The Ember Smart Mug 2 is a 10 oz ceramic mug with a built-in battery that holds your drink at a set temperature instead of letting it cool. You pick the heat in the Ember app or use the 135°F preset, and an LED on the mug and in the app tells you when it is ready to sip. The battery runs roughly 80 to 90 minutes, and the charging coaster keeps it going all day at a desk. It suits slow coffee drinkers and office workers more than people who finish a cup in five minutes; plain insulated mugs keep drinks hot far longer for far less, but they cannot hold an exact temperature. Owners like the app control and the ceramic feel, and criticise the battery life and the hand-wash care.

Owners like the ceramic feel and the app control, and say it does keep coffee at the temperature they set. The common complaints are short battery life away from the coaster and the hand-wash care.
The Ember Smart Temperature-Control Mug is a 10 oz black ceramic mug that keeps coffee and other hot drinks at a chosen sipping temperature. You can set the temperature in Ember's mobile app or use the preset of 135°F.
A built-in battery holds the temperature for 80-90 minutes, depending on mug size. Pouring in hot liquid extends the battery life. For all-day use, keep the mug on its charging coaster.
An LED on the mug and the app show when the drink is ready. The app also lets you add custom drink presets. An Auto Sleep function senses when to turn the heating on and off.
