    This device appears to be well-made. It has everything you need to charge and then use the block to charge whatever needs charging, including your car. It is residing in my car for the winter season. Living in Alaska with temps getting to 40 or 50 below, one does not want to get into your car to find a dead battery. This is the perfect product to give me peace of mind when I am out and about.
