• AI aggregation cooling, turbo system instantly gathers ice and provides strong cooling sensation. Upgrade the diversion duct to superconducting cold flow, once again refreshing the industry standard of tactile ice cooling technology. According to t • O-type global air supply+five levels of high wind capacity, one level stronger than 100 levels, instantly refreshing. The dominant high air volume, with one level stronger than 100 levels, significantly increases the wind power by 165% compared to • Smaller, air-conditioned, ultra wide angle air supply crushes traditional point-to-point blowing. 30 channels of simulated air conditioning style ultra wide angle cold flow air chamber, highly restored air conditioning ultra wide angle full range s • Silent to reach a higher level! Deep noise reduction, no noise, no noise. Upgraded audio motor and implanted acoustic noise reduction shell to reduce decibels, and made sound insulation improvements to the aerodynamic air duct, effectively blocking • Endurance! Better than others, it can sweep away travel anxiety in 12 hours. With high-capacity batteries, it uses a variable frequency three wire motor to extend the range performance. The battery adopts intelligent variable frequency algorithm, w
