Electric blankets designed for use with 12 volt systems are generally energy-efficient. They require minimal power to operate, meaning you can keep warm without draining your vehicle’s battery. Most blankets draw less energy than traditional space heaters, making them a sustainable choice for eco-conscious campers. Additionally, they heat up quickly, so you won’t need to keep them running for long to achieve comfort. This efficient use of energy makes them an ideal companion for long camping trips.
