Keeps my tea at the perfect temperature
This is my 2nd Ember Mug. I have this one at my office for a perfect cup of tea no matter how many interruptions after I make it!

Lasts only 1.5 hours if that on a 145 degree setting. Technically the battery should last 5 hours.

Hi Vijay, we do our best to let customers know what to expect from their Ember Mug's battery and are sorry for any disappointment. The Ember Mug (14oz) has an estimated battery life of approximately 80 minutes when used away from the charging coaster. Unfortunately 5 hours is not possible when the Ember Mug is in use and sustaining your perfect temperature. We recognize some customers may take longer to drink their morning coffee -- rest assured the Mug can keep your beverage hot throughout the day when used on the charging coaster. If the charging coaster is unavailable, we also have a sipping lid accessory which can double the expected battery life of your Mug. We hope this information is helpful and thank you for your feedback!

Wonderful cup!
This was a gift to me 2-3 years ago and I use it everyday, and still no problems! I'm careful to make sure the bottom is dry, don't submerge in water and it's been a great present . It does not keep my coffee piping hot for a long period of time anymore off the charger but that's been ok considering how old it is.

Ember 2 - A wonderful cup which I greatly enjoy!
Hi have an Ember 2 cup which I purchased as a Christmas present to myself in December 2024. It’s been in use since then every day and is brilliant at keeping my coffee warm. I’m careful to use a wooden spoon so as to not damage the cup’s coating and also to lift the cup off the charging saucer to dab-off condensation, being careful not to bend the charging pins. It’s a wonderful cup which I greatly enjoy using.

Too many defects
The connectivity is atrocious. I have to reset and re-connect every single time I try to use it. Which is frustrating if you've already setup your device multiple times. Also the battery drains so quickly. I get the charging coaster can be used but you'd think the mug would last longer considering it's a mug meant to keep your beverage warm...

Disappointing
Pretty disappointing. I have gotten two ember mugs as gifts. After my first one didn’t work 50% of the time my FIL bought me a new one. My new one malfunctions all the time saying the drink is empty or it’s 112 degree coffee when I have it set at 134. I really want to love this product because it’s genius but for the price I just don’t feel it’s worth it.

Beautiful and sleek design, but the battery...
I received the Ember mug as a Christmas present. Beautiful color and sleek design; however, there's an obvious flaw with the battery. Five minutes after being fully charged and removed from the charging coaster, the app displays 95% battery, and after forty-five minutes, it drops to 6%. It definitely fails and doesn't maintain temperature for 1.5 to 80 minutes.

Careful of easily spilling with rounded bottom
I've had this mug for a year and really love it. The only problem I have is the rounded bottom makes it so easy to tip. One slight push or nudge and it knocks over since the bottom is not flat. Mine charges fine and stays hot but I've knocked it over a few times by barely hitting it. Other than that mug is great. I don't use it for first cup of the day since I drink that one fast. But afternoon cup or a cup of tea to drink slow stays nice and hot. Nothing worse than taking a sip of cold drink that's been sitting a while.

Lid sucks cup ok
Stupid design on 16oz lid you cant tell if its closed or open or what side to drink out of. If you accidentally drink out of the wrong side coffee hits you in the eyes. It is worse early in the morning when its still kind of dark outside. Also you adjust the color but its never your color it stays mostly just white

Best gift!
This was given to me by my daughter because I was habitually allowing my coffee to get cold. I love this cup and have used it almost every day for several years.

Good Mug, Weak Battery
I like the mugs, but the battery life is terrible. 80 minutes for the large mug. and the battery drains when it's not being used. I charge it at 100% and overnight it will drop to 65%. Otherwise, it keeps my coffee hot and I like being able to regulate the temp. At the default temperature the coffee gets burned pretty fast. I keep it at 125º. Just need to beef up the battery life. Leaving the mug on the charger all dies sucks up electricity,

Disappointed
Got this at Christmas. Had to remove and re sync to Bluetooth every time I used it. Did not run while on the charging plate, and took nearly half a day to charge. Options were full refund or replace with a different color (no copper available at the time)

Company does not stand behind their product.
To all who purchase or own ember mug, beware, they do not stand behind their products. If something goes wrong. I've owned 2 mugs, and I had issues 3 times within a 1 1/2 year and they did not stand behind it twice, the mugs stopped working. And stopped connecting to your app. The heating plate stopped working, and now my mug again is not communicating with app and their resolution is will give you a discounted price

Worst app and makes mug useless
I got the mug and it worked for a few times in a short period of time. In recently months I haven't been able to connect it. I followed the available instructions and reset the app and data many times but the mug just sits on my counter wasting space.

Don't Waste Your Money
It stopped working 2 weeks after 1 year. Company was not helpful. They said after a year, buyer needs to pay for repair. Disappointing for the price point.

Defective
I have purchased two of these and for awhile (last one worked for only three months) and both have malfunctioned for the same reason. The pins on the coaster break down and will no longer keep the cup charged. When they worked they worked great. Unfortunately, they don't last very long before this defect renders them useless.

Not worth the money
The mug does not hold a charge long at all; 40 minutes or so. Definitely not at all worth the high price tag.
