Is the Ember Mug 2 worth it?
A top pick in Electric Kettles on Amazon (#10 when we checked, Oct 22, 2026)
Worth it if your coffee or tea cools before you finish it and you want a reusable 10-ounce mug that maintains a chosen temperature, with app control or a simple 135°F default. It suits desk use especially well because the coaster provides warmth beyond the battery period.
Good to know: If you want a dishwasher-safe mug, microwave use, or a larger everyday cup, look for a model with those specific features.
A heated coffee mug that keeps each sip warmer
The counter is where this either works or doesn't: your drink starts hot, then sits while emails, chores, or a conversation take over. The Ember Mug 2 makes the mug itself the temperature-control point, rather than asking you to reheat the drink. Its built-in system is designed to hold hot drinks between 120°F and 145°F, with the 10-ounce version offering up to 90 minutes of heat according to the listing.
That range gives you a practical choice. Set a preferred temperature in the Ember app, or use the mug without the app at its 135°F default. The mug remembers the last setting, and the LED indicates when the drink reaches the selected temperature. So the useful change is not just a warmer cup. It is a drink that can stay within the temperature you chose while you work through it.
The coaster extends the idea for desk use. Place the mug on it for warmth beyond the battery period, while auto-sleep and motion detection reduce the need to manage the mug between sips. The trade is care: it is hand wash only, cannot go in the microwave, and comes with a coaster, adapter, and quick start guide. For someone who wants steady hot drinks and accepts that routine, the design earns its counter space.
You get a reusable 10-ounce hot-drink mug, temperature control, app notifications, a charging coaster, and a simple standalone mode. The value is strongest if it replaces repeated reheating during a work session.
Great for
- Desk workers who sip one hot drink over a longer session
- Coffee or tea drinkers who want a chosen temperature from 120°F to 145°F
- People who prefer app control but want a 135°F standalone setting
- Gift shoppers looking for a modern reusable hot-drink cup
Maybe not for you if
- You need a dishwasher-safe mug for quick cleanup
- You want to microwave your drink or reheat it in the cup
- You prefer a larger cup than the listed 10-ounce size
The Ember Mug 2 is a focused choice for coffee and tea drinkers who take their time, especially at a desk. Its temperature range, remembered setting, LED indicator, and charging coaster make the experience more controlled than a standard insulated cup. The 10-ounce size and hand-wash care are part of the fit, not minor details. Choose it when steady warmth matters more than microwave or dishwasher convenience, and it can make each long drink break feel properly timed.
Amazon shoppers rate it 4.2 out of 5 across 21,030 ratings. That is their number, not ours.
