This neck fan has a Peltier element (cooling plate) on the neck, providing a comfortable feel in addition to the fan. It's a USB rechargeable neck fan with 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.
