Which is better for running a refrigerator during an outage?

Both can do it. The Jackery runs a fridge quietly indoors for hours on its 3,584Wh battery. The Generac runs it far longer on a tank of gas but must sit outside.

Can I use the Jackery indoors?

Yes. It has no exhaust and makes no fumes, so it can run in a garage or living area. The Generac must stay outdoors because of carbon monoxide.

Is the Jackery worth the extra $680?

If you need indoor, silent power or want to add solar and batteries over time, yes. If you mainly need raw watts for tools or a well pump, the Generac gives more power for less money.

The Jackery's LiFePO₄ cells are rated for 6,000 cycles to 70%+ capacity, roughly 10+ years. The Generac's engine can last many years but needs regular oil and fuel maintenance.

Which handles a well pump or central AC?

The Generac. Its 8,000 running watts and roughly 10,000 surge watts start large motors that the Jackery's 3,600W continuous output cannot.

Can the Jackery run my whole house?

Not on its own. It covers critical loads and expands to 21 kWh with extra batteries, but whole-home backup needs more capacity than one unit.
