Portable Conditioner Neck Fan,Semiconductor Neck er Conditioner Wearable,for Travel, Home, |Fans( ) Let life be full of technology. Compared with most 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 temperature, the circulates throughout the body to achieve the effect of cooling and heating the whole body, realizing true intelligence and wearability. Semiconductor peltier-thermoelectric module er efficiency:11 degree-16 degree lower than ambient temperature mode Low mode: lower down around 9-11 degree High mode: lower down around 16-18 degree supply mode USB cable to supply power Low mode: around 350min ,High mode: around 200min Size adaptation Adjustable and extendable size for most people,(with 10000mah power bank). Attention Please do not cover the wind holes at the two side of the device, which will effect the cooling function. Operation on: Press the power/mode button for around 1-2 seconds until the light is flashing.Low mode: when power on, the device enter into low mode.High mode: when the device is in low mode, press the power/mode button for one timeto enter into the high mode and the light will be on.
