This smart mug is probably superfluous. It has a smartphone app that notifies you when your coffee reaches the ideal temperature, and its onboard light also provides a visual indicator that your brew is ready. It intelligently adjusts power usage to keep your drink hot when you’re around, and turns it off when you’re not. The self-heating mug is on sale in a few variations – 10 or 14 ounces, in blue, white, black and purple.
