What looks like just a traditional coffee mug is actually a problem-solving tech innovation. Using electromagnetic energy, the Ui Self-Heating Ceramic Mug keeps your favorite hot beverages at 130°F for most of the day with its mug and heating coaster. The coaster also doubles as a charging pad for Qi-enabled smartphones. The coaster should be cooled-down before it’s used for charging. 


Features of the Ui Self-Heating Ceramic Mug include:

  • Keep your hot beverages at a steady 130°F when the mug is on the coaster.
  • Bone ceramic mug.
  • Includes heat-retaining ceramic lid when you need to take the mug away from the coaster.
  • Coaster powered by USB port and included standard plug-in power adapter. (Needs to be plugged in while in use.) 
  • The coaster is spill-resistant so no need to worry about any spills.
  • Coaster doubles as a wireless charger for Qi-enabled smartphones. 
  • Charger is made from anodized aluminum alloy & tempered glass.
  • Turns off automatically if you don’t pick up the mug for an hour.
  • Mug is dishwasher-safe.

Why We Chose This
For its dual functions of beverage-warming and phone-charging, Kopi uses AEE (Advanced Electromagnetic Energy). Part of this technology involves inlaid metallic particles within the base of the mug for self-heating and also in the mug's coaster—which facilitates warming and also charges your phone after the coaster has cooled down.
