A heated coaster so slim it barely takes up desk space.

Plug this coaster into your laptop or any USB charger and set your mug on top. The aluminum plate passes warmth straight into the cup, keeping coffee or tea comfortably warm. At just 0.6 in (16 mm) tall and about 4 in (103 mm) across, it slides in next to your keyboard without fuss.

Why you'll love it

  • USB powered: Runs from a laptop port, USB charger or power bank.
  • Aluminum plate: Warmth moves quickly into the base of your mug.
  • Ultra slim: Only 0.6 in tall, so it never feels bulky.
  • Wood or black: Choose light wood, dark wood or matte black.
  • Easy to use: Just plug it in and set your cup on top.

Perfect for: laptop desks, dorm rooms, reading corners and stocking stuffers
