A new device lets you charge your phone on the go with the beverage of your choice. This is the Epiphany onE Puck and it uses a heat engine to power your phone. You can place your hot or cold beverage on the surface while you enjoy a cuppa.

The charger works in extremes, so the colder or hotter your drink, the quicker your phone will charge. Prototypes are available on Kickstarter for $115 and backers can get the choice to customize the charger with engraved text.
