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. The regular price is about 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. It will be shipped in the original box. I have checked that it powers on and works. The blue lamp is on (photo). # Neck Cooler # Neck Fan # Neck Fan # Fan
