Portable Power Station

Portable, versatile power station. I'm trying to locate a portable power device that could run more than one of any number of devices.

The things running might include a portable A/C unit for cooling a tent or something small, a freezer, an Instant Pot, toaster oven, etc.

I would like something quiet, but powerful and am not sure what to get.

I located this gasoline-powered generator on Amazon.

Suggestions are greatly appreciated.
