A novel portable thermoelectric cooling and heating food appliance adapted for use in a vehicle by travelers, hunters, and campers. A base unit is provided which can be connected to the cigarette lighter receptacle of the vehicle and with the use of thermoelectric Peltier elements offer through a selective cool or heat control circuit the cooling or heating required of any of several kinds of appliances that can be detachably attached to the base unit and adapted through cool and heat conducting transfer plates to cool or heat the appliance and the foods or liquids therein and upon removal of the appliance from the base unit the bottom of the appliance is closed by a slide cover to cover the bottom conducting plate of the appliance so the food or liquids will be kept in the cool or heat condition. Ice cubes can be made by drawing cold air from the air conditioner vent of the vehicle to be passed over the active elements of the base unit and at the same time provides means for further cooling ambient air about the appliance and in the vehicle.
