I would like to know how long you had run this portable generator and on what appliances. I had Westinghouse WGen5500 Portable Generator, for over a year now. it has 5500 Running Watts and 6850 Peak Watts. moreover Up to 15 Hours of Run Time on a 6. 6 Gallon Fuel Tank with Fuel Gauge. WGen5500 Portable Generator is the best generator for small house and can run up to all most all appliances in the long run.
