FAQ

What's the difference between running and starting watts?

Running watts are the steady draw while an appliance operates. Starting (surge) watts are a brief spike, often 2–3x higher, when a motor or compressor starts. Generators and power stations must handle the biggest starting surge on top of everything else running.

Note: These are estimates. Real consumption depends on the exact model, its age, settings, room temperature and how you use it. For your exact number, check the appliance's label or measure it with a plug-in energy meter. Rates are August 2026 state averages from the EIA; check your bill for your actual rate. When powering appliances from a generator or power station, never exceed its rated output and follow the manufacturer's safety instructions.
