Have you ever gotten in your car on a cold winter day only to realize you need to waste some time to defrost your car’s windshield and warm the interior? This Car Interior Preheater can make your life easier. This battery powered heater does not draw power from your car and can heat the interior for up to 20 minutes before you come inside. Just put it on the dashboard, turn it on from up to 200′ away, and you are set. When you are done, recharge the battery, and you are ready for the next time. Certainly nice to have one of these winter time.
