I have this one, I converted it to LP and its never had any gasoline
https://www.samsclub.com/p/7000-watt-generator-with-electric-start/prod8010540it's off brand but it has a honda engine
I dont think they make it any longer
and I definitely don't connect it to the entire house through the 220v welder plug in my garage with a suicide cord
but I started with a 1500w HF inverter and a couple golf cart batteries

it will run anything you can plug into the wall
for another 13 bucks you can power it from your car

for 300$ you can have one and a lithium battery. if you can charge it with the 12v car battery charger that you might already have in your garage
