Some people slurp their coffee while it’s piping hot, others warm their hands with it till it cools to a drinkable temperature. A smart mug called Ember aims to keep it at the perfect temperature for two hours using a rechargeable battery.
A touch sensitive logo indicates the temperature at which your java is resting, while turning the ring at the bottom lets you adjust that up or down. Apparently, most people enjoy their cup of joe at about 135 to 140 degrees Fahrenheit. A pop-up lid means you can drink from any direction without searching for the opening.
Pre-orders for the Ember cost $129 and delivery is expected in May.
