Abstract: A quick-disconnect USB-driven ceramic electric heating apparatus includes a round base, a circuit board and a heating element. The round base is provided with a USB socket for receiving an external USB-based power supply that supplies power so as to have advantageous of power saving and low heat generation. The round base has a plurality of elastic barbed latches that allow the round base to be inlaid to holes of different sizes on ceramic devices. The heating element is a heater in form of flexible film and has an adhesive surface for adhering the heating element to the ceramic product so as to provide quick and direct heating to a specific portion of the ceramic device.
