I'm selling this because I bought it for my family, but the person already bought one, so I have a duplicate. It has a Peltier element (cooling plate) on the neck, so it's a comfortable type, not just a fan. This neck fan is USB rechargeable and has a 5200mAh battery. - Model Name: NECK ICE FAN - Size: 185 x 63 x 199mm - Power: USB rechargeable - Battery Capacity: 5200mAh - Power Consumption: 10W - Material: ABS resin Shipping will be via either Yu-Yu or Rakuraku Mercari delivery, depending on my schedule. Please let me know at the time of purchase if you have a preference.
