Compact Handheld Fan with Extended Battery Life Portable USB Rechargeable Cooling Device for Outdoor Activities Green

• 【ICE Super Refrigeration Technology】 Blows 16 ° C cold air without fear of cost, using ICE superconductor refrigeration+high-speed turbine engine to deeply compress air to reduce temperature, converting 40 ° C hot air into 16 ° C cold air. • The ultra high speed turbo engine has a hard core power of 29000 revolutions per minute, overcoming wind power challenges and utilizing high-speed hair dryer technology to significantly improve overall performance • Aviation grade turbofan blades soar 10 meters of cold air, utilizing aviation grade technology combined with aerodynamics to generate stronger and stronger winds • The 'Hurricane Eye Turbine Wind Tunnel' provides 360 ° wide area spiral air supply, simulating the principle of a hurricane center turbine and rotating the airflow 360 ° spiral air supply. • The new design features a 120 ° expansion ring that blows soft air all over the body, rejecting harsh winds (allowing cold air to be sent into the inside of clothes). The six major air duct convection system sends the cooled cold air to the back an
