Almost none. It only runs when it need air. When you pull the trigger on your sprayer it runs and shuts off almost immediately when you let go. It doesnt have a tank to.fill like your pancake. Just for interest i tried to run some tools.that use lots more air and they wont run. Its kind of expensive just for this use but since i use it to run an air rush its kind of nice to get dual.usage.
