Appliance Wattage Chart & Energy Usage Calculator

Whether you’re considering purchasing a generator or home battery backup or just curious about the average power requirements in watts (W) of household appliances, power tools, electronic devices, and more, you’ve come to the right place.

We’ve compiled the average power requirements of hundreds of everyday electronics and grouped them by category below.

Beneath the charts, an Appliance Energy Requirement Calculator lets you estimate your power output requirements (in watts/kilowatts) for generators and home battery systems based on your household electricity needs.

But first, a quick note about starting and running watts — an essential consideration for portable or standby generators and home battery systems.

Many high-wattage appliances require significantly more power to start than to operate — especially devices that rely on a motor to run — like refrigerators, air conditioners, and washing machines.

Starting wattage is rarely an issue when using utility grid power. But it’s essential to ensure that any generator or battery storage devices, such as portable power stations, can output enough surge power and operating wattage to start all the appliances you want to run simultaneously.

Gas and inverter generators can only deliver 10% (or less) as additional starting watts above their operating output wattage.

EcoFlow solar generators and portable power stations offer up to double their running watts as surge power.

The Appliance Energy Requirement Calculator is powerful and easy to use.

Here are step-by-step instructions with examples.

Enter the name, running watts, and starting wattage requirements of the first appliance you want to add to your estimate in the appropriate fields. You can use the average requirements from the charts above or enter the specific requirements for devices and appliances you own.

2. Once you’re done, click on Add Appliances. Follow the same procedure from step one to enter the next appliance to your calculation.

3. Rinse and repeat until you’ve entered name, running, and starting wattage of every appliance you want to power.

4. Click “Calculate Total Watts” for your customized Energy Requirement estimate. In the example above, your generator or portable power station must provide 2100W of continuous AC output and 5700W of surge power to start and run all the appliances at once.

5. Made a mistake? Edit your input and recalculate — Or press Reset to start with a clean slate.
