The Ember Mug 2 is a 10 oz battery-powered mug that holds coffee or tea at a temperature you set in the Ember app, keeping it there for about 1.5 hours on battery or all day on its charging coaster. It is aimed at desk workers and slow sippers who dislike reheating or drinking cold coffee. Against a plain insulated mug it trades long passive heat retention for exact, adjustable temperature control, and owners say the app and battery are the parts that decide whether it earns its place.

Owners like the exact temperature control and the coaster that keeps a mug warm through a work session. Complaints center on battery life away from the coaster, app pairing quirks, and the small capacity.
The Ember Mug 2 is a smart temperature-control mug for home or office. You set the exact drinking temperature you want, and the mug keeps your drink at that temperature. It holds 10 fl oz (295 ml).
A built-in battery maintains the temperature for 1.5 hours. A redesigned charging coaster is included.
The mug is easy to clean. It is safe to handwash and can be submerged in up to 1 meter of water.
