The runtime of a lithium-ion battery fan is not fixed and is affected by several factors. Among these, the fan's power and battery capacity are the two most important. A higher-powered fan, while producing stronger airflow, also consumes more power, resulting in a shorter runtime. Battery capacity directly determines how much electricity the fan can store; a larger capacity naturally leads to a longer runtime.
Furthermore, usage patterns also affect runtime. For example, prolonged use of the fan in high summer temperatures or in strong outdoor winds will accelerate battery consumption. Therefore, adjusting usage patterns appropriately can effectively extend the runtime of a lithium-ion battery fan.
