Nothing in the world compares to the feeling of a hot coffee, that small pleasure that accompanies us from first thing in the morning until the afternoon, at various times. However, maintaining the ideal temperature is complicated. At first, it’s boiling hot enough to peel a chicken, but then it can go cold in a matter of a few minutes.
Whether you’re at home or in the office, working or enjoying a moment of relaxation, a smart mug we found at Best Buy may be your next best friend for controlling coffee temperature. You will never again have to worry about a coffee that cools down too quickly, or one that is excessively hot.

Never Again Lukewarm Coffee — This Is How the Best Buy Emberg Mug 2 Works
For coffee lovers, the advantages of the Emberg Mug 2 are many. It keeps coffee hot for almost the entire battery life (as we said before, up to 1.5 hours in the small version), and it doesn’t need a lid to keep the liquid at the right temperature. The Emberg Mug 2 keeps coffee hot using a heating plate built into its patented base, created by technology entrepreneur, Clay Alexander, who holds more than 200 patents for cutting-edge inventions.

The first Ember was launched in 2010 and, in 2018, Alexander attracted the attention of singers Nick and Joe Jonas, of The Jonas Brothers, who put significant capital into developing the Emberg Mug 2. The system is quite ingenious: the sensors distributed throughout the heating base they constantly monitor the temperature of the liquid, and detect if the drink is cooling to gradually raise the temperature and thus keep it warm.
By default, the mug comes set to keep the liquid at 135°F (57°C), but you can adjust this using the user-friendly Ember app. The temperature range is from 120°F to 145°F (50°C to 62.5°C), and the app notifies you when your coffee or tea is just right, although you can also choose to turn off notifications if you prefer not to receive them.
The App Is Pretty Easy to Use
The most striking thing about Ember mugs is how easy to use it is, both the mug itself and the app. No one wants a smart mug that requires you to read long instructions or has too many settings that force you to keep an eye on your phone.
Fortunately, setting up the Ember mug takes just a couple of minutes: you download the Ember app, pair it with your mug, and that’s it. Then you just have to turn it on, fill it, and enjoy.
