The KOPI Mug is a smart, all-in-one self-warming mug plus brew system. Made from super durable ceramic, KOPI’s base is inlayed with metallic particles that respond to an electric charge. When KOPI is placed on its wireless (water/spill resistant) charging pad, the particles react via electromagnetic energy and heat your beverage to the perfect sipping temp. Plus KOPI uses wireless Qi technology, so it can juice up all your smart devices too.
