A split bottle warmer is disclosed, which relates to the technical field of maternal and infant supplies. The bottle warmer includes a base and a heating module detachably arranged on the base for connecting to a bottle mouth, the heating module is configured with a heating element. The base is configured with electro-contact parts, the heating module is configured with conductive parts plugged into the electro-contact parts, the heating module is configured to be electrically connected to the base when the electro-contact parts are plugged into the conductive parts, and a positioning structure is configured between the conductive parts and the electro-contact parts. By setting the conductive parts and the electro-contact parts, the split bottle warmer can realize circuit conduction and thereby having advantages of removable the heating module and the base.
