Flat Bottom Steel Mug Compatibility Designed specifically for flat bottom mugs to ensure maximum contact with the heating surface. For results, place your mug so the entire bottom rests evenly on the plate. This unit is not intended to act as a heater for keeping beverages extremely hot but rather to maintain a desirable drinking temperature. Three Adjustable Temperature Settings Features three thermostat options that let you slow down the cooling of your favorite hot drinks. Choose a gentle warmth to maintain your beverage just above room temperature, or increase the setting to enjoy a toastier drink at up to 280°F. Durable Metal Waterproof Heating Plate Constructed with a metal heating plate that resists damage from spills. The spillproof design helps protect the warmer's components, unlike many plastic models that can be damaged by liquid contact. Safe and Stable Base Equipped with four nonslip feet to keep your mug secure and help prevent accidental tipping or spilling during use. Ideal Uses Keep coffee warm during long work sessions at your desk without reheating. Maintain tea at a pleasant sipping temperature while reading or relaxing. Preserve the warmth of hot cocoa during cold evenings without worrying about rapid cooling.
