We’ve all been there: You pour yourself a cup of joe from the office coffee pot and head back to your desk, only to be sucked in by a project. By the time you’re through and go to take a sip, bleh! You’re met with cold, less-than-tasty coffee. Well, your days of being robbed of enjoying your java to the fullest have come to pass, thanks to one nifty smart ceramic mug called the Ember (from $69.99, Amazon). This temperature-controlled cup has the power to keep your beverages ready for drinking at the *exact* degree you prefer. 

Simply pour your hot liquid in and turn the Ember on to regulate coffee to a pre-set 130 degrees Fahrenheit. It can also be paired with the free Ember app, which allows you to set a temperature from your phone or smart watch between 120 to 145 degrees — a sweet spot for java drinkers.  (A 2006 study showed that coffee consumers’ preferred temperature was around 140 degrees.)

Ember App


Featuring a stainless steel interior with ceramic coating, this mug will automatically maintain the chosen temperature for up to an hour and a half when off its charger. If placed on the included charging base, however, it can keep drinks warm all day long!

Your temperature of choice can also be pre-set, so keeping your drink hot will be as simple as pouring your beverage in and turning the cup on. While the Ember is intended for use with already-hot liquids, it could, in theory, even be used to re-heat your cold brew, though it’s not recommended. Not only will it take a good long while (30 minutes to an hour), it will drain your battery fast. 

If the 10-ounce cup is too small for your coffee-guzzling self, you can upgrade to a 14-ounce version ($116.95). Those who spend their mornings on-the-go may also prefer the 12-ounce travel mug, which boasts a two-hour charge and can be adjusted via a rotating control base. 

Ember Mug


Plenty of customers are already loving this No. 1 best-selling find. “I can honestly say this is my new favorite mug!” wrote one teacher, who noted that she often has to wait until recess to enjoy her morning cup. “I love coffee, but I prefer it scalding hot. …  Now, with the Ember, I can leisurely enjoy my cup of morning coffee without worrying that it’s going to get cold.” 

Raved another: “I usually drink my coffee as I’m get ready for work in the morning. In the past, there was a small window of opportunity where my coffee was hot and the perfect temperature. … . I’d either find myself chugging my lovely cup of joe at the right temp or drinking it cold; neither was an enjoyable experience. Now, I brew my coffee … pour it into my Ember mug and it works its magic to the perfect 135 [degrees]. I don’t need to jump through hoops to enjoy my morning cup of coffee anymore. I get to start my day off with the perfect pick-me-up and it’s all because of my new Ember mug!” 

A word to the wise, however? Don’t attempt to microwave this mug or throw it in the dishwasher, as you’ll ruin its effectiveness. Happy drinking!
