I ended up giving the Ember Mug to my buddy at work and he loves it because he has a small coffee maker on his desk and pours the steaming hot coffee directly into the mug. When it’s all said and done, the Ember Mug is a nicely made product but needs to have a larger capacity and at least double the battery life before I would recommend it. But, the cup warmer can be used with any mug including my favorite glass mug which I can use in the microwave to boil water to brew my tea. Disclaimer: I’ve never used a cup warmer plate, so I don’t know how well they really work. But then I can also buy a cup warmer like this one from Amazon for less than $10. Sure, I could just place the Mug on the charging saucer and not worry at all about battery life. Unfortunately, the fact that the mug doesn’t hold that much liquid and the battery life is too short makes the Ember Mug an expensive novelty item. I had high hopes for the Ember Mug at work and thought it would be the perfect solution to my lukewarm tea woes. Just set the mug on the saucer to charge.
Perfect hot beverage temps from the first drink, to the last drop.I finally got frustrated and stopped using the app altogether since I am fine with the default temperature setting of 130° F degrees. Almost every time that I would launch the app, it would not reconnect to the mug. What is a big deal is that the app loses connection with the Mug and it has to be paired again when you want to use it to check the temp or customise it.
The app reports a higher temperature than my IR thermometer. I also installed the Ember app so I could compare what it thinks the beverage temps are vs. For my next test, I went with green tea which can steep at the temp out of the hot water machine. I then set the mug on the saucer to charge it.
126° F degrees 5 mins later and the cup is empty. 123.5° F degrees 3 mins later – The status LED is pulsing to show that the contents are below the desired temp. 130.5° F degrees 10 mins later – The status LED glows solid white to show that the desired temp is achieved. The status LED starts pulsing white to show that the temp is either over or under the desired temp. Transferred water to Ember Mug with a teabag. Microwave glass mug of water 1.5mins to a temp 185° F degrees. 160° F degrees out of water machine in a glass mug. Here’s a history of the temps using the Ember Mug and an IR thermometer which I pointed straight down into the center of the mug. Problem #1: The Mug’s true useable capacity is only about 8-ounces instead of 10-ounces and Problem #2: I made a mess pouring water from the glass mug into the Ember Mug. Once the water was boiling, I put the teabag in the Ember Mug and dumped the water from my 10-ounce mug into the Ember Mug. I filled my glass mug with water and put it in the microwave to boil the water. Since you can’t put the Ember Mug in the microwave to heat the water to boiling, which is what I have been doing several times a day with a traditional mug when I’m at work. I do have access to a hot water machine, but the water is only 160° F at its hottest, which isn’t the right temp for brewing the black tea that I prefer. The next day I took the Mug to work with me and that’s when more problems with this product started becoming apparent to me.įirst of all, at work, I don’t have access to boiling water like I do at home. I was surprised that the mug’s battery only lasted for 60 minutes because the tea in the mug was hotter than the set temp, meaning the mug was not having to use any juice to keep the tea at the right temp. The only troubling thing that I noticed was that the LED on the mug started glowing red after an hour to let me know that the battery was getting low. I didn’t have to get up and reheat the tea in the microwave which helped me improve my couch potato skills. Every time I wanted a sip, the tea was still hot which was great. I waited a few minutes, removed the tea bag and moved to the couch where I sipped the tea for 90 minutes or so. I boiled water on the stovetop like I always do and poured the water into the Mug over a tea bag. The first time I used the Ember Mug was at home before installing the app. The app has temperature presets that you can choose for different beverages, or you can choose any temperature from a minimum of 120° F to a maximum of 145 ☏.
