Lightweight and portable white wearable fan. - Model Name: WK-001 - Color: White - Weight: 180g - Battery Capacity: 18650 3.7V - Power Consumption: DC 5V 1A Thank you for viewing. I purchased this in the past and have never used it. It has been stored at home after opening. There are no instructions or charging cable, but it can be charged with a type B USB cable. The box shows signs of deterioration, but the contents have never been worn and are new. After cleaning with alcohol, I will pack it in packing materials and ship it.
