Customer Review: “I love how the mug senses when I pour hot liquid and goes to sleep when not in use. The battery lasts well enough for my workday, especially with the charging coaster.” – Sarah T.

Customer Review: “An Improved Ember Cup, and Without Handles To Mindlessly Bump Into. Just What I Was Waiting For. Thank You!” – Dave L.

Customer Review: “Pricey, but worth it. No more throwing away cold coffee.” – Allison R.

Customer Review: “I’ve been using the Ember Smart Mug 2 almost every day for about a year (I skip caffeine on Saturdays), and it’s easily one of my favorite purchases. I haven’t had a single issue with it during that time.What I like:Keeps my coffee at an exact, consistent temperature once setThe app lets you dial in your preferred temperature, and the mug remembers it afterwardBuild quality feels premium, and the copper finish looks great on my deskWorks especially well when paired with a sliding lid to extend battery lifeWith the lid, I rarely need to use the charging coaster while drinkingWhat could be better:The app can be a bit annoying to use, especially during initial setupBattery life is short without a lid, so slow sippers will want the charging plate within reachOnce everything is set up, the app becomes mostly hands-off, and the mug just does its job. If you like your coffee or tea at a precise temperature and tend to sip slowly, this mug—especially with a lid—has been a daily essential for me.” – Jamie S.

Customer Review: “This is my third Ember mug. The first two were gifted to me. I am a coffee sipper not a gulper. I was constantly reheating my drink prior to receiving this gift. These mugs typically keep your drink warm for about 80 minutes before needing recharging. So this indulgence is perfect for me. My only complaint is that it only lasts about 2 years before the battery no longer holds the charge that long. I give it 5 stars for the first year then things start to go down hill after that. Maybe I am being unreasonable expecting something in this price range to last more than two years ?” – Linda K.

Customer Review: “Keeps my coffee hot for hours and the spill-proof lid is perfect for my commute. The LED lights are helpful to know battery status.” – Melissa P.

Customer Review: “Simple to use and reliable heating. I like that I don’t need an app to control it, just a button press.” – Jason R.

Customer Review: “I love using the Ember Tumbler on hiking trips. The battery lasts long and it keeps my drink perfectly warm. The water resistance is a big plus.” – Emily W.

Customer Review: “A great travel mug with smart temperature control. The two lids are handy depending on the situation.” – Robert M.

Customer Review: “I wanted to give this mug a fair shot before writing a review—several uses in, and I can confidently say it’s a winner. This temperature control mug does exactly what it claims to do: it keeps coffee hot (not just warm) from the first sip to nearly the last.The mug is easy to use, with one intuitive button and a clear indicator light showing three heat settings: warm, hot, and “piping.” I prefer my coffee piping, and the high setting keeps it at just the right temperature for me. Battery life has been solid—up to 2.5 hours as advertised—and the five blue indicator lights make it easy to track remaining charge. Of course, using the higher heat setting drains the battery a bit faster, but that’s expected.One standout feature is the included charging base. When I’m at my desk, I keep the mug on the base while sipping, which helps preserve battery life. The base has two raised contact points that align with the inset conductor rings on the mug’s bottom, so there’s nothing to plug in—just set it down and go. Simple and effective.There’s also an auto-off feature that detects when the mug is empty. While I haven’t tested it deliberately, I’ve noticed the last sip is sometimes cooler, which makes me think the mug powers down before it’s completely empty—a smart safety feature, especially if you’re forgetful or distracted (no one wants melted plastic or worse!).The mug holds a standard 8-ounce pour comfortably, even with room for cream—though I drink mine black and untainted. It also does a great job maintaining heat even without the lid, though I imagine it retains heat even better with it on.Bottom line: this mug offers excellent usability and functionality at a significantly lower price point than some of the better-known competitors. If anything changes down the road, I’ll update my review—but as of now, this is a fantastic value and a great buy.” – Alex M.

Customer Review: “The KEPWAM 16oz Smart Heated Coffee Mug does a great job of keeping a hot cup of coffee at your desired heat level for several hours. With three temperature settings to choose from (warm – 113°F, hot – 131°F, and piping – 149°F), one is bound to be “just right” for you (not too hot, not too cool)!The cup itself is very attractive and there are several color options available. Again, you should be able to find a color that is “just right” for your taste.I have found the battery life ample to get me through my morning routine, with the cup maintaining the mid-level temperature for about 4 hours on a full charge.There is also an option to keep the cup on the charger plate while in use, which will keep the charge all day long. Of course, that defeats the “portability” benefit of a self-powered heated cup. I have been using a warming plate for years, but have had to sacrifice the ability to take my coffee with me to another room and keep it hot. So, whether you use the portability feature or fixed charger plate option, one is bound to be “just right” for you!They do list the “capacity” as 16 oz. While this is, technically, a true statement, 16oz fills the cup to the very tip-top of lip (see photo). Of course, a cup this full cannot be moved without spillage, so the “usable” capacity is more in the 14 oz. range. Also, they similarly list the capacity as 14 oz with the lid attached. Again, this is an overflow level. The “usable” capacity with the lid is more like 13 oz. (see photo).Other key things to note: the cup cannot be put into a microwave oven, nor can it go into the dishwasher (hand wash only, I wouldn’t recommend submerging, although a quick dip in soapy water and a gentle rinse should be OK).Even though it comes with a lid for travel, note that this cup most likely will not fit into a car’s standard cup holder. The handle is such that the cup cannot nestle down inside the cup holder. But for moving from room to room, the lid can be a handy plus for this cup.Overall, this is a great cup that does keep a beverage at a good drinking temperature for several hours.5 STARS AND I DO RECOMMEND THIS ITEMI write honest reviews based on real life experience with each item to help others make informed purchases. I read reviews too, and appreciate how helpful they can be. I hope that you find this review helpful!” – Dana H.

Customer Review: “I have 4 of the Ember mugs. I have the red travel mug, the 12 ounce copper mug, the 14 ounce mug in a stone color and this 6 ounce mug. I get more use out of this mug than any of them and this wasn’t my first ember purchase. I love this mug. When I have to get ready for a meeting on the fly, I’m grabbing this mug because I want to get through my coffee a little quicker. It’s the right size for quick coffee that you won’t have too much time for sipping on hours. It’s the perfect size when you don’t want a lot.More importantly its size doesn’t lessen the amount of time your coffee stays hot either. I’d say to me it appears to stay hotter longer than any of my mugs and that could be due to its size. I love these ember mugs so much. My daughter started me on the journey and I’ve been on it ever since.” – Grace T.

Customer Review: “I’ve always had to drink cooled espresso drinks because the small volume (2 oz)) cools quickly. And anyone who has to feed complaining cats knows there isn’t time to drink hot espresso. The Ember, set at my preferred temperature, keeps the coffee hot for delayed drinking. Expense is high but I don’t know how I managed this long without splurging on such a great cup.” – Peter H.
