Kepwam Self-Heating Coffee Mug T2, 16oz Electric Heated Mug Hot Up to 149℉ | No App, 3 Temp Settings to Keep Coffee Warm, Long-Lasting Battery for Office & Home,Auto Shut-Off, Ideal Gift for Men & Women

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.!

Even though I only have one cup of coffee each morning, I want it piping hot. I did not want to have to microwave it to keep it at my preferred temperature.I found my solution by purchasing the 20 ounce version of this mug. I can take my time in the morning and really enjoy my coffee now.I appreciate the large size and find it to be a comfortable fit in my hand. The outside stays cool while the magic happens on the inside.I found the battery life to be great. Upon opening the box, I noted it was already partially charged. It doesn’t take long to fully charge and I have found I can go 3 to 4 mornings prior to recharging it. The included lid probably helps it maintain the preferred temperature.Upon filling the cup, it only takes one press of the side button to turn it on to the highest setting. I have used a competitor’s brand that pairs with Bluetooth on an app, but did not like occasionally having to go through the process again to “recognize” my cup. They also did not offer such a large size mug.I’m very pleased with this purchase!

I like this cup because it does keep my coffee and tea hot...albeit at the highest setting. My definition of hot is the same as how the coffee comes out of the carafe, freshly made as well as the hot water for my tea. That temp is the same as the highest setting. It also helps to keep it hot with the lid that comes with it.Speaking of the lid, my concern is how it "burns". If you put a hairdryer on high and put it close to plastic, it will warp it and if it doesn't, it will definitely burn it. You will see the surface scar with burn bumps, if you will. That means the plastic is not high temp safe = plastic in your hot cup of coffee or tea. This explains the taste I had on my first night with hot tea. It tasted funny and I played it off as it's first burn. This morning I clean the lid after my coffee and notice the part of the lid is still clear, but the other side and middle has scuff marks because it's no longer clear, but cloudy. I can feel a texture that the clear side does not have and that is clearly plastic burning from the heat.I included two pictures to show the new "frosted" look of the lid. The darker one has a clear area that you may see the texture of the tray that it is on. I took a third picture where you can see through the lid in that same area to the mousepad underneath, while the other areas are burned or scarred. Please note that this lid used to be clear and see through. I will not be using this lid and may send this entire thing back because that is not good at all. That is low quality plastic that I most likely ingested while drinking my hot beverage.The bottom of the cup also shows some anomaly that shouldn't be there, almost as if it was also burned. In the picture, the bottom of the cup has a new texture that wasn't there before. I checked this cup to see if there were anything odd about it as a new cup and there was nothing to note. The bottom of the cup was as smooth as the sides of the bottom are. Note that the center of the bottom is thinner than the other area. You can push down and feel it give. Tap the middle, then tap the sides of the bottom and you can hear a hollow sound in the middle and you can hear it become more solid and sturdy closer towards the sides. The paint and how it is applied may not be as quality as it looks. I'm returning this. I have other metal mugs with clear plastic lids that have not done this in the years that I have had them. Enter this item and the lid burns along with the paint on the bottom of the cup where the heating element is.

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!

purchased this heated mug specifically for desk use, and in that context, it mostly does what it’s intended to do. What initially attracted me was the large capacity, since I prefer a bigger mug that doesn’t need constant refills while I’m working.The mug feels solid and well-made. I like that the main body is not plastic, which gives it a more substantial, durable feel on the desk. The bottom has enough grip that it stays put and doesn’t slide around easily, and the overall design looks clean and modern. There are also several color options available, though I chose black and later realized I might have preferred a lighter color, like I am now drooling over the lilac colored one and wish I would have gotten it.The operation is very simple and doesn’t require an app, which some people will see as a plus for a work setup. Everything is controlled by a single button on the side of the mug:Press to cycle through three heat levels (low, medium, high)Indicator lights show the active settingThe mug shuts itself off if it’s empty or inactiveIt charges on the included base and takes several hours to reach a full chargeFor desk use, this simplicity is convenient—no phone pairing or software needed. That said, I do miss the finer temperature control that app-based mugs offer.My main downside has been battery life. On my unit, the mug sometimes powers off before I’ve finished my drink, which is noticeable during long work sessions. Because this is a larger mug, I expected it to stay active longer between charges.The mug is also fairly heavy when full, so I wouldn’t consider it a travel mug. It feels best suited to staying on a desk rather than being carried around, and the plastic lid is more about heat retention than spill prevention. I also wish the lid was metal, not plastic.Overall, this is a good desk companion if you want a large heated mug with straightforward controls and don’t mind recharging it regularly. It’s not perfect, and at this price point, I expected stronger battery performance, but for keeping a big cup of coffee, tea, or broth warm while working, it generally gets the job done.

I'm very pleased with this heating mug. I got it to replace an Ember mug I had been using for many years. Pros: much cheaper than the Ember. Doesn't seem like the coating will delaminate like the Ember, but I will update if it does. (That was my biggest beef with the Ember, who knows how much of that coating I ingested over the years.) Super cute lavender color. Larger than the Ember but with a slightly smaller charging plate (more capacity and smaller footprint!). Doesn't need an app! Haven't found any cons yet, except as others have mentioned, the handle is a bit thin and not the most comfortable. Def NOT a deal breaker to me. The medium temperature setting is plenty hot for me, it's hot but totally drinkable. I've only had it a few days, but it seems to heat fast, maintain temperature well, and overall I am just really happy with it!

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.

The cup is everything I needed it to be. Keeps coffee hot for 2-3hours. Is truly excellent!. I do have a small issue with the lid. It does not seem to have an air port to allow smooth delivery of the hot liquid through the opening. Most of the time I have to cautiously draw in a breath while drinking to allow a slow flow. It somewhat restricts the liquid and then quickly allows it to flow into your mouth. It is somewhat like drinking ice water and at the end you tip it up and the ice releases from the bottom. Somewhat surprising in effect. I highly recommend this cup.

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 .
