Heated and cooled vest equipped with four Peltier elements. - Model: PV555 - Size: L - Cooling Temperature: -23℃ - Heating Temperature: 50℃ - Battery Capacity: 14,000mAh - Input: USB Type-C - Brand: HOOH Thank you for viewing. I've only used it for about 3 hours. I'm selling it because I don't have a chance to use it. Everything is included, such as the battery and charger. I have the box and will pack it for shipping. It can also be heated, so how about using it for winter motorcycle touring? It seems good for fishing too(^^) Thank you very much(^^)
