About this item
- APP CONTROL: The Ember Smart Mug allows you to control the temperature of your hot drink from your smartphone. Connect your mug to the Ember app to determine the ideal temperature of your hot drink, and enjoy every drop exactly the way you like it. The Ember Smart Mug also works without being connected to the app. It will then automatically keep your drink at a temperature of 57°C and will remember the last temperature used: this tumbler is really the perfect gift!
- YOUR DRINK ALWAYS AT THE PERFECT TEMPERATURE: The built-in battery of the Ember Smart Mug keeps your drink warm for an hour and a half on a full charge, or all day long if you put it on the refill coaster. Choose the exact temperature of your drink from 50°C to 64.5°C.
- THE SMARTEST INTELLIGENT THERMAL MUG IN THE WORLD: The sensors of the Ember mug detect the level of the liquid and allow to control its temperature with high precision, while the convection current ensures a uniform temperature with every sip. The automatic sleep function and regular firmware updates give you an optimal experience and make this coffee flask a unique gift for men or women.
- HAND WASH ONLY: The new anti-scratch ceramic coating can be easily washed by hand. With an IPX7 waterproof rating, the Ember Mug 2 is fully submersible up to a metre deep. This is the ideal mug to enjoy your coffee bean, ground coffee, tea, cappuccino or hot chocolate at the temperature of your choice.
- EU/UK Mains Adapter: The Ember Smart Mug comes with a quick start guide, refill coaster and Type A, C and G plug adapters (supplied in a separate small box). Thanks to Ember, barely lukewarm coffees in beverage dispensers are a thing of the past!

How long does it take to charge my Ember?
Once your Ember Mug has an empty battery, place the mug on the charging coaster for approximately 2-3 hours for a full charge.
-
What happens if the mug is left empty or inactive?
The mug automatically enters sleep mode when empty or after 2 hours of inactivity and reactivates with movement or liquid detection.
-
Do I need the app for the mug to work effectively?
The Ember Mug functions well with or without the app. Without the app, it will maintain a default temperature of 57°C. With the app, the mug remembers the temperature you last set, so you don't have to open the app every time you use it.
-
Is my Ember safe to leave on the charger?
Yes! When the battery is fully charged, the charging is shut off automatically, so no battery damage will occur.
-
Is the Ember Mug easy to clean?
Yes, the mug has a scratch-resistant coating and is IPX7 rated, making it fully submersible up to 1 meter for easy hand washing ONLY. Do not use it in the dishwasher or microwave.

Customer Reviews, including Product Star Ratings, help customers to learn more about the product and decide whether it is the right product for them.
To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.

Customers appreciate the mug's temperature control features, allowing them to specify temperatures for different drinks, and find it enhances their coffee-drinking experience. Moreover, the design is stylish, and the functionality and battery life receive positive feedback. However, the charging ability and app functionality show mixed results - while some find the app good, others report it rarely works properly, and several customers mention the charging base stops working properly within months. Additionally, opinions on value for money are divided between those who find it worth the money and those who consider it expensive.

Expensive gift I use every day

- Reviewed in the United Kingdom on 6 April 2025Just fabulous. Maintains a perfect drinking temperature.
- Reviewed in the United Kingdom on 30 April 2024Lovely item, sadly the delivery was a nightmare on the product. I saw the driver throw (not drop) but throw a load of packages out of his van and the item was sadly damaged. Amazon were really good about it though. And issue was solved. Product it’s self was a great gift idea
- Reviewed in the United Kingdom on 28 January 2024I must have gotten mine in a sale because it was 70 euro which I would say is a fair price for this mug; currently, they are listed at 140 euro, it's not worth that so wait for a sale!
The iPhone app is good, the Apple Watch app doesn't seem to work though. The mug heats drinks well, although sometimes the last sips are a bit too hot. It's great for fancy coffees and it was a big reason why I started taking my morning coffee more seriously.
After 1.5 years of using it everyday, once or twice a day; the battery lasts maybe 30-40 minutes now (heating to 58c), which is still fine. The battery is non-replaceable though, so eventually this will be a paperweight; I would appreciate it if the company offered a program to return worn-out mugs for recycling in exchange for a discount on a new one - but they do not, so this will eventually be e-waste.
For now though, I expect at least another 1.5 years out of this one. I picked the black one (apparently the white ones stain) and it still looks good; there are metal ones too, but I don't see the point in spending more on a product that's disposable because of the battery. All that said, I will replace this one when it fails, but I'll wait another few years and wait for a sale.
UPDATE - December 2024:
My mug is no longer functional, it does not heat and it shows cycling LED colours when on the charger. Nothing unusual happened to cause this, so it seems to have just suffered some sort of internal failure. It was a good run, but at current Ember mug prices I will not be replacing it.

- Reviewed in the United Kingdom on 19 January 2025I was genuinely happy when I received the mug, and it worked well for several months. However, the charging base became faulty within several months, which is clearly a manufacturer issue. When I requested a repair ticket, I found that faulty pins were are one of the most common reasons for repairs.
It took a while to get it replaced, but the lady who assisted me was absolutely wonderful and incredibly fast once she took over my ticket, so I have to commend the customer service—it's fabulous. Unfortunately, the product itself is not as impressive. After several months, again the charging base developed the same issue, and one of the pins is not popping out. This is clearly a manufacturing defect or a product design flaw.
Now, out of warranty—1 year and 2 months later—the second base has the same problem. The only solution is to buy a new base. After experiencing two faulty bases within around 1 year, I don't believe this product offers good value unless you're willing to spend another £40 every six months to get new base.
Sadly, I am disappointed, as it seems to be a recurring manufacturer problem. It's concerning that they continue to sell this product, knowing that the pins are the biggest issue. I believe this product should be taken of the market & redesigned, rather than creating mass waste and waste of customers time. Therefore, I cannot recommend it. Time to stop buying products that company knows it has issues and continue to sell it. Sorry 1 star only for the potential.
- Reviewed in the United Kingdom on 28 November 2024I purchased the Ember Temperature Control Smart Mug 2 (295 ml, app-controlled, and rechargeable) a few months ago, hoping to enhance my coffee-drinking experience. At first, this smart mug exceeded my expectations in several ways.
Design and Features
The sleek and modern design of the Ember Mug 2 fits perfectly with my kitchen's aesthetic. It feels sturdy and well-made, and the 295 ml capacity is ideal for my daily coffee intake. The app control feature is particularly impressive; it allows me to set and maintain my preferred drinking temperature with ease. I appreciate the notifications that alert me when my coffee has reached the perfect temperature, ensuring every sip is as enjoyable as the first.
Performance
For the first few months, the Ember Mug 2 performed flawlessly. It kept my beverages at the exact temperature I desired, enhancing my overall coffee-drinking experience. The battery life was sufficient for my needs, and I found myself relying on this mug more than I anticipated.
Issues with the Coaster
Unfortunately, my experience took a downturn when the charging coaster started to fail within five months of use. The mug would no longer charge consistently, leading to frustration as I had come to depend on it for my daily routine. Given the premium price of this product, I was quite disappointed with this reliability issue.
Customer Service
However, I must commend Ember's customer service team for their prompt and efficient response. Upon contacting them about the issue, they quickly arranged for a replacement coaster to be sent to me. The new coaster has been working perfectly since then, restoring my confidence in the product.
Conclusion
While the Ember Temperature Control Smart Mug 2 offers an exceptional coffee-drinking experience with its innovative features and design, the issue with the coaster was a significant inconvenience. The excellent customer service I received does mitigate this drawback, but it is something potential buyers should be aware of.
In summary, if you are willing to invest in a high-end smart mug and can tolerate the possibility of needing a replacement part, the Ember Mug 2 is a fantastic addition to your morning routine. Just ensure you keep an eye on the coaster's performance and be prepared to contact customer service if needed.

Cliente AmazonReviewed in Italy on 9 November 2022
3.0 out of 5 stars Quando funziona è perfetta
Oggetto esteticamente piacevole. Purtroppo spesso non si riesce a far partire la funzione per la quale è stata progettata. Dice che la tazza è vuota quando invece è stracolma. Di conseguenza non scalda. Solo dopo innumerevoli tentativi si riesce ad accenderla. Peccato perché quando funziona è perfetta. Il modello più piccolo pare funzionare meglio. Direi che il prezzo di vendita è esageratamente elevato.
Al netto di tutto questo c’è da dire però che avevo provato altri prodotti simili e sono stati una vera delusione. Per questo si merita 3 stelle

5.0 out of 5 stars Excellent - c’est chère mais ça vaut le coup!
Pour quelqu’un qui apprécie un bon café chaud qui reste chaud, ce produit est sincèrement excellent.
Le meilleur c’est quand j’oublie que j’ai pas fini mon café, et que je retrouve la tasse et ie commence a boire et ça garde exactement la MEME chaleur d’il y a 2 heures.
Peut etre dramatique à dire mais ça m’a révolutionné le matin au travail: le plaisir et la satisfaction d’avoir mon café constamment chaud au bureau me calme.
Pour moi, cette tasse technologique vaut clairement le coût, parce que j’adore le café et j’en bois constamment, et le soir des tisanes, donc je l’utilise toute la journée et soirée. Je recommande VIVEMENT!

5.0 out of 5 stars Schönes Geschenk - hoher Preis
Ansich ein gutes Geschenk. Der Kaffe hält wirklich gut warm und das circa 2 Stunden auf höchster Stufe mit Akku und am Strom logischerweise unendlich.
Die App macht was sie soll. Die Temperatur einzustellen geht schnell und nach ein paar Minuten wird die Tasse dann auch warm.
Wichtig zu erwähnen: Die Tasse soll euren Kaffe warm halten, nicht ihn warm machen. Das kann sie sicherlich auch, habe ich allerdings nicht getestet und ist auch nicht der Sinn hinter so einer Tasse.
Der Preis ist zwar etwas hoch und für mich selber würde ich diesen Preis sicher nicht bezahlen, allerdings als Geschenk kam sie super an und die Tasse ist wirklich gut verarbeitet und macht, mit was sie geworben wird.
