Product dimensions

I am interested in this generator but it would have to fit in a specific space. Is the a diagram that shows specific dimensions? I really am most interested to k ow of the 30.5L dimensions includes the folding handle. And is so, how long is the body of the generator without the handle?

Quiet operation

Bought couple weeks ago. Just started last night ran last night for five hours for the break in period. Ran with out a hitch. Used a small griddle plate to vary the load while testing. The screw in funnel to add oil was a nice addition. Do read the manual first the quick start guide doesn't talk about the break in period or we have some cool weather here and was thinking about starting out with the synthetic oil which is not recommended during the break in period.

Power and Security

We live out in the country and electricity goes out several times a year, especially when it is very cold and demand is high. This generator runs out heat pump with ease along with all other appliances in the house. I'm very satisfied with this purchase.

Easy Setup

Bought this generator after having three power outages this winter. This is my first generator and I wanted one that would be quiet but have enough power to run refrigerators, water heater, and heat. Setup was easy. Two people can easily lift the generator out of the packaging and move it around for assembly. Tools needed were included which was great since I didn't have a 24mm wrench. Only part that was a challenge was filling the oil. The funnel included looks like it should screw into the oil inlet, but it doesn't. As a result, it's a bit tricky to fill the oil without spilling some of it. Also, the key fob for remote start has a plastic ring around the battery that needs to be removed before it will work. I didn't see anything about this in the instructions. I started it up to test it using propane. Started easily and was pretty quiet.

Absolutely no problems.

I borrowed one of these from a friend to run my house after an ice storm. After the second day of use, I liked it so much I placed an order for myself. Absolutely outstanding performance. Ran my entire house (gas furnace and water heater) and was still able to run the electric dryer if need be. Great Product!

Sturdy and solid

Features I wanted (prioritized in order), which I found on this iGen11000DFc generator: An "inverter" generator (to get THD or Total Harmonic Distortion under 3%) A "Dual Fuel" generator (to run either Propane or Gasoline) An electric start (from a battery) with "recoil" or manual start option Size: Something close to 10,000 watts (or 10KW) to easily handle any one circuit in our home (hot water heater, electric range, electric clothes dryer, etc.) Transfer switch ready (so I can "plug the house into it") Able to deliver 240 Volt circuits (required to be able to "plug the house into it") Bonus feature: The "c" in the model name for Westinghouse indicates it has a carbon monoxide shutoff feature - to shut down if carbon monoxide levels from the exhaust get dangerous around it. Packaging was great. Assembly was easy. Adding oil was made easy with supplied funnel, etc. Started it up yesterday (on propane) - took two tries to get it to start. The second try, it started but ran very rough, misfiring regularly. Let it do that for a minute or two, then shut it off. Started it again and it started right up and ran smooth. I proceeded to test it over the next 80 minutes, hooked it to our home with a 50 amp cord, and tried various circuits in the home including a heat pump, fridge, freezer, computers with monitors, TV, etc. - all worked fine. Ran the house on it for a while. My wife forgot it was on and started the electric dryer even. No issues whatsoever. The generator handled them all just fine and behaved like it was just idling to do it - it never seemed to strain or struggle. I then disconnected it from the house and started it multiple times, different ways, with the key fob, even pulling the cord (which took two pulls to start it). Every time it seemed to work just great! Downside that I saw only after reviewing the manual in detail - it says that it's not good at cold temps with the included oil (cold meaning below 23 degrees F). I want this for winter in Maine. So, I plan to change the oil out to the recommended 5W-30 synthetic oil for cold temps sometime after the burn in period - but the manual says to use the included oil until the generator is used sufficient to get it through a normal motor burn in of about 5 hours (as I understand it from reviewing the manual). Would I recommend - "yes". Bonus - it was quieter than I expected it to be. That's why my wife forgot it was even running and started the dryer in our home - she didn't even notice it was still on from inside our well-insulated home.

Starts right up

Very happy with this generator, love how easy it is to move around, (I'm 6'2, 230lbs 54yo). Easy to set up and started right up, even with the pullcord. I had to use the pullcord because the battery died quickly; I cant be sure if I somehow left the power button on or if the battery is too small and does not hold up in the winter. For this reason, I purchased a small jumper box to keep inside the home where its warm, to give me peace of mind. But I would purchase again.

iGen11000DFc

I purchased this generator days before the snow/freezing rain event of January 5 2025. I set it up and connected it to a propane tank, after filling it with the oil provided. Starting the generator was effortless with the electric start and with the remote control fob provided. I connected a portable space heater for load while running. This generator runs smoother and quieter than other smaller generators. It's hard to believe how quiet it is. At this time of writing this review the snow storm wasn't as bad as expected so there wasn't a need for its use.

First Time Generator Owner

After several days of researching for a generator, I landed on this beast. I'm sure I don't need this much power but I prefer to have more then less. Generator was easy to setup and even though its pretty heavy, having the arm to pickup up and wheel around makes it easy to move around.
