I get that.
First the fairly civilised people seeking charity will be at your door. “You seem prepared, can’t you help us? Our 4 year old twins are starving and haven’t had food for two days. Can’t you spare anything?” and 10 more families like that. and 20 more. you get the idea.
Next come those who aren’t as benevolent, will scout you out and threaten you, but can be scared off to threaten a softer target..
Next come those who come in larger modestly organised squads. And frankly they will kill you as soon as look at you. They want what you have, and the sound of your generator was the honey.
I am just saying that *IF* you can properly organize and defend your neighborhood, then your generator is your friend. Just be realistic about how fast and how far civilisation will dissolve. Nine days. You have nine days.

FWIW, Kevlar vests are on my list of SHTF items.
