Generators have GFCI to protect you from electrocution. They are used in hurricanes, on construction sites and everywhere else. The manufacturer recommends they be outside due to the CO hazard. They necessarily must be able to operate in adverse conditions. I won't argue on Harbor Freight quality, but then again I try not to support forced labor in communist countries. I tend to spend a little more to buy quality and i rarely have to replace tools. Read the reviews and look in the back of contractor trucks. You won't find a lot of Champion or Harbor Freight. I keep mine for emergencies as well so I won't gamble on quality in that arena. Good luck in your quest!
