• heating elements disposed to heat said first internal chamber, a battery, circuitry connecting power from said battery to said electrical heating source, an external terminal disposed to receive power from an external source and to conduct power from the external source to said heating source, a power converter disposed to receive alternating current power from said external source and to charge said battery from said power converter, and a switch for controlling said electrical heating source, said switch having an externally accessible control element;
• an upwardly open second internal chamber disposed beside said first internal chamber, wherein said heating source is arranged to heat only said first internal chamber when operating;
• a downwardly open chamber disposed beneath said first internal chamber and said second internal chamber, wherein said downwardly open chamber has a peripheral wall projecting below said floor of said first internal chamber and said second internal chamber;
• legs having means for moving between a stowed position wherein said legs are contained within said downwardly open chamber and a deployed position wherein said legs project downwardly from said downwardly open chamber when said first internal chamber is oriented to open upwardly;
• an upwardly open second internal chamber for carrying food disposed beside said first internal chamber, wherein said heating source is arranged to heat only said first internal chamber when operating;
• a downwardly open chamber disposed beneath said first internal chamber and said second internal chamber, wherein said downwardly open chamber has a peripheral wall projecting below said floor of said first internal chamber and said second internal chamber;
• legs having means for moving between a stowed position wherein said legs are contained within said downwardly open chamber and a deployed position wherein said legs project downwardly from said downwardly open chamber when said first internal chamber is oriented to open upwardly;
• a removable container dimensioned and configured to be received and stored within said first internal chamber, wherein said removable container has a second cover dimensioned and configured to close and adhere to said container and to be received within said first internal chamber when said cover is installed on said container;
