The primary advantage of 100-level speed adjustment is precise control and personalized experience. Traditional fans typically offer only 3-5 speed settings, while our product provides 100 levels of fine adjustment, allowing you to find your "perfect airflow." This fine-tuning is particularly useful in various scenarios: for instance, lower speeds in public spaces when quietness is needed; higher speeds in outdoor or high-temperature environments; and appropriate speeds for nighttime sleep to avoid excessive or insufficient airflow. Additionally, as battery power decreases, you can gradually lower the fan speed to extend usage time, achieving more efficient battery management and a more comfortable user experience.

The turbine design is a special fan structure that mimics the principles of aviation turbine engines, compressing and accelerating incoming air through specially designed air ducts and blade shapes before discharging it forward. Compared to regular fans, the turbine design offers these advantages: 1) Stronger, more focused airflow with greater range; 2) Greater air volume production in the same size; 3) Higher air pressure, effectively penetrating clothing to draw away heat; 4) Relatively lower noise, especially at low to medium speeds. Our turbine fan can provide effective airflow even at distances of 1-2 meters, making it particularly suitable for outdoor use or scenarios requiring long-distance air delivery.

The high-speed turbine mode is a special rapid cooling function. When the fan is operating normally, double-click the button to activate high-speed turbine mode, at which point the fan immediately switches to maximum speed (equivalent to level 100) without needing to gradually adjust via the dial. This mode is particularly suitable for these scenarios: 1) Needing quick cooling after entering from a hot outdoor environment; 2) Requiring immediate cooling after sweating profusely from exercise; 3) Needing rapid airflow in emergency situations. In high-speed turbine mode, the fan continuously operates at maximum power, providing the strongest airflow, but also accelerates battery consumption, with continuous use lasting approximately 3.5 hours. To exit high-speed mode, simply press the button once more to return to the previous speed setting.

The LCD display primarily shows two important types of information: fan speed level and battery power. When the fan is running, the display shows the current fan speed level (1-100) in real-time, changing synchronously as you adjust the dial, allowing you to precisely monitor the fan speed status. When the fan is powered off, briefly press the button once (without starting the fan) to display the current remaining battery percentage, for example, "85" indicates 85% remaining battery power. This feature is particularly useful, allowing you to understand the battery status at any time and plan charging accordingly. The display adopts an energy-saving design, automatically dimming after the fan has been running for a while to conserve power, and brightening again after any operation.

To extend battery life, you can adopt the following strategies: 1) Select lower fan speed levels; levels 1-30 consume significantly less power than higher levels, extending runtime from 6 hours to nearly 20 hours; 2) Avoid using high-speed turbine mode for extended periods, activating it only briefly when necessary; 3) Turn off the fan promptly when not in use, which can be done quickly by pressing and holding the dial; 4) Maintain proper charging habits, avoiding complete battery discharge before recharging; 5) Avoid extended use in extremely high-temperature environments, as high temperatures accelerate battery consumption; 6) Periodically perform a complete charge-discharge cycle (1-2 times per month) to help maintain battery health and accurate power display. Additionally, carrying a power bank allows you to charge the device when necessary, further extending usage time.
