minutes and saved us from a flooded basement.

I own a larger inverter generator, and I'd like it so much. I decided to buy a second one that is more portable for camping, road trips, or working on my land. My off grid cabin has no access to electricity unless I use a generator or solar panel, so this is what I have powering my tiny home.

This iGen2550 inverter generator is awesome! Couldn't believe how quiet it runs. Add a 15 Amp load and you can barely hear any increase in speed/sound. Easy to start. Great digital indicators. Easily runs my table saw, miter saw, or other tools (one at a time). Love it.

Even though I have only used the generator a short time it is performing very well. Setup was easy and it starts with two pulls, runs strong, and handles the tool loads well. I love the ECO mode as noise is much less than my other generators. Data display is great for checking operation and hour meter is nice for keeping the maintenance schedule. Its better than I expected and count on it lasting a long time.

I bought this generator primarily to recharge my electric battery generators. It is more than adequate to recharge both of them with additional power to spare. The instructions provided were clear to understand. It is easy to fill and check the oil level. Changing the oil in the future should easy and clean. I connected my unit to Propane, and it started up on the first pull, which surprised me! Subsequent startups were just as easy. I plan to use only Propane so I don't have to drain the carburetor bowl for storage. It's nice to have the option to use gas though. On start up, I checked out the Eco feature and it idled at a lower speed as it should. The first load I put on it was an electric heater and it handled that well. It drew about 1500 W. The noise level seems moderate. It actually sounds quieter than the video provided. Well, I'm very happy with this inverter generator and will possibly buy another.
