What size generator to run an instant pot / slow cooker?
Instant Pot / slow cooker sizing at a glance: it draws 1000 running watts.
| Spec | Value |
|---|---|
| Running watts | 1000W |
| Starting (surge) watts | 1000W |
| Recommended class (this load + margin) | 1500W |
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.
