It’s a chilly Sunday morning. You pour yourself a cup of tea, curl up in a cozy blanket, grab a book, read a few pages, and take a sip only to find that the coffee’s gone cold. This letdown is precisely why Ember–an L.A.-based startup that makes temperature-controlled products–designed its latest offering: the Ember Ceramic mug.
The smart mug, which was designed by Ammunition, connects to your phone through Bluetooth and allows you to set an ideal temperature for whatever you’re drinking (up to 145 degrees Fahrenheit). Once the beverage reaches that temperature, the mug will maintain it for up to eight hours. On the outside it looks just like a regular cup, but beneath its unbreakable double-walled stainless steel and ceramic exterior, there’s complex tech making this seemingly simple feature work. Four sensors embedded inside relay temperature info to a microprocessor in the cup’s base, which tells the heating element to crank it up or dial it back. To recharge the cup–which is hand-wash only, obviously–simply rest it atop the included conductive coaster.
