The ThinkGeek Battery Thermokruzkhus Mug lets you know when your beverage is ready to power you up. The geeky ceramic cup appears ordinary at first, but the magic begins when you pour your piping hot brew in.
The black mug features an outline of the classic power bar icon. As hot steamy liquid flows into the vessel, the icon begins to light up neon green. The cup not only signals when it is full, but also powers down when it's time for a refill. This high-tech mug requires some tender loving care, so think twice about throwing this into the dishwasher. It provides a practical indicator to prevent you from guzzling down cold, leftover coffee -- yuck.
Your co-workers will envy your brew as you sip away from the ThinkGeek Battery Thermokruzkhus Mug.
