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!

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. - 4 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.
submitted byNH - 3 years ago
Q: Is the inside of the mug ceramic lined or stainless steel?
submitted by Mama405 - 11 months 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 - 1 year 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?
submitted by WhereIsItMade - 2 years ago
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.
submitted byEmber, Inc. - 2 years agoBrand expert
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.

Slimy residue on coffee and cup
I like the mug but it has one drawback. I nurse my coffee in the morning and if you use half and half, the mug seems to “cook” the half and half leaving a brownish slimy residue on the coffee which transfers to the side of the mug interior. Wouldn’t have wasted the money if I knew this.

Design Flaw
This is great when it works. The charging pad is a bad design. The little spring loaded pins break or stick which then prohibits the mug from charging. It is a manufacturing problem, but they don’t care as long as it works until the warranty is up.

I loved it when it worked. After a month or two it stopped heating and the reset didn't work. It became useless

Just what I needed
Great cup for keeping my coffee hot. In your average mug, my coffee would get cold and I was reheating it on most days. I am delighted in coming back to a hot cup of coffee after getting breakfast started.

Not impressed
Second mug. This one is less than a year old and as with the first one not working no matter what I do. So will probably not get another one. Will stick with my Mr, Coffee mug heater.

Durability Concerns with Heated Mug Coating
I've been using this heated mug for just over seven months, and unfortunately, the coating at the bottom has begun to flake off. I’ve only cleaned it with mild dish soap and a paper towel, so I’m surprised to see this kind of wear. It’s disappointing, especially given the product’s price and intended durability. I also hope the materials used in the coating are safe and non-toxic.

Lifesaver
I had one years ago and burned it out, it worked great, it was so nice to have a hot cup of coffee consistently. Flash forward to a few months ago and we were prepping for trial. I was panicking because I wouldn't have my coffee. I purchased a new mug and it was an absolute lifesaver!

Nice that it keeps coffee hot but charger stopped
It will not connect to my phone so I can't adjust the temperature and the charger stopped working. Good thing my wife has one so I can take turns with her recharging it.

Loved it
I got this as a gift and loved it. But, although it still works well, I got it in red and the colour is chipping off inside & out! Not sure if it’s still safe to use.

Never reconneted
After constantly disconnecting from my phone, I deleted the app and reinstalled it. I ensured Bluetooth was functioning properly on my phone; however, I could never get the mug to connect. The lights on the mug flashed white-green-red ... nowhere on the website is this issue accounted for and I never got the mug to connect. Very frustrating and will never buy it again.

Cold and "empty"
It works occasionally. I have to fiddle with it endlessly to get it to start warming. Then it will shut off and say the cup is empty when it's completely full. And forget about trying to heat up half a glass, that will register empty every time and there is nothing you can do about it.

Feature Request
I Love the Ember mug, I've had mine for 5 Years and it's wonderful!!!......But i have a feature request! I would love a default setting with the Health X Ember setting, so I dont have to open the app for every cup of coffee to registrere the caffeine intake, thats so annoying!

Its Trash
I received the Ember as a birthday present in late September, and it’s now 10/29 — I’ve barely had it a month, and it’s already broken. I followed all the instructions carefully: hand washing only, keeping the coils dry, etc. Despite that, it won’t heat up or sense any liquid in my cup. I really wanted to love this, especially as a newly postpartum parent who relies on coffee, but every day I end up transferring my drink to a microwave-safe mug. Don’t waste your money — this is an overhyped luxury product that’s more trouble than it’s worth. Nothing will ever beat just a classic mug.

(no review title)
Item stopped working within 6 months. Reached to ember who stated the charger shirts when gets “damp” and offered to replace. Only offered a blue charger as black not available. Been waiting a month now and no replacement received. Start away from ember. Overpriced, defective and don’t back up The warranty.

Really Disappointing
The cup has a couple major issues. 1) the app frequently disconnects from the cup. You have no idea how irritating it is to constantly need to set it it up again when you just woke up. 2) battery doesn’t last long. It must be charged every day. 3) the cup is plastic. Nobody likes a plastic mug.
