Lightweight at just 279g, this neck fan is designed to provide maximum comfort without weighing you down. Equipped with a powerful 4500mAh battery, it offers an impressive working time ranging from 3.5 hours to 21.5 hours, depending on the selected wind speed. The fan features advanced technology that delivers a strong wind speed of 3.8m/s, ensuring effective cooling wherever you go. With its 3+1 speed settings, you can easily customize your cooling experience. A single short press adjusts the fan to the first gear, two presses for the second gear, and three presses for the third gear.

This straight-through non-destructive structure ensures that up to 98% of the air output is maintained, providing a much stronger breeze compared to older models. The fan's performance is further enhanced by its brushless motor, which operates quietly at just 39.7dB quieter than typing on a keyboard. Styled in trendy Macaron colors, the JISULIFE Comfortable Neck Fan not only cools you down but also adds a pop of color and vitality to your look. Its ergonomic design prioritizes user comfort, featuring a gimbal made from skin-friendly material on the back of the neck. This reduces the contact area between the fan and your skin, making it more comfortable to wear for extended periods. Additionally, the fan's size is adjustable to fit various neck circumferences, ensuring a perfect fit for everyone. Charging the fan is fast and convenient thanks to its Type-C interface, complete with a charging indicator to keep you informed of the battery status.
