The smooth flannel and warm boa make it feel like a dream. This season, a new USB warmer has been added to the classic winter cold protection series, which is popular for its thick flannel and gold foil prints. This year's pattern has a quilted line pattern, and the density of the pattern is higher than usual, making it easier to understand the characteristics of the sparkling foil print. The sheet-shaped multi-warmer with moderate cushioning has two built-in heating sheets, so you can open it or fold it in half and use it in a variety of situations! The good thing is that it is a USB cord specification, so you can easily use it not only at home but also in the office. The button on the main unit can only be operated with three levels of temperature control. The automatic OFF timer is fixed for 2 hours, but it comes with a safe function. When your hands and feet get cold, fold them in half, fasten the snap buttons on both ends, and put your hands in through the gaps on the sides to create a hand-in cushion. If you put it at your feet and put your toes in comfortably, it will become a foot warmer cushion. When unfolded, it can be warmed up over a wide area such as knees, seats, and hips. It is sure to be very useful in the office where it is cold from below! Comes with a zipper pocket for compact storage of cords when not in use. You can also store a mobile battery here. Power Supply: USB (TYPE A) Voltage: DC5V Cord Length: Approx. 1.3m 4 levels of temperature control: 40°C/45°C/50°C Automatic OFF Timer: 2 hours *It cannot be used continuously for more than 2 hours, so if you continue to use it after the automatic OFF, please turn it on again.
