This is the ideal mug for coffee drinkers who are constantly on the move. The Hot Rod Heated Travel Mug ($25) keeps the coffee hot – the thermally-insulated mug maintains its heat long after you brewed or bought your coffee. The Hot Rod provides supplemental heat to preserve the temperature that is ideal for an enjoyable cup – it’s a feature that most travel mugs in the market lack; hence, they fail at doing their intended functions effectively. The mug has a temperature gauge – you can easily tell when your boiling-hot coffee will be ready for consumption. Also, it has a built-in DC adapter that you can plug right into your car's cigarette lighter 12v outlet to maintain your coffee's optimum temperature. The Hot Rod’s glossy candy-shell exterior makes it a pleasant fixture on your hand, your car, or your office desk.
