Our take on the 14oz Ember Mug 2 Temperature Control Smart Mug
The Ember Mug 2 is a 14 oz ceramic-coated mug with a built-in battery and heating element that holds your drink at a set temperature you choose in the Ember app. It keeps coffee or tea warm for roughly 80 minutes on battery, or all day on its charging coaster. It suits desk workers, slow sippers and anyone whose coffee goes cold before they finish it. Against cheaper heated mugs, it adds app control, preset temperatures and a more polished build, but it costs far more and needs the app to unlock most settings.
- Holds a chosen temperature instead of just keeping drinks warm
- Works on battery for about 80 minutes, or all day on the coaster
- App sets exact temperature and remembers presets
- 14 oz capacity suits a full large coffee
- Ceramic-coated interior is easy to clean and doesn't taint taste

Questions and answers
- How long does the Ember Mug 2 keep a drink warm on battery?
- About 80 minutes at a moderate temperature, less at higher settings. On the charging coaster it holds temperature indefinitely.
- Does it work without the app?
- It heats to its default temperature out of the box, but changing temperature and saving presets requires the Ember app.
- Can I put it in the dishwasher?
- No. The mug has electronics in the base and must be hand washed. The lid and coaster are also not dishwasher safe.
- What is the capacity?
- 14 oz, roughly a large coffee. Ember also sells a smaller 10 oz version for shorter drinks.
- Does it keep drinks cold too?
- No. The Ember Mug 2 heats only; it does not chill drinks.
- What comes in the box?
- The mug, a charging coaster and a power adapter.
