Ember Mug², 14 oz

Consistently Warm Coffee

If your wake-up routine relies on a cup of coffee or tea, listen up. Those first steaming-hot sips are bliss, but then life and science come into play, and before you know it, your perfectly hot drink is a tepid, lukewarm brew (faster if you add dairy). So you zap your mug in the microwave (which likely results in bitter, astringent coffee) or quickly drink it down before it gets any cooler. Neither is very appealing. Smart mugs, which often work with a smartphone app, can reportedly keep a hot beverage at a specific temperature for an extended period of time.

"Worth its weight in gold for the practical cook who wants to feel confident about putting good food on the table."

Performance

Cleanup and Durability

This smart mug is simple to set up and easy to use, and when used with its app, it is the most accurate model we tested. It kept coffee at the temperatures we set for an average of 70 minutes and within our ideal temperature range of 130 to 160 degrees for an average of 90 minutes. We liked that the app sent an alert when the coffee had reached our set temperatures. It charged in just 2 hours, one of the shortest charging times in our lineup. We also liked its built-in safety features; it automatically “sleeps” when it’s empty or after 2 hours of inactivity. If you don’t have a smartphone, you can still use this mug: It’s programmed to maintain a temperature of 135 degrees, though when we tested this function the temperature remained closer to 130 degrees.
