I Use My Self-Heating Espresso Mug Every day, and These Choices Are All on Sale Proper Now

Prime Day 2025 ends tonight, and Lifehacker is sharing the perfect gross sales based mostly on product critiques, comparisons, and price-tracking instruments earlier than it is over. 

When the Ember mug was first launched in 2016, I used to be skeptical that it was well worth the excessive, three-digit price ticket. Absolutely, a espresso mug with a heating factor constructed into it could not be that a lot better than an insulated thermos, proper? However now that I’ve one, I am unable to return. When you drink a day by day cup of espresso like I do, earlier than Prime Day—and its competitors gross sales from Walmart, Greatest Purchase, and many others.—ends, you owe it to your self to grab up a self-heating espresso mug.

Because it got here out, Ember has earned itself a number of rivals in the marketplace, however to me, the unique remains to be the perfect. This espresso mug, on sale at Walmart, is available in each a ten oz. and 14 oz. measurement. Each value roughly the identical in the mean time and include a charging coaster. (It’s going to nonetheless warmth whereas not on the coaster, although, so long as it is charged.)

As somebody who likes to nurse a cup of espresso or scorching chocolate over the course of some hours, however who has gotten actually burned greater than I would wish to admit whereas utilizing a thermos, this has revolutionized how I drink espresso. It is by no means too heat or too chilly now, and it is particularly helpful for drinks that have a tendency to chill off quick, like scorching chocolate. The catch is that you might want to use the companion app to set your required temperature, however for down-to-the-degree management, that is a ache I am prepared to take care of. Plus, it pings me when my drink hits my desired temperature, which is handy.

It is admittedly not nice for journey, however whereas Ember does make a thermos that makes use of the identical tech as its mug, it is not discounted proper now. It is also price noting that, relying on how massive you want your drinks, 14 oz. may not be sufficient for you.

Ember mug options

Even with my testimony, I perceive if the Ember Mug is both too fiddly or too dear for you. In that case, attempt one in all these options.

The Nextmug might be Ember’s greatest competitors, and affords an analogous expertise however with out an app. Like Ember, it is a battery-powered mug with a charging coaster. As an alternative of an app, you may use a button on the mug to pick out between three temperature presets—heat (130 levels), scorching (140 levels), or piping (150 levels). There is no degree-level management right here, but when any of these presets sound good to you, you would possibly like this mug higher than Ember’s.

Or, you could possibly as a substitute pay a bit extra to go for the Nextmug Plus, which is the most important possibility on this listing at 18 oz. of capability. It is nice in case you like a big cup, and as a plus, each variations of the Nextmug include an additional charging coaster and a journey lid (it would not shut absolutely, but it surely’s higher than nothing). Like Ember, Nextmug does make a thermos, however it’s equally not on sale for the second.

Lastly, there’s the Kepwam mug, in case you’re on the lookout for a funds possibility. Each the Ember and the Nextmug value about the identical proper now, however this one is about half the value. On paper, it is much like the Nextmug, with three temperature presets and no app. These presets are a bit uncommon for my tastes—113 levels, 131 levels, and 149 levels, however may attraction to you if Nextmug’s do not. It is also 16 oz., making it bigger than both the Ember mug or base Nextmug, though it would not include a second charging coaster. On the plus facet, it does embody a detachable lid with a latch that closes absolutely. This isn’t a giant identify product, in case you could not inform by the odd variation of “maintain heat” it is named after, though Amazon critiques constantly give it 4 to 5 stars.
