Understanding How an Ember Mug Works Makes It Work Better!
by Ed Harris (5 out of 5 stars)
June 20, 2017

I have had my Ember mug since November 2016 and absolutely love it, so I was curious about some of the 3 star and lower reviews. Upon reading these, it is clear that a number of purchasers (and potential purchasers) don't fully understand how the mug actually works. Ember really needs to do a much better job of explaining this (probably with a cute, animated video), but here is what is actually going on: It looks like many people think that this is a battery operated/heated mug - not an unreasonable asasumption since you do, after all, have to charge the battery. What really happens is much more interesting. Inside the walls of the mug is something that is called a Phase Changer Material (PCM). When I brew a cup of coffee in my Keurig coffee maker directly into the mug, the initial temperature is about 175 degrees with a target of 140 degrees. What the Ember mug does is to extract the heat from the coffee and store it in the PCM. In this case, the material starts out in a waxy form and liquifies as it absorbs heat. This fairly quickly cools the coffee down to the desired temperature, but in the process the PCM becomes a heat storage "battery". Once the coffee reaches 140 degrees and starts to cool, the mug senses this and extracts heat from the PCM "battery" and uses that to maintain the temperature rather than directly heating the coffee using normal battery power. If you understand this is how it works, then it is easy to understand why some people are not happy with the battery life. Basically, the hotter the initial temperature, the more storage capacity in the PCM "battery", and the longer it can maintain the coffee at the desired temperature. My coffee maker at my cabin is a smaller unit that requires me to brew the coffee into a measuring cup and pour it into the Ember mug. I also noticed that the initial temperature there is about 154 degrees. That means that the Ember mug at my cabin can't maintain my ideal coffee temperature for as long as it does at home because the PCM "battery" is not as fully charged. In fact, one day I got busy and forgot to pour the coffee into the Ember mug until it was just under 140 degrees. Normally I would expect the mug to quickly heat the coffee to the desired 140 degree temperature, but with essentially no PCM "battery" charge, it took longer than usual to get to the desired temperature and I am sure it would not have maintained the temperature for very long. So, once you understand this, you will realize that want

On my Favorite Things list
by Lynn (5 out of 5 stars)

This mug is shortlisted as one of my Favorite Things, right after my dog. It's so nice to make a cup of coffee and then get busy doing something else, and when I come back to it my coffee's still a perfect 140°, right where I left it.

Also of great importance, I was an early backer on their crowdfunding campaign, and when one of their early prototypes failed, they couldn't have been quicker to replace it. Great people!

Highly recommend!

Maybe worth $60, not $150.
by dotfaust (1 out of 5 stars)

I never review items, but people should know the cons: Not worth $150 (maybe worth $60). Heat lasts about 30 minutes and is constantly malfunctioning (very difficult to turn on and when battery is half way full it just shuts off thinking it's dead. Have to keep trying to turn it back on). The lid is impossible to clean. The lid broke within 12 weeks of purchase. Ember has yet to contact me after I've tried contacting them multiple times. Pros: Does not spill.

I love the idea of this
by Leigh M. (3 out of 5 stars)

I love the idea of this, I really really do. When it's working, it's pretty much the best thing ever. However, that being said, be aware that this thing does NOT keep beverage hot longer than about 45 minutes to an hour. For $150 I should get two hours. I hope future iterations improve upon this feature, because honestly, I like it enough to keep it, but I wouldn't buy it again, nor can I recommend it to a friend in good conscience.

Perfect temp to the very last drop!
by Northern light (5 out of 5 stars)

The bottom line
- The mug works perfectly and does what it says it will do and kept my coffee within 2 degrees of my desired temperature the whole time
- I did have an issue and I would give customer service 10 stars if I could for how they handled it

Here is the longer more detailed review

I was frustrated with my coffee being cold half way through drinking it so was intrigued when I learnt of the Ember mug. I had concerns as it was a new company and new technology. I read all the tech reviews I could find and all - yes all of the reviews on Amazon and lots of the reviews on starbucks.

I decided to wait as well let's be real new tech is going to have issues but when I saw so many positive reviews coming through I decided to try it. I was still expecting that there was a chance I would have an issue but I was comforted by buying it through amazon and by the postive reviews about their customer service and felt any issues would be dealt with satisfactorily.

Well I did have an issue and customer service was everything you want it to be. No excuses, no blame the customer, they were sincere, genuinely wanted to resolve it, incredibly responsive and personal - no cliche copy paste corporate lines.

My issue was one I had not seen anyone else comment on and Ember said they had not heard of it but were very concerned. Basically the lid was too big. You needed to be very strong to screw it on and off and after a few attempts the plastic was wearing off from the friction. We discussed it by email ( note they do not respond on weekends ) and then I shipped it back with the mug at their expense and they sent me a replacement the day after they received it.

My new mug works perfectly. I brewed my coffee into it directly this morning at 140 degree. Within 8 minutes it cooled it to my desired temp of 130 degrees and kept it there within 2 degrees for an hour until I had finished my coffee. I kept the inner lid depressed the whole time as I didn't want to keep opening and closing it but it still stayed hot as dialed in.

When I first depressed the lid it did spray 5 or 6 drops of crema out but I closed and opened it a couple of more times and it didn't repeat that. I would be a little cautious the first time and maybe put a napkin over it. It's possible it was a tad over the max fill line so it may have been user error.

After it kept my coffee hot at 130 degrees OFF the charger plate btw the battery was at 69%.

Other considerations

The mug has pleasing aesthetics. Quite Apple like. It's simple and graceful. Has a good weight and a pleasing tactile feel. The charger is slim and simple in style too.

The rim is thin. I dislike drinking from thick rimmed mugs so was pleased with this detail.

The 360 degree opening ring to drink out of is also a positive. You don't have to line up with a hole every time you take a sip.

The lid doesn't leak! That's a great feature combined with a quick and easy way to drink from it by just pressing down on the centre ring of the lid. I've had soooo many travel mugs leak I had given up on them until Ember came along. It was a big selling feature for me.

There is nothing this mug didn't do that it said it would and it did everything it said it would.

You may wish it did more but it's only fair to measure it on what it promises and if you want to get cutting edge technology then realistically be prepared to have an issue but you should demand excellent customer service to rectify and they certainly provide that.

A measure of a company is how well they manage a problem. Two thumbs up to Ember support team!

If you want to enjoy every drop of your coffee at the right temperature without gulping it down all at once I recommend this mug. It's just made my mornings a whole lot more pleasant 😊

I am attaching a pic of how my first lid fit ( it was too big and sat too high in the mug ) and how my new lid fits - obviously this is before you screw then in place so if your lid seems to fit too tightly this will give you some perspective for comparison.

Perfect tempurature coffee or tea any time at home, 2 hours or less on the go
by Douglas Birk (4 out of 5 stars)
January 28, 2018

I first bought the Ember Ceramic Mug for my wife (and really for me). I was simply tired of being the "honey, my coffee is cold" person. The Ceramic Mug does a great job of being the "keep my coffee or other hot beverage my perfect temp while I'm at home" product.

Turns out the Travel Mug is better at that too... It's at its best while I'm at home. Keeps my coffee at exactly 134 degrees for as long as I want while at home.

You see, it's all about the maximum two hours (really 1:50) it can maintain that temp while away from its powered coaster.

Now... don't get me wrong, I am really enjoying it. I never have to burn my mouth again to see that I need to let my coffee cool a little longer nor miss that perfect sip of 134 degrees.

Every sip is that perfect temp, while at home.

Ember... PLEASE create a USB adapter so I can at least keep it going longer during my commute...

Keeps coffee warm for 10 min before battery dies.
by Urooj Imtiaz (1 out of 5 stars)

Absolutely garbage product for a premium price. I tried to jump in at the funding stage and then bought one when they started selling at Starbucks stores before providing one to those who funded through indiegogo. Eventually the moment of truth came and the both tumblers failed miserably. They don't even keep coffee worm for 30 min. Especially during winter months when you need them most. The battery just drains like water through a cup with a hole in it. Would never recommend anyone paying plus $100 on such a product. If you need something fancy, there are better Chinese tumblers for less then half the price that also have an app. I have eventually stopped using them 1 month after my purchase...

Tea (Life) Changing!
by Jason Kudlock (5 out of 5 stars)
March 23, 2018

I recently purchased the Ember temperature control mug because unlike my wife, I can't drink my tea at 1,000 degrees Fahrenheit. I always have to sit and wait for my tea to cool down to a temperature that won't blister the inside of my mouth, and by the time I remember I was letting it cool down, it's too cold to drink, leaving me with lukewarm, unsatisfying tea. When I first heard of the Ember mug I was skeptical, but I finally gave in, and after a couple days of use, I'm not sure how I started my mornings or finished off my afternoons without Ember. It keeps my tea at the precise temperature of 117 degrees, right where I like it, for the hour plus I lollygag around drinking it between emails and business calls. It's such a simple, yet brilliant idea, I'm surprised it didn't come along much sooner than it did. The only problem is trying to hide it from the wife before she can use it to keep her tea at a smoldering 1000 degrees, but if she does, the app allows me to keep my preferences and presets customized to my liking and hers to her liking. Two thumbs up!

Lasts less than an hour
by Karen Hart (1 out of 5 stars)
February 1, 2019

I need to disagree with Ed Harris who posted the review about how the mug works. I actually bought my mug after reading his review because I have an "instahot" water faucet that dispenses water that is almost boiling. I thought I would fill my mug with this boiling water before I made my coffee, (like I used to do with my Yeti coffee cup), and then I would not have the battery life problem that other reviewers have had. Unfortunately, it does not make a difference if I warm it first or not. If Ed Harris was correct in his review about the energy cell storing heat, then I should see a marked difference in battery life by filling it with hot water first. My battery only lasts about 45 - 60 minutes, which means that I should have saved my money and stuck to my Yeti. I wanted to love this product. It is really disappointing that there a so many bad reviews on the battery life over such a long period of time, and it seems that Ember doesn't care, since it has been so long and they are not doing anything to improve upon the product. Save your money or maybe try a competitor.

Leaks - about as useful as a chocolate teapot
by Rachel Quin (1 out of 5 stars)

Good idea, but one of the main reasons I purchased the product is because it's supposed to be completely leak-proof. Sadly despite following instructions to a tee and filling below the max line, liquid pours out of the sides of my cup.

Have contacted customer service who claim they will not support customers outside of the US (why allow international shipping through Amazon then?) - will update my review if a sensible resolution is achieved. Until then, a massive waste of money, I would have been better buying a thermos.
*UPDATE: International customers beware, I was quoted an exorbitant shipping cost to ship a new lid to replaced my faulty one, not worth the money. Looks like I'm stuck with an expensive leaky cup. Merry Christmas to me!*
