The Ember Smart Cup is a 14 oz battery-powered mug that holds coffee at a temperature you pick in the Ember app, from 120°F to 145°F. The built-in battery keeps that temperature for up to 2.5 hours with the included sipping lid, or all day on the charging coaster. Auto sleep turns the heat on and off as you drink. It suits desk workers and slow sippers who hate reheated coffee. Against a plain insulated mug it adds exact temperature control and app presets, but it costs far more, holds less than a 20 oz travel tumbler, and needs charging.

Owners like keeping coffee at a steady temperature through long meetings and slow mornings, and call the app easy to set up. Common complaints are battery life off the coaster and the need to hand wash.
The Ember Cup is a 14 oz smart mug for home or office. It lets you set an exact drinking temperature and then keeps your drink at that temperature. With the included Sipping Lid, it holds the temperature for up to 2.5 hours.
Temperature is set in the Ember app, which connects to the cup. In the app you can set your temperature, customize presets for your favorite drinks, get a notification when your drink reaches the chosen temperature, and personalize your mug. A smart LED shows when the beverage has reached its temperature. Auto sleep senses when to turn the cup on and off.
The built-in battery runs for 2.5 hours with the included lid. Placed on the charging coaster, the cup can stay powered all day. The cup is hand wash safe and submersible up to 1 meter in water. The Sipping Lid also makes it usable on the go.
