Kepwam Lilac Violet 16oz Smart Heated Coffee Mug, 150 Min Battery Life - Hot up to 149°F, Stainless Steel & Ceramic, Purple

Great product, I already bought 3 mugs and I'm happy with them so far.

It is very nice and does the job well.

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 ITEM I 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!

Don’t buy it. It was washed by hand by my self and After only two months does not work anymore. Support is unreachable, impossible to talk to someone to tell my problem, talk to the seller is impossible. Please don’t waste your money with this mug .

I previously owned another brand cup, which was a gift and was the first time I’d heard of self warming coffee cups. I was immediately enamored because I am a slow coffee drinker normally only have one or 2 cups a day and they would stay warm as long as I needed them to… However, before too long I had problems with the charging base and the contact points and they eventually failed customer service was not good. Had to buy a new cup and when that one also failed I decided to try the Kepwam. So far, I am extremely happy with the quality and usability. The touch buttons with which you set the temperature you like are easy to use and if you keep it on the charging base, it’ll stay warm as long as you leave it on there-when it’s off the charging base the top works very well at helping the battery last longer and I’ve never really not finished a cup that wasn’t the temperature that I preferred up to at least two hours. The charging base and contacts are much more robust than my previous cup. Price point was also much more attractive than previous brand. I did have trouble with the first cup that I owned, but found out that it was probably due to my not paying close attention to the use and care directions and may have caused the failure, however the company immediately replaced it with a brand new one so I’m very happy with customer service also. Really like some of the new colors.!

Updated review in 2026: Just shy of a year of purchase, I started having trouble with my cup. The lights would just flash and turn off instead of staying on and keeping warm. It didn’t work if my cup was full, and the battery was fully charged. I contacted the company here through Amazon (I couldn’t find any other way on any other site or email). After some troubleshooting back and forth, they sent me a whole new mug that is working perfectly. I’m not sure what will happen if this one also fails. But I’m glad to have a replacement at no extra cost. That’s good customer service! Also an update on my replacement lid from the 2025 review—that lid also broke eventually. I have a new lid on the new mug and we’ll see how long it lasts. It appears to be the same one. Original review in 2025: I love love love my mug! I’ve owned it for about 7 months now and I use it daily all day long. I put it on the charger at night and it lasts me on low for the whole next day until about 5-6pm. The low setting is perfect for my coffee, personally. I do mew the lid on full time and I think that helps with temp control and battery longevity. My mom has the same mug and she keeps the lid off. Her battery lasts less time and she has to keep it on the medium setting. So if you’re having less performance than you’d like, try keeping the lid on. I like the purple color the most, though I would have preferred green or blue. However, I don’t like the “dusty” shade look of the colors. The touch buttons are perfect I think because they are actual buttons you have to push yet there aren’t any cracks for liquid to get inside. I don’t have to worry about accidentally hitting a touch screen button either. I only have two small complaints: 1) The lid broke the first time I tried to remove the black slider to clean it. Now it’s too loose and the slides closed on me when I try to drink. I ordered a replacement lid and it’s been ok so far, a few cleanings in, but it’s loosening as well and sometimes slides closed on me. I’m not keen on buying another lid that is both difficult to clean AND prone to breaking. 2) The wide shape of the cup means it doesn’t fit in any of the car cup holders. I’ve taken it in the car on many occasions and I have to set it inside my console, where it has spilled a time or two. It does fit inside my mom’s Honda pilot cup holders, however. Overall, I still absolutely love this cup and it has been a game changer for actually finishing a cup of coffee before it gets cold! Perfect for a busy homeschooling mom of 3. Best Mother’s Day gift ever!
