In order to reduce noise, this halterneck fan reduces the intensity of the fan outlet, the air outlet of this product is relatively soft, the wind force is moderate, and it will not cause any harm to the human body, if the product wind is too strong and wears for a long time, it will cause dry skin, respiratory irritation, headache or joint pain So its air volume will not be very strong, mainly relying on and cooperating with the semiconductor refrigeration sheet to produce the cold feeling from the cold feeling (if you can't accept the soft wind, please do not buy and return, If you just want to buy a halterneck fan with strong wind and does not rely on semiconductor cooling, you can check other products in my store), and this product has a heating function, which can be used as a scarf in winter, thank you
