Why the startup surge matters

A instant pot / slow cooker is a resistive load, so it has no meaningful startup surge. If you size a generator only for the running watts, it can stall the instant the instant pot / slow cooker switches on. Always size for the surge.

Sizing the whole system

The number above covers the instant pot / slow cooker on its own with a safety margin. In a real outage you'll run other things too — and the right method is your total running load plus the single largest surge among everything, not the sum of every surge.
