Ember Tumbler 16 oz — Smart Temperature Control Travel Mug

$179.95 16 oz · Stainless Steel · Bluetooth App-Controlled · Two Lids Included
Your Coffee, Your Temperature. Every Single Sip.
Most insulated tumblers keep your coffee "hot" — but hot isn't always right. Too hot and you're waiting. Too cool and you're disappointed. The Ember Tumbler solves this completely. Set your ideal drinking temperature anywhere from 120°F to 145°F via the Ember app, and your coffee stays exactly there from your first sip to your last.
Whether you're pulling a morning espresso at home, heading into a long commute, or just settling into a slow work-from-home morning, the Ember Tumbler adapts to how you actually drink coffee — not the other way around.
Why the Ember Tumbler Belongs in Your Coffee Routine
- Precise Temperature Control (120°F–145°F) — set your exact preferred temp down to the degree. Never too hot, never lukewarm.
- Up to 3 Hours on Battery, All Day on the Charging Coaster — use it untethered on the go or keep it on the coaster at your desk for unlimited warmth.
- Ember App Integration — set temperature presets, customize your LED indicator color, receive a notification when your drink hits your perfect temp, and use the built-in steep timer for tea.
- Two Lids Included — choose the leak-proof Handle Lid for carrying or the spill-proof Sliding Lid for sipping. Both are dishwasher safe.
- IPX7 Waterproof — rated for full submersion up to 1 meter. Easy to hand wash or rinse without worry.
- Auto Sleep Technology — intelligently senses when your cup is empty or inactive and powers down automatically to preserve battery.
- Advanced Bluetooth Chip — Ember's most reliable Bluetooth connection yet, with a simplified pairing process.
- Premium Textured Stainless Steel — durable, scratch-resistant, and surprisingly comfortable to hold without a handle. Fits most car cup holders (3.5"+ diameter).

FAQ Section
How is the Ember Tumbler different from a regular insulated travel mug? Standard insulated mugs slow cooling but can't control temperature. The Ember Tumbler actively heats your drink and maintains your exact preferred temperature — meaning your last sip is just as perfect as your first.
Do I need the app to use the Ember Tumbler? No. Out of the box it's preset to 135°F and works without the app. The Ember app (iOS & Android) unlocks custom temperature settings between 120°F–145°F, LED color personalization, notifications, and a steep timer.
How long does the battery last? Up to 3 hours unplugged at 135°F with hot liquid poured in. Lower temperature settings extend battery life; higher settings may reduce it slightly. On the included charging coaster, it runs indefinitely.
Is it safe to submerge or hand wash? Yes — the Ember Tumbler is IPX7 rated, meaning it can be safely submerged in up to 1 meter of water. Both lids are dishwasher safe. Do not microwave.
Does it fit in a car cup holder? Yes — it fits most car cup holders with a minimum 3.5" diameter.
What temperature range can I set? Via the Ember app, you can set any temperature between 120°F and 145°F. Without the app, it defaults to 135°F.
