A 12V heated car blanket plugs into the auxiliary power outlet of a car, truck or RV and warms a passenger on a cold drive. Most are small throws of about 60 by 40 inches with a long cord. A few add a timer or an app, and some are meant for camping.
The six blankets below range from simple fleece throws to a 12V/24V flannel and sherpa model and a camping blanket with app control. Sizes, fabrics and features come from each product’s listing page. We have not used these blankets ourselves, and we make no safety claims; certifications and temperature ranges are the makers’ statements. Follow each manual, watch your car’s battery and never leave one on in an unattended vehicle.
