Hot Coffee Should Stay Hot
There’s nothing worse than sitting down with a fresh cup of coffee, getting lost in work, and then taking a sip only to find it’s gone lukewarm—or worse, ice-cold. It’s a universal struggle for coffee and tea drinkers alike. Sure, you could microwave it, but we all know that never quite brings it back to life the way you want. That’s where the Ember Mug 2 comes in. This isn’t just another trendy gadget; it’s a real solution to a problem every hot beverage lover faces. And after using it, I honestly don’t know how I ever settled for cold coffee before.
Sleek, Modern, and Built to Impress
Right out of the box, the Ember Mug 2 feels like a premium product. The smooth ceramic coating gives it a refined look, and it has just the right amount of weight to feel solid without being heavy. It comes in 10-ounce and 14-ounce sizes, and both have the same minimalist design that fits effortlessly on a desk, nightstand, or kitchen counter. The charging coaster is compact and sleek, blending in rather than sticking out like an unnecessary extra piece of tech.
The LED indicator on the front is a nice touch, changing colors based on the mug’s status—heating, ready, or charging. And if you’re the kind of person who loves customization, you can even change the LED color through the Ember app. Completely unnecessary? Yes. Fun and weirdly satisfying? Also yes.
One thing to note: while it’s durable, the mug isn’t dishwasher safe. The stainless steel interior with its ceramic coating needs to be hand-washed. Not a huge deal, but if you’re someone who throws everything in the dishwasher without a second thought, it’s worth keeping in mind.
Temperature Control That Actually Works
This is where the Ember Mug 2 really shines. It keeps your drink at your preferred temperatur for up to 80 minutes on battery, or indefinitely when placed on the charging coaster. You can set the temperature anywhere between 120°F and 145°F, ensuring every sip is exactly how you like it.
I tested it with my usual morning coffee routine. I poured in my drink, set it to 135°F via the Ember app (which, by the way, is incredibly easy to use), and then got completely sidetracked by emails and a phone call. Normally, this would mean coming back to an undrinkable, lukewarm disappointment. But an hour later? Still hot. Still perfect. It’s almost like the mug was patiently waiting for me to return, like a loyal little caffeine-keeping sidekick.
The best part? No more chugging coffee in a rush before it gets cold. No more microwave re-heats that somehow make it taste slightly burnt. Every sip, from the first to the last, is exactly how you want it.
The App: Surprisingly Useful
I’ll be honest—I rolled my eyes at the idea of needing an app for a coffee mug. But after using it, I have to admit, it’s actually pretty convenient. The Ember app connects via Bluetooth and lets you set your preferred temperature, customize the LED color, and even name your mug (mine is now officially called “Mug Life”).
That said, if you’re not into the idea of app-controlled temperature, don’t worry. The mug remembers your last setting, so once you set it up, you don’t need to open the app unless you want to change something.
Battery Life and Charging
Battery life is solid, giving you about 80 minutes of use on a full charge. If you’re someone who nurses one cup of coffee for half a day, you’ll want to keep it on the charging coaster to extend the warmth indefinitely.
Charging is simple—just place the mug on the coaster, and that’s it. No need to fumble with plugs or remember to charge it separately. It takes about two hours for a full charge, but since most people will leave it on the coaster between uses, I never found myself waiting on battery life. Also, the mug automatically shuts off when empty to save power, which is a small but thoughtful touch.

Final Thoughts
The Ember Mug 2 is one of those things you don’t need but will absolutely love once you have it. If you’re the kind of person who gets distracted and ends up drinking cold coffee more often than you’d like to admit, this mug will change your morning routine. It’s not just a gadget—it’s a simple luxury that makes every sip better.
Would a regular mug still hold coffee? Of course. But once you experience drinking at the perfect temperature every single time, it’s hard to go back. If you love your coffee hot and hate playing the microwave game, this is absolutely worth it.
And if you ever hear a goose honking outside, don’t worry—it’s just jealous that your coffee is still hot while its pond is freezing over.
