Ember - Temperature Control Travel Mug - Matte Black

I wanted to like this product. The more I use it the less I like it. The good: it does heat up the coffee, it is sturdy, does not leak, looks nice. The bad: heats up slowly. For instance, with creamer takes a while to get up to temperature si ve the cold creamer bring the coffee temperature down after it brews. It also thinks it’s empty when the coffee is there. Once it heats up and you open to drink the coffee splatters everywhere because of the pressure built up. Makes a mess. Your clothes will be splotched. I put my hand over it and of course all over my hand then need to wash off. If you’re driving this is bad. See what I mean. The battery will last enough to only heat the one time then Luke warm coffee if you don’t recharge. The charger works as expected with reasonable recharge time. A great concept but too expensive for so many drawbacks and I bought it on sale! I’ll keep a look out Ember. Ball is on your court. You can do it.

Hello All, Like most people here I like to explore new items that are cool that are designed to make life easy or better. In this case the price tag does not meet expectations. I bought both the Travel and Ceramic Mug and found that the Travel mug's battery discharged faster than the ceramic Mug. So I did some tests and sent it off to ember support to see if they can replace or repair my mug. Here are my results. Test 1 - Cold to Hot Both Mugs 100% Battery Liquids - 78 Degrees F Desired Temperature - 132 Degrees F Results: 30 Mins in to the test: Ceramic Mug - 65% Battery Travel Mug (With Lid On) - 0% Battery Test 2 - Maintaining a temperature Both Mugs 100% Battery Liquids - 141 Degrees F Desired Temperature - 141 Degrees F Results: 10 Mins in to the test: Ceramic Mug - 95% Battery Travel Mug (With Lid On) - 78% Battery 45 Mins into Test: Ceramic Mug - 50% Battery Travel Mug (With Lid On) - 0% Battery Working with their support team they claim that's the expected results about 1 hour of usage from the travel mug, and they where amazed how the ceramic mug was over performing… Well if the price of having a drink at the same temperature for less than an hour for $160 USD, then please count me out. I could by a decent travel mug that holds more liquid for under $60 USD. So thanks ember for wasting my hard earn money on a product that is not worth the price

The mug battery would die on my second cup of coffee. I suggest buying a thermal mug. Do not waste your money!

I bought it for my husband for Christmas. It worked for about two weeks and then it started displaying the ERROR message and has not worked since. We tried resetting it and everything. I've contacted Ember and I'm waiting to hear from them.

Originally I wanted to buy a white one but Best Buy only had black. I’m glad that I got the black one. The drink will stay at the temperature you select using the dial at the bottom of the cup or on the Ember app. Once charged it will cool the drink down to desired temp and maintain it there for approx 2 hours. However since I work at a desk I just leave the cup in the charging dock and it keeps it warm all day. I ended up buying two so I can have one at home too. My second one is white and it stains on the outside pretty quickly, wish I would have gotten a black one instead. One only thing is if you are traveling more than 2 hours, the battery will die and no way to charge it as there is no car charger for it. I’d be happy to change it to 5 stars when they come out with the car charger.

Has worked so far but the lid eventually stopped working (it wont stay open) and occasionally it just doesn't turn on even though it is at full charge. I have heard other people encounter this as well. Would not really be an issue if the replacement lids were in stock; but they arent... But I have to say. It works. I always used to have to throw away coffees because I would forget about them for 30 minutes and find them too cold. This solves that issue. Additionally this solves the issue of burning your mouth since it tells you the exact temp and will even send a notification to your phone when that happens. No more scared taste tests where you inevitably burn your tongue trying to see if its safe to drink. Don't get confused though, this is not something to heat up cold coffees. You can sometimes do that but it will tank the battery. I see a lot of people not look into this before buying it just to complain it doesn't do what it never said it did. I really hate the price, its really just a $20 peltier plate from Alibaba and (maybe) a $15 battery within a $10 aluminum mug. But because they somehow convinced the US patent office this was some original invention, no one but companies in Asia who are not subject to US law can make a competitor. Thus if you want the features I outlined above, you need to pay the egregious price.

This mug is shortlisted as one of my Favorite Things, right after my dog. It's so nice to make a cup of coffee and then get busy doing something else, and when I come back to it my coffee's still a perfect 140°, right where I left it. Also of great importance, I was an early backer on their crowdfunding campaign, and when one of their early prototypes failed, they couldn't have been quicker to replace it. Great people!

So I really wanted to love this, the idea of it is amazing but in practice it falls short. I bought two of these on sale, one as a gift and the other for myself that I eventually returned. The ember mug does an excellent job of either getting your coffee hot or keeping it hot but the one major downside it has, that eventually caused it’s return, was the battery life. With freshly brewed coffee at a temperature of 135F the mug would last around 1hr before the battery would called it quits. If connected to the proprietary charging base this was no problem but if on the go (or work in my case) this does become a bit of a pain. The battery issue would be less of a problem if the mug was better insulated. After about 20 or 30 minutes of the battery dying (with the included lid on and closed) my drink would already be noticeably cooler. If they improved the battery life, tweaked the insulation, and changed the charging base to be more universally compatible (QI) this would be a 5 star item. As is, I would recommend to wait for an updated version.
