Now why should an umbrella be equipped with a fan? Those residing in tropical climates may well know the answer.
Although logically rain showers may seem to cool down the temperature; it does not happen at all times. And that is when this Fanbrella comes to action to tackle the humid climate [at least your face gets cooled]. Apart from the rainy season this should be a relief for summer too ; you get shaded from the heat as well as cooled.
The folding fan runs on three AA batteries, the switch of which is located on the handle. At a stretch one can enjoy 2-3 hrs. of cool air.
