If you're a slow drinker like me, this is the mug for you. No more cold drinks to shamefully reheat in the microwave, stovetop, or pour out with a standard mug. It has a good battery, but I always make sure I have the charger near me so I can keep this going longer. The peach color is adorable. The lid is a nice touch, too. Also this thing keeps drinks HOT. I prefer my drinks too hot for most, and it was too hot for me at the highest level. Just make sure you use a wooden or silicone spoon when stirring and use only a soft sponge without a scouring pad so you don't scratch it up!

If you are like me, I get side tracked in the morning. Usually my coffee gets cold! This cup is great, when you put it on pippin, believe it truly gets really hot! The only downside is side is the battery/charge is limited to a certain time. I think $95.00 is a bit high for the cup. I’ve researched others and I know a person that has a different brand and only paid $39 for hers and stays charged over an hour. However, this is good quality made cup and easy to hold. Makes a #10 on your Keurig. Since I received the cut and start using it at the end of September 2025 until now November 16, 2025. I love it but the charge is less than 30 minutes 😞

If you like your beverages piping hot, this Nextmug is for you! I got an Ember about eight months ago and I was continually frustrated that it didn’t keep my coffee hot enough. Even at the top setting of 145 degrees it didn’t get the job done. The Nextmug does the job very well for me! No, there’s no app for your device. No, you can’t be precise with a specific temperature. But there are gradations of heat in the side. The instructions say the rightmost mark is Piping Hot, and that is perfect for me.

I'm not sure what aspect of my being this comes from, but I was finding myself constantly grabbing a cold mug when I finally remembered it was there. I'd make a pot of tea, make my cup, intentionally let it cool, and one way or another it was too cool / cold by the time I got to it. I can't say that I've been monitoring how long it took for the mug to cool down, but it always seemed too quick. I was already looking for a reason to get a new mug as the rounder handle resulted in holding it in a painful way and it was frankly getting heavier to my hands as well (being ceramic). So I had a few reasons to look anyway. And with that in mind, I decided to look for something that might help with those issues or at the least, not let the cup's contents drop below a certain temperature Long enough for me to get around to drinking it, while also having a more comfortable weight and handle. Initially, I thought about those coasters that heat up, but felt that that'd be too much of a burn / fire hazard and likely not able to control the temperature as well. Seeing as how I didn't know what temperature I was waiting for it to cool down too, I knew that I'd want something with a measured setting. I was also looking for something that could heat up a cold cup to the desired temperature. When I first saw this listing, I was taken back by the price, but not so much that it kept me from looking into it. Especially since I have a habit of deciding on things that one way or another tend to push the budget. I looked at the various aspects of the design and saw that it was basically self-contained, so there was a little to no chance of being hurt by the mug (unless I spilled the contents on the upper two settings). Being able to choose from a known selection of temperatures was a must on this purchase. I also liked that the handle appeared (correctly) to be large enough to fit my average sized, closed grip. While I've not weighed it, it definitely feels lighter than a comparably sized ceramic. Most of its weight is, of course, the battery at the bottom. I was a bit bummed that the charger was a barrel plug as that doesn't allow me to just grab the nearest USB-C cord from my station (where I sit). That said, if it Did have USB charging, then it would have only been to the base anyway, so that would be a moot point since it would likely never get unplugged unless moved. While I don't know how much my old mug held, it's quite apparent that this is likely a few ounces less, but it's also exactly 1/3rd of the 1L pot when brewed vs ~2.5 fills with my old mug. I'm sure I'll get used to the difference eventually. Now, when evaluating the performance of this, it became apparent that I was running into my desired functionality vs its design. It has become obvious that this is designed to start with a hot liquid and keep it at the chosen temperature until empty or the battery runs out. It does that quite well, but I can't say how long the battery actually lasts for sure because I lose track of time too easy. So when I say that it 'feels' like it's losing power (not temperature) quicker than advertised, I can't quantify that statement, but it 'feels' closer to 2-2.5 hrs vs 4 hrs (lid on). I can say that I figured out that my comfortable temperature is the lowest setting and that the middle temperature more closely resembles my freshly brewed pot. The charging time feels like forever, but definitely a couple hours from depleted. Now when trying to see how it does with 'heating from cold', that definitely seemed to drain the battery much faster while also taking a long time. I even tried setting it to that middle choice and then turning it back down, but that still drained the battery rather quickly. So if That is how you want to use it, then leave it on the charger until it's hot again (and expect to wait a bit). I did have to stop myself from walking it over to the microwave the first few times until I got myself better trained with how it's designed. Because of this, as much as I hate adding to an already pretty penny, I chose to purchase a 2nd base to sit where I eat / drink. I thought about moving the original base, but then I realized that it was better to leave that there for when I've cleaned the mug (default storage location and all that). What improvements would I like to see? 1) Make a slightly larger (16oz?) mug, but have it be taller so that the base and lids don't change. 2) Source a higher density battery if possible. 3) Increase the speed at which it warms up (if feasible). 4) Add a little more texture to the handle / housing as it is metal smooth and slides a bit easy in the hands. 5) Offer a closeable lid as that should prevent spills and likely assist in keeping it warmer longer.

I am beyond impressed by Nextmug. I ordered 2 mugs in November 2023 as Christmas gifts. This past summer (2025), one of the mugs stopped holding a charge. I contacted Nextmug customer support (via email) and they were prompt (responded the same afternoon) and very kind. They requested specific information/pictures/videos to confirm the status of the defective mug. I provided all requested details and they responded the same evening to confirm that mug was indeed defective and were happy to mail me a new one (they also provided a return shipping label for the defective mug to be returned to Nextmug). The new mug arrived within a week and works as expected. The prepaid return shipping label and the provided shipping bag to return the defective mug was so incredibly convenient and much appreciated. I am beyond surprised by the stellar customer service - Nextmug stands behind their products. Aside from the mugs working exactly as intended, their customer service is the icing on the cake, which is why I had no reservations about ordering the travel mug (which wasn't an option when I ordered the mugs in 2023). Our family has also tried the biggest self-heating mug competitor (Ember) and Nextmug truly is superior. The battery life and charging is consistent and the amount of time the contents stay hot exceeds expectations. I cannot recommend Nextmug enough.
