- How long does the battery last?
- About 80 minutes at lower settings, less at the highest temperature. On the charging coaster it holds temperature indefinitely.
- Is it dishwasher safe?
- No. Ember says to hand wash the mug and keep the charging coaster dry.
- What temperatures can it hold?
- Three preset settings between roughly 120°F and 145°F, adjustable in the Ember app.
- Does it need the app?
- No. The three presets work on the mug itself, but the app is needed to set custom temperatures.
- What is in the box?
- The mug and its charging coaster. A power adapter is included.
- Is it worth it over a normal mug?
- If you sip slowly and want a drink to stay hot without reheating, the battery heating and coaster make it more useful than a ceramic mug. If you finish a cup quickly, a plain mug does the same job for far less.
