1. The portable hanging neck fan is a must-have item for wearing a mask comfortably in summer. Compared with ordinary fans, our fans have excellent features such as high durability, energy saving, quietness, and low noise. Strong winds can be achieved using high-power motors. In addition, 7 blades that generate strong wind are used, and the design that allows the most airflow through produces diffused wind. Enjoy the coolness of summer anytime, anywhere without worrying about disturbing others.2. The neck has a built-in 3000mAh high-capacity lithium-ion battery, which can be fully charged in about 3 hours. Each time you press the power switch, the fan air volume can be divided into three levels: "weak", "medium" and "strong", allowing you to fine-tune the heat dissipation according to your own preferences. The battery life is about 12 hours in the first gear, about 7 hours in the second gear, and about 4 hours in the third gear, which can keep you comfortable even if you go out for a long time.3. The fan can be connected through a USB cable and used as a mobile phone battery. Great for emergency charging of phones and USB devices on the go. Carrying a portable fan and phone battery at the same time can be bulky, so the 2-in-1 type allows you to reduce the amount of luggage in your bag and move it around with ease.4. The top of the hand-held fan can be adjusted up and down 180°, allowing you to adjust the fan up and down while watching sports games, allowing you to enjoy the cool breeze from your chin. It can also be used as a mobile phone stand, allowing you to enjoy the coolness while chasing dramas.5. The main unit weighs about 145g. The body is lightweight, so you won't get tired even if you hold it for a long time. It is a combination of fan and cell phone battery and is recommended for office and outdoor use. Not only that, but it can also be used for study, travel, camping, fireworks festivals, sports festivals, hiking, commuting, etc.Voltage: 5V/1AWorking current: 1600MAGear: There are three gears, press 1 for the next gear, press 2 for the second gear, press 3 for the third gear, and press 4 to close.Battery life: 1st gear/12 hours, 2nd gear/7 hours, 3rd gear/4 hours.Battery capacity: 3000mAhCharging time: about 3 hoursColor: white, pink, green, blueSize: 16.6*8*1.8cm/6.6*3.2*0.7inFully charged: 4 power indicator lights are all on without blinkingPackage includes: 1X Fan1X Instruction manual1X Lanyard1X Data cable
