Review: Better than expected! - 2nd UPDATE: It is now April 2026. A sad day. It seems that the mug no longer heats up, even when sitting on the charger. Time to be replaced. Total lifespan was just about 2.5 years for anyone looking to purchase. UPDATE: It is now May 2025. About a month ago, I noticed that the mug no longer held a charge after about 5 min. I sit near my coaster all day anyway (desk job) so I just kept it on the coaster and it was fine. Unlike the Ember mug I had, this still kept things hot while on the charger. But now I'm also noticing it seems to auto shut-off after about an hour or two, so I have to keep an eye on it to make sure it doesn't turn off. I'm a sipper so, yes, I do take hours to drink a mug of whatever! *************** I purchased this mug in Nov of 2023 and wanted to give it a good, long use before reviewing. I had previously gotten and used another, more expensive electric mug which is sold in all the stores at Christmas time. With THAT mug, you could set the temp of your mug via their app to a specific number and that was nice so I didn't expect to like this mug as much. But with the other mug, the coating inside the bottom wore off in about 6 months from stirring and after about a year, it really didn't keep my drinks piping hot anymore. With THIS mug, I use the middle (of the 3) setting, "hot" and it is piping hot for me. The hottest, "piping" is too hot (I used the max number on the previous mug to get it to the heat level I wanted). I have also not had a circular path appear on the inside bottom of this mug. And, a year later, it is still going strong. CAVEAT: I do keep it on its coaster the whole time and sip as I work (it takes me hours to drink a mug of something)... when I happen to be up and take my mug, without the lid, the charge lasts on HOT for about an hour. Maybe 90 min with the lid on. I am still quite satisfied! The previous mug's charger was concave and this one is convex, so I just had to get the hang of placing it on the charger correctly without it toppling over, but that was an easy adjustment. Both mugs are heavier than a standard mug (obviously - there is a battery in the bottom!) but I got used to their weight. I am very happy with my Nextmug and would buy it again!!
Review: Better than EMBER - I love this cup! Bought this one after my Ember died. The pink is super cute. Most importantly it does not need an app and you control the temperature. At first I had issues with it and had planned to return it but have to admit it was operator error. I decided to try it one more time before I returned it. It comes with a cheap plastic lid which I did not like. The TALL cup comes with a better quality slider open lid. I use THAT one instead. I believe you can special order the better lid. You do NOT need to keep it on the charging pad. It seems to charge fairly quickly (maybe an hour) and the charge lasts in my experience so far is 2-3 hours. I like to use highest setting. If you do not pick it up after a certain time, it will shut off. The temp control is great but keep in mind you have to keep the lid on to keep it at the temp you want. That was my error as well as letting it sit too long without picking it up. I dont like to rush my morning coffee. High temp IS HOT. If you use cream, milk, sugar it may be too hot for that. I noticed it kind of singes and sticks to the bottom inside the cup. I lower the temp when I use milk. Make sure you turn it off when you do not have coffee in it or coffee volume goes down because the last bit of coffee will be ungodly hot. Never leave it on when it is empty. And when you wash it make sure it is completely dry before you put on charger. The cup is 14 ounces which is perfect for Nepresso pods. I love this so much I never ever travel without it. Only down side is it is metal and it might be too heavy for some with hand issues.

## Questions & Answers

**Q: Since the battery cannot be changed out, only charged, how long does the battery last before mug needs to be replaced entirely?**
A: FROM THE SELLER: Thank you for your question. The Nextmug battery is rated to be fully charged 1,000 times, after which it maintains 80% effectiveness... meaning it can be charged but may not hold the charge as long as before. You'll be able to enjoy your Nextmug for years to come.

**Q: How long does the mug keep your beverage hot when not on the coaster?**
A: FROM THE SELLER - Thank you for the question.  Depending on how hot the liquid is when you pour it into the mug, the Nextmug keeps your beverage hot for about 2.5 hours (with the lid on) and about 1.5 hours (lid off) when it's not on the Docking Coaster and set to the "Warm" setting.

**Q: What's the inside coating made of? Does it have PFAS/PFOA/BPA?**
A: FROM THE SELLER: Thank you for your question. The Nextmug is made of stainless steel and has a ceramic coating on the outside. The ceramic coating covers the inside of the mug as well as the exterior surface and the handle. The main portion of the mug does not contain plastic. The bottom of the mug (only the portion around the battery) has a plastic exterior.
Both the Nextmug and the lids are BPA-free.

**Q: How many fluid ounces fit inside the cup with the lid on?  I have a competitor's 14 oz mug that holds about 10 oz.**
A: FROM THE SELLER - Thank you for the question.  When using the Spill-Resistant Lid, Nextmug holds 12 fluid ounces.

### ⭐⭐⭐⭐⭐ Glad I Didn’t Return It
*by E***. on April 5, 2026*

I read the instructions and plugged in the charging coaster, which already had two green lights and charged it until it was fully charged at three green lights which took a while. The directions were confusing to read. But it wasn’t until I actually used the mug that I was able to understand them. I was also concerned about the length of time I could leave the charging coaster plugged in for charging. I went online and ask customer service whether the charging coaster could be left charging overnight, but never heard back from them. But I figured if the charging coaster could be left on indefinitely according to the instructions when drinking coffee at any temperature, I could charge it overnight. The charging coaster didn’t get hot nor did the plug. The first time I used the mug I had it on warm uncovered, which was the perfect temperature for me. My 1st cup of coffee stayed warm for just under two hours. For what I paid, I was not happy and thought about returning the mug. I chose this type of coffee mug because I need to use it without the charging coaster. So I tried again and followed the directions, using what I learned from my first cup of coffee. Pulsing lights, heating up, pulsing lights cooling down. There are pictures and few words, but I figured it out by just using the mug. For my second cup of coffee I did use the lid. I prefer not using lids, but it made sense not to lose heat. Warm is the perfect temperature for my coffee and it stayed warm for about four hours. Yah! The next test was finding out what would happen if I added coffee to the coffee left in the mug. (I make French press coffee and it doesn’t stay hot for long,). When I added the coffee, the light started pulsing letting me know it was heating the coffee. Okay! And it did and it was perfect and didn’t take long. The final test was a cup of tea. I made the tea in the mug and set the temperature to warm. Pulsing lights again but this time to let the tea cool down!!! One of the reviews I read before purchasing the Nextmug mentioned that the coffee tasted better. For me it’s that first sip of coffee that’s the best. But with the Nextmug all the sips taste like the first sip. It took me by surprise. Same temperature and same wonderful flavor from start to finish. I love this mug and highly recommended it. But it is a little pricey.
