The Epiphany onE Puck powers devices without the need for a wall socket.

The Epiphany onE Puck charges a phone without it needing to be plugged into a wall socket. The compact heat engine uses the heat or cold from your drink to power your device.

Simply place your hot drink on the red side of the ‘coaster' or your cold drink on the blue side and plug your USB charger into it. The lightweight and portable gadget connects to your iPhone, Android, or similar device.

It was developed by Epiphany Labs, a group of technologists and business professionals who aim to develop products that create positive changes throughout the world. The ‘Epiphany onE Puck' uses a stirling engine powered by heat disparities, such as a hot or cold drink, a candle, ice, etc. These heat sources provide enough power to the stirling engine to fully charge a phone battery.
