2-Speed Adjustable Mini Handheld FanWith 2 blades, it creates a stream of airflow to keep you cool and relaxed. Press the power switch repeatedly to adjust the proper fan speed. (Speed 1 lasts 4 hours, Speed 2 lasts 2.5 - 3 hours when fully charged.) Practical USB Rechargeable Mini FanCan be used at home, office, school while sleeping, working, eating, connect to any computer/laptop via USB, or connect to an AC port with a USB AC adapter. This is the best gift for family, friends, colleagues and teachers. Mini Size, Portable and Foldable Handheld FanFoldable at 270 degrees, small enough to put in your pocket or bag, hold it or stand it as a desk fan. To prevent the fan from falling back if it is hit on a tabletop, do not place the fan on a very slippery surface. Soft BladeWhen the hand touches the rotating fan, the fan will stop and the hand will feel very slight pain (no injury). Be careful when using it, or you will be scratched by the blade. It is recommended that children under 10 years old do not put their hands in the fan to avoid scratches.
