The LUMENA N9-FAN CLASSIC Wireless Oscillating Pedestal Fan gives you optimal wind without the sound. This classic-looking standing fan offers five wind speeds along with a natural wind mode. And even though it operates at just 12 decibels, it can still move wind up to 45 kilometers per hour. In fact, this indoor fan can push air as far as 19 meters away. Furthermore, this classic fan will operate throughout the hottest part of the day. It’s wireless, so you won’t trip over cords while you have it on the highest mode—and its battery life is two hours on this setting. If you keep it on low speed, this oscillating fan will continue to pump out wind for 46 hours thanks to its 10,400 mAh battery. This wireless fan has a 13″ diameter to keep your room cool without obstructing any views.
