Neck Cooler Like new With instruction manual I purchased it and opened the box, but I haven't used it. I bought it on Rakuten Ichiba. It's a product that originally cost around 10,000 yen. You can wear it around your neck, so it's convenient because your hands are free. The charging time is about 4 hours from zero battery to full charge. It can be used for about 4 hours on normal airflow. It can be used for about 8.5 hours on low airflow. I will ship it in the box it came in. I have checked that it powers on and works. The blue lamp is on (photo). # Neck Cooler # Neck Fan # Neck Fan # Fan
