This is a generously sized checked blanket that comes with an integrated circuit. You know when it is operating because the LED digital display will be lit. You can choose a high, medium, or low temperature to get the level of heating that you desire.
It is powered by a 12-volt low voltage power supply (eight-foot-long cord) such as that provided inside a car and complies with safety standards, including CE, ETL and c-tick. The outer layer can be detached and is easy to clean by wiping down with a cloth. It is also soft and comfortable.
