I bought this several years ago, used it 3x and works great for lights and such, does not charge up my UPS's, something to do with the sine wave form. Works great so far.

You are correct regarding sine wave — it's due to harmonic distortion. Generators produce "dirty" power that is unsuitable for sensitive electronics. The harrowing reality is that most the new "high-tech" refrigerators will not run on standard generators due to the harmonic distortion. As the wave of the future crests over the next 5-10 years, we'll all be needing inverter generators to provide "clean" power for our stuff. Much more expensive, but quieter and more efficient. Example from Costco:

Inverter type generators will not work they also do not provide a true sine wave. They produce a modified square wave and most new sensitive electrical items don't like it.

Both the Yamaha EF2000is and Honda EU2000i are listed as pure sine generators. I own 2 of the Yahama units and have no issue powering sensitive electronics with them.

Good generator...I run only LPG. have used it for power outages, runs my fridge, freeze and other internet. Also used with RV dry camping. It is loud.
