1.Powerful Wind Power: If you are looking for a quiet fan with weak wind power, please don't choose it, this is a real turbo fan with strong wind power, while it needs to move the air quickly, it will produce a certain amount of sound. The power consumption also changes depending on the power you select.Use your imagination, it will have endless uses! 2.Turbofan Design:Aluminum alloy fan blades and an integral solid fuselage with the same structure as the turbofan engine. The engine has a maximum speed of 180,000 and an operating time of 2.5 hours at the lowest wind speed and 30 minutes at the highest wind speed. Note that the lowest wind speed is also much more powerful than any mini fan handheld you've ever owned! 3.Applications: Many applications are possible with this hand held fan apart from cooling your body on a hot day. The included round nozzle allows you to inflate all devices that need to be inflated, such as Car Air Mattress,Camping Sleeping Pad,beach volleyball.It could be used to stimulate a fire in your wood burning stove/fireplace. It could be used as a duster in your home. Along those lines, you can use it to clear dust from your vehicle as part of the detailing. This thing is like a compact leaves blower that you can hold in your hand! 4.LCD Screen Display:The battery fan comes with 2 nozzles, a user manual, a 1.5' Type-A to Type-C USB charging cable and a lanyard.It charges with a USB cord with a type c connector on the side of the body.It has a led indicator on one side which shows the charge level when plugged in and when it is running it shows the fan speed while adjusting it and & the remaining battery capacity while running. Very neat feature.
