This is a heat-retaining hot water bottle that doesn't require hot water. I bought two, but I no longer need one, so I am selling it. The box is damaged, so I listed it as "Like New," but it is a brand new, unused item. Thank you. 【High-Efficiency Heating】 It charges in about 15 minutes and can maintain heat for up to 8 hours. It warms up quickly, so you can feel the warmth immediately. 【Compact Size】 The main body size is 18cm wide x 26cm deep, and it comes with an insulation cover, making it convenient to carry and store. - Product Name: TTC-U2 Fuaa Heat-Retaining Hot Water Bottle - Power Consumption: 300W (Maximum Power Consumption) - Charging Power: AC 100V 50/60Hz - Charging Time: Approximately 15 minutes - Usage Time: Approximately 4-8 hours - Body Size: 18cm wide x 26cm deep - Insulation Cover Size: 20cm wide x 27cm deep
