Customer Ratings & Reviews

Great product! Keeps my coffee hot and fresh, and very easy to control with the app!

The Ember Smart mugs aim to solve a small inconvenience that many coffee and tea drinkers often encounter -- that the drinks just don’t stay hot enough from the first sip to the last. This latest model, dubbed the Ember Cup, has the smallest capacity in their lineup at 6 oz, but if you’re not a “big mug” coffee or tea drinker, it just might be the perfect size for your needs. The cup itself has a minimalist design: a smooth, matte finish, no handle, and inconspicuous branding with a single status LED at the bottom. The cup sits 3.25” tall with a 3” diameter, and 2” interior depth. The reason why the cup is so much shallower than the overall height is due to the electronics and re-chargeable Li-ion battery packed into the base. So while the cup may look larger from the exterior, it still only holds 6 oz. On the bottom of the cup is a single power button in the center, and around it are two gold metal ring charging contacts. When placed on the accompanying charging saucer/base, two small pins will touch the rings no matter how the cup is oriented, so precise placement is not needed. Since charging is not accomplished through induction, you won’t be able to charge the mug with other wireless charging pads like a Qi charger, however, additional charging bases can be purchased separately and are compatible with all Ember mug models if you want to have multiple places where you can set your mug down to charge. The coaster bases use a standard barrel-style plug with wall adapter and need to be plugged into an outlet. A full charge takes about 2 - 3 hours. The way the device functions is pretty straightforward; power it on, fill it with your hot beverage of choice, and a heating element in the base keeps it at a temperature of your choosing between 120°F to 145°F (or 50°C - 62.5°C). If the drink is hotter than the set temperature, the cup simply allows the drink to cool until it reaches the target temp. When it falls below that temperature, the heating element kicks in, and the LED will pulse white and remains a solid white while holding at the target temperature. It can keep your drink hot for up to 90 minutes on battery power, perfect if you want to take it when you roam, but be cautious of spills as it has no lid/cover. If you set the cup on its charging base, the temperature can be held constant indefinitely, though there is a 2-hour inactivity auto-shutoff feature that can be reset by simply picking up the mug. Note that the battery won’t increase in charge if the mug is actively maintaining temperature on the charging coaster. It’ll only charge when the cup is empty or is powered off by pressing and holding the power button for 3 seconds. Out-of-the-box the default holding temperature is 135°F, which I found to be a pleasantly hot and drinkable temperature for café au lait and cappuccino. The reasoning for not allowing higher temperatures is that this can degrade the flavor of a beverage over time, curdle drinks containing milk, and is a potential scald risk as well. To change the temperature setting, you’ll need to pair the mug to a mobile device via Bluetooth and install the Ember app, which requires you to register for an account. To enter pairing mode, simply press and hold the power button for 5 seconds. In the app you can also customize whether or not to receive push notifications when your beverage has reached the set temperature, change the temperature units to Celsius, and choose a custom color for the status LED. Your LED color will illuminate upon powering on/off and each time you pick up the mug, as it has a built-in accelerometer to detect motion and help multi-mug households identify individual mugs quickly and easily. When the cup is empty, it’ll automatically enter sleep mode and will not actively heat, though it will remain paired with a mobile device. Keep in mind this cup is not designed to “heat up” cold drinks quickly, as the heating element delivers only gentle warming and increases the beverage’s temperature about 1 degree every 10 seconds. In fact, if the temperature of its contents is under 100°F, the heating element will remain off, unless you manually change the holding temperature; changing this value will engage the heating element even if your drink is cold, but not if the mug is empty. Pouring in any drink that is at least luke warm, above 100°F, will automatically start the heating element if the cup is on and below the target temperature. One quirk I found is that if the cup is placed onto the charging base within about 15 seconds of powering it off, it will automatically power on again and connect to the most recently paired mobile device, if it’s in range. While it should still power off after 2 hours of inactivity, I nonetheless found this behavior a bit strange. The mug is neither microwave nor dishwasher safe, so hand washing with a soft sponge is the recommended cleaning method. You should also completely dry the mug before placing it on the charging base as the gold contacts and rings may be corroded by liquid, which can in turn cause charging issues. It seems a bit unexpected that the coaster base would not be waterproof though, since they're usually meant to catch spills and drips. You also won’t want to use metal utensils in the Ember, as this can damage the finish, so you can pre-mix your drinks before pouring into the Ember or use wooden or plastic spoons instead. Overall, the Ember Cup does the job it’s intended to and keeps a small amount of my hot beverages precisely at my desired drinking temperature, whether that’s tea, coffee, espresso, mulled wine, a hot toddy, etc. The battery life is decently long, and the charging base can extend that to last the whole day if need be. Its care requires a little extra mindfulness to keep it pristine, but I suppose that’s the trade-off for a relatively niche, "nice-to-have," luxury gadget.

The Ember mug does what it’s meant to do well, but requires some retraining and keeping your cup in one location (not that you couldn’t travel with it, just too cumbersome for me). And it’s pricey for being a cup. But if you are one to sip and enjoy a hot beverage over a longer period of time, this is something you should look at. I haven’t seen anything else like it, so if you’re reading this and thinking about getting it, you’re likely already intrigued. But there are a few practical things I think one should know when considering purchasing this product. IN THE BOX Inside you’ll find the Ember cup, a charging “saucer,” instruction book, and wall charger. The charging cable is proprietary, at least, it’s not USB-C, so you have to use the included charger. The cable should be long enough for most people but with my setup in my office, I wish I had about an extra foot. SETTING UP There are some stickers on the cup that tell you to charge fully before using. First thing, plug in the saucer to the wall outlet, then place the cup on the saucer to charge. The charging is similar to any wireless charging setup; there’s gold rings on the bottom of the cup that make contact with two gold pins in the saucer that charges it. There’s a light on the bottom of the cup that blinks red when it’s charging and glows green when it’s fully charged. From there you download the Ember app. I’m one to loathe having dozens of unnecessary apps on my phone (at least apps I don’t use frequently) but nonetheless, this is an app you arguable don’t need to access once you set it up. Once the app is downloaded and cup is charged, you hold the power button on the bottom of it until the aforementioned light blinks blue to tell you it’s in pairing mode. From there, the app should find it pretty quickly. Once it’s connected, you’re all set up. APP The app is basic, there’s not much for it to do. You can slide the temperature bar on the app which tells the cup what to hold the temperature of your beverage at. There’s also presets for tea, coffee, etc. You can even make your own presets. I noticed a timer for steeping your tea, but I didn’t use that (I always “eye ball” the length of time to steep my tea). The temperature differences between the coffee preset and green/black teas are just several degrees. To me personally, that temperature difference doesn’t warrant me opening the app each and every time I pour something in it. The app will give you a notification when your drink hits the optimum level (you can disable this). USE Pretty self explanatory, as long as your cup is charged, once you pour liquid in it, it will begin warming it up to the right temperature. The light blinks white on the cup to let you know it’s not quite to the optimal temperature yet and it’s working on it. It can detect if it’s empty and if so, it won't heat up. The cup itself gets slightly warm on the outside, but never does it feel too hot to hold. It’s pretty insulated. The battery purportedly lasts for 2.5 hours. I found this to be pretty accurate. I’ve left the cup off the charging saucer for a few days and used it without issue. But I keep the saucer near my desk (I use mine at work) so I’m always able to simply leave it on the charger. By the time I bring my thermos of coffee into work and pour it into the cup, the temperature is usually in the 118 degrees range. The preset for coffee temp is about 134. I’d say it takes about 5 minutes to bring the temperature up 15-16 degrees which isn’t too bad. It’s not as if I don’t drink it as it’s heating up. As someone who brings in what seems to be a half cup of coffee to work, I really do enjoy the ability to keep it hot all morning. Otherwise, my last sips are almost cold coffee. So for me, this Ember cup is nice to have. As I said, you don’t really need to open the app when you use the cup outside of the initial setup. So I don’t want to give the impression you’re constantly having to open your phone and the app to use the cup. QUIRKS A couple things to mention during my experience. It’s not necessarily advertised in the box, but if you Google search it you can easily figure this out, but it does not heat cold liquids to hot. So don’t expect to pour in a cold cup of coffee or tea and expect it to heat it. If the liquid is too cold, the cup will think it’s empty. Think of this cup as simply maintaining hot temperatures. I don’t know the effective range of the temperatures it will maintain, but something to keep in mind. The charging saucer can be finicky. There’s two gold pins at the bottom. There’s a sticker warning to not let it get wet. Easy enough. But I found the cup failing to charge at one point (after only having it a few days). I reset the cup and repaired it and it didn’t work. But at some point, it started charging again. I don’t know what happened, but it was a tad bit concerning to me when thinking about the device’s longevity. CONCLUSIONS Other than my last two observations, I must say, this cup works as intended and works well. Of course this particular model only holds 6 ounces, so it’s a bit small. But that doesn’t bother me. It’s clearly a luxury item, but if drinking hot liquids over a long period of time (when they would otherwise get cold) is important to you, I would definitely recommend this Ember cup - or any of them for that matter.

As a coffee drinker, I have done just about everything to keep my favorite morning beverage at a comfortable drinking temperature while I enjoy it. I was thrilled when I heard about Ember products and couldn’t wait to try them. This smaller mug is perfect for stronger beverages or when you just want a ‘touch’ of something. For example, I like having a cup of coffee in the morning, but in the afternoon, I prefer to have some hot tea. That said, I don’t like to have a large cup of tea. So, this 6oz mug is perfect for that afternoon tea time. Set up of the mug is easy. There is no assembly required and aside from plugging the charging dock into power, the user only needs to connect the mug to the app. The user manual is included as a printed booklet with the mug, but all the languages are not separated. Each step has every language option included with that step. For me, that makes it harder to read. The English instructions are highlighted in orange, but I think it would be easier if each language was separated. I have an iPhone and so the connection to the app was pretty much flawless. I used the original Ember mug a few years back and at the time, the app connection wasn’t very good. It worked, but not as smoothly as it does now. There is also an Apple Watch app that allows you to monitor and change your preferred temperature. To pair the mug to the app, you press/hold the button on the bottom of the mug until you see a blinking LED below the Ember logo. The app should recognize the connection via Bluetooth very quickly. One thing I want to mention is that the app is non-specific about device pairing. It will ask you what product you have and give you three options - the mug, travel mug, or travel mug 2. For a moment I wondered if I had selected the correct app and then I selected mug to see what would happen. It was the right selection, but it would be nice if either the specific products were listed or a dialogue box appeared letting the user know that it isn’t product-specific. This isn’t a dealbreaker for me, but it would make the user experience better. From here, you just set up your Ember account and make sure the firmware is updated. Then you have the option to set your preferences for the device. You can change the color of the LED and your preferred drink temperature as well as if you want the temperature reported in Fahrenheit or Celsius. I think it only took me about 5 minutes to get everything set up - from box to drinking. The mug did have a charge out of the box (about 30%) but I would recommend charging it before use. You can leave the mug on its charging dock while you are enjoying your beverage but you don’t have to for it do its work. As I mentioned I planned on using this smaller mug for my afternoon tea. So, to test how well the mug works to regulate the temperature, I made myself a cup of tea. I have a hot pot to heat water for coffee and tea so I set that to make some hot water and got my tea leaves set in my steeper. I poured the water into the mug and by the time I walked back to my desk, the app had already registered that there was liquid in the mug and that it was 191º. My preferred temperature is set at 135º, which is the default for the mug out of the box. The app had already started to reduce the temperature of the tea and after about 10 minutes, the drink had been reduced to the 135º setting. I took a drink at that temp and decided it was a good average warm temperature for tea. Next, I grabbed an ice cube and dropped it into the mug. The ice cube reduced the temperature to 106º. Once the temperature had stopped dropping, the Ember mug began working to bring the temperature back up to 135º. It only took about 5 minutes for it to raise the temp to 135º. This was very impressive to me. After about 30 minutes of working with the mug, I got a notification that the battery was low (3%), so I set it on its charging dock. I enjoy using this mug and think that if you drink warm drinks regularly, it’s a great investment. Pros: Packaging is subtle, but easily identified App-enabled Works when not on the charger Quick connection to the app cools and warms drink to set temp efficiently Watch app Cons: Manual is not separated by language (English is highlighted in orange). This makes it harder to read. The specific device is not available in the app.

Ember has finally come out with the perfect size for those that enjoy espresso based drinks (think cappuccinos, lattes, macchiatos, cortados, and flat whites). Where the Ember Mug holds 10oz of coffee, this Ember Cup holds 6oz. At 3.3 inches tall and in diameter, it is a smaller cup size. Keep the size in mind for when you want to switch it out to a regular cup of Joe - you may need to get the mug! Unboxing was fairly straight forward, you get the cup, the charging coaster, charger cable, and informative manuals/instructions. The cup is a beautiful matte black with a matching base. It really looks great on my desk since I am going for more of a minimalistic setup. Once charged, you download and boot up the app from your phone's webstore. The app can really use some improvements. UI is a bit lackluster and controls could definitely be better placed. You think you would want to see the battery status without having to go into the settings. This is the only reason I take away one star BUT you do not need the app to have it stay at the default 135 degree temperature. The battery life has a reported use time of 1.5 hours, I got pretty close but I think external environment temperatures varied a lot. Your mileage will vary with temperature settings and battery use. This makes a great gift for the espresso lover in your life. I already have plans to purchase a few for family members and friends.

EMBER - TEMPERATURE CONTROL SMART MUG - 6 OZ MODEL:CM210600US Best Buy Tech Insider Network NICE ENDULGENT HEATED SMART MUG FROM THE FUTURE OVERALL I can’t help but thinking of various SI-FI movies as I download a firmware update to my coffee mug! At first, I thought what a silly idea, I already have an old-fashioned coffee warmer on my desk, that , if we are hones, really only works in for the last centimeter of coffee and otherwise just seems to heat up the outside of my mug making it too hot to hold. Along comes the EMBER - SMART MUG to change my mind about how I enjoy my morning drinks. I like to savor my morning tea and coffee as I ease into the morning. Which usually means after a few minutes I’m drinking tepid liquid as best, even with my electric warmer. Now with the EMBER - SMART MUG it is always as hot (or hotter) than the moment it came out of the coffee/tea/espresso maker. We have 2 coffee makers one with decaf and one with regular beans. The one with regular beans makes a better brew, but its temp is a little low. Now with the EMBER - SMART MUG it is heated to the perfect temp. My wife likes her coffee as hot as possible, while I like it a few degrees cooler. With the EMBER - SMART MUG app we can adjust this with a single button press. SETUP I was a little worried with all the stickers, don’t microwave, don’t get the contacts wet, etc. Nevertheless, the setup was one of the better app installations in a while. Just put the EMBER - SMART MUG into pairing mode (I still can’t say that with a straight face), and the app finds it. Then you can control your temp, AND LED EFFECT COLOR! USAGE Somehow it magically knows when you have liquid in there and turns itself on. Then it does a fantastic job regulating the temperature until the liquid is gone. Next you rinse it out make sure it is dry and put it back on the base to recharge. It does take a long time to fully recharge (hours), and I wish it used USB-C chargers for example, instead of another proprietary charger. Yes, this version is only 6 oz, but that is OK as that is just about the size of output on the coffee settings from my espresso machines. I also look forward to having my espressos with the EMBER - SMART MUG which previously got cool too quickly. If you take cream or foam with your drinks, you will have a very small drink indeed. I also would have liked a lighter color. The mug is so dark it is like looking into a black hole and you can’t tell if you have any liquid left in the mug. Owing to the overall weight it always feels full. SUMMARY I like the EMBER - SMART MUG and make no mistakes, that this is a pure luxury item. But if, like me, you like to take your time to enjoy your hot drinks, then it is the perfect gift for yourself or others. I can already see us saving up enough Points to get another one (his/hers) before long.

I’ve heard of Ember cups for some time but never felt compelled to buy one because I quit drinking coffee for awhile during Covid. I found I added way too much sugar and creamer and found it was just too many extra calories. But recently, I started drinking more espresso based drinks like Cappuccinos and Macchiatos or just shots of espresso with no added sugar, just frothed or flat milk, so this 6oz Ember was perfect. I’ll start by saying 6oz. just isn’t as big as you think. Even though I got this just for Espresso drinks I wish it was 2oz bigger. The cup is comfortable to hold but heavier than expected and also holds much less liquid than you would think because the heating elements, batteries and electronics are a good 1/3rd of the total height of the cup. With a double shot of espresso roughly 3oz. the other 3oz filled to the brim with cream or frothed milk is just barely big enough for your typical cappuccino or macchiato. I also didn’t love the huge AC adapter, it’s generic, large and just not very attractive. It’s also a pin-type, I would’ve much rather seen a USB-C plug on the charging coaster and either USB-C or A that connects to a small wall wart. This would make it possible to plug into the wall or into any USB port so you can just move the coaster and not have to also take the AC adapter. All of that said, the Ember itself works amazingly well, especially if you don’t want to steam or froth milk. I sometimes just add a splash of cold creamer or milk to my drinks and that obviously drops the temps of the drink. With Ember, you just set the temp in the App (really the only thing the app is used for) and it rather quickly warms the drink back up. My espresso came out at 147F, after adding creamer it dropped to 132F but within 7-8 minutes it was back up to 145F. The downside is doing that used about 1/4 the battery level, but I only drink 1 espresso a day and the Ember definitely made the drink more enjoyable as temps stayed hot throughout the drink. Typically temps drop immediately and faster the less liquid that is leftover. Overall very happy with this Ember, but I do wish I got a larger size for more flexibility on drink types.

I tend to drink my coffee quickly, but this cup is perfect for my wife who prefers to enjoy her coffee as she works. The small size works perfectly with the small setting on our coffee make (Keurig). The cup was pretty much what I was expecting, but I was surprised at how useful the app is. I am even thinking about getting another one for my daughter who enjoys tea, since the app has a tea timer and can tell you when your tea/coffee has reached the set temperature. Pros - Nice looking, with quality feel - Customizable LED for indicating status and battery level - Temperature setting is accurate to just a few degrees and the cup even knows when it is empty - Tested 90-minute battery life set at 137 degrees (more than enough for this size cup) - Great app with useful notifications, temperature info, preset temperatures, tea timer, battery level and even a few recipes - Easy to clean (no dishwasher) Things to consider - The charging base, which in most pictures is shown being used like a coaster with a full cup, can’t get wet! I was hoping it was inductive but it is just a set of contacts that are designed to touch a set of rings on the bottom of the cup. It hasn’t happened yet, but I could easily see a spill being the end for this cup if the contacts aren't well sealed. - Ember does offer larger cups, but this one is small. I think the size you get comes down to personal preference, but this works well for people who sip their coffee or tea. - There is no handle, the cup is smooth with a slight curve and has decent weight for its size. The surface has a nice texture and it fits well in your hand, but it still requires care in the way you pick it up/hold it so you don’t drop it. - This is my fault, but I have filled it and forgot to turn it on before. This situation makes the bottom mounted power button seem a little inconvenient.

I don’t need to tell anyone how frustrating it is to make a hot cup of coffee in the morning, getting distracted by the chaos of the day, only to return to a cold cup five minutes later. I’m sorry but reheating it in the microwave just isn’t the same as a fresh cup. The Ember coffee mug relieves the frustration using technology that can keep your cup of coffee at the perfect temperature for hours. The cup and charging cradle were very simple to set up and sync with the Ember app via your smartphone or tablet’s Bluetooth connection. Once the cup is synced in the app with a simple push of a button on the bottom of the cup, you can customize how hot you would like your coffee maintained at, up to 145 degrees. The Ember cup can keep your drink hot between 1-2 hours off of the charging cradle or constantly hot for hours sitting on the cradle. After using the Ember cup for a few days, I could taste the difference between a cup of coffee that was reheated in the microwave and one that maintained its temperature in the Ember cup. This is a great product for those of you who, like me, get too busy in the mornings, or any time of the day, and would love to just enjoy that hot cup of coffee when it’s convenient for you.

From your first sip to your last, the Ember Smart Mug will keep any drink of your choice the perfect temperature. The Ember smart mug is able to maintain the temperature of your favorite hot beverage for about 1.5 hours on the built-in battery and you can even run it all day with the provided charging coaster. This smart mug holds about 6 oz. of favorite hot beverage so it is ideal for espresso, cappuccinos, or even coffee. To start off you will need to download the Ember app and pair your mug to your phone. The pairing process is very simple as well. You will need to hold down the power button on the bottom of the mug until it starts flash blue and then your phone should be able to pick it up and that is pretty much it. At this point you can start using your smart mug. The application allows you to do a little bit of customization such as choosing the color of your light and adjust the brightness. You will need to use the application to adjust the temperature of your beverage anywhere between 120 to 145 degrees and will send your phone a notification once the temperature has been reached and provide you with the battery status. One thing to keep in mind is that ***THIS PRODUCT IS NOT DISHWASHER SAFE***, this is handwash only and is submersible up to under one meter of water but I would not recommend that you try that. Overall, I am very impressed with the Ember Smart Mug. I have been using this now for a few days and I honestly have no complaints, it’s a solid product, it does what it is made to do all while looking amazing in a matte black finish.

I really think this is a great idea for drinkers of warm to hot beverages. Even though this product came to be becaause the inventer couldn't eat hie scrambled eggs quick enough. Brilliant man, and kudos to him for this. However, I have a problem with the fact that this coffe mug is only 6 ounces and it cost a bill. I understand that this is new technology and new tech isn't cheap. But again, it's only 6 ounces. With that being said, the tech is pretty sweet. I am able to kep my coffee or tea at the temperaature I want for long eriods of time. By that, I mean, the mug alone, lasts up to an hour and a half after being fully charged on the coaster. And infinitely as long as it's on the coaster. The controls are on the Ember app and is relatively simle to use, soo that's great.You can change the color of the battery light to your favorite color or to match your dacor. Again, that's a cool thing. In the box you have everthing you need to start drinking your beverage. But you have to charge it completely the first time. And that's goingg to take a few hours. But once that's done and your app is up and running. Pair it up to your mug and you're on your way.The problem as i said, is the mug is only 6 ounces. And most people I know let's their coffe to cool a little before drinking it. The temperature stats at 135 degrees and goes up. The only time this could be handy, to me, is when it's cold inside thee office, because that bring's up my second point. There is not lid, so there isn't any protection from fallind objects. Meaning this can't be useed outside. And again, 6 ounces. That shouldn't last long at all and certainly not long enough to warrant keeping your drink hot. So I feel that this is not a good purchase. It's great idea and good start. This would make for a neat Father's Day gift, because I'm pretty sure Dad doesn't have anything like this. But even as a gift, it's simply over-priced. I can't recommend this to anyone, really. There's no one that I know that could benifit from this mug. In the end, I feel you should pass on this unless you absolutely must give a gift that Dad doesn't have. 6 OZs ain't worth $100.

To be honest, the wife and I use this more than either of us thought we would. Both being morning coffee drinkers (she prefers coffee, I prefer Espresso), we have an every-other-day custody agreement with visiting rights being granted on an as needed basis for the occasional evening/weekend use. Unpacking was simple. The box was a quick Benchmade knife slice to remove outer film, then a couple simple steps to get into hardware. Inside you'll find the cup (of course), the charger, power supply, user guide and an Ember "sticker/decal" deck in case you like it so much you want to brag? Set up was as expected, super simple. Plug in the charger to base, plug other end into wall outlet and place cup on charger. We set it up, ran about 3 hours or so of errands and it was fully charged when we returned. The "power" button (also the button to connect to app) is on the bottom center of cup. The app is expectedly simple. You can set the default preferred temperature, status and set the default LED color. She wanted pink, I wanted blue so we settled on purple. We both like our drinks hot so we agreed to default at 145. Battery life when not on charger is listed at 1.5 hours. The longest I tested was maybe 30 minutes and it was still at 145. It is also advertised as keeping hot all day long while on charger but I cannot confirm/deny since I never tested ***IMPORTANT NOTE​​​**** *Hand-wash only *Make sure charge points on cup bottom are thoroughly dry BEFORE placing on charger *Cup is NOT microwavable End of the day, cool cup and a handy gadget. I would (and have) recommended to friends.

I'm a coffee and tea drinker. Though I've scaled back my volume, I am cherish my one or two cups of meticulously made caffeine beverages each day. For me, these are meant to be warm-to-hot for optimal flavor. Life gets in the way, and it's a heartbreak when I return to my cup and it's cold. I was really excited to obtain an Ember after all this time. It's a beautiful product. Elegant, with a nice weight and shape. It, like any good beverage container should, feels really nice in your hands. The charging base is simple and elegant. I'd like it to truly function as a saucer, but you are discouraged from letting it get wet. I'm guessing that's due to the charging contacts being exposed. Perhaps induction will be in the next version... I'll get my other gripe out of the way - if you drink a contemporary amount of coffee, that is, more than 6 ounces, this is too small and questionable in value. You probably get that first 4-6 ounces down fast and the value is keeping the other 4, 6, 8 warm. That said, if you want to precisely control the temperature of a coffee or tea concoction (latte, espresso, macchiato), this is the product for you. Cool things - there's an app that tells you if your cup is empty, and it let's you set that precise temperature for your liquid pleasure. You can create presets for different types of drinks. Say you like your black tea at 135 degrees, and your latte at 145, just create it once and select it later. Nice. The app advises of the charging level from 0-100% and it can send you notifications as well. Minor bonus, you can select the color of the status LED. Finally, the app, if you elect to do so, will provide the approximate caffeine intake and share it with the Apple Health App. I'm a data geek, so I love this. Revisiting the review title, I should have selected a larger model to enjoy the benefits appropriate to my intake levels. Otherwise, this is a nice product.

I have been super curious about the Ember cup since they first started releasing them. I go back and forth between drinking hot and iced coffee. When I drink iced coffee and seem to gulp it down rather swiftly, but hot I normally finish my fist cup quickly but take my time with the second. So much so that I normally end up having to toss out the second one because it gets too cold. The idea of keeping my coffee the temperature I wanted was very intriguing. Fist off the presentation when unboxing this is very nice, and instructions are straightforward on hot to get started. You get a few warning labels, things you might expect when using electronic devices around liquids; hand wash the cup only and keep the sensors on the cup and coaster dry to keep from corroding, as well as a reminder that you shouldn’t microwave the cup since it is electronic. After all the initial charging and setup within the Ember app I was pleasantly surprised by a feature that I was not expecting. The Ember app has a feature called, Ember x Health that connects to Apple’s Health app on the iPhone. The idea is that the app can auto log your caffeine consumption and compare that to your heart rate and sleep patterns if you are using an Apple Watch to track that information. I love this extra layer of insight into how caffeine consumption is affecting my general health. The million-dollar question here is, does this cup manage to maintain the temperature you are looking from your perfect cup of Joe. After a few days of using this the answer is absolutely. Now the cup itself has a battery that can maintain your temperature for about an hour and a half, but the great thing is that if you just set it on the coaster/charging station it can keep that temperature all day. At first, I was going to keep the coaster near my coffee station, but I have decided to move it to my desk since that is normally where I enjoy my coffee in the morning. Another bonus aside from the Apple Health integration is that I normally wait a bit for my coffee to cool when I pour a fresh cup. The app and status light will show you when it has reached your target temperature. The status light does this slow pulsating effect when your temperature is moving towards its desired goal, and then stays steady when it has reached the correct temp. Again, a nice little feature that I really enjoy. After a few days of using this Ember cup I can easily recommend it to any avid coffee drinker. Keeping your coffee at your preferred temp is a great feature that I wish I had started using much sooner. Maybe you gulp down your coffee faster than it can cool, then I think the Apple Health integration might be something you will enjoy. It automatically logging your coffee consumption should be interesting to see your patterns and how it might be affecting your heart rate or sleep patterns. This would definitely make a great gift for your techie coffee drinkers.

I don't see a better way to keep your coffee hot like with this Ember cup. This 6oz cup will keep your coffee at your desired temperature for a long time. This cup will not only keep your coffee hot, you can actually adjust how hot you want it using the Ember app. After using it a couple of times this cup is smart enough to remember your desired temperature so you don't have to keep opening the app every time. This cup is rechargeable. I will say it will last about an hour total. I turn the cup on for about 15 minutes per drink a few times a day, three to four times to be exact. The cup is very nicely constructed and feels just like any other regular cup in the hand. Even though it has a rechargeable battery and electronics components it doesn't feel much heavier. Setting it up with the app was super easy and the best part is that it doesn't require you to create an account. At the time I wrote this review this cup was not listed in the app, so I used the Ember mug to configure it. It worked perfectly. Overall if you love to drink your coffee hot and want to keep it hot until you finish it, this cup will be a right choice.

TLDR: (that’s Too Long, Didn’t Read) If the size of this smaller Ember Cup meets your hot-beverage needs, you’ll find all of the awesome features of the larger Ember Mugs but in a smaller handle-less size. Pros: * Attractive design without a handle. * Easy to use. * Comfortable to hold. * Good enough battery life for between-saucer drinking. * Same great features and app as the larger Ember Mugs. Cons: * Same issue as all other Ember Mugs that the bottom should be air-dried before being placed back on the charging saucer. Details - Setup: Plug the charging saucer in with the provided AC adapter. I’m not sure why they didn’t go with a USB-based charger, but everything works, so it’s not really and issue. If the Cup isn’t already on, press center of the bottom to turn it on and put it in pairing mode. Then place the Cup on the saucer to charge up while you set up the app. After installing the Ember app, just open the app and tap “Pair new device.” The app will find and pair with the cup so you don’t need to first pair via Bluetooth (at least on a current iPhone. Every Ember Mug has a status LED on the front and you can choose that light’s color to more easily identify your Mug from someone else’s of the same model. The app will tell you the Cup’s battery level and whether there are any firmware updates (yeah, for your coffee cup!). If you have an Apple Watch, you can also install the free app for that and see your Cup’s current temperature without reaching for your phone. That’s basically it for setup. You can also choose favorite settings for your hot beverages; like 135F for Coffee or 150F for Tea, etc… Details - Typical Usage: While there is added flexibility and customization when connected to the phone or watch app, you can also easily use the Cup without the app. Pour your favorite hot beverage and the Cup will turn on and keep it at 135F by default. Take it off the charging coaster for up to 90 minutes to keep your drink hot while you roam. When you’ve savored your last sip, the Cup turns off the heater. You can buy extra charging coasters to have them available wherever you typically park yourself and drink, but the Cup is completely compatible with the saucers for all other Ember Mugs. When you’ve finished your drink, just hand wash it in the sink. It’s completely waterproof for hand washing but I wouldn’t put it in the dishwasher. One thing to note is that the bottom of the Cup (and the Mugs) has metal contacts for the charging and a rubber non-slip pad. While this all water-safe, there are nooks and crannies that always seem to trap a bit of water no matter how well you dry it. If you put your freshly washed and dried Cup on the charging coaster right away, some of that trapped water will leach out and moisten the charging area leaving a wet ring between the Cup and the Saucer. This won’t cause damage, but I’ve gotten in the habit of placing my washed mug upside-down on the coaster for an hour or so to air-dry before flipping it right-side up to charge again. As you can see from the attached photos, this new Ember Cup is basically a smaller version of their other Mugs. It holds about 6oz whereas the “regular” Mug holds 10oz and the larger Mug holds 14oz. There is no handle on this one, but I like the feeling of grabbing the cup by the sides. Even with freshly-brewed coffee or tea inside, the outside is comfortable to hold, so no worries about the lack of a handle. Conclusion: This Ember Cup has everything that’s great about the larger Mugs but in a smaller size and without a handle. The same great apps, the same great features, and a fresh handle-less design let you savor your favorite smaller hot beverage for as long as you want.

This is my third Ember mug purchase. Last Christmas got 14 oz mugs for both my wife and myself. I keep mine at work at use it every day. It works exactly as promised, and I know I can leave my coffee alone for a little while and it will still be as hot as I like it when I return. If you can get that mug at a discount price, it's really worth it. Regarding this Ember cup, I make espresso based drinks, primarily Flat whites, every morning when I'm home. I tend to take a little time drinking this, and lately have become a little frustrated that the drink gets a little too cold by the time I get to the end. This little baby solves that problem completely. If you're going to use this for a cup of coffee, definitely go with a bigger size. However, if you like espresso, latte, cappuccino, etc. don't hesitate. Just get this. You can pour latte art and have your same drink experience. I especially like that you can set the temp a little lower as that is perfect for me. Espresso drinkers, you'll be glad to have this mug.

I love this cup and warmer. My coffee stays a perfect temperature. Please note the size of the cup, as it is smaller than your typical coffee mug.

Kept the temperature exactly how i wanted it to and its easy to clean

I saw this mug and spent most of a year debating getting one (price is outrageous). I nurture my drinks for hours and every time it got cold i thought "wish this were still warm". Finally bought the cup and am extremely happy. Hot drinks for hours.
