Stainless Steel Smart Mug
Here's another way to make sure that your hot beverages stay hot in your vehicle. Plug the mug base into your cigarette lighter outlet and you'll be able to heat liquids to selected temperatures from 85 to 160 degrees. The LED indicator notifies you when your drink reaches the desired temperature.
Ok, this is exactly what I need in my car!! Plugging in the cup will keep your coffee warm and will let you know when it's at the ideal temperature. So cool!
