It’s about time your morning cup of coffee quit being just a caffeine dump and started providing support for your electronic devices as well — at least, that’s the thought process that produced the Epiphany onE Puck charger. According to the folks over at Greatist, the coffee-powered charging pad converts the energy produced by the temperature of a hot (or iced) beverage into chargeable power of up to five watts, which is about the same amount used by a traditional smartphone charger. Another bonus? The device is compatible with all iPhones, iPads, and Androids, meaning that it’s accessible for pretty much any phone with a USB charger.

The only downside is the fact that the charger’s effectiveness will vary a lot depending on how hot or cold a particular beverage is, but we’ll take some environmentally friendly variation over being trapped in a Starbucks with no available outlets any day. The onE Puck charger is not yet available for sale, but you can track its progress here.
