Who it's for

This intelligent tumbler is crafted for professionals and travelers who demand consistent quality and modern convenience.

Key features & specs

The following table details the core technical attributes of the Ember Tumbler.

How it compares

Compared to standard vacuum-insulated flasks, the Ember Tumbler actively heats the liquid rather than just slowing down heat loss, ensuring the last sip is as hot as the first. In contrast to cheaper electric mugs, Ember offers a premium ceramic finish that prevents a metallic aftertaste, a common issue in lower-end travel mugs. The addition of a leak-proof lid makes it more versatile for travel than the original office-style Ember Mug.

How to use it

1. Charge the heart of the tumbler using the included charging coaster until the LED indicator turns green.
2. Pour in your hot beverage and use the Ember app to set your precise preferred temperature.
3. Secure the 360-degree leak-proof lid before placing it in your bag or cup holder.
4. Monitor the temperature and battery life directly from your smartphone or smartwatch.
5. Hand wash the tumbler only; do not place it in the dishwasher to protect the internal battery.

Finally, a travel mug that actually stays at the exact temperature I like; it has made my long commute much more enjoyable. — Verified buyer

Frequently asked questions

Is the Ember Tumbler worth it?

Yes, the Ember Tumbler is worth it for anyone who reaches the end of their drink only to find it lukewarm, as it guarantees a perfect sip every time. The luxury of control justifies the price for daily users.

Does the tumbler work without the app?

Yes, the Ember Tumbler functions at a default temperature of 135°F without the app, though the app is required for custom settings. You can adjust the heat easily via the interface on the mug itself if needed.

How does it compare to a Yeti tumbler?

Unlike a Yeti which is passive insulation, the Ember Tumbler is an active heating device that regulates temperature to your exact preference. While the Yeti is more durable for rugged outdoor use, the Ember is superior for precise heat control.

Can you put it in the dishwasher?

No, the Ember Tumbler must be hand-washed because it contains sensitive electronic components and a lithium-ion battery. Submerging it in high-heat dishwashers will damage the internal circuitry.
