The Best Smart Mug: Ember Mug², 14 oz
The Ember Mug², 14 oz is our favorite smart mug. It’s easy to use, and its temperature settings are accurate. Simply download the app, pair your device, set your desired temperature, and enjoy your coffee. If you don’t want to bother with the smartphone app, this mug is automatically preset to maintain a temperature of 135 degrees. However, we discovered that on this automatic setting the coffee temperature hovered closer to 130 degrees (both while the mug was positioned on its coaster and while it was off). This wasn’t a deal breaker for us. We loved that its battery charge lasted long enough for us to enjoy coffee at a set temperature for 70 minutes and within our ideal range for an average of 90 minutes. When placed on its charging coaster, the mug is capable of keeping coffee hot for 5 hours, but we don't recommend heating a single cup for longer than 90 minutes because its flavor will deteriorate. This mug was the most precise model we tested, and it took us just 2 hours to fully charge it, one of the fastest times in our lineup. And its smooth ceramic-coated stainless-steel walls and comfortable handle make the mug a pleasure to drink from. This mug extends the time we have to savor coffee or tea at our desired precise temperature. At roughly $130, this high-tech mug isn’t cheap, but the convenience it provides is unmatched.
