Ember Smart Mug 2 Review 2025: The Best Smart Coffee Mug That Keeps Drinks Hot

I never thought I’d spend over $100 on a mug.
I mean, mugs are supposed to be the freebies you get at tech conferences, right? You know the ones — ugly logo, weird handle, mysterious chip in the glaze.

But then came the incident of 2024. Picture this:

• I’m on a video call, looking professional-ish (aka wearing a hoodie but brushed my hair).
• I reach for my coffee…
• It’s stone cold. Again.

And like a true adult, I muttered: “That’s it. I deserve better.”
That’s how I justified the splurge on the Ember Smart Mug 2 — this smart coffee mug that promised to end my lukewarm coffee suffering.

📦 Unboxing: Fancy Mug, Fancy Feelings

Unboxing Ember feels more like unboxing a new iPhone than a kitchen item.
The mug sits in the box like it’s saying: “Yes, I am a piece of art, please admire me.”

Inside you get:

• The mug (obviously).
• A charging coaster that looks like it belongs in a sci-fi lab.
• A cable you’ll immediately lose behind your desk (at least it’s USB-C now).

---

☕ First Impressions

At first glance, Ember is just… a mug. Matte black, ceramic, kind of minimalist chic.
No blinking lights, no obvious buttons.

But here’s the magic:

• Pour in coffee.
• Pair it with the app (took me all of 30 seconds).
• Set your temperature. Mine is 59°C — hot enough to feel cozy, but not hot enough to scorch my tongue (learned that the hard way).

From that moment on, Ember basically says: “I’ve got you, girl. Sip whenever.”

🔋 Living With Ember

Now, here’s the truth: I am easily distracted.
Emails? I’ll answer one and then spiral into reorganizing my entire Google Drive.
TikTok? Don’t even ask.
My coffee? Forgotten on the desk.

But now? I come back 20 minutes later, and it’s still warm.
I come back an hour later — if the mug was on its charging coaster — and it’s still perfect.
It’s like Ember knows I’m unreliable but loves me anyway.

😅 Funny Story #1: The Haunted Mug

One Saturday, I handed the mug to my best friend without telling her what it does.
She took a sip, frowned, and whispered:

“Uh… did you just pour this? It’s too hot for how long it’s been sitting here.”

Then she grabbed the mug and inspected the bottom like it was a UFO.
I told her the truth, and now she won’t stop sending me links to “smart mugs for cats.”
(Which, to be clear, do not exist… yet.)

😅 Funny Story #2: Cat vs. Mug

Speaking of cats: my fluffy overlord, Pixel, has decided that the charging coaster is his personal heated throne.
So now, whenever the mug isn’t on it, guess who is?
Yep. A smug cat.

📱 Temperature Control Mug App Experience

The Ember app makes this temperature control mug surprisingly smart:

• You can save multiple presets (coffee, tea, hot chocolate)
• It sends you notifications like: “Your drink is ready at 59°C”
• You can even name your smart coffee mug. Mine is called “Mug Life” because… why not

Do I need an app for my mug? No.
Do I enjoy watching my caffeine stats on a graph? Absolutely yes.
