it's a powerhouse!

I purchased the iGen12000TFc, it was very easy to setup and the breaking procedure was effortless. the iGen12000TFc is for whole home backup. after testing it today on propane and gasoline I can say that it works VERY good. it is capable of running my furnace, refrigerator, freezer, most all of my lights, and desktop computer at the same time and it's running at approx. 80%. I wouldn't push it that much normally, but I wanted to test it. it's fantastic!

Nice

So far, so good. Ran on propane once. Very quiet. Provided funnel looked like it should thread to oil fill but was too small. Not a big deal. One of the wheel axels was difficult to tighten. Threads were likely a little gummed up. Again, no big deal.
