Isn't that just the power % option? I don't think mine is fancy but I can adjust the power %

Unless you have an inverter microwave it simply adjusts the % of the time that the magnetron is turned on. So at 50% you will have the magnetron at full blast 700W for 5 seconds and then 5 seconds off (or similar timestemps). On older microwaves you may be able to hear the magnetron cycling between being on and off.

I have a new microwave and can definitely hear the magnetron cycling, but it's a fairly subtle difference in sound.
