This is top of the line! It can be used for RVs and tailgating, but its primary purpose is for home use during power outages. It was bought in 2019 and has been used for about 30 hours. It generates 120 Volts at 60 Hz and has 20 and 30 amp outputs. Its maximum output is 3,000 watts with a rated output of 2,800 watts. Enough to run a small window a/c, a refrigerator, lights, microwave and coffee pot (not all at the same time.) Being an inverter make it safe for TVs and computers.
