This USB powered hot blanket features 3 temperature control buttons to adjust the temperature to suit your indoor or outdoor environment to create a safe space for dogs and cats to relax in. With two safety functions, you can control the temperature control (automatically shut off after 6 hours after pressing the button) or sudden temperature rise (temperature controller). It can be used as a favorite space such as a bed or couch, or as a car or carry, or as a protection against the cold during disasters. This blanket type heater is easy to carry and easy to match with items and spaces, making it easy and convenient for daily use. The front is made of thick knit fabric and the back is reversible with fluffy brushed fabric. The fabric part is hand washable, so you can remove odors and stains and keep it clean. To prevent tampering, the long USB cord is covered with a metal tube. Connect the USB port on the blanket side to the power bank or USB adapter to supply power.
