Keep your drink at a comfortable drinking temperature all day Maintains coffee, tea or milk between 120–140°F (40–60°C) to slow cooling and reheat drinks so you can sip anytime without reheating. Continuous temperature hold: designed to keep beverages in that range throughout the day. Safe, automatic operation Microgravity induction automatically turns the warmer on when a mug is placed on it and off when the mug is removed. Activation requires the mug to weigh more than 0.8 lb (13 oz). Simple plugin operation: plug the adapter into an outlet, place your mug, and the unit works automatically. Designed for real cups and daily use 3.5' (≈9 cm) diameter heating area fits most cups: glass, stainless steel, ceramic, and more. For performance use a flatbottom glass or stainless steel cup; using a lid will help retain heat. Surface is covered with a layer of thermally conductive glass that's waterproof for protection against occasional spills and easy to clean.
