Battery-powered portable cooler

A battery-powered portable cooler comprising:

• a main body including a tub configured to receive contents, a cooling compartment, and insulation at least partly surrounding the tub;
• a lid configured to open and close to selectively provide access to the tub;
• a wheel supporting the main body on a support surface;
• a user interface;
• a refrigeration system including:
• a compressor located in the cooling compartment,
• a condenser located in the cooling compartment,
• an expansion valve located in the cooling compartment, and
• an evaporator including evaporator coils at least partly surrounding the tub to conductively cool the contents of the tub;
• an electronic control unit operably connected to the user interface, the electronic control unit configured to receive input from the user interface and control operation of the refrigeration system;
• a battery receptacle;
• a battery pack configured to mate with the battery receptacle, the battery pack configured to provide electrical power to the electronic control unit, the user interface, and the refrigeration system;
• and
• a fan coupled to a sidewall of the tub, the fan controlled by the electronic control unit and operable to generate a cooling airflow by forced convection within the tub.
