Generac Generators

Generac dominates home standby — the permanently installed units that run off natural gas or propane and start themselves when the power drops. Those are not Amazon purchases; they need a licensed install and a transfer switch. Their portable range is the part you can actually buy online, and it is a smaller share of what they make.

Not sure which of these is big enough?

List what you need running at once and the tool works out your real peak — total running load plus the single largest startup surge, which is a much smaller number than adding every surge together.
