Hanging Neck Fan Cooling Wearable Neck Air Cooler Portable Bladeless

Built-in semiconductor refrigeration elements. When the current passes through the loop composed of two different conductors, the Peltier effect will be produced, which will achieve the effect of heating on one side and cooling on the other side, forming a temperature difference, exchanging heat energy, and transmitting the cooling sensation in 3 seconds. to the skin for instant cooling.Fast cooling, cold aluminum temperature 22C, 3000mAh built-in battery, long battery life.The net weight of the product is 298g, and it will not feel heavy when you bring it2 in 1 design, with semiconductor refrigeration, left and right dual turbo blower design, 60 fan blades to gather windLet life be full of technology. Compared with most other portable neck-mounted fans, the neck-mounted radiator uses a smart chip to control the temperature, and uses the cooling principle of two pieces of aviation aluminum heat conduction fins. By cooling the neck and lowering the blood temperature, the blood circulates throughout the body to achieve the effect of cooling and heating the whole body, realizing true intelligence and wearability.Low Noise Design and Comfortable: to avoid the noise caused by the internal motor, fan blades, and air ducts of the traditional hanging neck fan, the portable neck hanging fan use low noise design. It is almost zero noise, suitable to use in any scenes. According to the ergonomic design concept, using selected high-quality soft rubber, it is more comfortable to wear.size:170x207x59mmMaterial:ABS+Aluminumcolour:WhitePackage Contents:1 * Hanging neck fan1 * USB cableOnly the above package content, other products are not included.Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing.
