Q: Are there lids for ember mug?
submitted by Rosa - 4 years ago
A: no lids. I put a silicone lid on mine if my coffee sits for awhile. this extends the length of the charge.
submitted byRobshop - 3 years agoA: Ember now has lids for both the 10oz and 14oz ceramic mugs! The great thing about the lid is it not only helps prevent spills, it doubles the life of the battery!
submitted byBrand Expert - 2 years agoA: Hi there! We currently don't have lids for the Ember mug at this moment, (Just our Travel Mugs). We'd be happy to pass this interest along to our team!
submitted byEmber, Inc. - 4 years agoBrand expertA: Don’t buy from this company. Mine died after 4 months and they never responded to my many requests for help or a replacement

Q: Does the white version stain at all, and if so is it easy to clean/remove the stain?
submitted by Matt - 5 years ago
A: Hi Matt, thanks for reaching out! For best care and maintenance, we would recommend rinsing your mug with water soon after finishing your beverage to avoid letting it sit on the paint for too long. For best results, we also recommend hand-washing the Ember with warm water, mild dish soap, and a soft sponge.
submitted byEmber, Inc. - 5 years agoBrand expertA: I have two white mugs. both are stained and I do take care of them. I will not buy the white again. other than that, I love the ember mugs.
submitted byRobshop - 3 years agoA: Mine stained in about a month. And I rinse mine every day I use it and probably a handwashing once a week.

Q: Is the inside of the mug ceramic lined or stainless steel?
submitted by Mama405 - 1 year ago
A: The Ember Mug is constructed with solid food-grade stainless steel and has a proprietary ceramic coating that gives it the look and feel of a classic ceramic mug.

Q: Does this fit into a cup holder in a car?
submitted by Bsharp - 1 year ago
A: While the Ember Mug may fit in some vehicles' cup holders, it is designed of home or office use and don't recommend using it in your car as the Mug doesn't include a leak-proof lid and may spill. Instead, we recommend our Ember Travel Mug, which is designed to fit in most cup holders, includes a leak-proof lid, and even has an optional (purchased separately) car charger designed to fit in your cup holder and keep your Travel Mug at your perfect temperature for even longer.

Q: On my copper mug the copper color has chipped off on the bottom. Not all the way but 2 scrapes I am concerned I’m ingesting copper particles.??? Very concerned
submitted by Lisa - 2 years ago
A: Sorry to hear you are having an issue with the Mug's coating. Reach out to our team via email at support@ember.com. Rest assured the mug/its metallic coating are FDA-approved food-safe and non-toxic

Q: What is the country of origin?

A: Country of origin is China.

Q: Is it safe to pour boiling water directly in this mug? For example, i boil water and want to make a cup of tea. i'd normally pour between 190F to 200F water directly in the cup to steep the tea bag...
submitted by Dane - 2 years ago
A: The recommendation is to use hot water, not boiling as the boiling water could overheat the battery.
submitted byBrand Expert - 2 years ago
Q: Do you have to sign up for an account to begin using this device? If so, do I have to consent to data collection like location services?
submitted by Liberty - 2 years ago
A: The Ember Mug App does require an account to adjust the set temperature, however the Ember mug will heat to the default set temperature of 135F without the app. Android does require location services to be turned on for bluetooth. We also have an option to opt out of sharing data with Ember.

Q: How does the battery recharge? USB or plug?
submitted by eileen - 5 years ago
A: Hi eileen, thanks for reaching out! Each Ember Mug is sold fully packaged with a charging coaster included, along with a US 2-prong power source wall plug-in that can accept anything between 100VAC and 240VAC.

I would like this coffee milk. I don’t like the fact that they didn’t come with a cover. I needed it for my office space because I didn’t have a spilled proof or recover it towards my downside.

Garbage
This product is just frustrating. I spend more time fussing with it, the bluetooth connection and just trying to get it to turn on and figuring out what pattern of lights means just on. I have to re-pair the thing every time I open the app I think all the options and the app might be great if you had a product that actually worked

Needs work on the ceramic
I received this cup as a gift in October. I have the white one. Unfortunately, from using a spoon, the whole bottom the ceramic is gone. The metal is showing through.Couldn’t get any help because I didn’t have a receipt to prove it. The cup worked great for about nine months and then it just wasn’t working properly. Make sure to use a wooden spoon if you were going to stir anything into your beverage..

Worthless…max temp is 145
Worthless! Mug won’t heat above 145…I still have to heat my coffee in the microwave in a separate mug every 30 mins to reach my desired temp of 165.

Gimmick coffee cup
It's a gimmick item. Works great for a while, but when the rechargeable batteries reach end of life, you're stuck with a coffee cup that's just like any other cup, except it shouldn't go in the dishwasher. Plus, the flimsy pins on the recharging pad - do take care in setting down the cup to charge, and keep the bottom of the cup very clean. Poorly designed/very fragile. Overall, the fact that you cannot easily replace the rechargeable batteries is a major turn off for every buying these again. Would also add a ding on the cup volume - using a K-cup on a small/medium/large type of Keurig, there is very little room for adding anything when using large (12oz).

Used
I was very excited to get this for my husband for Christmas. Unfortunately, when I opened the box when it arrived, the Ember container itself was completely apart, and everything inside was splayed about the box. Upon reviewing the product itself, it appears to be used. There is a lip mark around the rim and a ring on the coaster. I plan to go to the store and inquire about an exchange. If not, I plan to return.

Flaking coating - gently used
I have issues with the coating flaking off on the inside. I've always hand-washed the mug and only use plastic utensils. it's only been a few months and very disappointed with the flaking coating.

Bad shipping?
Ordered this as a gift. When it arrived it seemed as though it had been opened and thrown back together. Pieces were not in the box and the mug itself was dirty. Disappointed.

Nothing but issues
Doesn't charge past 75% and have to repair the mug to the app every time I turn it on. Seems I'm not the only one who has the issue according to all the reviews on the app.

Toxic mug?
I like the idea but there are two problems with the mug I got. First, the charging pins stick so that you can't make good contact between the coaster and mug to charge. I had to try a fix this with a dab of solder to raise the pin higher. Second, after a few months the coating started to come off. At first I was not concerned but then after using it for several more months I went to clean it out (hey hot coffee-- I just rinse) and all the coating came off the inside. So apparently I was swallowing the paint all this time. They claim it is ceramic, but ceramic would not peel off the way this stuff does.

Never reconnects to app :(
Disappointing app experience. After the initial pairing the app will never connect to the mug. (Pixel 9 pro xl) You may think you don't need the app - but you do if you want to view battery life or change the temperature set point. One star based on this being a premium product at a premium price. Bugs like this are unacceptable at this price point.

So Happy!
⭐⭐⭐⭐⭐ Ember Mug – The Best Gift I’ve Used All Year I received my Ember Mug for Christmas in 2024, and after using it consistently for almost a full year, I can easily say it’s one of the most useful and well-designed gifts I’ve ever owned. From the very first day, it completely changed my morning routine. Instead of rushing through my morning drink before it cools off—or having to reheat it multiple times—I can set the exact temperature I enjoy and keep it there. It feels like having a tiny personal barista carefully maintaining my perfect cup. What I love most: Consistent temperature: My morning drink stays exactly how I like it from the first sip to the last. No reheating. No guessing. Just perfect. Beautiful design: Sleek, modern, and comfortable in the hand. It feels premium every time I use it. Long-lasting battery: I’m impressed with how long it holds a charge, especially after nearly a year of daily use. Smart features that actually matter: The app works smoothly, the temperature control is effortless, and everything feels intuitive. Surprisingly durable: After almost twelve months of use, it still works like the day I opened it. I didn’t realize how much a mug could improve my daily routine until I owned this one. Now I wouldn’t want to go without it. If you’re on the fence about buying it—or considering it as a gift for someone—you'll be glad you purchased it. Easily a 5-star product. One of my favorite gifts ever.

One Year Review
I've had this mug for about a year and use it at least 3 times a week. It works like it is intended to and I have had no issues.
