A portable refrigeration apparatus includes a base defining an open interior cavity. An electric refrigeration unit is operably disposed in the base for cooling the contents of the interior cavity. A food container is configured to be removably disposed within the interior cavity of the base such that the cooled air is prevented from entering the food container and instead is trapped and circulated within the interior cavity surrounding the food container. A lid is positionable over the food container and configured to be removably placed onto an upper edge of the base or onto the food container to form a generally air-tight seal therebetween.
