Yes, the limitation for this is related to the power draw. The plugs are designed to support a light load like a light bulb or two, but cannot accommodate heavy equipment. In general, anything that is using a heating element or motor is not recommended because it requires a large draw of electricity (even if only at the beginning of use).Examples of products that we DO NOT recommend using with Motion Wi-Fi Sensing Plug include but are not limited to space heaters, clothes irons, hair dryers, curling irons, microwave ovens, vacuums, or blenders.
