Nextmug Comparison Chart Nextmug Nextmug Plus Nextmug Go Nextmug Ultra Review: Best heated mug I've found. - Great products, Great company awesome customer service. Keeps my coffee hot. No need for an app. Simple, straight forward to use. The lid fits snugly and they offer travel lids. (All lids and bases are interchangeable) I've had it for 18 months and It stopped charging and i contacted company. They got back right away and helped me troubleshoot. Turned out one of the charging pins broke off. They sent me a new base. These days it's rare to to find a company that stands by their product especially after 18 month. Love this Colorado company.

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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Best heated mug I've found. *by C***E on April 22, 2026* Great products, Great company awesome customer service.

It does exactly as advertised. It keeps my coffee at the exact temperature I want. The battery charge last quite a while,,, lots of time to finish my "hot" coffee. Looks great too. Highly recommend. ### ⭐⭐⭐⭐⭐ Fantastic, better than an Ember cup! *by L***Y on September 20, 2023* I have an Ember and Nextmug. I’ve had the Ember over two years and the base broke. One of the tiny little spring-loaded nibs lost its springiness. A weakness in design if you ask me. But, the Nextmug uses the same little nibs. Their design is a little stronger in that one nib is right in the center of the cup-base. But still, a weakness in design that you cannot (and I stress CANNOT) get the baseplate wet. I’m not sure what happened to my ember, but I ended up making a solid nib out of solder for the one that lost its spring. It’s holding, but I’m not confident in it. I’m guessing at some point, the Nextmug base will do the same thing. That aside, the Nextmug is superior for a few reasons. One, it has a definitive on and off option. Where the Ember has a sensor to know when you’ve added liquid, it’s hit or miss. The Ember on/off switch is also inconveniently located underneath the cup. And it also is hit or miss. Where it gives you a tactile response that you’ve clicked it, it’s unclear most of the time what you’ve actually done. Sometimes a light comes on, sometimes not. Sometimes it’s blinking red, sometimes it’s solid red, green, white, blinking… The Nextmug on/off is located on the side (superior) and it’s easy to know when the cup is off (no lights) and which option you are picking. The Ember app? Garbage. It is unreliable. If it works, it’s fantastic. The trouble is that it rarely connects no matter what you do. When I went shopping for a replacement, I specifically looked for cups that did not have an app. “App” means IT developers, means more cost, and generally for a product like this, average developers (I mean, it’s a cup not an air-traffic control system). Plus, the Bluetooth chips they must use have to be the bottom of the barrel (aka, unreliable). Therefore, all the features that the app provided (heating options most notably), were useless to me. The Ember cup size (10 oz) was a little small. There’s now a 14 oz option, but the train had left the station! The Ember on/off button on the bottom of the cup, again, is a nuisance. And here’s something I didn’t think I would care for… the Nextmug lid! I have to say, it’s great! It helps keep the coffee warmer without using as much energy (longer charge when it’s away from the base). Also, it nearly erases evaporation. And, I’m not 100% sure, but the coffee seems to be much less bitter because of it. Maybe my imagination, but the coffee taste better from the Nextmug cup. Plus, no spills (or at least, less chance of splashing). The Nextmug light indicators where intuitive and having a button for “warm, hot, and piping” versus an app… Way to go Nextmug! Between the Nextmug and Ember, it was an easy decision for me. I’m still concerned about the little nibs losing their springiness… But, there you have it. ## Frequently Bought Together - Nextmug - Temperature-Controlled, Self-Heating Coffee Mug (14 oz.)
