Our take on the Ember Temperature Control 14oz Heated Smart Coffee Cup Warmer
The Ember Temperature Control Mug is a 14 oz ceramic-coated mug with a built-in battery and heating element that holds your coffee at a set temperature instead of letting it cool. You pick the temperature in the Ember app over Bluetooth, and the mug keeps it there for roughly an hour and a half on battery or all day on its charging coaster. It suits desk workers, slow sippers and anyone who lets a cup go cold. Against a plain insulated mug it adds exact control and app presets, but it costs far more, holds less than a large travel tumbler and needs charging.
- Holds a set temperature rather than just slowing heat loss
- App control with temperature presets and a name label
- Battery lasts about 1.5 hours, all day on the coaster
- 14 oz capacity suits a standard large coffee
- Ceramic-coated interior keeps the taste clean

What reviewers say
Owners like that coffee stays at the exact temperature they choose, and many call it a genuine upgrade for desk work. Complaints center on the high cost, hand washing and battery life that falls short of a full workday off the coaster.

Questions and answers
- How long does the Ember mug keep coffee hot?
- About 1.5 hours on battery at a typical drinking temperature. On the charging coaster it holds the set temperature indefinitely.
- Can I wash it in the dishwasher?
- No. The mug has electronics and a battery, so it is hand wash only. The charging coaster should be wiped clean.
- Does it need the app to work?
- The mug heats on its own, but the app sets the exact temperature and presets. Without the app you are limited to its default temperature.
- How much coffee does it hold?
- 14 oz, about the size of a large drip coffee. That is smaller than many 16 to 20 oz travel tumblers.
- Is it worth it over an insulated mug?
- If you want coffee held at a precise temperature while you work, yes. If you just want it to stay warm longer, a good insulated mug does that for far less.
- Does it work with tea and other drinks?
- Yes, it works with tea, hot chocolate and other hot drinks. The ceramic coating keeps flavors from carrying over.
