Calculating Power Consumption: Running vs. Starting Watts
This is where many first-time buyers get tripped up. Every electrical device has two wattage ratings:
- Running Watts: The continuous power a device needs to operate.
- Starting Watts (Surge Watts): The brief burst of extra power some devices (especially those with motors like refrigerators, air conditioners, or power tools) require to start up. This can be 2-4 times their running wattage.
Here's how to calculate your needs: - List all devices: Make a list of everything you plan to power simultaneously.
- Find Running Watts: Note the running wattage for each device (usually on a label or in the manual).
- Find Starting Watts: Identify the device with the highest starting wattage.
- Calculate Total Running Watts: Sum the running watts of all devices.
- Calculate Total Starting Watts: Take your total running watts and add the highest single starting wattage from your list. This final number is the minimum starting wattage your generator needs to handle.
Example: If your fridge needs 600 running watts and 1800 starting watts, and other devices total 1000 running watts with no significant starting surge, your generator needs to handle at least 1600 running watts (600 + 1000) and 2800 starting watts (1600 + 1200, assuming the fridge is the highest single starting load).
