Battery Thermokruzhkus Mug

Battery Thermokruzhkus Mug 1

In addition to providing you with your usual dose of power source, caffeine; the Thermokruzhkus is a coffee mug with a battery that powers up when you fill it with your favorite hot beverage. This 10 ounce ceramic mug is classic black with a white outline of a battery on it. Pour in your hot liquid – anything over 96.8F (36C) – and watch the green cells within the battery light up. As you ingest your beverage or as it cools, the battery will fade into emptiness, reminding you that you need a refill. For the gamers, there’s also a pixellated “life” heart that fills and empties.
