A portable ice chest used for maintaining its contents in a cooled or frozen state for an extended period of time. The ice chest includes an insulated cover with an inner compartment and an insulated container with a bottom compartment. The cover is adapted to fit airtight upon the top opening of the container. To maintain the contents of the ice chest in a frozen state, a refrigerant coolant such as dry ice is placed in the inner compartment only. To maintain the contents of the ice chest in a refrigerated state, a refrigerant coolant such as dry ice is placed in the bottom compartment only. Additionally, when no dry ice is placed in either compartments, the present invention can be used as a regular ice chest.
