The soft fleece blanket plugs directly into your car's 12V power outlet or cigarette lighter. The 8' cord means anyone can use it, even in the way back of the 3rd row seats in your SUV, and measuring 55" x 40" it's big enough to share. Get comfortable no matter the weather outside with the blanket's 3 heat settings. For safety, the blanket has an auto-shut off feature that can be set for 30, 45, or 60 minutes, so you don't have to worry about children or sleeping passengers overheating. Even without the extra heat function, the polyester fleece makes this a perfect lap blanket in the car. Unlike other electric car blankets, this one is machine washable, just remover the detachable cord and wash in cool water on the gentle cycle, tumble dry low or air dry. Available in Gray polyester fleece.
