Adding more satisfaction to the simple act of taking a sip

Ember is on a mission to create enjoyment by adding precise temperature control to the way we eat and drink. The company’s advanced thermal technology cools and heats food and beverages while maintaining precise temperatures for hours. Working in partnership with Ammunition, the company’s first product is the Ember Mug—the world’s most advanced temperature adjustable mug for enjoying coffee and other drinks exactly the way you like them.


Ember was designed to add comfort to drinking your favorite beverage, not to force interaction with controls or quantify drink consumption. Our goals with the design were to use Ember’s technology to lightly augment the things people already expect from a satisfying drinking vessel and to add as few visible features as possible.

A capacitive touch button behind the Ember logo powers on the mug and reveals the temperature display. The mug has a subtle bottom dial that can be twisted to adjust the temperature up or down. The lid has a push to open mechanism that securely seals in liquid and prevents spills, along with a 360° design so you can drink from any side. Ember’s charging coaster features elegant circular contact rings so the mug can charge without specific orientation.

The light up display on the mug lets you know when your coffee is just right, and there’s no need to set it again unless you want to change your target temperature. The simple app lets you change your temperature remotely, as well as check on your drink’s temperature and how much is left. You can also check the mug’s battery level, turn the power on and off, and input presets. The Ember app can also notify you when your drink has heated or cooled to your ideal temperature.
