The Ember Mug 2 is a smart temperature control mug designed for home or office use. Unlike ordinary insulated mugs, it actively heats your beverage to a precise temperature you choose, so your coffee, tea, or hot drink stays at your perfect drinking temperature from the first sip to the last drop.

The 14 oz mug features a built-in battery that maintains your chosen temperature for up to 80 minutes on a full charge, or all day when placed on the included charging coaster. The temperature range is 120°F to 145°F (50°C to 62.5°C), and the default preset is 135°F for use right out of the box without a smartphone. Using the free Ember app for iOS and Android, you can set a precise temperature, save drink presets, personalize the mug's LED indicator color, receive notifications when your beverage reaches the perfect temperature, and use the built-in steep timer for tea.

The mug includes an Auto Sleep feature that intelligently detects when it's empty or inactive and powers down after 2 hours to conserve battery, then wakes when it senses movement or liquid. The exterior features an updated scratch-resistant coating and is rated IPX7 for submersion up to 1 meter, making it safe to hand wash. The set includes the Ember Mug 2, a charging coaster, a power adapter, and an instruction booklet. Do not microwave or place in a dishwasher.
