The Battery Thermokruzhkus Mug, available at ThinkGeek, helps you power up when your energy levels are low.
Caffeine is our power source, whether it’s from coffee or tea or BAWLS. What better way for us to visualize our batteries being charged than a mug with a battery that powers up when we fill it with our piping hot caffeinated libation of choice?
This 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 your beverage cools (or is ingested) the battery will fade into emptiness, reminding you that you need a refill.
