Have you ever been drinking your coffee or hot tea and didn't realize you were about out until it was too late? By the time you got to the coffee pot one of your annoying coworkers grabbed the last drop for himself? Never let that happen again with the Battery Morph mug.

The mug has a battery painted on the side and as the liquid heats up the mug, the battery level rises. When you have a full cup, then you have a full battery. As you drink the liquid down, the cup cools and the battery level decreases. Keep your eye on the charge and you'll never be the last one to the hot coffee again with the Battery Morph Mug.
