Questions, answered

What you might be wondering.

Everything we get asked the most. If something's missing, we're a quick chat away.

Which Mug 3 size should I choose?
Choose 10oz Mug 3 for smaller pours, 14oz Mug 3 for everyday coffee, or 16oz Mug 3 for a larger serving. All three offer on-mug temperature control, an optional app, top-rack dishwasher-safe cleaning, and an included sliding lid.
Should I choose Mug 3 or Tumbler 2?
Choose Mug 3 for coffee or tea at home or at your desk, with a traditional side handle and a choice of three sizes. Choose Tumbler 2 for commutes, walks, and days on the go: its slim 16oz design fits car cupholders and includes a handle lid and sipping lid. Both maintain your chosen temperature and offer controls directly on the drinkware.
How long does the battery actually last?
Mug 3 keeps your drink warm for over 3 hours with the included sliding lid, or 80 minutes without the lid in this size. Use the included charging coaster for all-day warmth while you drink. Battery life varies with your temperature setting and ambient conditions.
Do I need the app?
No. With Mug 3, you can set your temperature directly on the mug. The optional Ember app for iPhone and Android lets you fine-tune your preferred temperature.
What is your return policy?
Unused mugs can be returned within 30 days of delivery. A $10 restocking fee applies; exclusions and instructions are in our Return Policy.
Is there a warranty?
The charging coaster included with Ember Mug 3 has a lifetime warranty. The mug has a 1-year limited warranty for manufacturing defects. Contact Ember support for warranty service.
Can I put it in the dishwasher?
Yes. Place Mug 3 on the top rack of your dishwasher, then let it dry fully before charging. Keep the charging coaster and cable out of the dishwasher.
How does Ember hold my temperature?
A heater and sensors built into the mug work together to maintain your preferred drinking temperature.
Will it keep cold drinks cold?
Mug 3 is designed to maintain hot drinks. The Ember Cold Tumbler uses insulation for cold drinks; it does not electronically cool them.
How long does shipping take?
Mug 3 includes free shipping. Orders generally leave our warehouse within 2 business days; delivery timing depends on your address and shipping method. See the Shipping Policy for details.
What comes with Mug 3?
Your Mug 3 includes a free sliding lid ($14.95 value), plus a charging coaster and charging cable. Choose 10 oz for smaller pours, 14 oz for everyday coffee, or 16 oz for more of your favorite drink.

I’m really enjoying using my

"I’m really enjoying using my Ember 3. It took a few days to get used to the sensation of my drink remaining hot but now it’s a relief and helps me enjoy my coffee longer. It’s so nice the mug is waterproof so I don’t need to stress about it getting damaged by spills. This mug is a special treat that makes a sweet difference in each day"

· Emily O. (5/5)

Overall I’m happy with my

"Overall I’m happy with my purchase. I am a little concerned about the life of the battery after it’s fully charged. I’m only getting about two hours at most before it alerts me to charge the mug again. I was expecting a much longer use time as I don’t always drink my beverage within that timeframe."

· Shannon H. (3/5)

Love the color - wish I could go back to 1 or 2

"I loved my Ember 1 and my Ember 2 and I figured, when it was time to get a new one, the latest and greatest would be the best. Nope. It's pretty. But, it takes way longer to charge and does not hold a charge nearly as long as 1 and 2. Ember sent me a replacement charger. It's different than the original but still charges slowly and the charge is gone before my coffee. :("

First of all, super slick

"First of all, super slick design! and the perfect size for my coffee. After figuring out how to use it (I personally preferred using the app, I found it a bit more difficult with the written instructions - especially with how to set the temperature) I tried it right away and was amazed how hot the coffee actually was, even after a long time (I used the lid). Highly recommended, I'm using it very day!"

· Yifat G. (5/5)

Seems like the coaster/charger seems

"Seems like the coaster/charger seems to be lighter and very unstable. It’s nice that the coaster/charger are guaranteed for life of the mug3. I’ve owned the Ember Mug, Mug2 and now the Mug3 x 2 each. Mine were always black. Wife had the bright Red one (Donation one), Sand and finally the Lavender one. Customer service is a bit difficult to find but once you get the right channel for customer service support things move quickly. Personally, I’d recommend the cup and will purchase the Mug4 or at least the new 16 oz cup."

· Jose A. (4/5)

If you tend to nurse

"If you tend to nurse a single cup of coffee over an hour while working or getting through a morning routine, this mug is an absolute game-changer. The 14 oz size hits the sweet spot for regular mugs without requiring constant refills, and the Salt Blue matte finish looks fantastic in person - clean, modern, and understated on a desk."

· Brian K. (5/5)

The perfect gift for anyone

"The perfect gift for anyone who go to work, work from home, stay at home moms and dads, teachers, doctors, pretty much everyone! Love the simple on the mug temp control, 3+ hours with lid temperature, amazing color options, and its dishwasher safe! Amazing!!"

· Elijah K. (5/5)

Generally I like my ember

"Generally I like my ember mug. This is the second one I've owned - the last one having come apart (the interior bottom) after around a year. If I had one suggestion, it would be that Ember build a cup that would withstand having something stirred in it. Out of 10, how many people don't add sugar, creamer or ?? that needs to be stirred?!? Each morning, I now make my coffee in another cup, add the sugar, stir it and then pour it into my Ember."

· John W. (4/5)

Dishwasher safe? Apparently not mine.

"Dishwasher safe? Apparently not mine. Now it's an expensive metal cup with a pretty purple light on the front. I should have stuck with hand washing!"

· Emily J. (2/5)

This is a very frustrating

"This is a very frustrating mug. It turns off after twenty minutes. I have verified the bottom and coster are dry. I have verified the pins are both up and free of debris. I have performed the reset. It will work for a day or so and then go back to shutting down. This is the third mug I have purchased. I wanted to be able to set the temperature without having to connect to my phone like the earlier versions. All I can say is this is very frustrating just to get a hot cup of coffee."
