Product Details Dimensions: 75 depth x 35 width x 75 height mm [2024 Summer Evolution & Handheld Fan & Ultra-Quiet 20dB] Our handheld fan adopts the latest brushless DC silent motor, which has superior features such as high durability, high power, quietness, and low noise compared to conventional brushless DC motors. Unlike commercially available brushless motors, our brushless motor has a grooved structure on the bearing, which further reduces friction, reduces heat generation, improves motor durability, increases efficiency, and extends battery life by more than 50% compared to conventional products. With an ultra-quiet design of 20dB, the motor noise is low and the vibration is small, so you can feel the cool breeze while studying or working and complete your tasks efficiently. It is indispensable as a heatstroke prevention item in the hot season. [5200mAh Large Capacity & LED Digital Display] The handheld fan has a built-in 5200mAh large-capacity battery and can operate for a long time. The new battery has undergone long-term testing to avoid the risk of explosion, and uses a separate lithium battery to avoid overcharging and short circuits, effectively extending its life. Fast charging and long-lasting: 2-3 hours to charge, depending on the wind speed level of the small handheld fan, up to 9 hours on the maximum gear (can be used for 24 hours on 2-3 gears!), Equipped with an LED display, the battery power and wind volume are clear at a glance. Compared to conventional fans, this fan uses a digital display for battery power and wind volume, so you can more intuitively feel the current battery status of the fan, solve the problem of insufficient power during operation, and at the same time control the wind volume more accurately. [5-Level Wind Speed Adjustment & Natural Wind Mode Intermittent Air Supply] This handheld fan has a 5-level wind speed adjustment function, and each time you press the wind speed adjustment button, you can fine-tune from natural wind to powerful wind. It adopts the latest turbine blade fan, which is streamlined according to human functionality, enhances the protection function of the fan surface, and effectively prevents injuries such as fingers and hair. 1 is sleep wind, the lowest speed of 1 is recommended for sleep and rest. 2 is natural wind, which feels like a gentle breeze, simulating the flow of natural air. 3 and 4 are strong wind and super strong wind, and the strong wind mode provides a stronger and cooler breeze, perfect for field activities. 5 is circulating wind, which intermittently sends out air, allowing you to feel the gentleness of natural wind up close.
