The Ember Smart is the perfect mug for those who appreciate hot drinks at just the right temperature. With a temperature range of 120°F to 145°F and up to 80 minutes of battery life, it ensures your coffee or tea stays warm when needed. Control the temperature through the Ember app, get notifications, and enjoy accuracy. Without the app, the mug automatically maintains 135°F by memorizing your preferences. Built-in sleep mode and motion sensors automatically turn the mug on and off for convenience. Scratch protection ensures durability, and an LED indicator light tells you when your beverage has reached the right temperature.
