- Kepwam Self Heating Coffee Mug T2, 16oz Smart Heated Coffee Mug, 150 Min Battery Life - Hot up to 149℉ Temperature Control Coffee Mug Warmer, Gifts for Dad Mom (No APP)

This mug outdoes the Nextmug and Ember cups. No app is needed. Keeps coffee hot (with lid) for a good hour and a half off of charge. If kept on the charger, hot til you drop, with or without lid. Haven't had the pins break as was easily done with the Ember cups. The Nextmug stopped charging within a few months. There are three settings for heat and there is a difference with each one. Different colors/sizes available. The cost of this mug is much lower than the other two and I have found the Kepwam to be of a better and consistent quality.

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!

I really wanted to love this mug—and for the first six months, I did. It outperformed every other heated mug I’ve tried, including some of the most expensive brands. The battery life was excellent, the size was perfect, and it consistently kept my drink at the right temperature. Unfortunately, after about six months of careful use, it completely stopped working. It won’t charge, won’t heat, and won’t turn on. Even more concerning, the bottom of the mug became extremely hot—hot enough to potentially burn—which made me uneasy given the lithium battery inside. So while it delivered six months of excellent performance, the lifespan doesn’t justify the price. If it lasted longer, it would be an easy recommendation—but as it stands, it’s hard to overlook the durability issues.

This is the coffee mug that I have elected to keep for now. I have tried several heated coffee mugs, and this is my attempt at comparison in descending order of price: EMBER PROS: - Best looking and best feeling mug. It's like drinking from a quality ceramic mug. - Large range of temperature settings for your perfect temperature brew. CONS: - My worst problem was the lack of durability of the finish. My white one stained badly, and the two black ones had the interior finish wear off despite great care and the use of silicone spoons bought expressly for that purpose. - Requires an app to check battery and set temperature. This was not a problem for me, but occasionally the mug would lose connectivity and need to be reset - a bit of a pain. - It comes in 10 ounce and 14 ounce sizes, a little too small imo. 15-16 ounces is my preferred size. - Most expensive of the self-heating mugs, but despite the price tag, I would probably use an Ember mug if it were more durable. HAPPINESS PROS: - Comes in 16 ounce and other sizes with several colors to choose from. - Less expensive than the Ember. - Has an app but it is not required to use the mug. There's a button that's easy to use and an LED display that shows battery life and temperature. - A wide range of temperatures can be selected. - I can't speak as to durability, because I decided not to keep it. One big CON: - It has a cheap feel. The rim is thin and "plasticky" feeling, so drinking out of it is not as pleasurable to me as drinking out of the Ember. Unfortunately, this was a dealbreaker for me. KEPWAM This is the one that I have elected to keep for now until my "perfect" mug is available. PROS: - Good price - Comes in a 16oz and other sizes with several colors to choose from. - I was initially concerned that there were only three preset temperature options. I thought that my preferred temperature would be between medium and high, but as it turns out the high temperature is fine for me. CONS (or still not sure): - As others have mentioned, the handle is too thin and not comfortable to hold. I decided this was less problematic than my issues with the other mugs, but it would have been so easy to make a comfortable handle. I found a silicone pot handle cover that makes the handle a bit better (see photographs), but it is still not ideal. - No option for an app, but this might be a desirable feature for some. It is certainly easy to operate the mug with the button. - The temperature does not always seem to hold steady, particularly if I haven't taken a sip for a couple of minutes. I'm not sure if that would be the case if I kept it on the charging plate. - I'm not sure how well it will hold up, but for the price I'm willing to take a chance.

I purchased 2 Kepwam 20 oz. heated coffee mugs over a month ago. My husband was grumpy about the price of his surprise, but now he’s smiling and recommending them to everyone …👍! We’re coffee drinkers. We LOVE these mugs ! They keep our fine coffee at the perfect temp. for 8 hours on a full charge, caps on. Most importantly it doesn’t boil the coffee down and cause bitterness, it maintains it’s perfect flavor and temperature. We use them with caps always on, and I use a glass straw with mine. I was concerned about the comfort of its handle, I’m a small handed woman - but it’s nearly 3/4” width, it’s careful shape and placement make this large cup easy to balance and use - and comfortable for me. I like it’s smooth steel foundation with a porcelain-type painted finish. It hasn’t chipped or scratched and it distributes heat evenly. It’s easy to clean and good looking. We have the burgundy and black cups. I like it’s lighted and smooth control button on the cup, it’s discretely placed and easy to see what’s going on! The middle temp heating is perfect for us. I’ve used this cup almost constantly. I keep my cup at my side and mostly on its charger plate during the early day, and then it’s ready to run around with me, off charge, for 8 hours later. If you don’t touch it for 2 hrs., it safely turns itself off. It charges more quickly than I expected, and you can use it during charging. Thank you to the person at Kepwam who designed this cup carefully, with quality. These days people are searching for quality products they don’t have to constantly replace. ( I plan to buy 5 more of these as gifts, when they’re on sale!). Pamper yourself … try one of these great cups. Highly recommended!

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!

Battery life isn't as promised, but when has any company ever not exaggerated battery life? Given realistic expectations on battery life, there's really nothing not to like here. Operation is simple. The cup itself is well insulated & never feels hot on the outside. Despite the battery, it's not too heavy. I've never needed to use the highest setting. No doubt that would drain the battery quickly, but if the beverage is hot when it goes in, the lowest setting keeps it comfortably warm. I occasionally bump it up to the middle setting when I'm sitting outdoors on a cool morning and want it a bit warmer. If I have any complaint at all, it is quite slow to charge. Not a problem if you use it with the charging coaster to keep it topped up, but I often use the mug outdoors. Even so, I get a couple of 2 hour meetings out of it & put it back on the charger overnight. it's a little annoying to wash, because It can't be submerged in water, but definitely not a deal-breaker, given how well it works overall. I bought a second one as a gift a few days after buying mine and the recipient loves it as well. Added after using it for some time: Use confirmed my initial impression. If I broke it tomorrow I would not hesitate to replace it with the same brand.

The warming mug worked great for about 3 months and then just stopped charging. It was acting fickle a few days before it just quit on me and I have tried all trouble shooting tips to get it to work, but no luck. I contacted amazon customer service and they did as much as they could for me. I have also tried to contact the seller but that seems near impossible with this company., as I can not find anywhere to send them a note. Of course the return window has closed and now I am stuck with a basic plastic coffee mug. I would not recommend this product at all, but if you do buy one you need to buy the extended warranty! When it was working the battery didn't last as long as advertised and it burns the milk at the bottom of the cup, leaving the latte tasking burnt. Overall not a good product in my opinion. **UPDATE**. After having no luck contacting KEPWRM through Amazon or directly they actually reached out to me. They asked what the issue was and had me send in a couple of photos of the unit. Once they saw that I had a defective mug they sent me a replacement free of charge! I was so pleased and now that I have been using the new one, i believe that i just got a lemon, because this new one heats my coffee way better than the first one and I am super happy with it. My coffee machine spits out warm coffee at best and this mug makes it hot in minutes. I would also imagine that this one will last more than 3 months.

Ganz einfach gut

It is very nice and does the job well.

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

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 .
