Instant Pot / Pressure Cooker Wattage for Generator Sizing
About the Instant Pot / Pressure Cooker
An electric pressure cooker (Instant Pot or similar) that uses a resistive heating element under a sealed pressure vessel. There is no starting surge. Electric pressure cookers are an excellent generator-powered cooking option because they cook food quickly and efficiently, reducing overall fuel consumption compared to using an electric oven. Most models draw 1000 watts during the heating phase and significantly less once pressure is reached and the heating element cycles to maintain temperature.
Generator Sizing for a Instant Pot / Pressure Cooker
Running a instant pot / pressure cooker by itself requires a generator with at least 1,250 W of capacity (2 kW), which includes a 25% safety margin. However, you rarely run a single appliance on a generator. When combined with other appliances, the instant pot / pressure cooker contributes 1,000 W to the continuous running load.
The instant pot / pressure cooker is a resistive load, meaning it uses a heating element or simple electronic circuit rather than a motor. Resistive loads draw the same wattage from the moment they turn on until they turn off, with no starting surge. This makes them the easiest type of appliance to run on a generator. When calculating your total generator load, the instant pot / pressure cooker adds a flat 1,000 W to your running total with no impact on peak surge calculations. Resistive loads also produce a power factor of 1.0, meaning they use electricity very efficiently with no wasted reactive power.
To determine the total generator size you need, use our interactive calculator to combine the instant pot / pressure cooker with your other appliances. The calculator automatically handles the starting surge calculation and applies the 25% safety margin to give you an accurate recommendation.

Tips for Running a Instant Pot / Pressure Cooker on a Generator
Running a instant pot / pressure cooker on a generator is straightforward since it is a purely resistive load. There are no special starting procedures or surge considerations. Simply ensure your generator's continuous (rated) wattage exceeds 1,000 W plus the wattage of all other appliances running simultaneously.
Since the instant pot / pressure cooker draws a constant 1,000 W whenever it is operating, you can accurately predict generator fuel consumption. At typical generator fuel efficiencies, running the instant pot / pressure cooker continuously adds approximately 0.1 gallons of gasoline per hour to your fuel consumption. If the instant pot / pressure cooker operates intermittently (like a thermostat-controlled heater), the actual fuel impact will be lower.
For sensitive electronic components within the instant pot / pressure cooker, an inverter generator provides the cleanest power output. However, most resistive appliances work fine on conventional generators as well. If you are running the instant pot / pressure cooker along with sensitive electronics like computers, the inverter generator protects all connected devices.

Frequently Asked Questions
How many watts does a instant pot / pressure cooker use?
A instant pot / pressure cooker uses approximately 1000 watts of continuous (running) power during normal operation. As a resistive load with no motor, it has no starting surge above its running wattage.
What size generator do I need to run a instant pot / pressure cooker?
To run a instant pot / pressure cooker by itself, you need a generator rated for at least 1,250 W (2 kW), which includes a 25% safety margin above the running wattage of 1000W. However, most people run additional appliances alongside the instant pot / pressure cooker, so your actual generator needs will be higher. Use our calculator to add your other appliances and get a comprehensive recommendation.
Can I run a instant pot / pressure cooker on an inverter generator?
Yes, a instant pot / pressure cooker runs perfectly well on an inverter generator. As a resistive load with no motor starting surge, it is one of the easiest appliances to power with any generator type. The clean sine wave output of an inverter generator is a bonus for any electronic components.
