Super happy with the Nextmug Plus
I’d wanted a self-heating mug for a long time, but the “name” manufacturer didn’t offer a larger size until very recently. I purchased the NextMug Plus in 18 oz and have been really happy with it. The battery lasts a long time (though I have the charging base at my desk, so longevity is never a problem), and it’s well sized to give me a large cup of tea or coffee to nurse for a while while staying piping hot. I set mine to the middle level of heat (out of three options), and I find that as hot as I want it. The third level is almost scalding to me. While it is hand-wash only, it is easy to clean, having a wide mouth and good handle to hold on to while soapy. I use a fat bottle brush in it, and it works fine. It also has a temperature gauge on the side to show you not only the setting you’ve set, but also the relative temperature of the contents. It won’t fit into a car cup holder, so travelability is limited, but the lid is splash resistant (not splash proof). I like the slate blue color I purchased; it’s a good looking unit all the way around, and it feels solidly built. Overall, I’m very impressed.

5 star on all counts as long as coating holds up
So far I give this a 5-star review, however, time will determine whether the coating holds up better than Ember. I like the larger 18 oz size of this mug, and the feel of the coating. I defected from Ember mugs as their coatings do not hold up over time. Considering the cost of these mugs, I want it to last more than a year and not worry about the coating material seeping into my coffee or tea–not to mention it just looks gross.What I like better than Ember:1) Nextmug is a manual operation with simple on-off and temp buttons on the base of the mug. It can be set to one of three temperatures (At first I was setting it to the highest temp, but found that the second one is better for me for an easily drinkable temperature.)2) I also like being able to turn it off when I finish the cup to prevent the congealing of remnants on the bottom of the cup like happens often with the Ember mug (yuck), and that it doesn’t drain bandwidth from my wireless network.3) Also I found that Ember mugs would not heat the liquid back up if it had cooled down (this happens if you have the mug off the charging coaster for too long or leave it sitting for too long). The Nextmug also has an auto shut-off, but it will heat the drink back up if you reset the temperature.4) I like that they include the lid with your purchase. This helps keep the drink hot longer, which preserves battery life.Tips:1) I don’t use a metal spoon and keep a plastic spoon (you know, one of those heavier duty ones you get from the froyo stores?) by the coffee pot to stir sweetener or creamer with these mugs, just to prevent unnecessary scratching (as I did with Ember), and only hand wash as per instructions from the manufacturer.2) I have also purchased two additional charging coasters so I can have one by my living room chair and by my desk where I spend the most time, and one in the kitchen for overnight charging.All I can say is if the coating material doesn’t degrade like the Ember mugs have (I’ve seen this happen on the three different Ember mugs we’ve owned as well as several my daughter and husband have purchased), it will hands down be my preference and recommended self-heating mug option. I will update my review if I see the coating begin to degrade, but I purchased this in Nov. 2024 and so far so good.

Make Nextmug your next Mug….
This cup is incredibly versatile and has three heat settings: 130°, 140°, and 150°. These settings work well for me, allowing me to brew tea, coffee, and hot chocolate to my preferred temperature. The charging coaster pens are significantly larger compared to competitors, providing ample power for charging. Additionally, the cup displays the current temperature and battery level at a glance, making it easy to monitor its status. The 18-ounce capacity is perfect for my needs.About nine months ago, I bought a competitor’s cup (the largest available 14oz). Unfortunately, I didn’t use it for more than nine months. It began overheating, causing the charging pens to burn. After burning up three coasters, I realized that the problem wasn’t the charging stand; it was the cup itself.

Quality, best stuff available. Size matters!!!
I have it several days now. Piping hot is awesome. The feel and the build is magnificently done. I bought the 18 oz. I love a big cup. I saw the Ember at costco, it is so small not worth the purchase. When I purched this NextMug I bought the 4 year warranty for only $32.00. Its a fantastic Insurance Policy to have. If you can afford the NextMug I highly recommend this product.

Great Mug! Expensive, But It Works
I got this Nextmug Plus for my wife and I haven’t seen her drinking her morning coffee in anything else just yet. It works as stated. Keeps hot drinks hot and warms up as well. Just be aware that warming up drinks really drains the battery. Cleaning is easy. Really happy with the purchase! The battery could last longer, but it does indeed last for the durations stated, for atleast the following week after starting to use it. Expensive, but worth it to those in the world who like to enjoy their drinks slooooooowlyyyyy throughout the day
Customer Review –
Hot coffee for hours
I purchased this for my husband for Christmas and it has become his new favorite. This is a solid build and performs like champ. It came with easy to understand instructions. The cup sits on a base and keeps the coffee warm for hours plus the cup heats itself allowing you to take the mug with you while it retains it heat. It is a sleek beautiful design, with a lid to help contain the spills or splashes.

Great, While It Lasts!!!
This mug does what it’s supposed to do very well, but it’s unreliable. The first one I received didn’t work, but customer service was good and they exchanged it. But that as of yesterday just stopped working. I trade very good care of things. It lasted less than a year. Not a good bargain at the price!

TOP NOTCH CUSTOMER SERVICE
I don’t write reviews very often, but Nextmug truly impressed me. The mug itself is fantastic. It looks great, keeps my coffee warm exactly as advertised, and has become part of my daily routine. What really stood out, though, was the customer service. Friendly, quick to respond, and genuinely helpful. When you’re buying a premium mug, that kind of support matters. This is my third Nextmug and I’ll gladly keep recommending them to friends and family. ⭐⭐⭐⭐⭐

Used daily to keep coffee in good temp
Simmo Hall –
Does what it says on the box!Piping mode kept my coffee at the perfect temperature, right to the last sip. That is, really hot – right on the cusp of being too hot. And I drank it over an ~20min period. After which, the battery meter still showed 3 out of 3 LED’s.The 18oz version allows ample space for the standard 2 shot, 12oz or medium flat white from your barista (~20mm below the rim).The mug is beautifully aesthetic, and feels great in your hand. It’s a little heavy, but what do you expect from an electronic battery powered device with enough oomph to keep your coffee piping hot for a more than ample time period.It’s an indulgent purchase. It’s a ridiculous expense. But it appears to be a high quality product – I’m keen to see how it performs with daily use – hopefully it continues to perform for years? It definitely appears as though it will.If you like your coffee to stay nice and hot, this is what you want!Warning: You’ll need a US to Aus GPO adaptor, but they are cheap and readily available.

Schöne Form und Farbe. Mit 510 ml tolles Volumen, Gewicht okay. Einfache und intuitive Bedienung (für das Ausschalten muss man allerdings immer durch das ganze Menü, LED-Anzeigen etwas tief und schlecht einsehbar positioniert). Ladevorgang dauert recht lang, der Akku ist recht schnell leer. Lange Lieferzeit. Wird leider nur mit US-Netzstecker geliefert, sodass ein Adapter erforderlich ist.

It really keeps the coffee hot even on the lowest setting, very nice! Much easier to use then others I’ve tried, very user friendly. The thin rim makes drinking very pleasant. The one downside, the battery life is very low, especially for the price paid for it , it should have a much bigger battery. But all in all, it works great, confortable and user friendly, thumbs up 👍
