Temperature-adjustable Ember coffee mug is hot on Indiegogo

With Ember Technologies' new Ember mug, you set the temperature of your beverage using an app on your phone.

The Ember mug, which will retail for $150, ships in April 2016.

Ember Technologies is touting its upcoming Ember as "the world's most advanced mug." The mug, which is scheduled to ship next April, is being sold on crowdfunding site Indiegogo for $130, which is a $20 price break from its expected $150 retail price.

Sounds like a lot of money for a mug that keeps your coffee warm, but the company has blown through its goal of raising $50,000 in presales and now sits at over $200,000 with close to two weeks left in its campaign.

Inside the mug is a "precision temperature control system" that allows you to cool down scalding hot beverages and warm them to an exact temperature for up to two hours. (Of course, whether or not you should warm up or reheat coffee remains controversial among java devotees.) The mug comes with its own charging dock and can be controlled from an iOS, Android device or Apple Watch via Bluetooth. Needless to say, the mug needs to be washed by hand.

Ember is designed by Ammunition, the same firm that designed Beats headphones and the recently announced Savant Remote and plenty of other consumer products. Ember's CEO Clay Alexander stopped by our New York office to show us the mug. He had some prototypes of other Ember products on hand, including a temperature-adjustable baby bottle and plate, but didn't want us to photograph them because he didn't want potential competitors seeing their designs.

"The mug is just the first product in a line of temperature-adjustable products," Alexander said, showing me a book filled with patents that he'd been working on for several years. "We have a lot more stuff in the pipeline."
