Portable container

A portable container, comprising:

• a vessel comprising a peripheral wall defining an open chamber configured to receive and hold one or more goods, a cavity of the peripheral wall filled with a volume of phase change material or thermal mass,
• one or more heat conductive elements extending within the volume of phase change material or thermal mass in the cavity, and
• a base attached to the vessel, the base at least partially housing:
• one or more thermoelectric modules having one side in thermal communication with the one or more heat conductive elements in the cavity of the peripheral wall,
• a heat sink in thermal communication with an opposite side of the one or more thermoelectric modules, and
• circuitry configured to operate the one or more thermoelectric modules,
• wherein the one or more thermoelectric modules is operable to heat or cool the chamber.
