The Ember Mug 2 is one of those products that sounds unnecessary until you try it — and then you can never go back to a regular mug. Keeping your coffee at exactly 135°F for every single sip is a small luxury that genuinely improves your morning. At $129.95 it's definitely premium for a mug, but if you're a slow coffee drinker like me, it's honestly life-changing. The app control, beautiful design, and satisfying charging coaster make it feel like the Apple of mugs.
The Problem It Solves
Be honest — how many times a day do you microwave your coffee? For me it was like three times minimum. I'm a slow sipper. I get distracted, I'm answering emails, filming content, and by the time I go back to my coffee it's lukewarm at best. Gross.
The Ember Mug 2 solved this completely. You set your ideal drinking temperature in the app (mine is 135°F), and the mug maintains that exact temperature from the first sip to the last. No reheating. No rushing to finish before it gets cold. It's genuinely one of those "why didn't this exist sooner" products.
How It Works
The Ember Mug 2 has a built-in heating element and battery, all sealed inside what looks and feels like a premium ceramic mug. Pour in your hot coffee, and the mug uses its internal heating to maintain whatever temperature you've set via the Ember app (Bluetooth).
The temperature range is 120°F to 145°F — which covers the ideal drinking temperature for coffee, tea, hot chocolate, you name it. It can't heat cold liquid from scratch (you still brew your coffee normally), but it maintains the temperature beautifully.
On battery, it lasts about 80 minutes. On the included charging coaster, it stays warm indefinitely. I keep mine on the coaster at my desk, so it's basically always at the perfect temp whenever I want a sip.
The App Experience
The Ember app is clean and simple. You can:
- Set your exact preferred temperature (down to the degree)
- Save presets for different drinks (I have one for coffee and one for tea)
- See the current temperature of your drink in real-time
- Get a notification when your drink hits your target temp
- Track your caffeine intake and drinking habits
The notification feature is actually super useful — you pour your fresh coffee, and the app pings you when it's cooled to your perfect drinking temperature. No more burning your tongue!
Design & Build Quality
The Ember Mug 2 looks gorgeous. It comes in multiple colors (I have the white one), and the matte ceramic finish feels premium. It's slightly heavier than a normal mug because of the battery and electronics inside, but not uncomfortably so.
The charging coaster is also really well designed — it's a flat disk with a subtle LED ring that shows charging status. It looks great on a desk. The whole package just feels... Apple-level premium. Like someone who cares about design made this.
Sizes & Pricing
- Ember Mug 2 (10 oz): $129.95 — up to 80 min battery
- Ember Mug 2 (14 oz): $149.95 — up to 60 min battery
- Ember Travel Mug 2: $199.95 — 12 oz with lid, 3-hour battery
I'd recommend the 10 oz for desk use and the Travel Mug if you're always on the go. The 14 oz is great if you just want a bigger cup.
