Little did you know your mug could be doing so much more. This ceramic mug isn't just a pretty face—it keeps your drinks hot for as long as it takes you to finish them. Metal particles in the bottom of the mug interact with the matching base beneath to keep your favorite liquid at a toasty 130°F. And the best part? When the base isn’t heating your mug, you can use it to charge your phone or wireless earbuds.
