Usually caffeine is the only thing that recharges people. Some like to have a hot mug and some want cold. What if your mug becomes an indicator of what is going one with your coffee? Animated Battery Coffee Mug does this job. This ceramic mug features battery indicator which shows green when anything over 96.8F (36C) is poured and when your liquid goes cooler the battery will fade into emptiness, telling you that you need a refill.
