A battery operated electric blanket is a heated blanket that is powered by batteries instead of the current from an electrical outlet. They contain battery compartments that are typically placed in the corners of the blanket.
The batteries power a network of heating elements that distributes the heat evenly throughout the blanket. These blankets typically include controls which allow users to set the heat level and enable auto shut off. Battery powered electric blankets are considered safer than traditional electric blankets because they operate on 12 volts of power instead of 120. Since they do not require an electrical outlet, they are a popular choice for camping, traveling and outdoor events.
