The Ember Smart Mug 2 is a battery-powered ceramic mug that holds a drink at a temperature you set in the Ember app, typically from 120°F to 145°F. A hidden heating element and a pair of sensors keep the liquid steady, and the LED light on the base tells you when it has reached the target. It suits desk workers, slow coffee drinkers and tea drinkers who want the last sip as warm as the first. Against a plain insulated mug it adds precise control and a battery, but it costs far more, holds less, and needs charging or a charging coaster.

Owners like the steady, exact temperature and the solid feel, and many call it a favorite for desk work. Complaints center on battery life, the small capacity and the need to hand wash.
Ember Mug² is a smart mug designed for home or office. It lets you set an exact drinking temperature for your coffee, so it stays at the heat you choose rather than going too hot or too cold.
