Your hot cup of coffee in the morning, or cold glass of beer at night, may help refresh you—but that’s not all it could do. The two-sided Epiphany onE Puck converts the warmth of your hot cocoa or iced beverage into power for your phone. The lightweight device is portable enough to store in your purse or day bag for emergencies.
The wireless charger works with all Apple products, Android devices and phones that use an USB drawing 1000 mA or less power.
Using a small Stirling engine within the device that runs on heat disparities, the Epiphany OnE Puck siphons and transforms the heat or cold of your hot or cold drinks into power for your phone.
The device has two sides: one for placing hot beverages—such as tea, coffee or soup—the other for cold, such as beer, milkshake or fruit juice.
As your hot drink cools down, or cold drink heats up, on the respective side of the coaster, its Stirling engine would turn and generate electricity to charge your phone.
