I bought this Champion model 100520 to use as an emergency backup generator for my house during outages.  I made the decision based on my previous experience with Champion products, as well as the fact it was one of the largest and yet most reasonable priced inverter generator out there.  This will run my 220v 20 amp well pump along with just about anything else in the house I want it to.  I also have a backup 19cu ft freezer and lots of electronics that this unit can safely run.  So far, I'm very happy with the generator and it is at least 25% quieter than other open frame models.  I made this review to try and help others so I hope you find it helpful.  Let me know if you have any questions - thanks.
