1. Leafless 360-Degree Surround Mini Fan The latest fashionable design addresses some drawbacks of traditional neck fans. It features a unique leafless design, reducing the risk of hair being caught by the neck fan and getting injured. The turbo fan generates strong cold air and reduces noise, providing 360-degree cold air surround, which can quickly cool the air around your cheeks and alleviate the stuffy feeling caused by masks. 2. 62 Surrounding Air Outlets The DDKJ portable fan uses a U-shaped design and can be used by hanging it around your neck. The middle part of the mini fan is made of soft TPR rubber material, allowing you to freely adjust it to the desired angle. It has 62 surrounding air outlets, increasing the air volume and achieving 360-degree surround heat dissipation. Two turbo blades are added on both sides of the fan to reduce air fluctuations. 3. Three Wind Speeds The silent DDKJ handheld fan offers three adjustable wind speeds: low/medium/high, and the operation is simple. With a one-button design, you can switch between speeds by pressing the button. The high-power motor can keep the noise level relatively low (about 30 decibels) while generating strong wind. Therefore, this USB handheld fan is a good option to provide a strong air volume with less noise disturbance. 4. 3000 mAh, 8-Hour Battery Life The DDKJ wireless fan is built-in with a 3000 mAh lithium battery. It can be charged through the USB port of a power bank or a laptop. It takes 3 - 4 hours to fully charge and can be used continuously for up to 8 hours. With a large-capacity battery, it reduces the need for frequent charging, and you don't have to worry about power outages easily. The 220-gram design is lightweight and won't put much burden on your neck. You can free your hands and use it conveniently anytime and anywhere. The DDKJ USB fan is a suitable option for your outdoor activities (such as personal cooling, office work, cooking, fitness, camping, traveling, hiking, mountain climbing, and watching games, etc.).
