Like every machine, the human body needs to be recharged from time to time. For our machines it's having enough batteries in stock – for us it's coffee!

Ah... nothing quite refreshes like a hot cup of coffee. Or maybe tea. :) This mug visualizes what you feel: Pour in a hot liquid (like coffee, tea, chocolate, lava) and watch the charge bar reload up to 100%*. Less coffee or cold coffee means a lower energy level. Cool, huh?

And just in case there's anything unclear about this, a manual is printed on the battery mug, as well as all the important facts about capacity and content.

*** Possibly doesn't****
**** OK, it might...
